Domar Keel Roller + Bracket 16mm Bore

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

The Domar & Maypole Bracket & Flat Keel Roller Assembly is a heavy-duty, marine-grade support system designed to guide, cushion, and support 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, providing dependable performance and long-lasting durability in demanding marine environments.

The flat polyurethane keel roller is manufactured from high-quality, non-marking material that supports the keel while helping protect the hull from scuffs, scratches, and abrasion. Measuring 128mm wide with a 16mm bore, the roller rotates smoothly on the supplied 16mm solid steel spindle, reducing friction and allowing easier boat loading and unloading.

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

Suitable for replacement or new trailer builds, this complete assembly provides reliable keel support for safe transport and effortless launching.
