Boat Trailer 6″ Red Poly Sydney Keel Roller with Galvanised Standard Bracket & Clamp Kit – 17mm Bore (SKU: BDA038)

The BDA038 is a precision-designed 6″ Sydney-style red polyurethane keel roller kit with standard bracket and clamp-on adjusters. Ideal for fibreglass boats, the concave roller profile helps centre and guide the boat keel smoothly into position.

The roller’s UV-stable red polyurethane offers soft, non-marking contact, especially suited to delicate hull finishes like gelcoat or painted fibreglass. It features a 17mm bore, compatible with 16mm spindles.

The hot-dip galvanised steel bracket provides excellent corrosion resistance, while the clamp-on stem adjusters (75mm x 50mm) make installation flexible, fast, and weld-free.

Specifications:

A premium kit for boaters who want smoother keel alignment, softer contact, and easy install—all wrapped in bright red.
