The No 1538 drum knob is a synthesis of traditional Georgian forms. It has a slightly domed face. 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. Full mortise entry locks, privacy locks, passage latches and tubular latches may be provided for use with this knob. It measures 2-3/4″ in diameter with a projection of 2-5/8”. The diameter of the rose is 2-3/4”. All Nanz plated and patinated finishes are available.
