The picture does not give this door knob a true likeness. It is actually very dark in color, like walnut or ebony. We were amazed when we pulled this little guy out of a pile of miscellaneous door knobs. It was smaller, darker, and wood!
The knob measures 2 inches across and 3/4 inch deep. It is meant to be screwed onto a threaded spindle. A set screw is with the knob. Sure wish we had more than one!
