BK-158 is a small, cast brass knob with a polished finish. This knob measures 5/8" in diameter and mounts through the back of the drawer or door with the included screw. This style knob was commonly used on lawyers bookcases or stacking bookcases. Also works well on jewelry cases as well as small desk drawers. This polished brass knob is based on styles seen frequently in the late 19th and early 20th centuries.
