How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Standard master link without flat subring | The flat-engineered subring prevents misalignment during assembly, reducing risk of uneven load distribution and chain wear |
| Non-proof tested master link | Each unit is individually proof load tested, providing documented safety assurance not found in untested units |
| Master link without working load limit marking | working load limit marking on each unit supports compliance with European lifting equipment standards and simplifies export documentation |
| Painted finish instead of powder plastified | Powder plastification offers superior abrasion and corrosion resistance compared to standard paint |
Use Guide
How To Use And Inspect G80 European Type Master Link Assembly A346
- Verify the stamped WLL and size match the intended lifting application before use
- Inspect the subrings for flat alignment before assembling the chain sling
- Ensure the working load limit marking and WLL stamp are legible and undamaged before each lift
- Do not exceed the rated working load limit under any condition
- Check for surface cracks, deformation, or coating damage before and after each use
- Retire the master link if the body shows permanent deformation or the marking is no longer readable
- Use only with Grade 80 EN818-2 lifting chains and in 3 or 4 leg configurations as designed

Answers
G80 European Type Master Link Assembly A346 FAQ
What is the proof load test multiple for this master link?
Each unit is proof load tested. The minimum breaking load is four times the WLL, as per standard design factor.
Is the working load limit marking applied to every unit?
Yes. Each master link is marked with CE, size, and WLL. The marking is applied directly to the forged body for traceability and compliance.
Can the subrings be flat-engineered for alignment?
Yes. The subrings are engineered with a flat profile to prevent misalignment during chain sling assembly, reducing the risk of uneven load distribution.
What surface finish is used and can it be changed?
The standard finish is powder plastified in red RAL3020 and yellow RAL1003. Custom finishes including zinc plating, electrophoretic black, or powder coating in other colors are available.
Are Material Test Certificates available?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with each order upon request. It includes material composition and mechanical properties.
Can custom sizes be made?
Yes. Custom sizes and dimensions can be built to a supplied drawing. The design must align with Grade 80 EN818-2 chain compatibility.
