Boat Trailer 8″ Grey Sydney Rubber Keel Roller with Galvanised Standard Bracket & Clamp Kit – 20mm Bore (SKU: BDA079)

The BDA079 is a heavy-duty 8″ Sydney-style keel roller kit featuring a concave rubber roller and a fully galvanised standard bracket.
It offers excellent support and centering for fibreglass hulls, especially when launching or retrieving on sloped ramps.

The grey rubber roller is UV-stable and slightly soft to absorb impacts without damaging the boat. Its 20mm bore makes it compatible with common 16mm spindles, and its 200mm width is ideal for most medium to large trailers.

The included galvanised bracket with clamp-on stem adjusters (75mm x 50mm) allows for easy height adjustment and secure attachment, no welding required. Ideal for replacing worn-out setups or upgrading support precision.

Specifications:

For those who want simple yet effective keel control, BDA079 is a practical solution that’s built to take on ramps, weather, and years of service.
