the locator support now firmly mounted to the utility box the sheet of wallboard 22 is pressed to the studs and in doing so is punctured by the projections 35 and 36 a worker on the side of the wallboard distal the utility box now sees the two projections projecting from the wallboard the worker may now readily place the template 26 flush against the wallboard 26 with projection 36 passing through template aperture 40 and projection 35 passing through aperture 42 again correct orientation is insured by the fact that the upper aperture is sized only to receive the smaller projection 35 which can differ depending upon which side of the stud the box is mounted arrow 44 also indicates proper template orientation the worker may now take a writing instrument and draw a line about the perimeter of the template then remove the template and finally cut an opening in the wallboard along the mark with a standard cutting tool and remove a rectilinear section of wallboard from the main body thereby revealing the presence of the utility box located therebehind in marking the rectangular mark about the perimeter the writing instrument typically forms a mark at a slight distance away from the edge of the template itself whereupon the cutting instrument will itself in following the mark pass slightly about the utility.
