ABSTRACT:
An apparatus fish's telecommunication or electrical wiring, optical cables or conduit behind walls without need for a plurality of drilled holes or cutting slots. The apparatus has a central drive shaft comprising a magnetic mouse; a string; and a permanent magnet. The magnetic mouse comprises a sheet cut from a soft magnetic sheet material, coated with a low friction surface finish. It is attached to the string and dropped through a first hole location in the wall into a common bay between joists behind the wall. Following insertion, the magnetic mouse is driven from the first hole location to a second hole location by a permanent magnet, which is translated over the ceiling or interior of the wall. Translation of the permanent magnet moves the magnetic mouse inside the ceiling or wall, carrying the string through the common bay from said second hole location to said first hole location, thereby establishing a fishing line. The permanent magnet is, optionally, covered with felt to prevent scratching of the wall. A telecommunication or electrical wire; or optical cable; or conduit is attached to said fishing line, causing it to be pulled through the common bay from said second hole location to said first hole location.
