Polyform USA G-Series inflatable fender. 8-4/5" diameter x 26-4/5" long. Color white. The Polyform G-fenders are blow molded from marine-grade Vinyl material. Intended to be used for typically light-weight utility fenders - but still designed with re-enforcing ribs along the length of the fender body - to assure added strength and abrasion resistance. Over inflation voids manufacturer's warranty.
