Carr Lane CL-2-LCP-B-1 Locking Clamping Pin, Complete Assembly

Locking Clamping Pins are similar to standard Clamping Pins, except that the pin body is positively retained in a locking bushing. In fully retracted position, the bushing's spring clip snaps into the pin's radial groove. This holds the pin fully retracted by spring force and positively prevents removal. Spring pressure also holds the pin in intermediate extended positions, an advantage especially if the fixture is turned upside down.
