Stamped Brass New York Privacy Back Plate With Thumb Turn In Antique-By-Hand Finish

This New York style back plate is designed for the interior side of a bedroom or bathroom door. It features a classic crescent thumb to activate the privacy mortise lock from inside the room. Made of solid, wrought brass in our living antique finish.

Dimensions: 7" H x 2 1/4" W. Inside collar diameter: 5/8". Center to center spacing from thumbturn to knob collar: 2 1/4". Thumbturn spindle: 3/16" x 1 5/8"; oriented on the diamond.

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.
