While generally employed in the most public areas of recent projects, the No 1017 comes from the most functional of all designs. Often referred to as back of house, this knob found its origins in service areas and equipment rooms. Its companion lever, the No 2017, has a similar pedigree. The design of the No 1017 knob, dating to the early 20th Century, eliminates surface ornament and emphasizes the functional properties of the handle. A slight step joins the handle to the straight shank, which is met by a round-edged rose with three exposed screws. The resulting design is both classic and modern. The knob has a diameter of 2-1/4″ with a projection of 2-3/8”. Full mortise entry locks, privacy locks, passage latches and tubular latches may be provided for use with this knob. The handle is available in all Nanz finishes and may be paired with a variety of exposed-screw rose designs. A selection of related products is also available.
