Boat Trailer 8″ Grey Rubber Vee Keel Roller with Galvanised Standard Bracket – 20mm Bore (SKU: BDA107)

The BDA107 is the refined version of our mid-range Vee roller — now paired with a standard galvanised bracket for extra rigidity and precise keel alignment.

Built from 75 duro grey rubber, this 8″ Vee roller cradles your boat’s keel securely during launch and retrieval while remaining gentle on painted or fibreglass surfaces. The Vee shape guides the keel centrally, reducing misalignment and trailer bounce.

Featuring a 20mm bore and a non-marking rubber construction, it’s ideal for owners who want reliable, practical performance without scratching up their boat.

Specifications:

If you’re after reliable centering, no-fuss installation, and hull-safe rubber — BDA107 might be your keel’s new best friend.
