Abstract: A clamping system is disclosed for use with an assembly jig. It features a clamp having one jaw consisting of a pin and the other jaw including a pad which when closed will be spaced from but parallel to the pin. The pin is to be inserted into a circular locating device which is joined to the frame of the assembly jig. Due to the circular nature of the locator and use of the pin, the workpiece can be grasped in an over-center locking position in almost any orientation. The clamping device together with the assembly jig provides standardized pieces that can be used for limited production items that need to be held upon a jig relationship when locked.
