When you need heavy duty tie downs to secure your flatbed tarp or cargo on your flatbed trailer, US Cargo Control's 21" rubber tarp straps with hooks will do the job well. Comes in a 50 pack so you have plenty of straps for your securement needs. Rubber bungee straps are excellent to use for many flatbed tie down applications, but you can also use these for securing canvas tarps or other tarp types as well as for camping, pickup trucks, recreational vehicles, motorcycles, boats, vans, and RVs/campers. Can be used for both indoor and outdoor use. The rubber tie downs are 21 inches long and can stretch up to 32 inches. They're made of industrial grade natural rubber, holding up well in the toughest weather conditions. Not only do they perform well in many weather conditions, but the bungees with hooks are waterproof and will handle well in colder, northern climates. When faced in extremely cold temperatures, the straps will not become brittle, crack, or tear in freezing temperatures. It'll have more stretch and snap back more readily to its original state than EPDM. The heavy duty bungee cords with hooks have attached 2" crimped S-hooks to each end, allowing the tie downs to secure easily to anything. The crimped style helps the S-hooks stay snug around the rubber to reduce slipping, and helps the hook from getting caught and ripping your tarp. The next time you need to secure your tarp, cargo, or items with heavy duty tie down straps, look into US Cargo Control's Black Rubber Bungee Cords with S-Hooks.
