ABSTRACT:
A guide body having angularly related support surfaces applied to substantially parallel surfaces of a workpiece, supports a pair of pressure distributing jaw elements connected by pin and slot connectors to a handle operated actuating linkage. A plurality of work engaging pins projecting from the pressure pads associated with the jaw elements resist slidable displacement thereof along the work surface as normal clamping pressure is exerted through the pads. The pads are angularly adjusted to the work surfaces to relieve high concentrations of clamping pressure.
