ABSTRACT:
The present invention is a prefabricated door frame assembly with improved characteristics which includes a frame member formed of a web with flanges extending from its lateral edges. The web includes a pair of grooves opening in a common transverse direction, one groove located near the center of the web and the other groove located proximate one lateral edge of the web, and a longitudinally extending recess between the grooves. In combination with the web, the assembly includes at least two hinge members, each having a hinge plate including a set of elongate tongues adapted to engage and mate with the respective grooves in the frame member and a separate elongate tongue projecting normal to the other tongues into the recess of the frame member. Also included are at least two bars slidable in the recess of the frame member, each bar defining a longitudinally extending slot on its outer surface to engage the separate elongate tongue of its respective hinge member. Usually, the assembly includes a strike plate having elongate tongues similar to those of the hinge plates and a third such bar to engage the separate elongate tongue of the strike plate.
