ABSTRACT:
A metallic frame and the assembly from which it is constructed has a header and a jamb and a means to attach them together at a corner of the metal frame. The header and the jamb each have a soffit disposed inwardly from a rabbet and a stop extending substantially perpendicular to and between the rabbet and the soffit. One of either the header or jamb has terminal ends of a first soffit, a first stop, and a first rabbet that generally lie in the same plane with a first corner edge. A rail slot extends through a width of the corresponding first stop and thicknesses of the first soffit and the first rabbet. The other of the header and a jambs has track formed along a second rabbet between a terminal end of a second rabbet and a terminal end of a second stop and second soffit which are cut back and spaced a distance from the terminal end of the second rabbet such that the track and the rail slot are slidingly engageable.
