Abstract: A tool for driving electrical staples and the like, to support nonmetallic wiring, which prevents the staple from clamping the cable and possibly damaging the insulation. The tool comprises a body portion which has a recessed passage formed at one end of its longitudinal axis. The recessed passage is shaped and sized to receive an electrical staple and completely surround a typical electrical conductor without touching it. The recessed passage also incorporates a staple-engaging member and a magnet to secure a staple within the recessed passage of the tool while the staple is being hammered into a building structure.
