The clamp also comes with adjustable aluminum cold shoes which offer not only different size holders for flash lights, but also a more long-lasting operation than plastic ones. It's easy and convenient to attach the clamp to a plank or tube from 5-40mm with the strong spring steel equipped inside the clamp. The 16mm stud with 3/8” thread hole and the sockets attached with the clamp can be connected with light stands and an umbrella.
