Abstract

This invention is directed to a novel door frame assembly. More particularly, this invention is directed to a pre-fabricated door frame assembly, the components of which are adjustable and such that the assembly can be used for either right hand or left hand doors and can fit a wide variety of widths and heights of door openings through walls of various thicknesses. The invention includes a slide guide unit, two of which in interlocking combination are suitable for use in constructing an adjustable width jamb as part of a pre-fabricated door frame assembly, comprising: (a) a generally broad body having therein along one side thereof a V-shaped groove extending substantially the length of the body; (b) a first V-profile tab located at the same side of the body as the V-shaped groove, extending from the body in a direction away from the V-shaped groove, and in a plane generally aligned with the plane of the body and the V-shaped groove, the dimension of the V of the first V-shaped tab being generally commensurate with the dimension of the interior of the V-shaped groove; and (c) a second V-profile tab positioned on the same side of the body as the first V-profile tab, and in general alignment with the first V-profile tab extending in generally the same direction as the first V-profile tab, the dimension of the V of the second V-profile tab being generally commensurate with the dimension of the exterior of the V-shaped groove.
