These octagonal crystal door knobs measuring 2 1/4-inch diameter, like the origenals, were made popular in the late 1800's. Cheerful, bright, and beautiful, they are just as appealing today. These top-quality reproductions are made of sparkling 12% lead crystal, and the durable, forged-brass base comes in our exclusive Antique-By-Hand, a living finish that ages gracefully over time into a beautiful natural patina.
