Polyform HTM-4 Fender 13.5" x 34.8" - Black

The Polyform HTM-4 Fender 13.5" x 34.8" in Black is a hole-through-mooring marine fender engineered for boats that demand serious dock and vessel protection. Built by Polyform U.S.—a name trusted across commercial and recreational boating for over five decades—this fender delivers reliable absorption of impact forces during docking, rafting, and anchoring operations.

Constructed from high-density polyurethane foam with a reinforced rubber skin, the HTM-4 resists UV degradation, saltwater corrosion, and abrasion from pilings, cleats, and rough dock surfaces. The hole-through design—indicated by the HTM designation—allows secure mounting via rope or chain passed directly through the fender's core, eliminating the need for external bridles while distributing load stress evenly across the entire structure.

At 13.5 inches in diameter and 34.8 inches in length, this cylindrical fender provides substantial contact surface area to disperse impact energy, while its 10.4-pound weight remains manageable for crews installing or repositioning gear. This fender works best on boats between 30 and 50 feet in length, where side-mounted or bow/stern protection is required.
