This extruded U.V. Stabilized, polyethylene foam Boat Shield 1007-F bumper is contoured at the back so it can be mounted both horizontally on your dock or vertically on pilings. The beveled edge of the shield helps deflect your boat fenders so they do not catch under the profile of the dock. The light grey color matches up with the natural color of weathered wood. The stainless steel screws and washers are also included with the product. The shield measures out at 48″ long, 2 3/4″ wide, & 5″ high.
