While rewiring my house, I was confronted several times with having to thread the cable behind finished walls and under subfloors. Difficulty arose when the cable had to be drawn through holes that were perpendicular to the only direction I could pull the cable.
To keep the cable from binding against the edges of the hole, I fabricated the contraption shown here. It’s a 16-in. piece of 3/8-in. steel rod. At one end is a plastic spool that once held monofilament fishing line. A cotter pin holds the spool in place. Used as a pulley, the spool makes it easy to pull cable through a hole that’s at right angles to the direction of pull.
