Abstract: A door frame has hinge and latch jambs extending from opposite ends of a header jamb. Each jamb has an inside section for extending into a doorway opening in a wall and having a molding section extending laterally outwardly from the respective inside section for overlying a face of the wall adjacent the doorway opening. Each molding section includes an inner end extending from the inside section, an outer face extending generally perpendicularly from the inner end and an outer free end extending generally perpendicularly from the outer face. A jamb securing and sealing flange is joined to a jamb. The flange has first and second end sections coupled by a centered section. The first second is substantially parallel to and affix to a inner surface of the outer face of one jamb. The second end section extends substantially parallel to the first end section and laterally outwardly beyond its outer free end.

Abstract: A coupling for mounting a door frame in an opening in a wall includes two, substantially identical anchoring clips and two substantially identical retaining clips. Each anchoring clip has a base mounting portion and a resilient cantilever portion extending at an non-perpendicular angle from its base mounting portion. The anchor clips are oriented opposite to one another. Each retaining clip has a base mounting section and an angled section extending in an cantilever manner from its base mounting section. The retaining clips are oriented mirror image such that the cantilever portions of the anchoring clips engage the angled sections of the retaining clips.
