Gunnebo M & MF Master Links (Grade 100)

Gunnebo M and MF Master Links are heavy-duty, welded alloy steel links designed for use with Grade 100 chain slings and other lifting assemblies. The M series features a consistent round profile, while the MF series incorporates an engineered flat to accept certain compatible fittings (such as components from the GrabiQ lineup or Crosby S-1325 Omega Links). This versatility makes them a reliable choice for both standard chain sling assemblies and specialized rigging applications.
