Carbon Anchor Shackles

Features:
• All shackles meet or exceed Federal Specification RRC-271D
• Working Load Limit and traceability codes shown as permanent marking on body and pin
• Available in painted, galvanized and self-colored finishes (Dacromate coating upon special request only)
• All shackles have alloy quenched and tempered pins
• Shackles made from technically advanced microalloy material
• Load break tests consistently show microalloy outperforms quenched and tempered carbon material
• Shock load testing of assemblies at -30ºF consistently demonstrate microalloy outperforms quenched and tempered
carbon material*
• Shackles exhibit extreme deformation before failure*
• Special testing and certification including magnetic particle, proof load, and fatigue test available upon request at time of
order
• Special products engineering available to fit your special lifting, tie down, and pulling needs
• Design factor 6:1 (Round pin shackles design factor 5:1)
