The only fenders specifically designed for maximum protection when rafting or tying up against solid walls. Unique rectangular cushions provide greater protection than other conventional fenders from boats jarring into one another. Six molded tubes provide crush resistance, and the exclusive-channel design lends itself to "hugging" the boat. Made from tough, marine-grade vinyl, fenders feature an inflation valve for air pressure adjustment. Hang vertically or horizontally. They make great piling cushions and are extremely comfortable as seat cushions.
