The present invention relates to a door frame, particularly a door frame for a pre-hung door assembly, which is foldable to minimize storage space and to allow for enhanced logistic efficiencies. The door frame contains parallel, spaced apart, vertical jambs and a horizontal header connecting the top ends of the jambs. Each of the jambs and the horizontal header contains a front section and back section that are hingedly joined so that then can be folded on to each other. The hingedly joined front and back sections allow the door fame to be foldable to minimize space occupied during storage.

Devices and methods for mounting door frames

A door unit in kit form includes a partially preassembled split doorjamb assembly, a door, and extensions. The partially preassembled split doorjamb assembly includes first and second side bases substantially parallel to one another and a header base substantially perpendicular to and interconnecting the first and second side bases. The door is arranged within a space defined by the first and second side bases and the header base of the partially preassembled split doorjamb assembly so that the door, the first and second side bases, and the header base collectively establish a cavity. The first and second side extensions and a header extension are unassembled with respect to and connectable lengthwise to the first and second side bases and the header base, respectively. The extensions may be stowed within the cavity and/or stored on outer surfaces of the bases.
