The Big B Fender's adaptable design includes a center rope tube that allows end-to-end line passage. It can be hung horizontally or vertically with a single line. Horizontal hanging provides protection from pilings, tricky docking circumstances, and tidal change zones. Big B Fenders are made of seamless material with molded ribs to reduce roll. It's composed of high-quality marine vinyl and has a high gloss finish. Key Features: The center hole is 3/4" dia. and accepts up to 5/8" dia. rope for tying down the fender. Seamless, flexible marine-grade vinyl construction with molded ribs (marine-grade vinyl lasts years in the sun). It can be hung horizontally or vertically with a single line. Needle-valve for simple inflation and long service life. Guaranteed against splitting or bursting.
