The design factor is not the same across this range. The manufacturer certifies different sizes differently, so the Design Factor column states the one that governs each size — check the size you are actually buying. The first WLL column is the manufacturer’s published figure for that size and is the rating of record, the figure marked on the product. The 5:1 column is calculated by SlingCenter from that row’s own design factor, for comparison against components rated at the 5:1 commonly specified for wire rope and synthetic sling systems. Where a size is already certified at 5:1 or better, its published Working Load Limit stands unchanged and is marked as such — we never restate a Working Load Limit upward, including where the arithmetic would allow it. Size is the manufacturer’s nominal trade size and does not change between unit views — this part is ordered and stamped by that size in every market; the millimetre figure beside it is the equivalent, not a different size.
The Crosby S-319 shank hook is a versatile lifting hook with a straight shank for insertion into chain links, fittings, or custom mounting points. The forged alloy steel construction provides reliable overhead lifting performance.

Safety & Standards
Every product we carry is individually marked with Working Load Limit (WLL), manufacturer traceability code, and country of origin. Inspection and mill certificates are available on request — email sales@slingcenter.com with your order number.
Governing Standards
- ASME B30.9 — slings (web, round, wire rope, chain) inspection and use
- ASME B30.26 — rigging hardware (shackles, eye bolts, links, turnbuckles)
- ASME B30.10 — hooks
- OSHA 1910.184 and 1926.251 — general industry and construction sling safety
- WSTDA WS-2 and RS-1 — web and round sling design
- 49 CFR 393.102 to 393.130 — DOT cargo tie-down
- NACM — welded steel chain grade specs
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.
WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
