Kate makes this style of knob in the same manner as the Original Knobs. After the glass has been cut and sandblasted, she layers the glass with a fun and funky piece of glass on the top, before they are fused together in the kiln.
The hardware is a die-cast satin nickel base, 16mm dia. X 16 mm tall. The base is threaded for a standard 8-32 knob screw to a depth of 1/4″. All knobs come with an 8/32 break off screw that snaps to 1″, 1-1/4″, 1-1/2″.
