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 in bulk. Each cut length ships with a tag indicating size, grade, reach and Working Load Limit.
