What Is a Cold Shut and How Do You Use It?
A cold shut is a simple link used to join chain or rope ends permanently. It is common in chain assemblies and marine work, but it is easy to install badly. This guide explains what a cold shut is and how to use it.
What Is a Cold Shut?
A cold shut, also called a cold shut link, is an oval or round link with an open slot. The ends are closed by hammering or pressing the link together to form a permanent connection. It is used to join chain, rope or fittings where a removable link is not wanted.
Cold Shut vs Lap Link
A cold shut is closed permanently, while a lap link has a removable pin or screw so the connection can be opened again. For an inspection-friendly or temporary connection, a lap link or connecting link is often the better choice.
How to Install a Cold Shut
Pass the cold shut through the chain links or rope eyes.
Close the slot so the ends meet tightly.
Hammer or press the ends closed without cracking the metal.
Check that the link is fully closed and cannot open under load.
Where Cold Shuts Are Used
Cold shuts are used in chain assemblies, mooring, fishing gear and general rigging. They are not a substitute for a rated shackle or a forged connecting link in a lifting assembly.
