The No 13181 turned walnut knob is light yet strong and emphasizes a simple and natural aesthetic. Wooden knobs were produced in the 19th century, often in rosewood or maple, to add to the decorative effect of a room, though they lost favor as Modernism took hold in the 20th century. This knob combines the sumptuousness of its 19th-century predecessors with the clean lines of modern design. Full mortise entry locks, privacy locks, passage latches, as well as tubular latches can be provided for use with this knob. The knob is available in a variety of wood species and all Nanz finishes for the shank and rose, which can be chosen from a variety of designs. A minimum order is required for production.
