Web Sling Shackles
Web Sling Shackles are specialized connection hardware designed exclusively for Synthetic Web Slings (nylon and polyester). Unlike standard anchor shackles, which feature a round bow that causes flat slings to bunch, pinch, or curl, Web Sling Shackles feature a wide, flat bearing surface. This design maintains 100% contact efficiency with the sling eye, preventing internal fiber friction and cutting while maximizing the sling's service life.
Web Sling Shackles
Holloway Houston stocks the Crosby Sling Saver line, including the S-281 Shackle and WSL-320A Hook. These components allow you to connect synthetic slings to pad eyes, hoist rings, or crane hooks without using a thimble. All hardware is fully traceable and compliant with ASME B30.26 .
Hardware Types & Applications
Web Sling Shackles (S-281)
Designed to connect synthetic web slings to industrial hardware. The spool (pin) area is wide and flat, ensuring the load is distributed evenly across the width of the sling fibers.
- Application : Ideal for connecting 1-Ply and 2-Ply web slings to eyebolts or lifting lugs.
- Popular Choice : Check the Crosby S-281 Screw Pin Sling Shackle to eliminate sling bunching and increase the lifespan of your synthetic rigging.
Synthetic Sling Hooks (WSL-320A)
While technically a hook, this hardware is often categorized with web sling shackles because it serves the same protective function. It replaces standard eye hooks to provide a flat bearing surface for the sling eye.
- Application : Used at the bottom of a sling leg to connect to the load, or at the top to connect to a master link.
- Popular Choice : Check the Crosby WSL-320A Synthetic Sling Hook for a safe, non-bunching connection point for web slings.
