What type of pipe wrench is designed for turning and holding where marring is not objectionable?

The chain wrench is specifically designed for turning and holding objects without risking damage to the surface. It utilizes a flexible chain that wraps around the workpiece, allowing for a strong grip without the harsh jaws that traditional pipe wrenches employ. This feature makes it particularly advantageous when working with delicate materials or finishes where marring or scratching is not acceptable.

In contrast, the pipe wrench, while effective for gripping pipes, does so with serrated jaws that can mar or dent the surface. Similar to the pipe wrench, the adjustable wrench and crescent wrench also have metal jaws that can cause damage to surfaces when used, especially if a high amount of torque is applied. Thus, the chain wrench's design prioritizes surface preservation while still providing the necessary torque for turning and holding tasks.
