Stoltz RP-444 Polyurethane Marine Bow Roller Assembly - 3-7/8" Wide to fit a 1/2" Shaft

This is an assembly of a 4" center roller. It mounts on the winch stand on the front of the trailer. The assembly is meant to be the roller with which your boat will make contact every time you load, trailer and unload. The large end bells help guide and direct the bow of the boat to the center while snugging it up tight to the bow roller, ensuring correct placement for trailering. The end bells also help prevent the bow of the boat from making contact with the winch post arms, which can damage the hull of the boat.
