Crosby A-1343 Master Link – DNV Type Approved. 100% Proof Tested. Zero Compromises.
The Crosby A-1343 Master Link sets the benchmark for certified, traceable, high-performance master links in overhead lifting and offshore sling systems. Every single unit is 100% proof tested and impact tested — not batch sampled, not statistically inferred — with 3.1 test certification available upon request. When your project demands documented evidence of performance on every component, the A-1343 delivers it.
DNV 2.7-1 Type Approved for Offshore Use
The A-1343 carries DNV type approval to Certification Notes 2.7-1 for offshore containers — one of the most demanding certification frameworks in the global lifting industry. For offshore platform, marine, and subsea lifting contracts where DNV compliance is a contractual requirement, the A-1343 arrives pre-approved and ready to document.
Engineered Flat. S-1325A Compatible.
The A-1343 is engineered flat specifically for use with the Crosby S-1325A coupler link — ensuring correct orientation, full bearing engagement, and optimal load distribution in multi-leg sling assemblies. Proof tested using 70% inside width special fixtures sized to prevent localized point loading per EN 1677-4, the A-1343's testing methodology reflects real-world load conditions rather than idealized lab setups.
Beyond ASME B30.26 — Fatigue, Impact & Traceability Built In
Meeting or exceeding all ASME B30.26 requirements for identification, ductility, design factor, proof load, and temperature is the starting point — not the finish line. The A-1343 additionally addresses fatigue life (rated to 20,000 cycles at 1.5× WLL), impact properties, and full material traceability. Each link is permanently marked with its PIC code, Grade, CE marking, chain size, and CG (Crosby Group) identifier for complete field traceability from manufacture to lift.
Built from quenched and tempered alloy steel to a 5:1 design factor, the A-1343 is the master link of choice for riggers, sling assemblers, and lifting engineers who won't accept anything less than fully documented, independently verified performance.
Key Applications:
- Overhead lifting sling assemblies requiring DNV certification
- Offshore container and platform lifting to DNV 2.7-1
- Grade 80 and Grade 100 chain sling terminations
- Multi-leg sling systems with S-1325A coupler links
- Certified lifting contracts requiring 3.1 material documentation
