Pair of Fluted Crystal Door Knobs in Antique-By-Hand

Delicate crystal knobs paired with slim and stylish Art Deco plates were all the rage in the 1930s. Cheerful, bright and beautiful, they are just as appealing today. These top-quality reproductions come with a forged brass base in an array of classic finishes.

Dimensions:
Knobs: 2" diameter
Shank: 19/32" diameter, drilled for a 20 TPI spindle
Spindle: 3 1/2" L x 9/32" thick".
Fastener/s: #8-32 x 1/4" set screws and a hex key

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.
