This 8-inch Polyurethane Self-Centering Roller Kit is the perfect choice for fibreglass boats needing gentle yet firm keel alignment during launch and retrieval. Designed with non-marking UV-stable polyurethane, it ensures your hull stays scratch-free while providing strong centering action.
The roller has a 203mm width and 17mm bore size, fitting perfectly with a 16mm spindle. It comes with a standard galvanised steel bracket and 75mm x 50mm clamp-on stem adjusters for flexible and secure mounting to your trailer frame.
Unlike traditional fixed systems, this setup allows you to fine-tune the roller height and alignment using the adjustable stems, offering better support and protection for fibreglass hulls during both loading and towing.
