A T-top (UK: T-bar) is an automobile roof with a removable panel on each side of a rigid bar running from the center of one structural bar between pillars to the center of the next structural bar. The panels of a traditional T-top are usually made of auto grade safety glass (tempered or laminated), or acrylic – but they can also be black or body-colored and made of other (often light-weight) materials.
