Dimensions per the Crosby L-320N / L-320 Eye Hooks catalog (Hooks & Swivels). Design factor 5:1 (1–22 t alloy); proof load 2.5× WLL. The 22 t “D” dimension is taken from Crosby’s metric specification (262 mm ≈ 10.38 in), correcting a typographic error in Crosby’s published imperial table. Latch-clearance dimensions (O, T) are shown on the additional Crosby diagrams — contact us if you need them.

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).
