Reclaimed purple door knobs. Virtually the same as our popular cut glass knobs the purple knobs have been in the sun for the last 80 years and due to a high Magnesium content in the glass they achieve a purple hue. Usually found on exterior French doors and entry doors. Rescued from various old houses along the east coast. Many available. Each and every knob is unique and “one of a kind”. We test all knobs to make sure they are fit for another lifetime and beyond. Each set or pair consists of two knobs, spindle, and set screws. These are a rare find so supplies are fairly limited.
