The enduring beauty of P. & F. Corbin's Lorraine pattern door set makes this a wonderful choice for your new or vintage home. Their circa 1905 design is faithfully reproduced in stamped bronze for exceptional detail and given a rich, chocolaty finish with lustrous copper highlights - just like the antique originals. To complete the authentic look, the matching bronze knobs are mounted to a non-threaded, tapped spindle with slotted set screws. A traditional mortise lock with two skeleton keys completes the set.Door set dimensions: Doorknobs measure 2 1/4" in diameter.
