ABSTRACT:
A flexible feeder tube with a weakened longitudinal side wall is coupled at one end by a nozzle with an underground conduit while the remaining end of the feeder tube is located aboveground and joined with a lubricating collar that is split. A supply of cable has a plain end and an end equipped with connectors joined to the conductors of the cable. The plain end of the cable is joined with a pull-line that is fed from the conduit through the flexible feeder tube. The plain end of the cable is then drawn into the feeder tube while lubricant is applied to the sheathing of the cable. Pulling of the cable through the conduit is terminated before the end with the connector members contacts the feeder tube. The lubricating collar is split and held together by fasteners which are loosened so that the collar can be removed from the cable and then the feeder tube is removed from the cable by severing the feeder tube along the weakened longitudinal side wall. The feeder tube is light weight and removed laterally from the cable by the passage of the cable through the severed side wall of the feeder tube. After the feeder tube is stripped from the cable, it is discarded and the cable is then positioned so that the connector members on the trailing end are moved into a desired location relative to the conduit.
