ABSTRACT:
A door frame is prefabricated at remote construction sites and is installed into wall openings without requiring substantial on-site fittings, moldings, trims, and attachments. The door frame includes a header jamb and header grooves. A header scribe strip is fitted to and disposed in one of the header grooves. Header spring means are disposed in said header groove and are pressing the header scribe strip outwardly. Header plate means are pivotally attached to the side of the frame facing the opening face of the wall opening and disposed such as to assume a first locking position. A first and a second side jamb each have a first end attached to the header jamb and have a first and a second side groove. A first side scribe strip and a second side scribe strip are in each case fitted to and disposed in one of the respective side grooves. First and second side spring means are disposed in each case in the respective side grooves and press the respective side scribe strip outwardly. First and second side plate means are pivotally attached to the respective side of the frame and disposed such as to assume a respective locking position. The respective side scribe strip is retained in the respective side groove such that the protruding side of the respective side scribe strip is about flush with the corresponding side of the frame.
