The 91324 8" Blue Nylon Concave Roller is a hard-wearing boat trailer centre roller designed to support and guide the keel during launching and retrieval. Manufactured from blue HDPE/nylon-type polymer, its concave profile helps locate the hull on the trailer while providing a low-friction rolling surface. The roller measures approximately 203mm / 8" wide with a 17mm centre bore, making it suitable for compatible keel roller brackets and spindle assemblies.
