The Galv-A-Dock Vertical Boat Bumper offers maximum protection for any type of boat. It protrudes four feet upwards above the dock surface and two feet below the dock decking surface. The Galv-A-Dock bumper offers protection for many boat types, from low-profile fiberglass bass boats to large, wide-body cruisers. The Galv-A-Dock molded plastic bumper is durable and is designed to cushion impact. Any severe wear and tear is to the Galv-A-Dock molded plastic bumper itself, sparing the boat from damage. Galv-A-Dock offers a corner bumper for outside corners of the dock where the boat may contact the upright post. The Galv-A-Dock molded bumper is the best bumper available in the industry—it’s durable, user friendly, aesthetically appealing, and the longest lasting bumper-protection material available.
