HEAVY DUTY - Weather resistant Spider Cords have a tough, stabilized 5/16” nylon braid cord with a premium rubber core, non-scratch industrial strength hooks, and zinc plated steel carabiners for long life. The durable nylon braid is up to 10 times more abrasion-resistant than polypropene braid found on standard flat and round bungee cords to withstand the harshest applications..ADJUSTABLE - Spider Cords easily adjust from from 7” to 70” stretched. The hooks have an easy-grip finger hole for safer and secure handling under tension..FAST - No buckles, ratchets or loops. Simply slide the patented hook to the desired length and pull the bungee cord up to lock the hook into position. There is no need to release the hook to increase tension - just pull on the cord free end. Pull down on the cord to quickly release the hook for the next use..VERSATILE - Spider Cords have 1 ¼” wide opening hooks for maximum versatility and are designed to secure to a broad range of attachment points. The carabiner easily connects to tarpaulin eyelets and D-Rings on truck, trailer and general covers. Carabiners can be connected together to increase the cord length or attached quickly and securely to the hook, forming an adjustable loop. No need for assorted or different size bungee cords. Always the perfect length..TRUSTED - We stand behind our products. Don’t hesitate to contact us through Amazon if you have any questions.
