ABSTRACT:
A work support device with adjustable length legs used to stabilize the work support on an uneven bearing surface, that is height adjustable, allowing the user to raise a supported work piece to a desired height, and that is levelable in that the user can adjust the work support to level the work piece being supported. Both the adjustable length legs and the height adjustable upper beam are self locking. Unlocking the height adjustable upper beam to allow downward movement is accomplished with finger pressure on a rod. Unlocking the adjustable length leg is accomplished with finger pressure on a lever. The self locking action occurs immediately upon releasing pressure on either the rod or the lever.
