Channellock 812WCB Code Blue Adjustable Wide Wrench, 12-Inch

It looks high quality, it has a perfect grip in my hand and when I place the measurement I need to work it remains fixed without varying the initial measurement.

The best adjustable wrench I have used.

Smooth jaw movement, jaws align square, rubber handle is firmly attached. Large jaw capacity (~41mm)

Best thumb wrench you can buy same size has as 8” though

Extremely high quality tool. Opens past the 1 1/2 inch markings, to a full 1 5/8ths. Very precise thumb-roll adjustments, holds size very well, the moving jaw has very little play, and it opens so much wider than a normal 12" adjustable. The jaws are also long, and they taper slightly, which allows this thing to fit in tighter spaces. The big blue handle is very comfortable, you can really apply force without it digging into your hand. I also like that it is marked with the opening width on both sides (metric/sae) so you can pre-set the wrench pretty closely, or use the wrench to determine the exact size of a fastener. Worth every penny.
