Abstract: A clamping apparatus is disclosed which can clamp a workpiece in two non-parallel directions. The apparatus is made up of a pipe clamp having an attached adjustable height beam member which spans a significant portion of the pipe clamp's length. The beam member is attached to the pipe clamp by a "U"-bolt shaped retainer at one end and an eye-bolt shaped retainer at the other end. The beam member is sized so that it can be released from the "U"-bolt shaped retainer and thereby be allowed to pivot about the eye-bolt shaped retainer. A modified block structure is also disclosed which can be placed between the beam member and a workpiece being clamped.
