Crosby 'S281' Web Sling Saver Shackle, WLL Range from 2950kg to 7700kg

Web Sling Shackle is designed to connect Synthetic Web Slings and Synthetic Round Slings to eyebolts, pad eyes, and lifting lugs.

• 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.
• 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 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.
• Allows better load distribution on internal fibers.
• Meets or exceeds all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements. Importantly, these shackles meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.

*Designed for use with Type III, (Eye & Eye), Class 7, 2 Ply web slings.

†Maximum Proof Load is 2-1/2 times the Working Load Limit. Minimum ultimate strength is 5 times the Working Load Limit.

Note: For 3" and larger webbing widths, tapered eye is required.

Crosby Sling Saver hardware meets the requirements for minimum stock diameter or thickness, and effective contact width shown in the Recommended Standard Specification for Synthetic Polyester Roundslings by the Web Sling & Tie Down Association. WSTDA-RS1 (revised 2010)
