First introduced in 1982, the Dan-Fender Heavy-Duty buoy fender is built to protect your boat in all weather conditions. Made from a strong, flexible material, this boat fender features a patented design and a solid rope hold for added strength and durability.
The uniquely designed rope hold incorporates a special valve system, making inflation straightforward while helping to prevent air leaks.
