Previously I used a monkey, but depending on the location I could not loosen depending on the thickness, but could be loosened easily with a single wrench. The monkey is versatile and versatile, but it will not work in places where width and thickness are limited, so it will be better to use a spanner. Since pipes are also hung, you can work with ease by applying torque.
I could use it without worry because there was no such thing as R to open even if I exercised a torque with my iron pipe extension. It was good to purchase because it was difficult to work with the handed double-ended wrench.
