BoatBuckle Pro Series tie-downs feature the SUR-Grip Kwik-Lok buckle for maximum comfort. The Pro Series Bow Tie-Down has one-inch nylon webbing, a zinc-coated steel hook, and a loop end for easy attachment. It has a 1,200-pound break strength and 400 pounds safe working load. For maximum trailering safety, IMMI recommends that a bow tie-down always be used in conjunction with a winch strap and transom or gunwale tie-down. BoatBuckle brand tie-down systems offer professional fishermen and weekend boaters convenient, high quality tie-down systems so they can spend more time on the water and less time on the boat ramp. IMMI is the leading marine tie-down manufacturer in North America.
