Crosby A-1337 Lok-A-Loy® 10 Coupling Link – Grade 100 Assembly. Tool-Free. Full WLL Maintained.
Building and repairing alloy chain sling systems demands connectors that match the strength of the chain itself — without introducing weak points, requiring special tooling, or slowing down assembly. The Crosby A-1337 Lok-A-Loy® 10 Coupling Link delivers on every count. Engineered specifically for Grade 80 and Grade 100 alloy chain sling systems, the A-1337 maintains the full Working Load Limit of the connected sling assembly while providing fast, reliable, tool-free connection between chain, master links, and hooks.
Lok-A-Loy® Design – Fast Assembly, No Tools Required
The A-1337's Lok-A-Loy® alloy locking pin and sleeve system allows quick, secure coupling without specialized installation tools — reducing assembly time on the shop floor and in the field without compromising connection integrity. The locking mechanism positively engages to prevent accidental disassembly under load, vibration, or dynamic lifting conditions, giving riggers and sling assemblers confidence that the connection will hold throughout the lift.
Permanently embossed with "P 10" in a high-visibility black finish, every A-1337 is instantly identifiable as a genuine Grade 100 (Peerless/Grade 10) component — supporting accurate sling assembly, inspection, and load planning in busy rigging environments.
Forged from quenched and tempered alloy steel to a 4:1 design factor, individually proof tested at 2.5× WLL with certification, and fatigue rated in sizes 9/32" to 1", the A-1337 meets or exceeds ASME B30.26, EN 1677-1, and ASTM A952/A973 requirements for Grade 100 fittings — covering North American and European certification standards in a single approved component.
Key Applications:
- Assembling and repairing Grade 80 and Grade 100 chain slings
- Connecting alloy chain to master links, hooks, and end fittings
- Overhead lifting in industrial, construction, and manufacturing environments
- Certified chain sling assemblies requiring full WLL traceability
