Used to attach tarps or netting to pipe. Our ABS Snap Clamps have higher temperature resistance and gripping strength than our original clamps. They are compatible with many types of pipe, including PVC & EMT (metal conduit). Some applications include greenhouses, row covers, shelters, bird protection, dog beds, and quilting frames. In windy areas, the Grip Clamps can be used to hold the Snap Clamps more securely.
