OneMonroe rigging shackles are designed for safe and reliable lifting, towing, and load securement applications across construction, marine, transportation, and industrial environments. Available in a variety of styles, sizes, materials, and load capacities, these shackles provide the strength and durability required for demanding rigging operations.
All shackles meet or exceed Federal Specification RRC-271D and feature permanently marked Working Load Limits and traceability codes on the body and pin. Available in painted, galvanized, and self-colored finishes, they include alloy quenched and tempered pins for added strength. Independent testing has verified extreme deformation before failure, while optional testing and certification services are available upon request. Custom engineering solutions are also offered, and all shackles are manufactured with a 5:1 design factor.
