National Mfg N240-382 Zinc Cold Shut 1/2 Inch

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N240-382 is a zinc-plated cold shut designed for temporary chain link repair and chain coupling applications. Cold shuts are single-use fasteners that close around a chain link or attachment point without requiring tools for initial placement. This 1/2 inch cold shut is sized for use with chain one size smaller, following standard practice of selecting a cold shut one size larger than the chain being repaired or connected. It is commonly installed by maintenance technicians, riggers, and general trade professionals in light-duty chain repair scenarios.

This cold shut is suited for temporary repairs on chain assemblies in residential, commercial, and light industrial settings. It can also couple chain attachments where a quick, tool-free connection is needed. The part ships in a bulk bag of 10 units, making it practical for service vans, maintenance kits, and supply rooms. Because this fitting is intended for temporary use only, it should not be substituted for a permanent chain repair link in load-bearing or safety-critical applications.

Key Features

• Zinc construction for corrosion resistance in general-purpose environments
• 1/2 inch size — select one size larger than the chain being repaired
• Suitable for temporary chain link repair and chain coupling tasks
• Single-use design — do not reuse after closure
• Bulk bagged in quantities of 10 for shop and service use

Compatibility

Designed as a temporary repair and coupling fitting for 1/2 inch-class chain assemblies. Use one size larger than the chain being serviced. Not rated for permanent load-bearing or overhead lifting applications.

Installation Notes

Cold shuts are installed by hand or with light-duty pliers to close the link around the chain. Always verify that the cold shut size is one increment larger than the chain size before installation. This fitting is single-use only — once closed, it must not be reopened and reinstalled. Do not use cold shuts as a permanent replacement for welded or rated chain repair links in overhead or load-bearing rigging.
