What is a characteristic feature of a chain wrench?

A chain wrench is specifically designed to grip and turn objects that have a larger diameter, such as pipes or fittings. One of its defining features is its adjustable size, which allows it to accommodate various diameters of the materials it is intended to grip. This adaptability is particularly useful in mechanical and plumbing applications, where the size of the object may vary significantly.

The mechanism of a chain wrench comprises a chain that wraps around the object and tightens as you turn the handle, providing a secure grip that is essential for applying torque without slipping. Adjustable sizing facilitates the use of a single tool across different tasks, making it a versatile choice for users.
