The Heavy Duty Dock Roller Assembly from Tie Down Marine aids the natural motion of a dock due to the constant change in tides. The complete assembly is sold in two parts: a heavy duty roller with included bolt and a galvanized bracket.

The roller measures 6" long and rotates on a 5/8" diameter shaft. It can mount directly to the dock or to the optional deck plate. The hot-dip galvanized bracket measures 3/4".
