Abstract: An installed electrical conduit is formed from a plurality of lengths of hollow conduit which are joined together by installing a plurality of conduit couplings having removably covered access ports spaced along the installed conduit through which the insulated electrical wires are to be pulled. The covered access ports are opened and lubricant is injected through these access ports at spaced intervals along the installed conduit. The electrical wiring is pulled through the lubricated conduit. The open access ports also allow the observance of the progress of the wire pulling; after the pulling operation is completed the access ports are closed. The ported couplings are preferably located in front of bends with respect to the intended direction of pulling to thereby provide lubricating points preceeding the bends around which the wires are to be pulled to facilitate the pulling operation.
