Wire Rope Clips
U Clamp For Wire Rope
A malleable iron U clamp for wire rope used to terminate or join wire rope ends, forming a secure loop or fastening to an anchor point. It consists of a U-bolt, saddle plate, and two nuts. Available in sizes from 3mm to 50mm, it meets DIN 741, DIN 1142, and US Type Malleable standards. The body is malleable cast, the U-bolt is steel, and the finish is zinc plated. Installed in pairs or multiples, it maintains the integrity of the wire rope connection under load.

Key Benefits
What U Clamp for Wire Rope Gives You
- Malleable iron body provides impact resistance and ductility for dynamic rigging applications
- Steel U-bolt ensures high tensile strength and load-bearing capacity
- Zinc plated finish resists corrosion in outdoor and marine environments
- Standardized dimensions to DIN 741 and DIN 1142 allow interchangeability with other certified fittings
- Saddle plate positioned on the live end of the rope prevents wire rope damage during tension
- Simple installation with hand tools allows field assembly without special equipment
- Multiple clips used in sequence increase the strength of the termination to near the wire rope’s breaking load

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Screw pin shackle | U clamp is simpler and cheaper for wire rope termination, but lacks the adjustability and reusability of a screw pin shackle |
| Welded eye splice | U clamp allows field assembly and disassembly, while a welded splice is permanent and requires a welder |
| Cast steel wire rope clip | Malleable iron U clamp is more ductile and impact-resistant than cast steel, but has lower tensile strength |
| Riveted clip | Riveted clips are permanent and not reusable, while U clamps allow repeated use and inspection |
Use Guide
How To Use And Inspect U Clamp for Wire Rope
- Always place the saddle plate on the live end of the wire rope
- Tighten both nuts evenly to avoid misalignment and stress on the U-bolt
- Use at least two clips per termination, spaced according to standard spacing rules
- Inspect the clip and wire rope after initial tensioning and after each use
- Replace the clip if the U-bolt shows signs of stretching or the saddle plate is deformed
- Do not reuse clips that have been subjected to overloading or impact

Answers
U Clamp for Wire Rope FAQ
What is the correct saddle placement on a U clamp?
The saddle plate must be placed on the live end of the wire rope, not the dead end, to prevent wire rope damage and ensure full load transfer.
Can I reuse a U clamp after it has been loaded?
Yes, if the U-bolt, saddle plate, and body show no deformation or signs of fatigue. Inspect before reuse and replace if any damage is found.
What standards do these U clamps follow?
They are manufactured to DIN 741, DIN 1142, and US Type Malleable standards for wire rope clips.
What finish is applied to the U clamp?
The standard finish is zinc plated. Custom finishes such as powder coating or electrophoretic black are available on request.
How many clips are needed for a wire rope termination?
At least two clips are required. For higher loads, use three or more, spaced according to the wire rope diameter and standard spacing rules.
Can you provide Material Test Certificates?
Yes, a Material Test Certificate to EN 10204 3.1 is supplied with each order upon request.
How are the U clamps packed for export?
They are packed in cartons, then palletized. We can configure the carton count and pallet pattern to match your warehouse or retail requirements.
