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. Pound figures are converted by SlingCenter from the manufacturer’s metric rating at 1 t = 2,204.62 lb and rounded down — a unit conversion only, not a change of rating. The metric figure is the rating of record. Lowercase t is the metric tonne (1,000 kg / 2,204.62 lb), the manufacturer’s own notation — not the US short ton. 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 G-2140 is an alloy steel bolt type anchor shackle engineered for demanding overhead lifting where higher strength-to-weight ratio is required. Manufactured from quenched and tempered alloy steel and fitted with a bolt, nut, and cotter pin to prevent accidental opening, it carries a design factor that varies by size (see the Technical Specifications tab) per ASME B30.26 and is proof tested at twice the Working Load Limit.
Key Features
- Alloy steel construction — higher strength-to-weight than carbon steel shackles
- Bolt, nut, and cotter pin prevents accidental opening under vibration or shock
- Quenched and tempered for maximum impact toughness
- Proof tested at 2x WLL with individual certificates available
- Fatigue rated per Crosby engineering standards
- Embossed WLL and heat number traceability markings
Common Applications
- Critical overhead lifts requiring higher capacity in a lighter package
- Offshore lifting and subsea rigging
- Crane and hoist permanent terminations
- Wire rope socketing and assembly
- Industrial and energy sector lifting operations
Standards & Compliance
Manufactured to ASME B30.26 with full traceability. design factor that varies by size (see the Technical Specifications tab) (alloy). Made in the USA by Crosby.
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).
