Pulling Grip Selection Guide
How to select correct pulling grip:
1. Select the type of grip needed.
2. Select the size of grip needed (see below).
3. Select a grip with maximum rated capacity that meets or exceeds the cable puller’s maximum pulling force.
2. Select the size of grip needed.
After determining the type of grip needed, measure the diameter of the cable
being pulled. If pulling more than one cable “of the same diameter,” refer to
chart below for required grip diameter range. If pulling more than one cable
“of different diameters,” bundle cables together, measure the circumference
and refer to the chart on bottom of this page for required grip diameter range.
Once the cable diameter or ­required grip diameter is determined, refer to
individual chart for type of grip chosen to locate Catalog/UPC number.

* Split grips require the next larger size.
NOTE:
Rope is a very critical link in the cable pulling system. See page 207 for proper pulling rope selection.
