The brace includes an elongated and generally horizontal arm to which is joined a vertical bar. The bar is adapted to be inserted into and wedged in a channel in a window side jamb and, when so inserted, holds the arm in a generally horizontal position. When a window sash is tilted downwardly and inwardly for washing, the brace supports the sash and prevents the sash from swinging beyond the wash position.
