The form of the No 1160 knob takes inspiration from nature by maintaining organic lines reminiscent of the tulip flower. The shallow dome of the face is circumscribed by a dual astragal. The rosette continues its organic form by flaring at the base of the shank into a astragal and step. Although shown here with exposed fasteners, a round rose with concealed fasteners can also be provided. Full mortise entry locks, privacy locks, passage latches, as well as tubular latches can be provided for use with this knob. All Nanz plated and patinated finishes are available.
