Our brushes come in the best UV stabilised colour which is BLACK!! In our Residential Strip Brush, our Fire Retardant bristle has a grey tinge to the bristle. That comes from the treatment of the Fibre to be ember resistant, including having a higher melting temperature and also the improved self-extinguishing properties.
Our Aluminium Holders are anodized in a clear colour, so they will be SILVER in colour. You can paint the Ali, however they will need to be primed with an “etch primer”. This is readily available in tin or spray paint from your local hardware store. Then you can paint them in your colour of choice. We found using Spray paint works well.
Alternatively, you can contact your local Powder Coater company to have the Aluminium Holders powder coated in your desired colour to make your Garage Door Colour.

Your local Council will have information regarding the BAL (Bushfire Attack Level) rating for your area and can give you advice regarding sealing your property to meet the Australian Standards AS 3959-2018 Construction of buildings in bushfire-prone areas. Some councils have information available via Google search.
UPDATE – Australian Standards AS 3959-2018 Construction of buildings in bushfire-prone areas – we have confirmed via independent testing our Fire Retardant Strip Brush meets the requirements for homes in BAL rated zones 12.5 up to and including BAL FZ. Our Nylon and Polypropylene Bristle is classified with a very low flammability rating of 1 (maximum of 5 for compliance)
If your property is not BAL rated, then the fire retardant fibre is not necessary. If you are not sure, please contact your local council for more information regarding your specific property. The Fire Retardant Strip has a higher melting point and the bristles are designed to self-extinguish when under Ember Attack.

Flexi Brush Strip® are sold in increments of 1 metre. When you purchase multiple lengths, we will supply this in a continuous length up to 20 metres, unless you specify otherwise.
Our Flexi Brush Strip is manufactured in continuous rolls of between 20 metres up to 50 metres, which is then cut to size per customer order. The Flexi Brush Strip is then rolled into a coil and packaged in a carton for ease of shipping.
To cut the Flexi Brush Strip to your desired length, simply mark the backing at the cutting point. Use pliers to remove a tuft and staple from the backing. Then you will have some clear space to cut the backing with a hack-saw. Removing a tuft will not impact the other bristles. They are all individually staple-punched into the backing.

We have a Kit designed for Sectional and Panel Lift Garage Doors, based on feedback we have received from a number of professional Garage Door installers. Most Garage Door Service companies will fit this brush to the front of the garage door to create the seal. If you would like to fit them behind the garage door to hide the bristle inside the garage, we recommend you consider purchasing our Sample Pack so you can work out what will suit your Garage Door.
Click here for our 4mm Residential Strip Brush Sample Pack
We also have Kits suitable for Roller Doors.
Will the brush seal scratch the roller doors exterior finish or work without any problems with a motorised roller door
The 4mm Residential Nylon fibre is very soft but dense and when installed correctly is not likely to impact on the motor or the exterior finish of the door.
When you install the brush you need it to be just touching the door when the door is closed to create the seal, and preferably on the outer corrugation of the Roller Door. Sealing the bristle within 2mm of the door generally creates a good seal and limits any pressure against the door.
For Roller Doors, we have a NEW Aluminium Holder which has a 25 degree angle. This can be FITTED TO THE DOOR with the bristle just touching behind the Lintel or frame of the door to create the seal. It is designed to fit to the outer corrugation of the roller door, with the angle of the Holder sitting inside the inner corrugation. Then only the bristle is extending outwards and can fold up easily inside the garage door.
We recommend you consider purchasing the 4mm Strip Brush Sample Pack so that you can see the Strip Brush and Holders and “try before you buy”.
Generally, the sides are sealed from the protection of the guides either side of the Roller Door. In most cases you will only need to do the Top Seal for weather protection. For Residential Garage Doors, the 4mm Strip Brush Seals is suitable to protect from draughts, dust, leaves and pests like moths and mosquitos.
Sometimes there may be gaps on the sides of the Roller door where the brickwork and mortar meet the Roller Door guides. In this instance you could use a bonding or sealant to close those gaps in the mortar.
For an ember seal, the best idea is to stand inside the garage with the door closed, and look for gaps where the light gets through. This is where, in an ember attack, high winds could cause embers to penetrate into the garage. It is recommended to seal all of the gaps to within 2mm. For homes in a high Bush Fire Risk area, it would be prudent to cover the sides as well as the Top.
If unsure about protecting your home from ember attack, please consult with your local council for more information regarding local requirements.

It is important to check what is the largest gap when the door is closed, and that is the bristle length that you would need. We would recommend considering using a 45 degree Aluminium Holder fixed to under the Lintel or frame, and angle the bristle downwards away from the gap. When the door is closed, the bristle will just touch the door to create the seal. Where the gaps are smaller, the bristle will settle downwards without overly squashing against the door.
Sometimes, you might find it appropriate to install the Brush Seal in 2 pieces joining in the middle and having the Brush Seal angled like a slight “V” shape. Then you have the ability for the brush to touch the door at the largest gap and then fit the brush seal back a bit at the ends where the gap is smaller. Once installed, it will look less obtrusive than trying to use different size bristle lengths on the one door.
We have a 9mm INDUSTRIAL Strip Brush Sample Pack available to purchase so you can “try before you buy”. The pack comes with a 10cm Sample of each of the Aluminium Holders and a sample of the bristle lengths. The pack also includes the 4mm Residential Strip Brush Sample Pack.

NOTE – THIS CAN BE A TRICKY APPLICATION. Please check your measurements carefully.
You will still need a Strip Brush bristle length that covers the widest gap when the door is closed. Consider using the 45 degree Aluminium Holder so that the bristle is angled away from the gap when the door is opening. We would recommend you consider purchasing our Strip Brush Sample Pack for either Residential or Industrial applications. Then you can check what the function of the roller door would be like when you are operating the door opening mechanism. This is to avoid the bristles getting caught up in the gap and impeding on the door mechanism.
If the gap when opening becomes smaller than 20mm, please proceed with caution and check your measurements carefully prior to ordering your Aluminium Holders and Brush Seals.
If you are unsure, we would recommend you seek advice from a Garage Door Maintenance professional who may be able to make adjustment to the Roller Door. Or you may be able to install a “spacer” or “packer” under the frame. This means the installed Strip Brush would sit lower and keep clear from the roller gap. In some instances, it may be necessary to install the Strip Brush on the actual Roller Door with the bristle then touching the Lintel or frame to create the seal (Available in our Residential range only).
For Roller Doors, we have a NEW Aluminium Holder which has a 25 degree angle. This can be FITTED TO THE DOOR with the bristle just touching behind the Lintel or frame of the door to create the seal. It is designed to fit to the outer corrugation of the roller door, with the angle of the Holder sitting inside the inner corrugation. Then only the bristle is extending outwards and can fold up easily inside the garage door.

There are 2 options to consider:
It might be possible that if you went with a longer brush seal and mounted it higher up the door so that there will only be sufficient bristle protruding below the door so it is just touching the floor to create your seal. Going with a longer bristle means it has more “flick” in it. When the door opens it will crush down against the gap. Hopefully the door would be heavy enough that when the door closes it has enough pressure to cause the bristle to “reverse” against itself and then will settle back into place when fully closed. If it doesn’t have enough pressure behind it, the bristle will be jammed and cause the door to stay open. This would be similar with doors opening onto an incline. You do need to consider the physics of the bristle being able to bend one way and then have enough room to reverse and bend the other way.
There are some products in the market that are spring mounted so that when the door opens the seal is pulled upwards to the level of the door so that it can handle the smaller gap. It is known as a drop down seal. We do not stock this type of seal.
Pesky birds cannot fly through the bristle, however if they have somewhere to perch they can push through. So make sure that you do not have anywhere near the gap that the birds can perch on. And remember to remove the nests, as they will continue to try to get in.
If the gap is smaller than 75mm then the 4mm Residential Strip may suffice. If the gap is larger, then go with the 9mm thick Industrial Strip Brush.
Possums are a pain, as they are territorial and will likely continue to try to get in. We would perhaps recommend you consider our 9mm Industrial Strip Brush in Fire Retardant which has a thicker backing and the bristle is thicker and coarser. The possums don’t like the bristles on their whiskers. But this may still only be a deterrent and not an overall fix. And the bristle may also be heavier on the mechanism of your Garage Door.
We highly recommend you contact a local Possum-man ie Pest Control specialist who may be able to provide you with some advice.

When installing our Strip Brush and Garage Door Seals, please choose a bristle that covers the whole gap. Do not try to use part of the Aluminium Holder to cover, especially if there is a bow in the roller door. You could run the risk of the Aluminium Holder interfering with the smooth running of the door. The Aluminium Holder should be fitted along the frame of the door and not jut out.
STRIP BRUSH Fitting Instructions and Tips
So, for example, if your gap is 45mm, go with a 50mm brush rather than the 38mm brush.
All of our Strip Brush and Aluminium Holders are manufactured and stocked in 3 metre lengths. Anything longer than 3 metres is cumbersome and expensive to freight.
In this instance you would purchase 1 x 3m and 1 x 1.5m length and join them together to make up 4.5m, and then cut them down to 4.3m when you install them.
For the sides of residential garages, you can choose 2.5 metre lengths, and then cut them down to the length required, eg. 2200mm. Also, check in case the sides are 2 different measurements which can sometimes happen! Remember, measure 3 times, cut once.
Our Garage Door Seals are packed onto heavy duty cardboard and wrapped for protection. They are then either inserted into a heavy-duty Cardboard or PVC tube or flat packed. We find this the strongest packaging to withstand the rigours of couriers. Please remember to dispose of your packaging thoughtfully. Re-Use, Recycle, Upcycle.
At up to 3 metres in length, Strip Brush is an awkward product to transport and classified as Oversized or Bulky freight. Many couriers will not accept items over 1 metre, and the others charge a premium for oversize items. We do find placing the items in a Tube provides the strongest Shipping protection, however there is often additional charges from the freight company for manual handling of Tubes.
We offer flat-rate freight to ship this around Australia, to keep our prices down, and to make sure it doesn’t become inaccessible to our regional customers.
One of our customers was very pleased to turn his tube into storage for his fishing rods.
One suggestion is to cut the tube into sections, drill holes in the sides and plant them into the garden near the veggie patch, and use them to collect weeds for composting.
Or you can cut the tube down, put a cap on the bottom, add a hole on the side of the tube and attach it with a magnet to the fridge as a stubby-holder holder!
Please re-use, recycle, upcycle if you can.
We do not recommend trying to trim the bristle yourself. The Nylon bristle is fine, but dense and it is difficult to cut the bristle into an even line. We recommend the Strip Brush Sample Pack so that you can choose the right bristle length first time. If you really need a different bristle length, contact us to discuss a quote for custom cutting.
If the bristle is too long, sometimes choosing the 45 degree Holder allows the bristle to settle better. If the bristle is too short, you may be able to move the Holder over to ensure the bristle just touches the door to create the Seal. The Strip Brush Sample Pack allows you to “try before you buy” and mix and match until you find the right combination for your application.
When you purchase your Strip Brush Sample Pack, you will receive a copy of our Profile Booklet and our Fitting Tips Sheet.

All of our strip brush and aluminium holders are manufactured and stocked in 3 metre lengths. This is for ease of transport.
For lengths over 3 metres, purchase 2 pieces to make up the length required.
For example: for a 5.2 metres double garage we recommend you purchase 1 x 3m and 1 x 2.5m.
We sell the brush strip and holders in increments of 1.0 metre, 1.5 metres, 2 metres, 2.5 metres or straight from stock at 3 metres. We can help you with cut to size lengths. Please Contact Us and we can discuss a quote for custom cutting.
We have a full range of Aluminium Holders and Fire Retardant Brush Strips suitable for most domestic Garage doors, including Roller Doors, Panel Doors, Tilt Doors and Sectional Doors. Suitable for top and bottom seal, and side seals. You can mix and match with our “Choose your options” product listing (type “4mm” in our Search Box). A Sample Pack is available to purchase so you can “try before you buy”.
If your bristles have lost their shape over time or during transport, run hot water (not boiling) over the bristles and flatten them down with a soft towel to help return their memory.

Flue-and-Chimney-Brush-Kits-and-cleaning
For the best clean, choose a Flue Brush Head the same size as the inside diameter of your Flue. a Flue Brush head that is too small will be ineffective; too large may damage the joins and rivets in your Flue.
Our Polypropylene Flue Brush Head is widely recommended for most Flue Cleaning applications. The polypropylene bristles are hard wearing, long lasting and strong enough to give you a great clean. However, it can’t be used when the flue is warm, as the plastic can melt.
The Galvanised Steel brush can be used when the flue is still warm. The major disadvantage is that over time the steel bristles may scratch the inside of the flue, leading to more creosote build-up in the future
For personal use we recommend the polypropylene brush head.
For flues and wood heaters, check out our Flue Brush Range
For chimneys, check out our Semi Professional Chimney Sweep Kit
For Duct cleaning, check out our Professional Brushes
For Coffee Roasters, check out our Coffee Roaster Kits
The Flexi Flue Brush Kit is designed to clean from the bottom up. The Nylon rod is strong but flexible and can handle up to 2 x 45-degree bends. This allows it bend through the wood heater into the flue hole.
You will need to remove the baffle or damper plate to access the opening of the flue. Cleaning from the bottom up can be a bit messier, so be on hand with a vacuum cleaner to suck up any soot that overflows from the heater.
Do not try to bend the rod more than 45 degrees when you are feeding the rod into the Flue. You will need to stand close to the front of the woodheater so that you do not run the risk of the Rod being forced inwards at a larger angle and collapsing. If you are unable to remove the Damper plate, you may need to contact your local Wood Heater service professional for advice.
We do not have any specific instructions, as each wood heater is different. However you may find the baffle plate appears “stuck” due to creosote build up, and a slight tap with a soft mallet may help to dislodge it.
Here is a YouTube video we found that may assist:

Yes, any of our Flue Cleaning Brush Kits can be used from the roof. Simply feed the Flexi Flue Brush head down the Flue to the bottom and pull back up again. No pushing or jiggling required.
Our Flexi Flue Brush Kit can handle up to 2 x 45-degree angles in the flue. Take care to not force the brush, as this may dislodge sections of the Flue. If unsure, obtain some advice from your local Chimney Sweep. Alternatively, using our Flexi Flue Brush Kit, you can clean one bend from the roof and the other from the ground.
It might be an idea to consult with a Chimney Sweep professional or Flue Installation specialist to consider whether a “port” could be installed into the Flue. This would allow you to insert your Flue Cleaning Brush and Rod in between the 45 degree bends for easier access. You can then clean downwards and then upwards.
When you have more than a 21ft (6.3m) Flue to clean, it might be an idea to consult with a Chimney Sweep professional or Flue Installation specialist to consider whether a “port” could be installed into the Flue. This would allow you to insert your Flue Cleaning Brush and Rod half way up the Flue. You can then clean downwards and then upwards, with less length to cover.
There is a chance this Rod could get caught up inside the bend due to the Ferrules at each end of the Rod. Also, the twisted wire is not designed to be over compacted when trying to push through angles. We would recommend you consider using our Flexi Flue Cleaning Brush Kit as it contains a continuous Nylon Rod designed to go around up to two 45 degree bends. For a heavy duty option, we would recommend the Professional Chimney Rods (R900) that are in 3 foot lengths and joined end to end with Brass fittings to also handle Flues with bends. You will need a UA1 Universal threaded adaptor with the Chimney Rods so you can connect the Rod to any of the 1/2 inch BSW fittings on our Flue Cleaning Brush Heads.
I measured my Flue and the diameter is half way between a 5.5" (140mm) and a 6" (150mm) dia. Which size should I choose?
In this instance, we would recommend going with the larger size diameter. When you first clean your Flue, take it slowly and gently as you don’t want to run the risk of the Flue Brush getting stuck inside the Flue. If you find it too tight, you can trim the bristles down with a decent pair of scissors so that it fits your Flue size.
We have a Kit specifically available for cleaning Coffee Roaster Flues. Given the nature of the build up, a more heavy duty Kit is recommended. Coffee Roaster Flue Cleaning
All of our Kits are designed for Manual cleaning. No need to fiddle with Power Drills, particularly on the roof. Purchasing the right size Flue Brush Head so that it fits the diameter of the Flue is important, as it means all you need to do is feed the Flue Brush into the Flue without needing to overwork the Rods. Simply feed the Flue Brush Head and Rods into the Flue and then draw it out again. Give it a shake and repeat if you believe it is needed. This gives you the best clean and is less likely to dislodge rivets or screws that hold the sections of Flue together.
Would you have something for cleaning the grease off round kitchen exhaust ducts using a flex shaft?
Our brushes are generally for manual use, as they might be too heavy for a Flex Shaft. You would need to check your User Manual.
Here is the link to our Professional Cleaning Brushes. For manual use, we recommend our Professional Rods, and you would need a UA1 adaptor to make up the Kit.
ROCK-OFF-Towing-Brush-Strip
We are a small, family-owned manufacturing company here in Melbourne. We do not have any representation interstate.
We sell directly from our Melbourne manufacturing facility. This is BRUSH ONLY and a DIY application, you will need to source your bracket and fixing. Please refer to our Product description and our FAQ’s.

I have a Toyota Hilux 4 X 4. What would you suggest is the minimum distance I should mount the brush away from the outlet of the exhaust pipe?
The best option is to mount the brush under the exhaust or behind the exhaust. We recommend you contact a local exhaust specialist for advice.
Remember this is a plastic bristle brush, so needs to be mounted away from the exhaust pipe. Both the heat of the exhaust pipe and the hot fumes that come from it can distort the bristles.
You can remove the tufts of the brush that sit in front of the exhaust to provide clearance. The tufts are “stapled” into the backing of the ROCK OFF, so you can use pliers to remove the individual tufts without impacting the overall brush.
If you are unsure of how to fit your ROCK OFF, we recommend you contact your local 4WD after market specialist, trailer specialist or engineer/fitter. who could give you some advice as to the best way to fit to your vehicle.
Not sure which option is best for you? Please Contact Us and our friendly team will be happy to help.
Thanks Stephen Dyer and Signs Plus for their helpful video on mounting our ROCK OFF Towing Brush Strip to their Hi Lux. https://signsplus.com.au/contact-us/ Check it out here https://youtu.be/Ep_LOtGifJY
(NB. Busy Bee Brushware and Signs Plus do not have any commercial affiliation)
Your ROCK OFF is made with a heavy duty backing, however plastic does not have a “grain”, so if you are mounting the ROCK OFF from the back of your vehicle, it will need some structural stability. Mounting the ROCK OFF without this additional structure could mean that, when driving at higher speeds, the ROCK OFF could shudder or vibrate.
We recommend fitting your ROCK OFF to a metal channel or angle bracket. You can drill through the upper part of the backing of the ROCK OFF and bolt it directly to the metal. Once in a metal bracket, you can fix to the rear of your vehicle where needed.
For areas under your caravan or Motorhome, you can bolt this directly to the chassis where there is already a solid structure. Where you have a towing vehicle behind your caravan or motorhome, you can fix your ROCK OFF in the same way.
If you are not sure, we recommend you seek advice from a Towing or Trailer specialist.
Busy Bee Brushware manufactures and sells the Rock Off® Towing Brush Strip. You will need to source your own fitting as a DIY project.
The backing of our Brush is heavy duty HDPE, however is does not have a grain, which means that it needs some structural support if you are fitting the brush to the back of your vehicle.
We recommend you contact your local 4×4 after-market specialist, trailer specialist or engineer/fitter who could give you some advice as to the best way to fit to your vehicle.
Our ROCK OFF® Towing Brush Strip can be drilled and fixed to an Angle Bracket or a C Channel for mounting behind your vehicle.
The ROCK OFF® Towing Brush Strip can also be cut into sections and mounted under the caravan as a secondary protection zone for your caravan’s pipework. You can bolt the brush directly to the chassis of the caravan/trailer.
The standard lengths available are 1200mm, 1500mm, 2000mm, and 2400mm.
When you measure your towing vehicle or caravan or motorhome, we recommend the size of the ROCK OFF should be no longer than the width of the vehicle. This is to meet the Australian Standards requirements for towing. You do not want the ROCK OFF protruding as this will create its own airflow drag, and also increases the risk of you or your family catching yourselves on the edge.
Our ROCK OFF Towing Brush Strip is made in a 2-row staggered brush pattern to give the brush a dense coverage. If you need to cut the brush length to size, we recommend you mark the place where you need to cut. Then using pliers, remove the bristle tuft immediately underneath. That will give you a clear space to cut the backing with a hacksaw or dropsaw. The bristles are individually “staple-punched” into the backing so pulling out one tuft will not impact any of the other tufts.
We offer standard Brush lengths of 1200mm, 1500mm, 2000mm and 2400mm.
We recommend you choose the next size up and you can cut the backing to the length required.

Measure from the top of the Mounting point to the ground, take off 100mm for clearance from the road, and then another 45mm for the backing of the brush. That will be your bristle length needed.
We generally recommend approx 100-150mm for clearance to the road. If the vehicle goes over ruts, you do not want your ROCK OFF to hit the ground, thereby creating it’s own kick up of dust and stones.
MEASURE THREE TIMES BEFORE YOU ORDER. PLEASE DO NOT EXPECT TO CUT THE BRISTLES, YOU WILL FIND THIS NEAR IMPOSSIBLE!!
If you are unsure of how to fit your ROCK OFF, we recommend you contact your local 4WD after market specialist, trailer specialist or engineer/fitter. who could give you some advice as to the best way to fit to your vehicle.
Not sure which option is best for you? Please Contact Us and our friendly team will be happy to help.
As a general guide, we understand the following:
Series 100 – 2000mm x 400mm
Series 200 – 2000mm x 400mm
There is no one size fits all, as it depends on where you are going to mount the ROCK OFF Towing Brush Strip.
How long do the bristles need to be?
When measuring the trim length that you need, when we refer to Brush trim, that is the exact length of the bristle. You will need to add the length of the backing to that measurement when considering overall length. Our customer feedback is that the brush is most effective when mounted with anywhere from 100mm to 200mm clearance from the road. Minimum clearance is required so that the brush does not hit the ground and create its own stone kick up.
Remember:
This is a plastic bristle brush, so needs to be mounted away from the exhaust pipe. Both the heat of the exhaust pipe and the hot fumes that come from it can distort/melt the bristles.
The Landcruiser 200s has been a difficult one to provide options for, due to where the reversing sensors, spare tyre, exhaust and the Anderson plugs are located. Unfortunately, we do not have a stock configuration that works so far. You would be best to consider speaking to a caravan or trailer service company who could help with some advice.
Your option might be to look at the Rails and Brush only option, and make up your own bracket to fix to the underside of the vehicle. You will need to get it lower than the Anderson plugs and this would also mean it would sit under the exhaust which is a good thing. This would leave a gap above the ROCK OFF where stones could still kick through. Some of our customers have countered that by adding a brush or rubber to the top of the ROCK OFF that reaches upward towards the bumper of the vehicle to cover that gap.
We have also received feedback from customers that they installed the “Stone Stomper” to their vehicle and then used our ROCK OFF as a secondary protection at the front of the caravan or underneath to protect their pipework and suspension. (We are not affiliated with Stone Stomper and make no representations in relation to this product). You may find discussion of stone guard protection on Caravan forums that might give you some insights.
Disclaimer: It is your responsibility to ensure this product is suitable for fitment and use with your intended towbar and vehicle (vehicle includes Caravans, Trailers, Motorhomes).
When measuring the trim length that you need, when we refer to Brush trim, that is the exact length of the bristle. You will need to add the length of the backing (45mm) to that measurement when considering overall length. Our customer feedback is that the brush is most effective when mounted with anywhere from 100mm to 200mm clearance from the road.
Minimum clearance is required so that the brush does not hit the ground and create its own stone kick up.
Remember:
This is a plastic bristle brush, so needs to be mounted away from the exhaust pipe. Both the heat of the exhaust pipe and the hot fumes that come from it can distort the bristles.
Convert to side pipes if you can, or contact us to discuss your exhaust placement.
ROCK OFF® is lighter, creates less drag and allows greater airflow than traditional solid mudflaps.
Our customers have also found that when a stone hits a solid mudflap it can bounce off, while the ROCK OFF® bristles absorb the impact of the stone and takes the energy out of the bouncing stones and rocks. Means less risk to you, less risk to other drivers and less impact on the environment.
Helps to prevent damage to the front of your camper trailer of caravan, can also be fitted under your caravan to help protect your tanks, pipework and suspension.
We offer standard Brush lengths of 1200mm, 1500mm, 2000mm and 2400mm.

If you need to cut the brush length to size, we recommend you mark the place where you need to cut. Then using pliers, remove the bristle tuft immediately underneath. That will give you a clear space to cut the backing with a hacksaw or dropsaw.
We do not recommend trying to trim the bristle yourself. The Polypropylene bristle is dense and it is difficult to cut the bristle into an even line. We have bristle lengths from 150mm in increments up to 400mm maximum.
This is a plastic bristle brush, so do not try to trim the brush with an angle grinder as this will distort the bristle. If you do need a different bristle length, contact us to discuss a quote for custom cutting.
Measure twice, three times! Recheck that you have allowed for 100mm clearance from the road, allow for the 45mm backing, and allow for any weight distribution when the caravan/trailer has been hooked up.
While looking similar, ROCK OFF and truck spray suppressant are different products with different purposes (although we do sell both – here is the link: https://busybee.com.au/product/wheel-whiskers-ww1-spray-suppressant
Truck and bus spray suppressants are designed to reduce the amount of water picked up by trucks and improve visibility for other road users. It has softer bristles and a flexible backing to fit around truck wheels.
Regular Spray Suppressants have a backing of 9mm, whereas our
ROCK OFF® is a strong HDPE backing measuring 45mm high by 25mm thick. This allows for the thicker fibre and double the bristle of a conventional spray suppressant.
Beware of cheap imitations. Our ROCK OFF is specifically designed to deflect stones. It is a lot stronger than spray suppressants which are designed for water, not the rigours of off-road driving.
ROCK OFF® is made with crimped anti-static polypropylene fibre (1mm/0.040”), punched into a HDPE (High Density Polyethylene) backing. Our backing has holes drilled into it and our semi automatic machines “staple punch” the bristles securely into the backing.
We source all our materials from local suppliers and the brush is made at our factory in Dandenong South, Melbourne. Where possible, we source recycled HDPE for our backing.

Roof-Gutter-Brush
When you place the 1 metre lengths of Gutter Brush into your guttering, it can create a barrier so that leaves or other debris will blow off the Gutter Brush and cannot accumulate inside your guttering. Rain can still get through the bristles so that your drainage is not impacted.
You need to measure the width of your guttering. This will determine the diameter size of the brush you need.
For example, if your guttering measures 120mm x 120mm, go with the 125mm diameter. The 110mm dia might be too loose and leaves could still fall down the side of the Gutter Brush, so a firmer fit would be recommended. Sometimes the gutter brush might be visible above the guttering, but as a black bristle brush it is generally not too noticeable.
Our Gutter Brush is manufactured in 1 metre lengths for convenience of shipping. You simply lay them end to end inside your gutter. You can bend the brush so that it can go around the corners or your guttering. It can also be pressed under the tiles to help keep out pests.
Lay the Gutter Brush so the ends press into each other, the single pieces will remain in place in your roof guttering.
You can also install a small section of gutter brush in the down pipe to leaves. Bend the rest of the length into the gutter. Only feed a small section, approx. 20cm, into the pipe so it does not impede the flow of water.
Lay the Gutter Brush end to the end so the twist wire ends press slightly into each other, the single pieces will remain in place in your roof guttering.
We recommend that once a year you still clean your gutters. Simply lift out the pieces of Gutter Brush, give them a shake, sweep or hose out the gutter and replace the Gutter Brush. This will remove any smaller build up or dust that may collect under the brush.
Simply push the gutter brush into any open crevices to deter the bird or animal from getting in. They do not like the strong bristles.
Take advantage of our Full and Half Boxes of Gutter Brush, with a discounted price built in.

If your bristles have lost their shape over time or during transport, run hot water (not boiling) over the bristles to help return their memory.
Rack Off ® Gutter Brush does not weigh much, but they take up a lot of room in a carton, which largely increases the cost to freight this product. They are classified as “oversize” freight.
We offer flat-rate freight to ship this around Australia, so it doesn’t become inaccessible to our regional customers.
Wash-Brushes
We have step by step pictures on our Website. There is a piece to unscrew from the Detergent Dispenser, then you screw it to the Pole and the end clips onto your normal hose nozzle. You will have one piece left over when done.
Wire-Brushes
We recommend using our Professional Chimney Rods, strong but flexible Polypropylene Rod with Brass fittings and 1/2″ BSW thread. Can be screwed end to end for longer lengths. You will also need to purchase a UA1 Brass adapter which has the 1/2″ BSW fitting.

We have a Professional Coffee Roasters Flue Cleaning Kit available that is suited for this application. The heavy duty Boiler Tube brushes have the potential to scratch the inside of the Stainless Steel Flue which can create more creosote build up. Brass brushes would be more suitable for this application than Steel. Our Professional Coffee Roasters Flue Cleaning Kit contains heavy duty Polypropylene brush heads suitable for this application.
We have Professional Chimney Rods that are ideal for larger size Boiler Tube Brushes. You will also need a Universal Adaptor UA1 to attach the Chimney Rod to your Boiler Tube Brush
Skylight-Diffuser-Replacements
Jigsaw time! Arrange the pieces as best you can into shape, then trace or measure your diffuser.
For circles, trace onto paper, then fold the circle in half to find the diameter.
The Skylight Diffusers are custom cut from 3mm thickness Acrylic Plastic Sheet. The “colour” is Opal Frost which provides a soft glow.
Select a larger size, e.g. if you need 460mm, then select a 500mm dia Round. When you go to the Checkout, there is a box available for your comments and you can specify that you require your Diffuser to be 460mm dia Round.
Provided you are fitting your Skylight Diffuser replacement into a solid frame, it is generally strong enough to hold up without sagging.
We specialise in FLAT sheet Acrylic only, but we can do custom sizes to make it easy to fit your existing Skylight surround. We recommend you google “Dome Skylight Diffusers” to locate a supplier in your local area.
This type of plastic is called “prismatic”, and is mainly used for commercial purposes. We use a flat plastic Acrylic sheet which provides a softer glow and a lifts the appearance of your home to a more modern look.
We do not supply the prismatic sheet, so if you need to match your Skylight Diffuser replacement to match other existing prismatic diffusers, you will need to google search “prismatic acrylic” to find a supplier in your area.
We package the Skylight Diffuser between 2 square pieces of heavy-duty cardboard and seal the sides totally for protection. We use either Australia Post shipping or Courier Shipping.
This is not our area of specialisation. We recommend you google “Skylight replacement surrounds” to locate someone in your local area.
There should be a plastic film on both side’s of the skylight that can make it looked scratched. Have you peeled these of yet? Sometimes the film can be hard to notice!! If you have trouble removing the file, try sticking some tape near the edge to lift the film and peel off.

NOTES FOR MACHINING NYLONS, ACETALS, PVC and PETP (for diameters > 90mm)
Please note the following guidelines to reduce the risk of stress cracking or splitting!!!
- Heat generated by cutting tools can lead to the release of processing stresses so it is important for coolants to be used.
- When turning, using carbide tipped tools as used to aluminium and alloys, deploy a clearance angle of 6-10 degrees, a positive rake angle of 0-5 degrees and a side angle of 45-60 degrees.
- Drill a pilot hole of maximum 12mm using 500-800rpm and a positive feed of 0.5mm per revolution. It may be required that negative relief on the drill cutting edges be applied.
- Secondary drilling at 400-500rpm at 0.20mm to 0.50mm per revolution is required to expand the hole to larger diameters to accommodate a boring bar.
- When boring and turning a feed rate of 0.10mm to 0.30mm is recommended.
