National Mfg N830-315 Clevis Hook Latch 1/4 Inch Grade 70

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-315 is a forged steel clevis hook with latch designed for making quick, secure connections with chain in industrial and construction applications. Built to meet Grade 70 hook specifications, this hook features a removable clevis pin for easier rigging setup and a yellow chromate finish that provides instant visual identification as a Grade 70 component. The safe working load is 3,150 pounds. This is not designed for overhead lifting and must not be used in overhead lifting applications. Licensed HVAC, rigging, and construction trades rely on this type of hardware for load securement and chain attachment in transport and tie-down scenarios.

The N830-315 clevis hook with latch is intended for use with Grade 70 transport chain or with chain of a lower grade. It is suited for industrial and construction environments where fast, reliable chain connections are required. The package contains 3 hooks, making it practical for multi-point securement setups. The latch keeps the hook closed during use, reducing the chance of accidental disengagement under load. This product is appropriate for transport tie-down, load binders, and general chain rigging work where overhead lifting is not involved.

Installation Notes

Installation and rigging of load-bearing chain hardware should be performed by qualified personnel familiar with applicable load securement standards. Always verify the working load limits of all chain and hardware components before use, and never exceed the rated safe working load of 3,150 pounds. Do not use this hook for overhead lifting under any circumstances. Inspect the latch and clevis pin for wear or deformation before each use and replace any damaged components immediately.
