The Crosby A-1346 Grade 100 welded master link assembly is a high-capacity master link designed for Grade 100 chain sling systems. The higher-grade alloy provides increased WLL in a smaller, lighter package compared to Grade 80, making it ideal for demanding applications where maximum capacity and minimum weight are both critical.
Key Features
- Grade 100 alloy steel — highest capacity in smallest package
- Forged and welded construction
- Lighter weight than equivalent Grade 80 links
- Proof tested at 2x WLL
- 5:1 design factor
Common Applications
- Grade 100 chain sling assemblies
- High-capacity overhead lifting
- Weight-sensitive rigging applications
- Petrochemical and heavy industrial lifting
Standards & Compliance
Meets ASME B30.26. Made in the USA by Crosby.

Inspection & Safety
Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.
WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
