Characterized by its bold geometric shapes, vibrant colors, and stylized motifs, Art Deco represented a departure from the ornate styles of the past and embraced modernity, technology, and luxury. These door sets are surface mounted. The standard backset provided is 2 3/8 inches, with the option to substitute it with a 2 3/4 inch backset at no additional if requested at time of purchase. Our polished brass has a living finish, which means it naturally darkens and ages over time. If you order multiple pieces in polished brass, there might be slight variations in finish and tone initially. Other finishes won't darken or tarnish. For a lasting shiny polished brass finish, you can request a custom lacquered brass finish by emailing us. All measurements are approximate.
