ABSTRACT:
A tool and method for installing electrical cable into an elongated tubular conduit by pushing the cable through the conduit. The tool includes a nose piece having a rounded forward distal end, a tail piece also having a rounded forward end and a semi-flexible slender intermediate member connected therebetween. At rest, the tool is preferably straight and cylindrical. In use, the tail piece is threadably engaged onto a lead end of the cable to be installed and then pushed into the conduit. Continuing to push the cable into the conduit, the nosepiece guides the tool past any irregularities on the interior surface of the conduit and around conduit bends, facilitated by the flexing of the intermediate member.
