In architecture and joinery, the chambranle is the border, frame, or ornament, made of stone or wood, that is a component of the three sides round chamber doors, large windows, and chimneys. When a chambranle is plain and without mouldings, it is called a band, case, or frame. The chambranle consists of three parts; the two sides, called montants, or ports, and the top, called the traverse or supercilium. The chambranle of an ordinary door is frequently called a doorcase; of a window, window frame; and of a chimney, manteltree.
