Crosby Web Sling Shackles
Web sling shackles and oblong master links are the connection hardware at the crane end of synthetic sling assemblies - the fitting that the sling eye loops around before the shackle or link connects to the crane hook. The geometry matters: a standard anchor shackle's round pin can cut into a web sling eye under load. Web sling shackles and oblong master links spread that bearing load over a wider, flatter contact area that's matched to synthetic sling eye geometry.
About Crosby Web Sling Shackles
Web sling shackles are designed specifically for use with flat web (polyester) slings. The shackle body width and pin dimensions are sized to distribute the bearing load across the flat sling eye rather than concentrating it on a narrow pin contact zone. A standard anchor shackle's round pin creates a line load on the sling eye that can cut into the webbing at rated WLL - particularly with narrower sling eyes on higher-WLL applications.
Oblong master links serve a similar function for sling-to-hook connections - the oval body provides the bearing surface geometry that web sling eyes need at the connection point.
Web sling hardware falls under ASME B30.26-2015 (Rigging Hardware) for the hardware itself. The slings these fittings connect to are governed by ASME B30.9-2018 (Slings) and WSTDA WS-1 (Web Slings).

Types of Crosby Web Sling Connection Hardware
Web Sling Shackles
Web sling shackles have a wider body and pin proportioned for the bearing surface of web sling eyes. The shackle pin width distributes the sling-eye load across a broader area than a standard anchor shackle pin. Available in WLL ratings matched to web sling assembly capacities.
Oblong Master Links
Oblong master links provide a wider interior opening than standard oval master links, giving web sling eyes room to seat properly inside the link without the eye bunching against a narrow bearing surface. The oblong geometry also provides more interior area for multi-leg sling assemblies where multiple sling eyes load the same master link.
Crosby Web Sling Shackle Sizes and Working Load Limits
Crosby web sling shackles cover WLL ranges matched to standard web sling assembly capacities. Sizing corresponds to sling width and the sling assembly's rated WLL.
Materials:- Alloy steel body and pin
- WLL marked per ASME B30.26-2015 (Rigging Hardware)
Why Crosby for Web Sling Shackles
The geometry difference between a standard anchor shackle and a web sling shackle is the specific reason web sling shackles exist. Standard shackle pins concentrate bearing load on the web sling eye in a way that degrades the sling material at the connection point over time and can cause premature failure at the eye.
Crosby's web sling hardware provides the bearing surface geometry that synthetic sling manufacturers intend at the connection point, matching ASME B30.26-2015 (Rigging Hardware) hardware requirements with WSTDA WS-1 and ASME B30.9-2018 (Slings) sling assembly requirements.
Holloway Houston also offers rigging inspection services. Their qualified inspectors examine sling assemblies and connection hardware per ASME and WSTDA standards.

Web Sling Shackle Safety and Awareness
Web sling shackles fall under ASME B30.26-2015 (Rigging Hardware). The web slings they connect to are governed by ASME B30.9-2018 (Slings) and WSTDA WS-1 (Web Slings).
Key awareness points:- A standard anchor shackle should not be substituted for a web sling shackle without checking that the shackle pin diameter is appropriate for the sling eye width and WLL. Narrow pins can damage sling eyes at the bearing contact zone.
- Pre-use inspection of web sling shackles covers the body for cracks and deformation, the pin for full seating and thread condition, and the sling eye bearing area on the shackle pin for wear or damage.
- The hardware WLL and the sling WLL both need to meet or exceed the intended load. The assembly capacity is limited by the lower-rated component.
Frequently Asked Questions
A web sling shackle is designed specifically for use with flat web polyester slings. The shackle body width and pin diameter are proportioned to distribute the sling-eye bearing load over a wider area than a standard anchor shackle pin. Standard shackle pins can concentrate load on the sling eye in a way that damages the webbing at the connection point over time, particularly at higher WLL ratings.
Oblong master links are commonly specified at the crane end of web sling assemblies - the wider, longer body provides more interior room for web sling eyes and distributes the bearing load over a broader surface than a standard oval master link. For multi-leg web sling assemblies, the oblong interior accommodates multiple sling eyes without bunching.
