ABSTRACT:
An adjustable jig for elevating plasterboard. The jig comprises a frame for supporting a rack which holds the plasterboard. Three telescopic members are supported by the frame and are individually adjustable to elevate the rack at a desired angular relation to fit uneven or angled ceilings. One of the telescopic members is provided with a hinged toggle operator whereby one side of the rack may be substantially lowered from the other side of the rack for easy loading of the plasterboard or for performing work upon the plasterboard before it is elevated. The toggle operator is easily moveable from a collapsed to an erect position to move the rack toward a lift position where the telescopic members may be adjusted by a workman as desired. The support frame has a base supporting the telescopic members and may be easily moved along a floor to any desired work position. The rack when not in use for lifting plasterboard may be installed in a vertical position from the frame and may be used as a standard to support a basketball backboard, signs or the like.
