Description
Overview:
The Maypole Flat Keel Roller is a durable black rubber roller for boat trailers, built to support and protect the keel during launching, recovery, and transport. With a 127mm face width and a 16mm bore, it offers a stable, flat running surface that helps guide the boat centrally onto the trailer while reducing hull wear. Sized for brackets specified for 51-70mm diameter rollers, it suits common centre-roller setups including MP470 and TR470. The roller fits a 5-inch (12.7cm) bracket with a 16mm spindle and is rated to support up to 380kg when installed and used as intended. It is a straightforward replacement for worn or perished rollers, providing smooth rolling action and reliable protection in regular marine use.
