This is connected to the window by a sash cord or chain, which runs over a pulley at the top of the frame, although spring balances are sometimes used. Sash windows may be en suite with simplex hinges which allow the window to be locked into hinges on one side while the offset on the other site is detached, allowing the window to be opened for escape or cleaning.
