Description
Shock cord, also called stretch cord or bungee cord, has a natural rubber core under a diamond braided polyester cover. The core is natural rubber from Malaysia, made of many small rubber strands, which makes it stronger and more elastic than most other cords. The polyester cover resists sun and wear much better than nylon or polypropylene. It's a marine grade cord used for tarps, bungee cords, boats, camping and tie-downs. For ready-made straps with hooks, see Tarp Straps.
