Kellems® Wire Management Products Pulling / Splicing Grips Cautions & Warnings
Safety and Working Load Factors For Wire Mesh Grips
The broad application of Kellems grips on a wide variety of objects requires that adequate safety factors be used to establish working loads. The approximate breaking strength of a Kellems grip represents an average calculation based on data established from actual direct tension testing done in our engineering laboratories.
It is impossible to catalog or guarantee a safety factor suitable for all applications as operating conditions are never the same. The tension, diameter, movement, number of objects gripped, gripping surface, and the attachments used are just some of the factors which vary with each application. These factors, together with the effects of abrasion, corrosion, prior use or abuse and any other variables of a specific application, must be considered by the user and the grip replaced as appropriate. Where the conditions of the application are not well defined or known, or where risk of injury to persons or property is involved, a greater safety factor should be utilized.
Under normal conditions, Kellems’ recommended factor of safety is five for catalog listed pulling grips, and ten for catalog listed support grips. Any warranty as to quality, performance or fitness for use of grips is always premised on the condition that the published breaking strengths apply only to new, unused grips, and that such products are properly stored, handled, used, maintained and inspected by the user at a frequency appropriate for the use and condition of the grip.
It is very important to comply with all of the following precautions. Failure to do so may result in property damage, personal injury or death.
- Pulling grips are to be installed by a qualified individual in accordance with all applicable national and local safety, electrical and rigging codes.
- Ensure that the correct grip is selected for your specific needs.
- Do not use a pulling grip for any application other than pulling cable.
- Thoroughly examine the grip for damage. Do not use a damaged grip.
- Ensure that the recommended work load of the grip is suitable for the application. Never use grips at their approximated rated breaking strength. A safety factor of 5 is recommended for pulling grips.
- Do not alter grips in any way. For example, do not modify pulling eyes, shoulders, fittings or lugs.
- Do not attach any type of pulling hardware to any point on the grip other than the pulling eye. The pulling eye is the only acceptable means of attachment to external hardware.
- Always apply 2 bands at 1″ and 2″ respectively, from the tail end of the mesh to guard against accidental release of the grip. Accidental release can occur if an object contracts and pushes against the tail end of the mesh, thereby expanding and releasing it’s hold.

Klein Tools Pulling Grips Warnings
- Before each use, clean jaw area and inspect grip for proper operation to avoid slippage.
- When used on/near energized lines, ground, insulate, or isolate grip before pulling.
- Do not exceed rated capacity.
- Always match proper size and type of grip to application.
- Grips are to be used for temporary installation, not for permanent anchorage.
