Wire rope clips are a common piece of rigging hardware for working with wire rope.  They are used to form a wire rope eye or to connect two cables together. It’s important to understand how to correctly install a wire rope clip.  Wire rope clips, when applied correctly have an 80% efficiency rating.  Incorrect installation leads to decreased efficiency in the wire rope assembly. 

Parts of a wire rope clip:

When using wire rope clips, the manufacturer of the wire rope will specify the length of turnback required to create the assembly. In this instance, 3 ¼” is required.

Starting one base width from the dead end (marked with tape), attach the first wire rope clip. Attach the nuts to 4.5 ft. pounds by tightening the two nuts incrementally, alternating between them.   Be certain that the LIVE end (Long Side) of the wire rope is resting in the saddle of the wire rope clip.

“NEVER SADDLE A DEAD HORSE”

Insert the thimble to form the “eye” and then apply the second clip at the narrow end. Tighten as directed in Step 3.

Apply a load equal to, or greater than the weight anticipated. Re-tighten to recommended torque. The wire rope will elongate while under load and will need to be retightened.

1. The live end of the wire rope must be resting in the saddle.

2. You must use a torque wrench to tighten to the manufacturer’s specified torque. If you fail to use a torque wrench, it will be impossible to determine the breaking strength of your assembly.

3. When applied correctly, wire rope clips are 80% efficient. That means, if the wire rope has an ultimate breaking strength of 2000lbs., applying the wire rope clips will reduce that strength to 1600lbs.

4. Wire rope clips can be used again, however, do not reuse wire rope.

5. If using the iRigging App, please remember that measurements in the USA are “Imperial”. The app will indicate other information including the number of clips required.

IMPORTANT SAFETY NOTE:  The wire rope and termination should be inspected periodically for wear and abuse.
