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 backplate. The fluting on the 2 inch (50 mm) diameter glass knob sets off the fashionable 4 1/2 inch by 2 1/4 inch backplate, blending form, style and function. It is a throwback to another spectacular era but fits a modern door 2 1/8 bore hole. Pictured in polished brass, the door knob is also made with polished chrome, antique brass, brushed nickel, and oil rubbed bronze. The dummy door knob is a fixed knob with double rosettes and is commonly used on French-style or bi-fold doors. Single sided and double sided dummy options can be used with or without a borehole, if no borehole is present countersinking may be required. This style is available as a single sided dummy knob (1 fixed knob), double sided dummy knob (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 latch, or you can request a 2 3/4 inch back set at no extra charge.
