The ProMaster Large Clip Clamp is a convenient tool for mounting all kinds of stuff in all sorts of places. The large, powerful jaws hold tight against the bars of light stands, booms, and backdrop crossbars, as well as table edges, tripod legs, tree branches, park benches, lampposts, and more. Soft pads on the jaws aid in clamping and reduce the chances of scratching surfaces. The Clip Clamp has both a ? receiver and a stud with ?-16 threads inside, so it can connect to a variety of lights, modifiers, props, and other important items.
