What Is a Pulling Grip?
A pulling grip is a specialized tool that helps you install or remove cables safely and efficiently. Think of it as a strong, flexible mesh sleeve that wraps around a cable, much like how a finger trap grips your finger.
When you pull on the grip, it tightens around the cable, holding it securely without causing damage. This tool ensures you can guide cables through conduits, ducts, or overhead spaces with control and confidence.
How Pulling Grips Work?
You rely on a pulling grip to hold cables firmly during installation. The design uses a mesh pattern that tightens as you pull, distributing force evenly along the cable. This prevents stress points and reduces the risk of cable damage.
Many grips feature swivel or flexible eyes, which help you navigate bends and prevent twisting. Some models include breakaway eyes that release tension if you exceed safe limits. Engineers select materials and weave patterns to maximize strength, flexibility, and durability.
The grip’s structure spreads the load, so you avoid stress concentrations that could harm the cable.
The main functions and design features include:
Securely holding cables during pulls or removals
Adapting to different cable types and installation scenarios
Using features like swivel eyes, flexible eyes, and breakaway eyes for safety and versatility

Attaching the Pulling Grip
You attach the pulling grip to your wire by sliding the mesh sleeve over the cable end. Make sure the grip covers enough length to hold the wire securely. Powerful Machinery’s Pulling Grip features a flexible mesh and a loop for easy attachment to your pulling equipment. Avoid attaching the grip to damaged sections of wire.
When you attach the grip, pay attention to tension limits. Exceeding recommended tension can damage your wire. Use the following table to determine the maximum pulling tension for different conductor types:
Conductor Type | CTC Value | Maximum Pulling Tension Formula |
|---|---|---|
Copper conductor with aluminum compression eyes | 0.011 | Tmax = CTC x CA x N |
Aluminum stranded conductor with aluminum compression eyes | 0.008 | Tmax = CTC x CA x N |
Aluminum solid conductor with aluminum compression eyes | 0.006 | Tmax = CTC x CA x N |
Copper conductor with filled eyes | 0.013 | Tmax = CTC x CA x N |
Aluminum stranded conductor with filled eyes | 0.011 | Tmax = CTC x CA x N |
Aluminum solid conductor with filled eyes | 0.008 | Tmax = CTC x CA x N |
You calculate the maximum allowable tension using the formula above. For most cable grips, do not exceed 1,000 lbs of pulling force. Powerful Machinery’s grips are engineered to distribute force evenly, reducing the risk of slippage or damage.
Note: Always attach the grip to the strength members of the wire, not the jacket, to prevent stretching or breaking.
Pulling Technique
