Flat Keel Roller + Bracket 16mm Bore

Maypole Bracket & Flat Keel V Roller Assembly – 16mm Bore – Boat Trailer Support Kit

The Maypole Bracket & Flat Keel V Roller Assembly is a heavy-duty, marine-grade support system designed to provide reliable guidance and protection for your boat's keel during launching, recovery, and transport. Supplied as a complete assembly, it combines a non-marking polyurethane flat keel roller with a heavy-duty zinc-plated steel bracket, offering smooth operation and long-lasting durability in demanding marine environments.

The flat polyurethane keel roller is manufactured from high-quality, non-marking material that cushions and supports the hull without causing scratches or damage. With a 127mm width and a 16mm bore, it rotates smoothly on the supplied 16mm solid steel spindle, helping guide the boat safely onto the trailer while reducing friction and wear.

The robust bracket is manufactured from 50mm × 6mm clear zinc-plated steel strip, providing excellent strength and corrosion resistance for both freshwater and saltwater use. Slotted mounting holes accommodate M10 fixings (not included), allowing adjustment during installation to suit a wide range of trailer configurations.

Designed to accept compatible Maypole keel rollers, this complete assembly is an ideal replacement or upgrade for boat trailers requiring dependable keel support.
