The patented Midi is a ideal product designed specifically to grip tarps, clear poly or any fabric or sheet goods that require a strong long-lasting hold. Larger and stronger than the mini clip. The Midi clip is designed for heavier-duty applications where additional clamping strength is required. Often called tarp clips, tarp fasteners or tarp clamps, the entire line up of EasyKlip® products has been engineered to be durable, affordable and easy to use. All it takes is one hand. The patented EasyKlip® wedge design is up to five times as strong as other tarp clips and it actually grips tighter the more it is pulled on. Competitor's tarp clips grip the material using constant static pressure, no matter how heavy or how much the load weighs or pulls. The Midi clip has been engineered to increase its clamping pressure or grip, as the load increases. This makes our tarp clips the strongest most reliable on the market.
