This included intricate patterns, motifs, and detailing on various household items, including doorknobs sets. 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. To achieve a flush finish, your door needs to have a borehole. This product has a processing time of about 1 to 2 business days before it is shipped.
