Tensile and abrasion resistance: Marine grade elastic tensioner has the advantage of strong waterproof and good wear resistance. Rubber Elastic Cord: Each rubber rope is composed of a polyester outer sheath and natural rubber cores. No matter what size you choose, the bungee cords have an elongation capacity of about 100%, meaning they can stretch to double their original length and offer fantastic impact resistance. But we do not recommend using it to the maximum for safety reasons. Versatile rope: The rubber rope is also suitable for camping, such as the installation of sleeping bags, camping mats, tarpaulins, banners, backpacks, rainwear, cargo nets, air mattresses and fishing equipment. High quality: With industrial grade strength and unique UV resistance design, they are not easy to deform or fade in the sun to extend the life of the product outdoors. Sufficient supply: an expandable 10 m cord for tarpaulin that offers sufficient length and strength to ensure safety when attaching and fastening.
