Wire Rope Clips: How to Install Them the Right Way
A wire rope clip looks simple, but a clip installed backwards or with the wrong spacing can slip under load. If you are building a cable loop, a guy line, a fence run or a rigging sling, the way the clips are installed matters as much as the clips themselves. This guide walks through the correct method, step by step.
What a Wire Rope Clip Does
A wire rope clip (also called a cable clamp or U-bolt clip) has a U-shaped bolt, a saddle, and two nuts. It grips two parts of the same rope to form a loop or termination without splicing or swaging. Clips are sized by the diameter of the rope they fit, so a 1/4 in. clip is for 1/4 in. rope. Always match the clip size to the rope diameter.
The Golden Rule: Saddle on the Live End
The saddle is the wide, solid base; the U-bolt is the part that bends around the rope. The saddle always goes on the live end (the end that carries the load), and the U-bolt goes on the dead end (the short tail). The common memory aid is "never saddle a dead horse." Putting the U-bolt on the live end can crush and damage the strands that carry the load.
Step-by-Step Installation
- Form the loop. For most terminations, use a thimble in the eye to protect the rope from sharp bends and wear.
- Place the first clip about one clip-base width from the dead-end tail, saddle on the live end.
- Place the second clip as close to the loop or thimble as possible, then snug the nuts lightly.
- Add any remaining clips between them, spaced evenly. Spacing is commonly about six rope diameters; confirm against the table from your clip manufacturer.
- Tighten evenly to the torque the manufacturer specifies for your clip size, alternating between nuts so the U-bolt seats square.
- Apply a load, then re-tighten. Rope settles when first loaded, so re-torque the nuts after the initial load and check them periodically.
Quick Reference
| Item | Correct practice |
|---|---|
| Saddle position | On the live (load-bearing) end |
| U-bolt position | On the dead end (short tail) |
| Clip size | Matches rope diameter |
| Number of clips and torque | Per the clip manufacturer's table for your size |
| Spacing | About six rope diameters, evenly spaced |
| Thimble | Recommended in the eye |
| After first load | Re-torque, then inspect regularly |
Malleable vs Drop-Forged Clips
Malleable galvanized wire rope clips are a cost-effective choice for general-purpose, light-duty jobs such as fencing, guy lines, crafts and non-critical cable runs, and they are sold in larger bulk quantities. Drop-forged wire rope clips are the type generally specified where higher duty is expected. Neither type should be used for overhead lifting or life-safety applications unless the manufacturer's rating and your application's rules specifically allow it. Do not mix clip types or sizes on one termination.
Common Applications
- Cable loops and eyes on aircraft cable and wire rope
- Guy wires, bracing and tie-downs
- Fence and garden trellis cable
- Shop, farm and workshop rigging
- Temporary terminations where a swage is not practical
Common Mistakes to Avoid
- Installing the U-bolt on the live end ("saddling the dead horse")
- Using too few clips or spacing them too tightly
- Skipping the thimble on a tight loop
- Never re-torquing after the first load
- Using a clip that does not match the rope diameter
Buying in Bulk
Shops and contractors who use clips regularly can save with larger pack sizes. We stock malleable galvanized clips in multiple sizes and pack quantities, from small packs to 100-count bags. Pair them with galvanized aircraft cable wire rope for a complete assembly. Contact us for bulk or distributor pricing.

FAQ
Which way do wire rope clips go on?
The saddle goes on the live (load) end of the rope and the U-bolt goes on the dead end.
How many clips do I need?
It depends on rope diameter and the clip manufacturer's table. Follow that table rather than a rule of thumb, and never use fewer than it specifies.
Do I need a thimble?
A thimble is recommended in the eye of a loop. It protects the rope from sharp bending and wear.
Should I re-tighten the nuts?
Yes. Re-torque after the first load is applied, then inspect periodically.
Can I use clips for overhead lifting?
Only where the clip manufacturer's rating and your applicable rules allow it. For lifting, consult a qualified rigger and use properly rated hardware.
Safety note: Wire rope terminations can fail suddenly if installed incorrectly. Follow the clip manufacturer's instructions, wear gloves and eye protection, and never exceed the working load of the weakest component. Not for life-safety or overhead lifting unless specifically rated.
