Introducing the MAMDAFAON Boat Trailer Rollers and Guides – an indispensable part of your boat trailer accessories collection. These boat parts, perfectly designed for keel, spool, or bow roller, ensure maximum convenience by providing an enhanced boat-to-roller contact area. Crafted from premium quality black rubber, the roller end cap is a testament to durability and longevity. It is conveniently sized with a 3.14" diameter x 1.15" dimension with a 5/8" ID hole, making it a perfect fit for your boating needs. Installation is a breeze, as these boat trailer rollers and guides easily mount onto the same bracket as the roller. These boat trailer accessories serve as a protective barrier for your hull against sharp bracket edges, contributing to your boat's longevity. Plus, they resist oil, fuel, and salt corrosion and absorb the shocks of launching, loading, and hitching.
