ABSTRACT:
A housing mounts a continuous side wall formed with a cutting edge arranged in a single plane, with the housing including a top wall, with a projecting flange extending upwardly of the top wall in an orthogonal relationship, and an upper distal end of the flange including an impact plate fixedly mounted thereto. In this manner, impact of the plate effects projection of the cutting edge into a sheetrock member to define a rectilinear cut for mounting of an electrical socket tool therewithin.
