This black inflatable boat bumper, with a size of 51 x 14 cm, has a smooth design in high-gloss finish. It brings maximum mooring protection to boats when tied to cleats or rails. The reinforced eyelets on both ends allow you to hang the boat bumper either vertically or horizontally with thick ropes. Made of PVC, it is endowed with superior strength and durability for years of use. Delivery includes 4 boat bumpers and one pump. Reminder: Once the boat bumpers have air in them and are formed, use 1-2 more pumps, and your boat bumpers are ready to use. If using an air compressor, there should be about ½ inch squeeze in the boat bumper. Never overfill your boat bumpers!
