The No 1438 drum knob is a synthesis of traditional Georgian forms. A flat ring distinguishes the boss at the center from the ogival face of the knob. The drum-like shape, delineated by two astragals reflected across a cavetto profile, surmounts the contoured shank. The ogee and astragal motif is repeated in the round rose. The knob measures 2-3/4″ in diameter and has a projection of 2-3/4”. The diameter of the rose measures 2-3/4”. Full mortise entry locks, privacy locks, passage latches and tubular latches may be provided for use with this knob. All Nanz plated and patinated finishes are available.
