The Glass Door Knob Back to Back Mount is designed for frameless glass doors in showers, bathrooms, and other enclosures. This glass knob offers a functional grip on both sides of the door, making it easy to open and close while keeping a clean frameless look. Made from brass with an antique brass finish, this door knob coordinates with other glass handles, shower knobs, bath knobs, and glass pulls. The finish pairs with many bathroom styles and door hardware systems, giving a uniform appearance. The knob is designed for glass thickness from 3/16" to 1/2" (5 to 12mm), which is common for frameless glass installations. It has a 1" diameter with a 2-1/8" projection, providing a compact size that is easy to grip while fitting seamlessly on the glass panel. It requires a 3/8" or 1/2" hole size in the glass for mounting. The back to back mount style means one knob is placed inside and the other outside, connected through the glass, offering balanced handling from both sides. The set includes clear gaskets, which help protect the glass panel during installation and provide a snug fit. This makes the knob suitable for use as a pull knob, shower knob, glass pull, or glass handle in frameless bathroom setups. Can also be used as a robe hook, providing additional functionality in bathroom spaces.
