ABSTRACT:
An extruded door frame assembly comprising a pair of upright metal studs secured to the wall along opposite sides of the opening for the door a pair of extruded upright metal frame members or stiles secured to the metal studs, and an extruded metal cross-piece or lintel connected across the top of the door opening between the upright members or stiles. The metal studs include a laterally projecting flange which extends longitudinally for the length of the stud along a first side thereof. The extruded stiles include a longitudinal slot formed along the inner face of a corresponding first side wall, opening to receive the longitudinal flange of the respective stud to which the stiles are to be connected. An inner face portion adjacent the opposite second side wall of each stile includes a cam surface terminating at a longitudinal recess to receive therein a correspondingly shaped longitudinal projection along the opposite second side of each metal stud. The stile is pressed against the stud whereby its longitudinal projection slides along the cam surface of the stile, forcing the inner face portion to spread apart slightly until the longitudinal stud projection snaps into the longitudinal recess of the stile thereby securing the stile to the stud. The cross-piece includes corresponding slots, with metal clips to connect to the stiles. The stud flange on the hinge side is flush with the end wall. The one on the strike side is stepped for space to mount the strike box.
