Which device is recommended to secure backbone cable in a vertical pathway during a pulling operation?

Using a wire mesh grip to secure backbone cable in a vertical pathway during a pulling operation is recommended due to its ability to provide even distribution of pressure around the cable, minimizing the risk of damage. Wire mesh grips are designed specifically for this purpose, allowing for a strong grip that can support the weight of the cable as it is pulled through conduits or vertical pathways. This is particularly important with larger or heavier backbone cables, as they often require reliable support to prevent bending or crushing during installation.

Other securing methods may not distribute the load as effectively, potentially leading to cable damage or failure. While zip ties, cable clamps, and plastic ties can be useful in certain applications, they may not offer the same level of security and protection during a pulling operation. They could lead to localized pressure points that might harm the cable or make it difficult to maintain the integrity of the installation process. As such, when dealing with the unique demands of backbone cable installation, wire mesh grips are the optimal choice.
