Protect your investment with Techstar dock bumpers. The BB-7 and BB-9 work with new docks or will easily retrofit most existing docks. Molded in lengths just under 4 feet, the 7 inch height will cover the end of your decking as well as a complete 2x6 frame. The 9 inch will complete a 2x8 frame with 2x6 decking. A full 3” of protection between your dock and boat gives you peace of mind.
