Apparatus for lifting and supporting wallboard or other sheet material for horizontal or vertical installation on a ceiling or side wall of a structure. A pair of spaced apart identical pivot arms attach at one end to studs, joists or the like available in a building under construction and the other ends are connected together by an elongated bar or rod member. A clip or hanger supports the sheet material when the apparatus is in a vertical position and when translated toward the attachment to vertical studs the arms lock in this horizontal position. The apparatus can be operated in right or left direction of pivot. The apparatus can be easily stored in a small space by removal of the interconnecting rod.
