Boat Trailer 8″ Grey Rubber Vee Keel Roller with Galvanised Bracket & Spindle – 20mm Bore (SKU: BDA106)

The BDA106 is a smart balance of softness and stability. This 8-inch grey Vee keel roller is made from 75 duro rubber, offering the perfect grip and flexibility to cradle your boat’s keel without slipping or scuffing.

The Vee shape naturally centers your hull during launching and loading, especially useful on fibreglass boats where alignment and protection matter most. This model features a 20mm bore, suitable for 19mm–20mm spindles, and includes a galvanised steel bracket for easy integration.

It’s a great all-rounder — not too hard, not too soft — for trailer owners who want dependable support across changing ramp conditions.

Specifications:

If your boat trailer needs reliable centering without damaging your hull — BDA106 is the middleweight Vee roller you can trust.
