Made for modern doors - Victorian hardware and furniture is characterized by a blending of different styles that range from simple to elaborate. This door knob captures that style by combining the beauty of a crystal clear glass knob that looks modern and retro at the same time, with an ornate Victorian back plate. The fluting on the 2 inch (50 mm) diameter glass knob sets off the fashionable 4 1/2 inch by 2 1/4 inch back plate, blending form, style and function. It is a throwback to another spectacular era but fits a modern door 2 1/8 bore hole. The dummy door knob is a fixed knob with double rosettes and is commonly used on French-style doors. The unit comes with a standard 2 3/8 inch backset, or you can request a 2 3/4 inch backset for no extra charge. The attractive door knob is available in polished brass, antique brass, oil rubbed bronze, brushed nickel and polished chrome. Choose the optional Locking feature for Bedrooms and Bathrooms. The set is also available in double dummy (2 fixed knobs), passage (non-locking) and privacy (locking) sets.
