WORKING LOAD LIMIT: 1/2 TO 55 TONS

CM Super Strong Shackles are carbon-type shackles 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. Anchor shackles can be side loaded or used for multiple connections.

Features & Benefits

  • Manufactured from technically advanced micro alloy steel with optimal hardness for strength and ductility.
  • Shackles show major deformation before failure
  • Working load limit and traceability codes shown as permanent markings on body
  • All shackles have alloy quenched and tempered pins
  • Available in sizes 3/16″ to 2-1/2″
  • Available finishes include powder coated, galvanized or self-colored
  • Shackles meet dimensional requirements and exceed performance requirements of RR-C-271
  • Special testing and certification is available upon request at the time of the order
  • Note: Screw pin and bolt/nut/cotter shackles have a 6:1 design factor. Round pin shackles have 5:1 design factor.
