ABSTRACT:
A clamp suitable for a wide variety of uses is provided. The clamp is particularly suitable for selectively either rotating a variety of standard structural workpieces so that they rest on a new base after a lift, or lifting workpieces so that they rest on their original base after a lift. The invention includes a swivel pad having at least two faces and a settable jaw for retaining workpieces. A selection of one face to engage a workpiece will cause it to rest on a new base after a lift, and the selection of another will cause the workpiece to rest on its original base after a lift.
