Polyform F-4 Twin Eye Fender 8.5" x 40.5" - White - F-4-WHITE
Protect your vessel with industry-trusted marine cushioning from the Polyform F-4 Twin Eye Fender (8.5″ x 40.5″) in White — a high-performance fender engineered for boaters who demand durability, flexibility, and long-lasting protection. Whether you’re docking at a busy marina, securing to a piling, or trailering between destinations, this rugged fender delivers reliable impact resistance and abrasion protection for larger boats approximately 30′–35′ in length.
Crafted using Polyform’s signature one-piece molded vinyl construction with even wall thickness, the F-4 resists deformation and wear under pressure, ensuring consistent performance in harsh marine environments. The twin-eye design offers versatile mounting options — allowing you to hang the fender vertically or horizontally, based on boat configuration and docking conditions. Reinforced ropeholds and raised molded-in ribs increase abrasion resistance and keep dock lines secure, while the dependable Polyform valve makes inflation and deflation quick and reliable.
With its sleek white finish, the F-4 Fender blends function with style, providing a professional look that complements your boat’s appearance while offering industry-leading protection. Ideal for sailboats, cruisers, and larger recreational vessels, this fender is a trusted choice for both new boat owners and seasoned mariners.
