ABSTRACT:
An electric lead insertion device for feeding an electrical wire under carpeting or the like, the device including a blunt-nosed member having a toboggan-shaped cross section, the electrical lead having one end thereof secured to the member which is then inserted under one end of a carpet. A pointed metal probe is inserted through the carpet into contact with the member to displace the member under the carpet a distance determined by the length of the probe. The member location is manually noted, the probe reinserted and the member displaced an additional distance. The probe is provided with a pivotable handle containing an indicating lamp and a battery source which can be electrically connected to the other end of the electrical lead. With the probe and the member made of electrically conductive material a circuit is completed with the probe contacting the member to indicate its location.
