The primary benefit of using these is that the user can gain extra height when positioning a work piece compared to a top mounted ring; they are rated at 100% WLL for angles up to 90°. Simply use a shackle to connect to a wire rope/sling, passing the pin through the ring for maximum security and loading. Crosby® recommend using their own red pin shackles (page 174) and we have listed the recommend sizes and codes below. Individually stamped with a PIC [Product Identification Code] for material traceability, along with the WLL. They are individually proof tested to 2.5 x stated WLL. We’ve opted to stock three sizes, but all Crosby® products are available to order. Please note, the full thread length must be fully engaged with the work piece rather than passed through and secured with a nut - they should be fitted using a torque wrench set to the recommended torque. The user should always follow manufacturer’s assembly and safety guidance.
