Flat Disc Glass Knob Satin Brass describes a Schaub and Company knob from the City Lights collection that uses a flat glass disc design in a satin brass finish, giving cabinet and furniture fronts a clean, modern look that stands out visually. The 1-3/8 inch diameter disc size creates a comfortable grip area that is easy to grab, which helps on frequently used doors and drawers in a busy shop or home. The glass disc construction paired with the satin brass base gives a mixed-material look that reads higher end, which matters when matching existing decorative hardware or presenting finished work to demanding clients. The knob is identified by manufacturer part number 77-SB, so repeat orders or replacements can be matched exactly to earlier installations, avoiding mismatch or rework on multi-room or multi-unit projects.
The Web Description states that the thread size on this Flat Disc Glass Knob, Satin Brass, 1-3/8 inch dia is #8-32, giving installers a clear machine-thread standard to work with when mounting it through cabinet faces. Using a knob with a known #8-32 thread lets shop crews line up with the common tap pattern found in many cabinet and drawer hardware setups, which simplifies planning across banks of doors and drawers. The 1-3/8 inch diameter callout provides a predictable edge clearance around the knob center, supporting precise drilling layouts in both new builds and replacement situations. Because the knob size and thread are clearly defined, it fits well into templated drilling jigs and repeatable workflows where every pull point needs to land consistently.
The SAP Description lists this part as CITY LIGHTS FLT DISC GLSS KNOB,1-3/8',SB, tying it directly to Schaub and Companys City Lights family for decorative hardware work. That family reference helps when this Flat Disc Glass Knob is used across coordinated spaces such as kitchens, baths, or built-ins, because the satin brass finish can be matched visually with other City Lights pieces specified on the same plan. The 1-3/8 inch diameter noted in the description sets a predictable scale that sits comfortably on standard cabinet doors and smaller drawer fronts, which matters for proportion when hardware is repeated dozens of times. As a glass knob under the Decorative Hardware & Moldings category, it suits cabinetry and furniture applications where the hardware contributes to the finished look as much as function.
