Jointing is the process of fitting a door into a frame. Wooden door frames should be constructed so that they can be installed plumb, level and square as well as the right size for the door and rough opening. In some cases, the rough opening may not be straight. This will require some adjustment to either the rough opening or frame to ensure the door will fit and operate correctly.
