Pair of Black Porcelain Doorknobs with Brass Shank in Polished Brass

Jet black porcelain knobs are a Victorian era classic. Paired with small rosettes or back plates, they make a stately, yet understated period style door set. The durable glazed knobs are firmly fastened to a solid brass shank with a polished and lacquered finish.

Dimensions. Knobs: 2 3/8" diameter. Shank: 5/8" diameter, drilled for a 20 TPI spindle. Included spindle: 3 1/2" L x 9/32". Includes an Allen wrench and set screws for mounting knobs to spindle.

How do I know what door knobs will work with a particular rosette or door plate? The knob shank diameter should be a little less than the inside collar diameter on the rosette.
