Carbon Anchor Shackles

OneMonroe Carbon Anchor Shackles are engineered for heavy-duty lifting, towing, and rigging applications where strength, reliability, and safety are essential. Manufactured from advanced microalloy materials and equipped with alloy quenched and tempered pins, these shackles deliver exceptional performance in demanding industrial, construction, marine, and transportation environments. Their robust design helps ensure secure load connections while providing dependable operation under challenging conditions.

Available in a variety of sizes and finishes, Carbon Anchor Shackles meet or exceed Federal Specification RRC-271D and feature permanently marked Working Load Limits and traceability codes for easy identification. Independent testing has shown that the advanced microalloy construction offers superior performance compared to traditional carbon materials, including improved resistance to shock loading and greater deformation before failure. With optional testing and certification services available, these shackles provide a trusted solution for critical lifting and rigging applications.
