Abstract
Abstract A snap-in jamb anchor comprising a right angular bracket having a horizontal wedging plate arranged to establish a wedge-type friction fit with the interior surface of channel-shaped sheet metal doorjambs at opposite sides to provide a connection between the horizontal girder of a building and the jambs, thereby to support the doorframe within an opening of a sheet metal wall. Jamb extensions may be secured to a vertical flange of each jamb anchor and extend upwardly above the header of the doorframe to a roof girder which is located above the header so as to act in combination with the jamb anchors in stabilizing the upper portion of the metal doorframe within its opening.
