Astragal

An astragal is a moulding profile composed of a half-round surface surrounded by two flat planes (fillets). An astragal is sometimes referred to as a miniature torus. It can be an architectural element used at the top or base of a column, but is also employed as a framing device on furniture and woodwork. The word "astragal" comes from the Greek and Latin for "vertebra," and the original astragals used in architecture were made in a beaded design, thereby resembling a vertebra.
