A square or right angle abutment contact surface, which is formed by a flat base which is attached to and projects laterally beyond spaced parallel surfaces of the rectangular body for engaging and contacting a structural member to be aligned. The circular level element is either permanently attached to the elongate body or removably attached, in which case it is movable between operative and inoperative positions which do not interfere with the proper placement of the structural member against the abutment contact combination device.
