Abstract: A prefabricated door frame includes two vertical frame elements and a header element, each of channel shaped configuration with side flanges encompassing the wall at the edges of a wall opening. One of the vertical frame elements is secured by the aid of threaded fasteners passing through the jamb face of the frame element and into the rough frame member. Heads of the fasteners prevent movement of the frame element away from the rough frame member. After appropriate adjustment to plumb the frame element, cover plates are attached to the jamb face and overlie the screw heads thus to secure the frame element in its adjusted position. The header and other vertical frame element are positioned by the aid of registry clips inserted at the ends of the header element and the upper ends of the vertical frame elements.

Abstract: A molding for drywall panels or the like has a channel to provide a reveal. To provide selected finish or color, a trim structure is provided that likewise has a channel configuration. The side walls of the trim structure and the side walls of the molding provide a sawtooth and rib structure for snap connection. The ends of the trim channel sides provide laterally outwardly extending lips to overly the end edges of the molding. The trim conceals all plaster splashings, obviating cleaning, provides selected color or finish. The desirable reveal characateristic is retained by virtue of the fact that the trim structure itself is a channel.
