Abstract: This apparatus uses cladding to cover the inner surfaces of a door frame. The cladding also overlaps the door nose and its mounting screws. Two-sided adhesive tape on one edge of the cladding attaches the cladding to the door nose. The cladding has a perpendicular integral fin which extends into an opposed mating slit parallel to the door frame edge in the door frame inner surface. This combination aligns the cladding parallel to the door frame and holds theh cladding in place against tangential forces. An outwardly extending groove from the edge of the door frame opposite the door nose and parallel to the edge terminates in a keyway. The edge of the cladding opposite the nose has an perpendicular inset, which is sized to fit within the groove in the door frame. The inset terminates in an inwardly directed projecting key. The end of this key is pointed to engage the door frame keyway to hold that edge of the cladding securely in place.
