Key Benefits
What Duplex Wire Rope Clamp | Double Wire Rope Clip Gives You
- Secures two wire ropes in parallel with a single clamp, reducing the number of fittings needed
- Electrical galvanized finish resists corrosion in outdoor and marine environments
- Drop-forged and cast construction provides strength and impact resistance
- Even bolt tightening distributes load across both wire ropes to prevent slippage
- Suitable for both temporary and permanent connections in dynamic or static loads
- Available in carbon steel, stainless steel 304, and stainless steel 316 for different corrosion resistance needs
- Standardized dimensions allow for consistent fit across common wire rope diameters
Application Scenarios
Where Duplex Wire Rope Clamp | Double Wire Rope Clip Is Used
- Creating a secure loop in a wire rope sling by joining two ends with a duplex clamp
- Connecting two wire ropes in a rigging setup where a single anchor point is needed
- Securing the end of a wire rope to a fixed structure such as a beam or anchor point
- Marine mooring systems where corrosion resistance and high strength are required
- Construction site hoisting and lifting operations with frequent rope re-termination
- Temporary guy wire installations on towers or scaffolding using multiple rope strands
- Industrial machinery where wire rope ends are fastened to pulleys or drums

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 |
|---|---|
| Single wire rope clamp | The duplex version secures two ropes in one fitting, reducing parts count and connection complexity |
| Screw pin clamp | The bolt and nut design allows for even tightening and better load distribution than a screw pin |
| Malleable iron clamp | Drop-forged and cast construction offers higher strength and impact resistance than malleable iron |
| Stainless steel single clamp | The duplex version provides dual rope security, while a single clamp only handles one rope at a time |
Use Guide
How To Use And Inspect Duplex Wire Rope Clamp | Double Wire Rope Clip
- Ensure both wire ropes are parallel and of the same diameter before clamping
- Center the wire ropes within the clamp grooves before inserting bolts
- Tighten bolts evenly and progressively to avoid misalignment or rope damage
- Use an appropriate torque wrench to meet manufacturer recommendations
- Inspect the clamp regularly for signs of wear, corrosion, or bolt loosening
- Replace the clamp if the body shows deformation or the finish is compromised
- Do not reuse clamps after a load failure or visible damage
