Shackles (Bow & Dee, Screw Pin)

Shackles are the standard connector for lifting, rigging and towing systems, joining chain, wire rope slings and web slings to loads and anchor points. Bow (omega) shackles give a wider opening for multi-leg slings, while dee (D) shackles suit single-leg, straight-line pulling. Every shackle we supply is stamped with its working load limit.
