Boat Trailer 8″ Blue Poly Vee Keel Roller with Galvanised Standard Bracket – 17mm Bore (SKU: BDA101)

The BDA101 is your go-to keel guide for mid-sized boats — an 8″ concave blue poly roller paired with a **standard galvanised bracket** and clamp-on adjusters. With its Vee shape, this roller naturally centers the hull, preventing side slippage and making your launch and retrieval a breeze.

Crafted from high-quality non-marking blue poly, it’s UV-stable and tough enough to handle frequent use while staying kind to your hull finish. Ideal for alloy or fibreglass boats, the 17mm bore is designed to fit snugly onto a 16mm spindle.

This kit includes the roller, a hot-dip galvanised steel support bracket, and adjustable clamp-on stem mounts (75x50mm) for versatile installation.

Specifications:

Simple, strong, and straight to the point — the BDA101 keeps your keel on track every time.
