Stanley butt markers are used to mark the correct hinge size and mortise depth for residential door hinges. They can also be used to mark square corners.
***You'll use your butt marker when you install butt hinges. A butt hinge rests in a recess routed into the wood so that the face of the installed hinge sits flush with the surface of the door and the door jamb, as you see above. You want to rout that hinge recess carefully, neatly.
