Tie Down Engineering Amber 8 Inch PVC Keel Roller, 5/8 Inch Shaft

The Tie Down Engineering 8 Inch PVC Keel Roller (Part No. 86159) guides and supports the hull along the keel of a boat trailer, reducing friction and preventing shifting as the boat is loaded, unloaded, or towed. Molded from an enhanced polyvinyl chloride (PVC) formula, this amber roller is non-marring so it will not mark or mar the hull, while remaining cut resistant and able to absorb shock during loading. Tie Down Engineering notes that its enhanced PVC formula outperforms traditional polyurethane rollers in durability and long-term wear.

This roller measures 8 inches in length and is sized for a 5/8 inch shaft, making it a direct fit for trailers built around that shaft diameter. It mounts along the keel section of the trailer frame to guide and stabilize the boat during loading, helping maintain proper hull alignment and protecting the hull surface across the trailer's cross members. The roller is also offered by Tie Down Engineering in 10 inch and 12 inch amber lengths, as well as 8, 10, and 12 inch black versions, each under its own separate part number, so boat owners can match roller length and color to their specific trailer setup.
