ABSTRACT:
A cable tensioning device comprises tubular shaft having an outer threaded portion, and a handle member surrounding a portion of the shaft, with the shaft and handle member being connected in screw-threaded relation. The shaft moves longitudinally relative to the handle as the handle rotates, driven by the screw threaded connection. A gripping member is carried on the shaft distal to the handle member for holding a replaceable bit, which, in turn, may carry a cable crimp. A cable lock is positioned typically proximal of the handle member to hold the ends of cables extending through the tubular shaft. Rotation of the handle member can cause the shaft to move longitudinally to lengthen the distance between the cable lock and a crimp held by a bit which, in turn, is held by the gripping member, to impose a tension on the cable. A meter is present for measuring the amount of tension applied to the cable.
