The glass is carefully set into a handsome brass base with a threaded shank in the back. It also comes with a 8-32 thread truss head screw which allows for mounting the knob from the back. Add some sophistication & flair to your cabinets with these beautiful & colorful pieces! Use only hand tools to install glass knobs on your cabinets. Power tools (or even wrenches) may cause damage to the thread or to the knobs. Carefully hand-install the knob by using a hand screwdriver by fastening the screw into the knob. When installing, do not turn the knob itself as it may cause breakage. Tighten carefully but do not over-tighten – remember they are made of glass & are by their nature, fragile. We will not replace broken knobs due to over tightening or mishandling.
