Abstract: A combination leveling and marking tool for use in establishing wall support locations existing underneath a wall covering material such as dry wall or wall board material. The tool includes a central elongate extending portion having a first end and a second end and first and second elongate extending wing portions pivotally secured to the opposite ends of the central portion. The central portion and the wing portions each exhibit an opposing surface within which is defined individual pluralities of semi-circular shaped recesses. The wing portions establish a first folded position against the central portion and in which the pluralities of semi-circular recesses align to establish an extending row of circular apertures which are adapted to receive a mounting fastener in inserting fashion therethrough. The wing portions are further capable of being pivoted to a second unfolded position in which the wing portions are established in substantially perpendicular extending fashion relative to the central portion.
