What tool is specifically designed to grip large metal pipes in inaccessible areas?

The chain wrench is specifically designed to grip large metal pipes, especially when those pipes are in inaccessible areas. This tool features a chain that wraps around the pipe and is attached to a handle. When the handle is turned, it tightens the chain around the pipe, providing a secure grip that allows for effective turning or holding of the pipe without slipping.

This makes the chain wrench particularly useful in situations where there is limited space to maneuver a traditional wrench or pipe tool, allowing users to work on pipes that are positioned in tight or awkward locations. Its design caters to larger diameters and is essential for plumbing and automotive tasks where robust grip is necessary.
