Patent Design: The ergonomic design and environmental materials make our boat fenders for docking unlike traditional fenders, ours do not require inflation, eliminating any air leakage problems and enhancing reliability and durability. To further ensure longevity, we have incorporated reinforced nylon ropes with a fixed buckle, providing additional protection and sturdiness, particularly during stormy weather. Strong Protection: These boat dock bumpers are molded in a cross-linked closed-cell foam that is extremely long-lasting, it won’t degrade during prolonged exposure to the sun. The extra-long strap is easy to loop over higher attachment locations, and the dock bumpers will keep your boat from getting scratched and damaged when tied up at the dock and around other boats. Quick Installation: The integrated strap ensures effortless connection to the dock. Simply connect and lock it, eliminating the need for complex knots. The locking feature expedites the installation of boat bumper fenders. Size Choosing: kemimoto boat fender for docking size: 17in (length) * 8in (dia).
