Couplings Buying Guide

Coupling links are an essential part of rigging, lifting, and recovery systems. They serve as strong, reliable connectors that join chain to chain, or chain to other fittings such as hooks, slings, or master links. Built for demanding industrial and towing applications, couplings are available in both Grade 80 and Grade 100 alloy steel, offering high working load limits for safe and secure operations.

Why Choose Couplings for Rigging and Recovery

A coupling link is designed to provide quick assembly and secure attachment without the need for welding. These links make it easy to replace worn components, connect different rigging parts, or modify a lifting system for a specific job. Heavy-duty coupling links are widely used in transport, overhead lifting, construction, towing, and recovery.

Whether you’re working with alloy chain slings, lifting hooks, or towing gear, a properly rated coupling ensures your equipment performs safely and effectively. Popular options include Grade 100 couplings for higher strength and Grade 80 couplings for standard lifting and load securement needs.

Popular Types of Couplings

Alloy Coupling Links — Designed for connecting chain to hooks or master links.
Container Eye Links — Built for container lifting and specialized rigging setups.
Grade 80 Couplings — Strong and versatile, ideal for many general rigging and recovery jobs.
Grade 100 Couplings — Provide higher working load limits, perfect for demanding or heavy-duty applications.

Shopping Guide for Couplings

When choosing a coupling link, keep these factors in mind:

Application — Decide whether it will be used for towing, overhead lifting, or cargo securement.
Grade — Grade 100 couplings are stronger and support higher working load limits than Grade 80.
Size — Select the correct size to match your chain or rigging hardware.
Compatibility — Make sure the coupling works with your existing hooks, slings, or master links.

Pairing Couplings with Chains and Slings

Couplings are designed to work as part of a complete rigging system. For best results, pair them with compatible chains or slings to create a secure lifting or towing setup.

FAQ About Couplings

What is the difference between Grade 80 and Grade 100 couplings?
Grade 100 couplings offer higher working load limits and strength than Grade 80, making them better suited for heavy-duty lifting and recovery.

Can coupling links be used for overhead lifting?
Yes, as long as they are rated for overhead lifting and paired with compatible chain and hardware. Always check WLL and manufacturer recommendations.

How do I know what size coupling link to use?
The coupling size should match the diameter and grade of the chain or sling you’re using to ensure a safe, secure connection.

Are container eye links the same as standard coupling links?
No. Container eye links are specialized hardware designed for use with container lifting applications, while standard couplings are more general-purpose connectors.
