Tie Down Engineering 86284 Amber 4 Inch PVC Keel Roller, Spool Type, 5/8 Inch Shaft

The Tie Down Engineering 86284 is a 4 inch amber PVC keel roller of spool-type construction, designed to support and guide the keel of a boat as it is loaded onto or off of a trailer. The roller is molded from Tie Down Engineering's enhanced polyvinyl chloride (PVC) formula, which the company states outperforms traditional polyurethane rollers in wear resistance and shock absorption. The non-marring PVC surface rolls smoothly against the hull without marking or marring the gelcoat, while the material's cut resistance and shock-absorbing properties help protect both the hull and the roller itself from damage during repeated loading cycles.

This roller measures 4 inches in diameter and is built for a 5/8 inch shaft, making it a direct fit for trailer keel roller assemblies sized to that shaft diameter. The spool-type profile centers the keel as the boat moves along the bunks or rollers, reducing side-to-side shifting and helping distribute the hull's weight evenly across the trailer's cross members during transport.
