Pair of Bennington Style Door Knobs With Antique Iron Shanks

The Bennington pottery first produced richly swirled clay knobs in the mid 1800s. 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 iron shank in antique iron 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.
