Easiest and most perfect way for us to frame in double stacked windows. Because our windows are framed after the walls are installed, it’s a little bit trickier to make sure they are aligned.

Yes a level could work, but not as accurately or quickly in my opinion. These little plumb dot, line lasers are super handy! Do you use one in your job
