Assemble, fasten, and glue parts with TEKTON Nylon Spring Clamps. Quick, versatile, and lightweight, they're easy to attach, release, and reposition, making them ideal for temporarily securing plastic sheeting, tarps, covers, fabric, and photography backdrops. The impact-modified nylon construction is reinforced with fiberglass for extra strength. Wide pivoting jaw pads self-adjust to uneven surfaces, offering a sure, uniform grip. Secondary interior jaws are curved with serrated teeth to clamp around pipes, poles, and railings. Consistent clamping pressure is generated by a tempered steel coil spring that resists fatigue.
