Abstract: An apparatus for temporarily hanging relatively heavy loads to be mounted upon a generally vertical wall surface to facilitate vertical and horizontal alignment and placement prior to permanent installation.The apparatus includes an elongate mounting strip (32) which may be horizontally attached to a wall surface, said mounting strip having a plurality of slits (46) fashioned inwardly along an edge thereof and thereby form a plurality of tab members (48) across said edge. At least some of the tabs may be operably inclined outwardly from said generally flat mounting strip (32) such that a cabinet may engage the tabs and thereby hang from the elongate mounting strip in a plumb posture for lateral positioning prior to permanent mounting upon the wall surface.
