CM makes their S.T.A.C. line of chain (Special Theatrical Alloy Chain) specifically to meet the needs of the theater and motion picture industries. It is made from beefy 1/2" Grade 80 alloy steel and carries a 12,000 lbs Working Load Limit. It has large interior dimensions to allow easy connection of shackles (it pairs great with CM's Black Theatrical Rigging Shackles, sold separately). The chain is heat-treated and each link is proof-tested to ensure weld and material integrity. Available in cut lengths or by the drum. Each cut length ships with a tag indicating size, grade, reach and Working Load Limit.
