Industrial A61 Grade 80 Forged Alloy Steel Coupling Link

The HMC A61 Grade 80 Forged Alloy Steel Coupling Link is a heavy-duty lifting connector forged from alloy steel, designed to connect chain slings, hooks, and lifting assemblies while preserving full load capacity in overhead lifting and rigging systems. It features a 1/2 in chain size and a 12,000 lb working load limit, with a minimum design factor of 4:1, and is intended for use with Grade 80 lifting chains in demanding industrial environments such as material handling, construction, and shipyards, for both indoor and outdoor operations. Constructed from forged alloy steel and finished with a powder coat or paint finish (varies by manufacturer), this coupling link provides a secure, durable connection point for chain slings, cranes, hoists, lifting beams, and rigging assemblies, while meeting ASTM A952 and NACM specifications for Grade 80 lifting components. Common replacements include Crosby A-342 Grade 80 Coupling Link, Peerless Hammerlok Grade 80, and Gunnebo BK Grade 80 coupling links.
