Cable Pulling Principles (cont'd)
Cable Pulling Forces (cont'd)
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.

When selecting a pulling grip, it is extremely important
to select a grip of the correct (1) type, (2) size, and (3)
maximum rated capacity.
1. Select the correct type based on the descriptions
of each type in the Greenlee catalog.
2. Measure the circumference of the wire bundle.
(To do this accurately, fasten a tie strap around the
bundle. Cut off and discard the tail. Then cut the tie
strap and measure its length.). Use the table pro-
vided to find the correct size.
3. See the maximum rated capacities in the Greenlee
catalog.
