Polyform HTM-4 Fender 13.5" x 34.8" - Black w/Adapter - HTM-4-BLACK

Protect your boat with reliable, heavy-duty docking and mooring protection thanks to the Polyform HTM-4 Fender 13.5″ x 34.8″ – Black with Adapter. Designed for medium-duty applications on larger vessels, this high-performance marine fender from Polyform’s HTM (Hole-Through-Middle) Series offers versatile, robust protection against impacts with docks, pilings, and neighboring boats. The classic “hole-through-middle” design allows you to hang the fender vertically or horizontally based on your docking setup and cleat placement, giving you installation flexibility without sacrificing performance. 

Constructed with even wall thickness and molded-in ribs, the HTM-4 Fender delivers strength and abrasion resistance where it matters most. Reinforced tube ends help prevent lines from pulling through under tension, while the unique Polyform valve ensures secure air retention and easy inflation or deflation. The included inflation adapter means you’re ready to set up right out of the box. With its sleek black finish, this fender not only protects but also complements your vessel’s appearance. Designed for boats in the 40′–50′ (12.2 – 15.2 m) range, it’s a go-to choice for cruisers, sailboats, and larger recreational craft.
