ABSTRACT:
A tool for pulling a cable through a hole in a wall where the wall thickness is much greater than the diameter of the hole and where the wall may be filled with insulating materials, the tool having a long slender stem with a tapered shorter sleeve surrounding it, the sleeve having a bore which is a sliding fit on the stem and having a larger bore sized to snuggly receive the cable, and the tool having cable grasping fingers fixed to the end of the rod with hooked ends which are driven into the cable when the sleeve is pulled over the fingers and the end of the cable, the larger bore of the sleeve being longer than the fingers so as to completely cover them and cover a significant length of cable.
