The CL-C35 is a powerful spring clamp and is indispensable in the studio. You can use it to prevent the unwinding of background rolls, the hanging of cloths or the clamping of tools. The finish of the clamp is made of rubber to prevent damage. The clamp can be used for objects with a thickness of 40 millimeters. At the top of the clamp are 2 holes where a spigot adapter (1/4 ") can be turned.
