CM Super Strong Shackles are manufactured using micro alloy with strength ratings that are 17 to 50% stronger than comparable sized carbon shackles. As a result, these shackles are designed with a 6:1 design factor. CM micro alloy shackles can be side loaded or used for multiple connections with minimum loss of strength compared to standard carbon shackles. CM super strong shackles are Manufactured from technically advanced domestic (U.S.A.) micro alloy steel with optimal hardness for strength and ductility. CM super strong shackles meet dimensional requirements and exceed performance requirements of RR-C-271
