Attach this Dock Roller on the end of your floating dock
gangway. The nylon roller allows the gangway to roll on hard
surfaces with out dragging and making noise. It is made from
hot dipped galvanized 1/4" steel and can be used with lumber
from 1-1/2" to 2-1/2" thick and 8", 10", or 12" high.
The square holes are made for 1/2" carriage bolts.
Be sure to order the appropriate backing plate.
