Abstract
A method and apparatus or tool for pulling wire through a wall or panel formed by spaced apart vertical studs, a plate at one end of said studs, and opposed wall panels mounted on said studs. An opening is cut through one of the wall panels between the studs and a hole is drilled in the plate using a long, flexible drill bit. A wire stringing tool formed by an elongated stiffly flexible rod at least partially covered with an elongated, flexible, expandable and contractible woven sleeve is inserted through the opening between the panels and through the drilled hole. The rod and sleeve is slightly retracted to form a loop in the sleeve at the inserted end of the sleeve-covered rod. The loop in the sleeve is hooked with an elongated hooking rod and the sleeve is pulled through the hole to position its other cut end at a point remote therefrom. A wire is inserted into and gripped by the sleeve by applying tension to the sleeve, and the wire is pulled through the hole and opening to string the wire between the remote point and the wall or panel opening.
