The Crosby S-252 is a bolt-type Sling Saver shackle designed for use with both synthetic web slings and round slings. The increased radius of the bow provides a wider sling bearing surface for better load distribution across internal fibers, allowing 100% of the sling's rated Working Load Limit to be achieved. The larger-diameter bolt (pin) further improves load distribution.
Key Features
- Bolt-type (bolt, nut and cotter) Sling Saver shackle
- Suitable for synthetic web slings and round slings

Inspection & Safety
Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.
