Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-316 is a 1/4 inch clevis grab hook forged from yellow chromate-finished steel and rated to Grade 70 specifications. It is designed for making quick, secure connections with transport chain in demanding industrial and construction environments. The removable clevis pin simplifies rigging setup and breakdown without additional tools. The yellow chromate finish serves as an immediate visual indicator of Grade 70 rating, allowing workers to verify hook-to-chain grade compatibility at a glance. This hook is suitable for use with Grade 70 transport chain or any chain of a lower grade rating.

This hook is intended for industrial and construction rigging applications where fast chain connections are required. Typical use scenarios include load securing, tie-down rigging, and transport chain assemblies on job sites. The clevis-style mounting allows the hook to attach to chain links or anchor points without permanent installation. It is packaged loose in a retail box and sold in a package quantity of 3 units per package, making it practical for fleet servicing or multi-point rigging setups.

Installation Notes

Installation and rigging work involving load-bearing hooks should be performed by qualified riggers familiar with applicable ASME B30 rigging standards. Always inspect the hook, clevis pin, and chain for wear, cracks, or deformation before each use. Verify that the hook grade rating matches or exceeds the grade of chain being used. Never exceed the working load limit stamped or rated for the assembly.
