This small porcelain knob is unique in that it has the built-in bolt. The bolt is 1 1/4 inches long and, thus, could be used on a fairly thick drawer or door.
The knob measures 1/2 inch in diameter and projects 3/4 inch from the surface. Because of its age, there is slight crazing in the porcelain.
The knob is in very good condition with no chips or cracks. The original nut is included.
