Made with industrial grade natural rubber and featuring crimped S-hook ends, these versatile tarp straps are designed to work with the US Cargo Control steel and lumber tarps. Sold in packs of 50, the natural rubber has excellent resistance to harsh weather, and will not lose elasticity or turn brittle after constant exposure to the elements. These versatile tie-down straps are ideal for securing tarps as well as cargo on trailers, trucks, and campers.
