Polyform HTM-4 Fender 13.5" x 34.8" - White w/Adapter - HTM-4-WHITE

Protect your vessel with the Polyform HTM-4 Fender 13.5″ x 34.8″ in White with Adapter, a rugged and versatile marine bumper designed to deliver dependable dockside and mooring protection for larger boats. Part of Polyform’s HTM (Hole-Through-Middle) Series, this high-performance fender combines robust construction with thoughtful design features that help cushion your boat against impacts with docks, pilings, and other vessels. 

Constructed with even wall thickness and vertical molded-in ribs, the HTM-4 fender provides enhanced strength, abrasion resistance, and durability in both protected and unprotected marine environments. Reinforced tube ends prevent lines from pulling through, while the unique Polyform valve system ensures secure inflation and long-lasting air retention. The “hole-through-middle” design offers flexible hanging options—hang it vertically or horizontally depending on your cleat layout or docking configuration. 

This model includes an inflation adapter for easy setup right out of the box, and its classic white finish blends seamlessly with most hull colors. Ideal for boats in the 40′–50′ (12.2 – 15.2 m) range, the HTM-4 Fender is engineered to give boat owners durable, reliable performance season after season.
