Crosby® S-253 20.5 Ton Web Sling Shackles - For High-Capacity Synthetic Sling Connections

Designed for serious lifting applications, the Crosby S-253 Web Sling Shackle features a squared bow profile specifically engineered for synthetic slings. The wide contact surface eliminates bunching and sliding while allowing the sling to fully engage its rated capacity-boosting sling efficiency by at least 15% compared to traditional shackles and hooks.

This heavy-duty shackle supports secure connections to pad eyes, lifting lugs, and eye bolts, particularly when used with wide web slings or large-capacity round slings. The forged alloy steel body includes a non-slip finish and a screw pin closure for secure, easy rigging in field conditions.

Each unit is made in the USA and stamped with the Crosby name, working load limit (WLL), and PIC code for clear traceability and compliance. The shackle is proof load tested to 2.5x its rated capacity for added assurance under high-stress operations.

• Squared Bow Design: Provides greater load-bearing area, improving sling performance and longevity.
