How to order the correct kit length:

• Measure your vehicle from outside wheel to outside wheel

ROCK OFF^® can be used in conjunction with most common caravan/trailer chains and electrical fittings, allowing you to maintain full brush coverage across the entire width of your towing vehicle.

Available bristle lengths:

1. 150mm (suits mounting height of 295mm or more)
2. 200mm (suits mounting height of 345mm or more)
3. 250mm (suits mounting height of 395mm or more)
4. 300mm (suits mounting height of 445mm or more)
5. 350mm (suits mounting height of 495mm or more)
6. 400mm (suits mounting height of 545mm or more)

How to determine your ideal bristle length:

1. Your bristle length should be at least 145mm shorter than the distance from the top of your mounting point to the road when fully loaded
2. Measure the distance between the top of the mounting point on your vehicle, caravan or trailer, and the road
3. Deduct at least 100mm for road clearance and a further 45mm for the brush backing, total 145mm
4. For example, if your total distance from mounting point to the road surface is 400mm, then you will need a bristle length of 250mm, and your clearance to the road would be 105mm

U Bolt mounts can accommodate U Bolts up to an outside width of 130mm.

EXHAUST KIT OPTIONS AVAILABLE NOW

NOTE: ROCK OFF^® Towing Brush Strip is a Polypropylene (plastic) construction and must be mounted well clear of your exhaust pipe to avoid damage. Heat from the exhaust pipe and hot fumes can distort the bristles.

For best results, mount the brush under the exhaust or behind the exhaust.

Have an exhaust pipe in the way? Check out these solutions:

Straight exhaust pipes:

Straight pipes are ideal and do not typically require an Exhaust Kit option. This applies to straight exhaust pipes either above the brush mounting area or side pipes facing away from the mounting.

Angled exhaust pipes (within 150mm of brush mounting are):

When your pipes are angled downwards and within 150mm of the brush mounting area, choose our Exhaust Shield Plate.  This fitting has stainless steel open shield plate to be fitted in front of your exhaust pipe so exhaust heat and fumes are drawn into the open area and away from your vehicle. Towing Brush Strip bristles are individually stapled and can be removed with pliers to accommodate fitting the Exhaust Shield Plate over the Stainless Steel Rails and in front of your exhaust pipe. Your Exhaust Shield Plate is fitted with a smaller piece of Towing Brush Strip to cover the gap under the plate.

Angled Exhaust Pipes (150-500mm from brush mounting area):

Further, if your exhaust pipes angled downwards and located between 150mm and 500mm (max) away from the brush mounting area, choose our Exhaust Extension Kit. The Exhaust Extension Kit includes Exhaust Shield Plate plus 500mm of Stainless Steel Truck Flex Tube in sizes 2.5″ (60mm) or 3″ (76mm). Truck Flex Tube allows fitting over your exhaust pipe with exit via the opening in the Exhaust Shield Plate. Also includes a coupling to fit over your exhaust pipe, and a stainless steel fitting to keep Flex Tube in place. This allows exhaust gases to flow away from under vehicle and not impact Towing Brush.
