ABSTRACT:
A leader member is attached at one end to a lead end of the cable on its storage reel and at its other end to a cable pulling rope. The leader member is formed from a number of flexibly connected segments. Weights are attached to the leader member to counteract the tendency of the cable to twist or rotate as it is being strung. The segments of the leader member and the weights are shaped so that they pass readily over cable stringing blocks or pulleys. The weights are located on the leader member so that only one of them at a time can be engaged and disabled by a stringing block or pulley.
