Great for use with our interior rim locks.

1 7/8" diameter

5/8” ferrule

These knobs are used on small doors, french doors, and with our narrow rim lock.  Bennington or mineral doorknobs were made in Vermont by swirling three colors of clay and then firing the knobs in an oven. Ours are made just like the originals.  Matte black finish on the cast iron ferrule.
