Abstract
An enhanced apparatus and method for securing a wire to a pulling cable for pulling wire. Specifically, the pulling cable and wire are attached via a pulling head body. The wire is inserted into an end of the pulling head body and secured by crimping the pulling head body against the wire. Further, crimp zone indicators positioned on the outer surface of the pulling head body indicate the optimal zone of crimping to achieve substantial contact between the pulling head body and the wire. A pulling cable is secured to the pulling head body via a ball swage that comprises a tapped surface.
