T-H Marine Rod Tamer straps are the best design and highest quality of any rod holding device on the market. These straps are molded of black polyurethane material that will retain its stretch and remain unaffected by sunlight and most chemicals. Unlike the old hook-and-loop straps, they will not get hung up in fish hooks, they will not lose their hold when wet, and they will not fade out. The straps stretch over rods and hook into a loop mounted on the deck.The strap end mounts to the deck with one countersunk screw. This model is perfect for aluminum or foam-filled fiberglass boats that cannot accept the retracting gunwale mount version.
