Abstract
An attachment system for a cable puller provides for securing the cable puller to various sized conduits. The attachment system includes a clamping assembly having pivotable arms angled to generally be formed in V-shapes at the ends which engage and trap the conduit at four separate points. The clamping arms have gripping members that radially nest against the conduit threads and an overhang portion which acts as a location stop for the conduit. Each clamping arm has a face which extends past the pivot point. A screw and a nut between the extended portion of the clamping arms act on a push block which in turn acts against the arm faces such that when the nut is screwed inward, it causes the gripping members to be forced against the conduit in order to secure the conduit in place.
