A material handling apparatus includes a first support member (46), for supportively carrying a pair of opposed jaw members (32, 34), and a second support member (32) which is slidably attached to the first support member, for linear movement with respect thereto. The second support member has at least one slot (82, 84) formed therein. The apparatus also includes a pair of opposed jaws, which cooperate to define a workpiece-holding space therebetween. The jaws are pivotally attached to one another and to the first support member. Each of the jaws has a hinge portion (38, 40) and an extension (35, 37) opposite the hinge portion. The extension may be made detachable from the hinge portion. The hinge portion of each jaw has an inner portion and an outer portion, with the hinge portions closely aligned with each other. Each of the jaws also has a support post connected to the respective outer portion thereof, and the support posts fit slidably in the slot of the second support member. A spring (48) is also provided for biasing the second support member in a selected direction, whereby movement of the second support member, in a direction opposite the force of the spring, causes movement of the jaws.
