The EasyKlip grip clips are easy clips to use when you need a quick-release fastener for a grommet-free surface: as tarp clips, or on a canopy, banner, car or motorcycle cover, and other plastics and fabrics that are up to1/4" thick. Made from a glass-reinforced nylon, EasyKlips are uniquely engineered with a Wedge-Lock design that increases the pressure of the clip's clamp action when load weight increases. One clip will hold up to 220 lbs.
