What wire size are you pulling? If you’re pulling aluminum conductor steel reinforced (ACSR) cable you may want to use a different wire grip than if you’re pulling extra-high-strength cable (EHSC).
When pulling wire, it is critical that the wire grips are properly sized to avoid slippage and safely maintain temporary tension until the wire or cable can be permanently terminated.
It is important that you choose the right wire grip for your rated working load capacity. You will not need a wire grip rated for 20,000 lbs. if the maximum working load is 4,500 lbs. However, you must ensure the grip can handle the maximum load you’ll be pulling.
Use the specifications you selected in steps one through three to select the grip you need. When choosing your grip, you may want to consider these factors as well:

Here is a step-by-step guide on what to determine before making your order. On top of that, here are some handy tips to keep in mind during the selection process.
Cable Pulling Grip Types
The two most commonly used cable pulling grip types are set screw grips and wire mesh grips.
Set screw grips use two or more of its opposing screws to provide positive locking. These types of grips are more flexible in terms of the size and number of cables being pulled, as they can even accommodate pulls of up to four cables by using individual locking heads.

Wire-mesh grips rely on many points of mechanical gripping through each cross section in the wire grip, making it very dependable.
Single Weave, Double Weave or Multi-Weave Wire Mesh Grips
Determining the size of the cable being pulled will also help you choose the right grip design among single weave, double weave, and multi weave wire mesh grips.
Single weave wire mesh grips are often used by electricians with smaller operations such as connecting insulated wire bundles to pulling tape or pulling wire rope through conduits.
Double weave mesh grips are designed for added mesh contact and have greater strength than single weave wire mesh grips. For this reason, they can handle longer and heavier pulling jobs such as the installation of underground cables and communication lines.
Multi weave grips are designed for pulling aluminium or copper bare conductors, insulated cables, and wire rope. These grips are ideal for distribution line stringing and overhead transmissions.
Pulling Eye
The pulling eye, commonly attached to the top of the puling grip, can either be a rotating, flexible, or breakaway type. If the cable has to go through a lot of bends in the conduit, a swivel eye type is best to avoid cables from getting tangled.
The flexible eye type is less rigid and follows the line of the pull around corners and bends. It is seen most commonly in single weave cable pulling grip types for light pulling jobs as it allows for easy attachment to a pulling line. The breakaway eye type, on one hand, functions as a swivel eye but will break if the tension is too great.
You will need to carefully consider the above factors before purchasing the right cable pulling grip for your applications.
