ABSTRACT:
A string puller for drawing electrical wires through conduits consists of a 3/8 inch rod with a short 1/4 inch extension at one end. A washer is loosely held between the rod and extension. The rod is placed in the chuck of an electric drill and the short extension is fitted into one of the holes found in an electrical junction box. The invention is used to pull in a string coming into the box through the conduit: the other end of the string, at the other end of the conduit, is tied to the wire which is to be pulled through the conduit. The dirll is turned to pull in the string, thus dragging the wire through the conduit. The washer keeps the string from jumping into the extension and jamming. The rod may be of various lengths between 6 and 14 inches.
