20 PACK OF ELASTIC HOOKS: Included in our set are 20 bungee cord loops with black metal hooks on the end. The elastic cord is 8cm (3.14 inches) in length and the hook is 7cm (2.75 inches) in length. The total length of the cord and hook is 15cm (5.90 inches). The cord is 6mm thick and the hook is 3.8mm thick. The elastic cord can stretch to a maximum length of 25cm (9.84 inches). DURABLE MATERIALS USED: The bungee cord is made from rubber and is both flexible and can withstand heavy strain. The hook is made from iron and is waterproof. The hook features a rubber end so it is not sharp and will not pierce through fabric. Both the cord and the hook are weather proof and will not rust, fray or break. EASY TO USE DESIGN: Our elastic bungee cords can be affixed in seconds. Simply thread the loop through, for instance, the eyelet of the tent, pass the hook through the loop and pull tight. Add these to the end of a carabiner for a helpful camping necessity. You can even use these to secure luggage when travelling. Due to the loop design, you can attach them to a variety of different objects. MULTIFUNCTIONAL: Use these hooks to secure a net over a trailer. The hooks will ensure the net stays in place and the contents in your trailer will not come loose when travelling. Our hooks can also be used with tarpaulin material. Thread the hooks through the eyelets and secure the sheet on your vehicle such as a car, camper van, motorcycle or boat. These hooks are also great when it comes to camping. Secure your camp/canopy into ground anchors or use them to hold open your tent's entrance way.
