Tie Down Engineering Amber Bow Roller, 4 in., 1/2 in. Shaft, Part 86142

The Tie Down Engineering Bow Roller, part number 86142, is a 4 inch amber roller built for 1/2 inch shaft boat trailers. It centers the boat during loading and cushions bow contact with the trailer's bow stand, helping prevent damage from bolts or brackets and reducing impact during transport. The roller acts as a buffer for the boat's bow, providing a soft, cushioned surface that reduces impact and lowers the risk of scraping or scuffing the hull against the roller bracket or trailer hardware. It also assists in aligning the boat on the trailer, helping center it and preventing bow-to-bow-stand contact during loading and unloading, which makes the process easier while helping maintain balance and stability on the trailer.

Constructed from polyvinyl chloride (PVC), the roller is built to support the weight of the boat on the trailer and absorb road shock for a secure, stable ride over rough roads or uneven terrain. This is the complete assembly, including the roller, end bells, nuts, and two washers, sized for a 1/2 inch shaft and designed to fit standard 4 inch bow roller mounts on boat trailers.
