Fish tape pulling grips are commonly used by electricians to help pull wires through conduits or cable trays. They provide a secure and efficient way to maneuver the tape and prevent it from slipping. However, there has been some concern regarding whether using fish tape pulling grips could potentially damage the wire coating. In this article, we will explore the possible risks and precautions that can be taken to minimize any potential damage.
Understanding Fish Tape Pulling Grips:
Fish tape pulling grips come in various shapes and sizes, but their primary purpose is to provide a firm grip on the fish tape. Most grips are made from durable materials such as steel or nylon, which offer strength and flexibility. These grips typically have teeth or serrated edges that grip onto the fish tape to prevent it from slipping out of one’s hand.
The Potential Risk of Wire Coating Damage:
While fish tape pulling grips are designed to securely hold the tape, there is a possibility that they could cause damage to the wire coating during the pulling process. The risk arises from factors such as excessive pressure, sharp edges, or abrasive materials.
Excessive Pressure: If too much force is applied to the fish tape while using a pulling grip, it could potentially dig into the wire coating and cause scraping or tearing. This is particularly true for older or more brittle wires that may be more susceptible to damage.
Sharp Edges: Some fish tape pulling grips may have sharp edges or rough surfaces. These sharp edges can scratch or abrade the wire coating, resulting in potential damage. It is important to choose a pulling grip that has smooth edges to minimize this risk.
Abrasive Materials: Certain materials used to make fish tape pulling grips, especially those made from steel, can be abrasive and cause friction against the wire coating. Over time, this friction can wear down the protective layer of the wire, leaving it vulnerable to damage.
Precautions to Minimize Wire Coating Damage:
Fortunately, there are several precautions that can be taken to minimize the risk of wire coating damage while using fish tape pulling grips.
Choosing the Right Grip: It is essential to select a fish tape pulling grip that is specifically designed to protect the wire coating. Grips made from non-abrasive materials, such as nylon, are generally recommended as they provide a secure grip without causing damage.
Inspecting the Grip: Before using a pulling grip, it is important to inspect it for any sharp edges or rough surfaces that could potentially damage the wire coating. If any defects are found, the grip should be replaced or filed down to ensure its safety.
Applying Moderate Pressure: When pulling the fish tape, it is crucial to apply only the necessary amount of pressure to avoid excessive force that can lead to wire coating damage. Using controlled and steady force can help prevent scraping or tearing of the wire coating.
Using Lubrication: To reduce friction between the pulling grip and the wire coating, using a lubricant such as cable pull lubricant can be beneficial. This lubrication can help ease the movement of the wire through the conduit, reducing the risk of damage.
While fish tape pulling grips are essential tools for electricians, there is a potential risk of wire coating damage if not used correctly. By following the precautions mentioned above, such as choosing the right grip, inspecting it for defects, applying moderate pressure, and using lubrication, the risk of damage can be minimized. It is important to prioritize the safety of the wire coating to ensure the integrity and functionality of the electrical system.
