Abstract:
Disclosed is a system comprising an apparatus and method to aid electricians or other workers desiring to pass a wire, cord, or other such material through an inaccessible area inside a wall, above a ceiling, or below a floor of a residential home or commercial building. The apparatus consists of two elastic poles with the first pole containing a magnet at its distal end and the second pole containing a void space along its longitudinal axis wherein a string of a length substantially longer than the length of the second pole is passed through the string having a magnet at one end so when fully passed through the magnet is at the distal end of the second pole. The method comprises the steps of passing the first pole through a first opening cut into the wall, ceiling, or floor; passing the second pole through a second opening cut into the wall, ceiling, or floor; manipulating first and second poles such that the magnets on their distal ends magnetically bond with each other; withdrawing first pole from first opening so that the string defines a path between the openings where a wire may be drawn through.
