Note: *Most catalog listed support grips are made of tin-coated bronze strand. To order stainless steel support grips, change the first three catalog number digits from

022-0x-xxx to 024-0x-xxx. Consult Technical Service for details.

Eye Styles

Select the Correct Support Grip

Each Kellems grip is designed to work on a specific

range of cable diameters.

Step 1 Refer to the Kellems chart below to determine

the grip style 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 Whenever possible, use a closed mesh that

assembles over the cable end. If the cable end

is not available, use a split mesh.

Step 5 Where available, select an eye style that suits

your needs.

Step 6 Select the proper material—tinned bronze or

stainless steel*.

Step 7 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 V-42 for safety

and working load considerations.

Technical Information

Support Grips

Kellems® Support Grips

Kellems Support Grips are used to hold the weight of electrical cable as it hangs in a vertical, sloping or horizontal position.

Electrical cable must be supported, or its dead weight can cause excessive strain or pullout at the connections resulting in

power failure. Support grips also absorb additional strain from flexure, vibration, expansion and contraction. Kellems Support

Grips listed in this catalog are made of high grade, non-magnetic tin-coated bronze strand. Stainless steel grips, made of alloy

302–304 SST for severe service or unusual environmental conditions, are available on request.

1. Support grips are to be installed by a qualified individual in

accordance with all applicable national and local safety, electrical

and rigging codes.

2. Ensure that the correct grip is selected for your specific needs.

3. Do not use a support grip for any application other than

supporting cable.

4. Thoroughly examine the grip for damage. Do not use a damaged grip.

5. 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 10 is recommended for support grips.

6. Do not alter grips in any way. For example, do not flatten, straighten,

bend or otherwise modify eye tubes, hooks, and strand equalizers.

7. Do not attach any type of hook, clamp or other hardware directly to

the stranded bale of a “U” eye support grip. The formed eye tube is

the only acceptable means of attachment to external hardware.

8. 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.

CAUTION: It is very important to comply with all of the

following precautions.
