Product Description
Crosby A-336 Lok-A-Loy® 6 Connecting Links
Crosby A-336 Lok-A-Loy® Connecting Links are forged alloy steel couplers used for connecting chain, master links, and hooks in various rigging assemblies. While they share a similar form to the A-1337 coupling links, the A-336 series carries a lower Working Load Limit (WLL) and must be applied with care when integrated into Grade 80 chain sling systems.
Key Features
- Forged alloy steel construction – quenched and tempered for superior strength and reliability.
- Individually proof tested at 2.5× Working Load Limit (WLL) with certification.
- 4:1 design factor for dependable performance.
- Lok-A-Loy® design allows easy assembly and disassembly using standard link sleeves and pins.
- Meets applicable performance requirements of ASME B30.26 for rigging hardware.
- Permanent identification markings include Working Load Limit, chain size, and Crosby name for traceability.
- When incorporated into a Grade 80 chain sling, the sling must be downrated to match the lower WLL of the A-336 coupler.
- Per ASME B30.9c, the Working Load Limit of a sling cannot exceed the lowest-rated component in the system.
- Not recommended for Grade 100 or higher systems — use the A-1337 coupling link instead.
