Find replacement knobs for grand and upright music desks and fallboards, offered in a range of materials and finishes to match existing hardware, including solid bright or satin brass, antique bronze, and wood. Choose from threaded styles that mount with machine screws or peg-end designs commonly found on older uprights that press-fit into existing holes. Most options are sold in pairs for left and right sides. When selecting, measure your current knob head diameter and projection, confirm the post type, and check the hole or thread size on your piano to ensure a proper fit. These knobs provide a straightforward way to restore function and appearance to the music desk or fallboard while maintaining the instrument’s original look.
