Patent ID: 7716886

Claim:
A building fenestration comprising: a building panel structure having an opening bounded by surfaces facing toward the opening; a jamb positioned in the opening, the jamb having outwardly facing surfaces, the jamb configured to define a gap between the outwardly facing surfaces of the jamb and the surfaces of the building panel structure defining the opening; at least one bracket receiving slot on at least one of the outwardly facing planar surfaces of the jamb; and a bracket having first and second legs at a right angle to each other, the first leg of the bracket received in the bracket receiving slot, and the second leg of the bracket fastened to the building panel structure; wherein the bracket receiving slot is defined between one of the outwardly facing surfaces of the jamb and a substantially flat plate located entirely between corners of the outwardly facing surface of the jamb, the substantially flat plate being without features that project outwardly from the substantially flat plate, whereby the substantially flat plate may be integrally formed on the jamb or preinstalled on the jamb to provide a very low profile that will not interfere with packaging material or shipping procedures for pre-hung doors or pre-hung windows on which the substantially flat plate is provided.
