Pair of Black Porcelain Rim Lock Door Knobs With Iron Shanks In Antique Iron

These lustrous black porcelain knobs are a stately companion to any Victorian iron rim lock. The solid Iron base is offered in antique iron. Each knob set has one long shank and one short shank with a flange (to sit flush on the lock surface).

Dimensions. Knobs: 2 3/8" diameter. Long shank: 5/8" diameter, drilled for a 20 TPI spindle. Spindle: 4 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.
