Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-318 is a forged steel clevis hook with latch, designed for making quick, secure connections with chain in industrial and construction applications. The hook meets Grade 70 specifications and carries a safe working load of 6,600 pounds. A removable clevis pin simplifies rigging setup and breakdown. The yellow chromate finish serves as a visual indicator for Grade 70 identification in the field. This hook is not rated or designed for overhead lifting and should only be used in transport and tie-down applications.

This hook is suited for use with Grade 70 transport chain or chain of a lower grade rating. Typical applications include cargo securement, flatbed transport tie-down, and industrial rigging connections where quick chain attachment is required.
