The Crosby A342CT Cold-Tuff Master Links are manufactured from alloy Steel, quenched and tempered. A master link is commonly used as the top anchorage/connector on a chain sling though they are also used a stand-alone lifting connector. They are individually proof tested at 2 times Working Load Limit with certification. The finish is inorganic zinc primer. Individually serialized and all certification shipped with each link. COLD TUFF master links are suitable for use at -50 F.
