Automatic gripping jaws work just like the Right Angle Clamp, but the jaws are turned 90, making them just the ticket for face frame construction. No more three handed holding while working with pipe and bar clamps, the Face Frame Clamp allows you to work with just one joint at a time. And since it applies pressure in-line with the joint, glue slipping is also a thing of the past. Super strong construction for years of dependable service. For 3/4 stock.
