[Note: The sliding buckle cannot adjust the length of the elastic band.] You can drag the slider to determine the bifurcation point or the position of the rubber band, which can accommodate different shape items better, but cannot adjust the length of the rubber band. [Design 4-prong ] Each elastic band is made up of 4 small straps, and you can set the spacing of 4 small straps to better cover the object. And the four prongs can exert pressure on objects in multiple directions. [Protective Effects] The surface of the hardened steel hook is wrapped with a thick plastic shell, which can protect your vehicle from scratches . [Rubber + Nylon] The elastic band is made of high quality rubber and wrapped in nylon fabric. Good elasticity, good flexibility, not easy to deform and break. [Easy to carry ] For daily life or long-distance travel, you can attach the luggage straps directly to the vehicle. It can also be packed in a backpack without taking up too much space.
