CLGR® G80 U.S. Type Welded Master Link, also known as Grade 80 Master Link Rings, G80 Oblong Recessed Master Link and Grade 80 Master Rings.
The Grade 80 Welded Master Link is a high-strength, forged alloy steel rigging component conforming to ASME B30.26. It is designed to connect multiple legs of chain or wire rope slings for heavy-duty overhead lifting. Featuring quenched and tempered construction and mandatory proof testing, it typically maintains a 4:1 safety factor when used with chain slings.
Each unit undergoes rigorous 2.5× WLL proof testing, 100% magnaflux crack detection, and full material traceability, while its sliding coupling design and silver epoxy finish ensure secure integration in lifting assemblies.
