Abstract
A door frame employs extruded aluminum jamb moldings, including extruded jambs, or jamb cover moldings in combination with jamb substrates. The extruded aluminum molding includes a mounting fin kerf. The kerf is generally boot-shaped, having an inwardly-disposed foot portion and an opening having an ankle-shaped cross-section. The mounting fin can be generally rigid, such as an extruded aluminum fin or a generally rigid polymeric fin. The kerf, in combination with the mounting fin, which has a bulbous rigid base, facilitates locking the fin in an erect orientation at about 75 degrees to about 90 degrees relative to the jamb body or the jamb substrate. The kerf/fin combination further provides improved ease of release of the fin from the erect orientation and facilitates rotating/retracting the fin into contact with the jamb body or jamb substrate.
