Coupling Links – Essential Chain Connectors
Coupling links (also known as Hammerloks, Lok-A-Loy's, connecting links, or couplers) are essential for securely joining chain legs, hooks, and master links in lifting assemblies.
Key Uses:
- Connect chain legs to master links.
- Attach fittings like grab hooks.
- Join eye hooks (e.g., foundry hooks) to chain slings.
Popular Coupling Links:

Selecting the Appropriate Coupling Link
When choosing a coupling link, consider the following factors:
- Load Requirements: Ensure the coupling link's working load limit aligns with your lifting application.
- Compatibility: Verify the coupling link matches the chain size, type, and assembly components.
- Environmental Conditions: Choose a coupling link suited to your operational environment (e.g., temperature variations, chemical exposure, moisture).
Selecting the right coupling link enhances the safety and efficiency of your rigging operations.
