The SoftSide Pontoon Fender is uniquely shaped to provide protection from the edge of the boat deck to the widest point of the pontoon, minimizing contact damage to the boat and dock. The fender slips easily underneath the deck edge and secures between it and the top of the pontoon. Included side-loop strap can be used to mount fender more securely, but is not required.. Fender rests securely between boat deck edge and pontoon. Included mounting strap helps provide secure fit. Lifetime guarantee against chalking, splitting, marring, deflating and crushing.
