T-top

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.

The removable panel roof was patented by Gordon Buehrig on June 5, 1951.

[1] It was first used in a 1948 prototype by The American Sportscar Company or “Tasco.”[2] The 1968 Chevrolet Corvette coupe was the first U.S.-built production automobile to feature a T-top roof.

[citation needed] Post-C3 models were built with a targa top instead of a T-top.
