The correct sizing of a wire mesh pulling grip is based entirely on the outer diameter of the cable you are pulling.

1. Measure the Cable: Use a precise measuring tool (like a caliper) to determine the exact outside diameter of your cable. Do not rely on nominal cable size; measure the actual diameter.

2. Match to Grip Range: Every professional pulling grip is specified with a diameter range (e.g., 25-35mm). You must select a grip whose range perfectly encompasses your measured cable diameter. A grip that is too large will not constrict properly and will slip. A grip that is too small will be impossible to install or will be over-stressed.

3. Consider the Application: For multi-conductor cables or for pulling multiple cables at once, you may need a specialized grip designed for that purpose. These grips will have a different sizing method, often based on the combined circumference of the conductors.

By correctly sizing your grip, you guarantee a secure connection to the cable, which is the foundation of a safe and successful pull.
