Made for modern doors - there are lots of ways to describe the Regency door knob – versatile, elegant, adaptable, and graceful. Perhaps that’s why the fluted doorknob design was so popular from the late 1800s to the early 1940s and keeps making a comeback. This particular 2 inch (50 mm) diameter fluted crystal clear doorknob has been matched with a simple 2 1/2 inch (63 mm) diameter Victorian rosette for a stylish design. There are two rosettes that screw into each other after placing them on opposite sides of the door. The model shown has an antique brass finish and is also available in polished brass, oil rubbed bronze, polished chrome and brushed nickel. The set is available in single dummy (1 fixed knob), double dummy (2 fixed knobs), functional passage (non-locking) and functional privacy (locking) sets. Functional door knobs come with a standard 2 3/8 inch back set, or you can request a 2 3/4 inch back set at no extra charge.
