CM STAC with Tag - Special Theatrical Alloy Chain

From the leader of entertainment production technology, CM’s STAC (Special Theatrical Alloy Chain) Grade 80 is a super strong chain product that we frequently use at our own job sites. CM STAC (commonly referred to as "deck chain") is designed to provide superior strength for theatrical rigging applications where bridle adjustability is required. Each link is proof tested and manufactured using heat-treated steel for longevity. CM STAC is made in the USA and now also meets European standards for long link chain. Links accept up to 3/4” shackles for bridle adjustability.

CM is an expert in chain manufacturing, with endless experience in industrial chain products as well as the entertainment-focused chain. CM STAC has been specially designed to give riggers a strong chain product that is easily identified via CM embossed markings. This positive identification increases safety and aids in the inspection process.
