ABSTRACT:
A clamping attachment for a jack including two pivoting jaws secured to a frame by means of pivot pins. The pivoting jaws include portions which are contacted by a load inserted between the jaw faces whereby the load causes the jaws to pivot, thereby clamping the load between the jaw faces. The jaws are reversible for adjusting the space between the jaw faces. The jaws may also be fixedly pinned to the frame without pivoting movement. The jaws may be mounted at various positions on the frame to adjust the distance between the jaw faces.
