Crosby® S-281 Web Sling Shackle
Product Information
Description
• Incorporates same ear spread and pin dimensions as conventional Crosby Shackles.
• Allows easy connection to pad eyes, eye bolts and lifting lugs.
• Increased radius of bow 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 sling’s rated Working Load Limit to be achieved.
• Allowing better load distribution on internal fibers.
• All Alloy construction.
• Design Factor of 5 to 1.
• Each shackle has a Product Identification Code (PIC) for material traceability along with a Working Load Limit and the name Crosby forged into it.
