Protect your boat, jet ski, and dock from bumps and scrapes with these KEMIMOTO dock bumpers. This 2-pack comes with two ropes for hanging. They're made from thick, high-impact closed-cell foam that absorbs shock really well. The unique two-part design (one large, one small piece) lets them fit snugly on straight dock edges or corners. You can install them horizontally on the dock with screws, or hang them vertically on your boat/PWC using the holes and ropes. They're recommended for personal watercraft (PWC) and boats up to 25 feet long (use two for a jet ski, or one per 10 ft of boat length). A simple, effective way to prevent costly damage. Essential for any dock or boat owner.
