Whether it is pulling cables through a conduit or stringing them over utility lines, installers usually encounter common problems of how to get the cable to its final destination without causing damage to it. To fix this issue, installers greatly rely on the use of a cable pulling grip. Its primary purpose is to provide users a secure hold of the cable as it is removed or installed into a conduit or duct. These pulling grips are often made of stainless steel or galvanized steel. In order to achieve a secure grip, the type of application and the specifications of the cable run must be determined first.
Moreover, if the purpose is to pull through conduits, it’s imperative to know if there are many bends involved. Also, do determine if the cable will be run indoors or outdoors and whether it is copper or fiber-optic. Knowing these factors will help installers to choose and use the right cable pulling grip that is designed and durable enough for the job. Using a grip that is too weak can pop off the cable and interrupt the pull, making it harder for the installer to complete the job.
Pulling grips come in different varieties but the most common ones are the set-screw and wire-mesh. They have the same objective but each cable pulling grip works differently. The set screw grips are usually used for long pulls of heavy copper cables through opposing screws. This provides a positive lock on each cable, allowing four cables to be pulled at once. Conversely, the wire-mesh grips rely on two or more points to hold the cable. They use different action grips depending on several points of mechanical gripping. They are highly reliable when pulling cables in outside-plant applications such as on overhead power lines with stringing wires.
