Very unique Dark Aqua glass knob This Dark Aqua knob is 2 5/8" high by 2 5/8" wide the smooth pin hole is a whopping 1 1/8" in diameter it could be that this knob is unlisted insulator because it is larger than the CD 1110. The color is DARK AQUA and as a point of interest it has a great under pour on one end. And the best part is that I see nothing wrong with it.
