Round tops are a type of furniture knob or finial that features a rounded or dome-shaped top. They are commonly used in cabinet and drawer hardware as a decorative accent piece. There are several synonyms for round tops including ball knobs, dome knobs, round knobs, and spherical knobs. Each of these terms describes the rounded shape of the knob or finial, but with slight variations in the design. Ball knobs are typically smaller and more compact, while dome knobs have a more pronounced round shape. Round knobs and spherical knobs are more general terms that encompass any knob with a circular top. Regardless of the terminology used, round tops add a touch of elegance and sophistication to any piece of furniture.
