Chain Couplings and Component Connectors for Safe and Flexible Rigging

Our range of component connectors and chain coupling links are designed for assembling and maintaining safe, efficient lifting slings. Whether you're replacing worn-out connectors or building a multi-leg chain sling from scratch, our high-strength chain couplers make it simple, secure, and fully compliant with industry standards.

These components serve as the critical connection point between chain and hardware — such as hooks, masterlinks, or sub-assemblies — without the need for welding. Used across 1-, 2-, 3-, and 4-leg sling configurations, they allow for flexible, modular sling design while preserving full Working Load Limits (WLL).

• Compatible with both Grade 80 and Grade 100 chain
• Designed for use in overhead lifting applications
• Heat-treated, proof-tested, and traceable by serial or batch marking
• Assembled and tested in Houston, Texas using imported components

Whether you refer to them as chain couplers, sling connectors, or coupling links, these parts do the heavy lifting — safely connecting your chain to hooks, masterlinks, or other hardware.

What is a Chain Coupling or Chain Coupler?

A chain coupling (also known as a chain coupler) is a mechanical connector that links lengths of lifting chain to other components, like hooks or masterlinks. Unlike welded connections, these couplers are reusable and replaceable, making them ideal for modular sling systems. They’re commonly used in rigging, construction, manufacturing, and logistics to build chain slings of 1 to 4 legs.
