Pair of Black Porcelain Rim Lock Knobs with Black Iron Shanks - 1 3/4" Diameter

These lustrous black porcelain knobs are a stately companion to any Victorian iron rim lock. With their small diameter, these knobs are ideal for use with narrow backset rim locks typically used on French and screen doors. The matte black powder-coated shanks are rust resistant for long-lasting wear.

Dimensions. Porcelain Knobs: 1 3/4" diameter. Long shank: 5/8" diameter, drilled for a 20 TPI spindle. Spindle: 4" L x 9/32". Includes Allen wrench and set screw.

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.
