An operator for a French casement window having an operating arm with a roller mounted at its end and pivotable to move in an arc between extended and retracted positions, and a channel member horizontally mountable on the inner side of one sash and confining the roller as the operating arm is moved between its extended and retracted positions to move one between open and closed positions, respectively. A bracket is on the inner side of the other sash adjacent its outer vertical side, and a drag link is pivotally connected on one end to the bracket and on the other end to the operating arm to move the other sash between open and closed positions synchronously with the first sash when the operating arm is moved between its extended and retracted positions, respectively. The drag link may be selectively in or out of alignment with the operating arm pivot axis when the sashes are in their closed position, whereby one sash is closed slightly ahead of the other when the sashes are moved to their closed position and the other sash is moved slightly ahead of the one sash when the sashes are moved from their closed position toward their open position. A sealing flange along the middle vertical side of the one sash sealingly engages the inner side of the other sash, and a second sealing flange along the middle vertical side of the other engages the outer side of the one sash, when the sashes are in their closed position.
