ABSTRACT:
In order to rigidify a doorway structure, one or more fixed doorway panels are anchored at their tops, bottoms and along one vertical edge in the case of an endmost fixed doorway panel. A swinging door is hinged to the other vertical edge of the one or more fixed doorway panels by hinges which carry lateral flanges on corresponding leaves receiving additional diagonal anchor screws which penetrate an adjacent stile to further rigidify the swinging door in its relationship to the fixed doorway panel on which it is mounted.
