W-39 to W-43 Select The Correct Pulling Grip Each Kellems Grip is designed to work on a specific range of cable diameters. Step 1 Refer to the chart below to determine the style of grip best suited for your application. Step 2 Determine your cable outside diameter. Step 3 Find the grip size that encompasses your cable diameter. Step 4 Estimate the tension to be put on the grip, establish the working load you require and compare this to the listed approximate breaking strength of the grip to insure that the grip will be strong enough. Refer to page W-34 for safety and working load factors. Grips are to be installed and utilized by a qualified technician in accordance with all applicable national and local safety and electrical codes. Consult a licensed project safety professional, if necessary. Ensure that the correct grip is selected for your specific needs. Grips should only be used for their intended purpose and not for other applications. Banding the tail end of the grip is required to prevent unintended release of the grip’s hold from the cable and to achieve maximum gripping strength The strength of a Kellems grips is based on laboratory testing and does not evaluate variable conditions such as cable type, gripping surfaces, cable movement or impact loads. Suitability for the application must be determined by the user. Thoroughly examine the condition of the grip prior to each use. Grips that are worn, bent, corroded, or show other signs of damage, such as frayed or broken wires, should never be used and must be replaced. Do not modify the grip in any way. Ensure that the recommended work load of the grip is suitable for the application. Never use a grip beyond its safe working load, which is the approximate breaking strength divided by the factor of safety. The recommended factor of safety is five (5) for pulling grips and ten (10) for support grips. Pulling hardware should only be attached to the eye of the grip. A swivel is recommended for attachment to the grip’s eye in applications where torque release is necessary. Torque can build up in high tension pulling applications. Do not run grips and swivels around sheaves or bull wheels while under tension. For synthetic rope, use Kellems Dua-Pull Grips only. WARNING: It is very important to read and understand all safety information before proceeding. Failure to use as directed may result in property damage, personal injury or death. Kellems Pulling Grips are reusable tools for pulling electrical cable, bare conductor or rope. They are easy and fast to install, providing the user with a smooth, slim profile that allows for easy passage through ducts and conduit. Kellems Pulling Grips are made of the highest quality galvanized steel strand which assures the user of a long lasting grip. There is a Kellems Pulling Grip for every pulling job. IMPORTANT: Under normal conditions, Kellems’ recommended factor of safety is five for catalog listed pulling grips, and ten for catalog listed support grips.
