A device for registering the center of a framing supported electrical outlet box by an identation on a sheet of wall board when the latter is moved temporarily to the position it will permanently occupy when secured to said framing, said outlet box of the type that includes a back from which a pair of end walls and sidewalls extend forwardly to terminate in a pair of horizontal and vertical edges, said back, end walls and sidewalls cooperating to define a confined space, said device including: a. a horizontally positionable plate of less length than the width of said confined space and removably disposable in the latter; b. a pair of laterally spaced projections that extend forwardly from said plate; c. first and second pairs of legs slidably movable in first and second pairs of vertical openings in said pair of projections, said legs having first ends; d. first and second grippers supported from said first ends of said first and second pairs of legs; e. first springs means that tend to move said grippers away from one another into gripping contact with said pair of end walls; f. a prong that has a pointed forward end; g. first means between said pair of projections for slidably supporting said prong for movement normal to said plate; h. second means that tend to maintain said prong in a first position where said pointed end is disposed rearwardly of said pair of projections; and i. third means for moving said prong forwardly for said pointed end to form said indentation on said wall board as a guide to subsequently cut an opening in said wall board in alignment with said outlet box.
