Meadows Design Forged-Brass Back Plate with Keyhole in Antique-By-Hand

This lovely classical style back plate was inspired by P. & F. Corbin's "Como" pattern of 1905. The delicate beaded design, originally produced in stamped brass or copper, is reproduced in top-quality forged brass. It comes in our exclusive Antique-By-Hand, a living finish that ages gracefully over time into a beautiful natural patina. At 2 1/2" wide, it works on pre-drilled doors and with vintage mortise locks. Complete the look with the matching beaded knobs (R-01NW-712733-ABH)!

Dimensions: 7 3/4" H x 2 1/2" W. Inside collar diameter: 5/8". Center to center spacing of keyhole to knob collar: 2 1/4".

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.
