"Manufactured from dense polyester web, this Ratchet Tie-Down Strap has the same 3,300 lb. working load limit of nylon, but is thinner, won't stretch as much, and will stand up better to moisture and acid. Featuring two high-quality Double J Hooks, this 2"" wide strap is perfect for securing loads on auto haulers. Web assemblies should be stored in a cool, dry, dark place and cleaned with plain water only, never machine washed."
