Answer from Ningbo Changshi: Correct sizing is the most critical factor in ensuring a safe and effective cable pull. A grip that is too large won't hold the cable securely, while one that is too small may not fit or could be overstressed.

The proper sizing is based on the outside diameter (OD) of the cable or conductor. Our single-eye cable pulling socks are manufactured with a specific diameter range, for example, 30mm-40mm or 50mm-60mm. To ensure a secure grip, the cable's OD must fall within this specified range. If you are pulling multiple cables with a single grip, you must bundle them together and measure the combined circumference, then convert that measurement back to a diameter to find the correct sock size. We provide detailed sizing charts to assist our clients in selecting the perfect fit for their specific project needs.
