The 91331 8" Blue Nylon Self-Centring Roller is a hard-wearing boat trailer roller designed to support the keel and help guide the boat towards the trailer centreline during retrieval. Measuring approximately 203mm / 8" wide with a 17mm bore, its hard blue poly/nylon construction provides excellent wear resistance. The shaped self-centring profile makes it particularly suitable for aluminium and alloy boat trailers.
