Schaub Siena vibra nickel knob is a 1-3/8 inch (35 mm) round cabinet knob from the Siena collection by Schaub and Company, so it delivers a consistent look across projects that use this line of decorative hardware. The knob is made from zinc die cast, which provides a solid feel in hand while keeping weight manageable for standard cabinet doors and drawers. Its vibra nickel finish gives the hardware a muted nickel appearance, which helps it blend with many nickel-toned hinges and pulls on the same run. The knob diameter is 1-1/2 inches, giving fingers enough contact area for reliable grip on everyday openings. A base diameter of 3/4 inch keeps the footprint compact, which helps when laying out multiple knobs across smaller fronts or narrow rails.
The Schaub Siena Series vibra nickel 1-3/8 inch diameter knob uses an 8-32 thread, matching the specified screw size, which suits common cabinet door and drawer front drilling prepared for 8-32 hardware. The knob projects 1-1/8 inches from the cabinet surface, so the hand clears most door edge profiles while pulling straight out. With a 1-1/2 inch overall diameter, the knob centers easily on standard 1-3/4 inch or wider stiles without crowding panel details. The 3/4 inch base diameter defines the bearing surface against the wood, which helps when laying out knobs near edge profiles where flat landing area is limited.
The Schaub Siena Series vibra nickel 1-3/8 inch diameter knob is part of the Siena collection, so it is suited to projects where that collection is used as the visual standard across a room or bank of cabinets. Its 1-1/2 inch diameter allows the knob to sit comfortably on typical kitchen cabinet doors, bathroom vanities, and built-in storage fronts without overpowering the face. The 3/4 inch base diameter keeps the footprint compact, which helps when placing the knob on narrow drawer fronts or door rails that carry panel details or edge profiles close to the mounting point. The 1-1/8 inch projection gives doors enough stand-off to avoid fingers rubbing the finish during pulls, which is useful on heavier doors that are opened many times per day.
The defined 8-32 thread size for this Schaub 250-VN cabinet knob aligns with a common cabinet knob standard, which simplifies drilling patterns and hardware choice across a full job when using other 8-32 threaded pieces. The 1-1/2 inch diameter and 1-1/8 inch projection work together to give a predictable reach and hand feel from one door or drawer to the next, which supports consistent user experience on long cabinet runs. The 3/4 inch base diameter also creates a clear visual boundary around the knob, which helps installers sight straight lines along doors and drawers because the base edge is easy to align to layout marks. The vibra nickel finish specified in the description ties directly to Vibra Nickel, which lets designers match finish names accurately when pairing this knob with hinges or pulls described with the same finish.
