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.

Despite every effort to accurately depict each product’s color when reproduced, color differences may arise from color monitors and print capabilities. The screen images are intended as a guide only and should not be regarded as absolutely correct.
