In keeping with the Polyform tradition of quality, the HTM (hole-through-middle) boat fender was designed to provide maximum protection in a wide variety of applications. Vertical ribs for extra protection, reinforced tube ends to prevent lines from pulling through if the fender gets caught in a tight spot, and extra wall thickness to resist punctures and tears are just a few of the features this high-quality fender has to offer. The HTM Series fender is designed to provide protection and stand-off for larger vessels between 20 to 50 feet in length. Choose from 4 sizes and a variety of Polyform colors.
