At the Connectors

The connectors will be subjected to the cable puller's
maximum pulling force.
Several types of rope connectors—clevises, swivels,
and rope-to-swivel connectors—are available. Follow
the instructions provided with each to provide a good
connection.
Two types of wire connectors—wire grips and pulling
grips—are available. The wire grip uses a set screw
to clamp onto the conductors of the cable. The pulling
grip consists of a wire mesh basket that slides over
the cable and grips the insulation.
