* Note: Maximum Proof load is 2 1/2 times the Working Load Limit. Minimum Ultimate Strength is 5 times the Working Load Limit.
• Shackles available in sizes 3 1/4 to 50 tons.
• Hooks available is sizes 1 1/2, 3 and 5 tons.
• Increased radius of bow / eye gives wider sling bearing surface resulting in an increased area for load distribution, thus:
• Increasing Synthetic Sling efficiency by at least 15% as compared to standard anchor and chain shackle bows and conventional eye hooks. This allows 100% of the slings rated Working Load Limit to be achieved.
• Allowing better load distribution on internal fibers.
• Design factor of 5 to 1.
• Shackles available in both a Screw Pin and Bolt, Nut and cotter pin configuration.
• Bolt (Pin) has a larger diameter that provides better load distribution.
• Look for the Red Pin™ … the mark of Genuine Crosby quality.
• Each shackle and hook has a Product Identification Code (PIC) for material traceability along with a Working Load Limit and the name Crosby forged into it.
• All Alloy construction.
• Fatigue rated to 20,000 cycles at 1 1/2 times the Working Load Limit.
