WLL: 2 to 150 Tons Sizes: 3/8 to 3-1/2 in.
CM Alloy Shackles are designed with a 5:1 design factor and have a strength rating approximately 50% higher than a comparable-sized carbon shackle and about 25% stronger than super strong shackles. Anchor shackles can be side loaded or used for multiple connections.
3/8” to 2” sizes made in the U.S.A. from domestic (U.S.A.) Special Bar Quality (SBQ) steel having fine grain, reduced sulfur and phosphorus. 2-1/2” to 3-1/2” sizes forged form high-quality German alloy steel at our STB facility in Hamm, Germany and then finished in the U.S.A.
Shackles show major deformation before failure
CM shackles are forged to shape rather than bent like the competition. This allows for better shackle identification markings and dimensional consistency.
Working load limit and traceability codes shown as permanent markings on body
All shackles have alloy quenched and tempered pins
Available in sizes 3/8" to 3-1/2"
Available finishes include powder coated, galvanized or self-colored
Shackles meet dimensional and performance requirements of RR-C-271
Special testing and certification is available upon request at the time of the order.
CM Smart ID RFID technology is available as an option on screw pin anchor shackles sizes 1/2" to 1-3/4" and bolt, nut & cotter shackles sizes 3/4" to 1-3/4".

High-capacity alloy shackles (2-1/2" to 3-1/2") also feature:
Convenient articulating lifting points on the bolt allow for easy rigging and transport.
Feature higher average Charpy values than the competition, delivering better performance and exceptional toughness in cold temperature applications.
