23 ABSTRACT A device for fine adjustment of sashes in a double-hung sash assembly of the type comprising four movable sashes linked two by two by a set of two cables located on each side of the window frame and supported by four pulleys. At least two pulleys, and preferably four, are operatively attached to a support slidably mounted in a vertical rail provided in a housing. Each support is moved by means of a screw for adjusting relative positions of sashes, each screw comprising an upper end abutting on or operatively attached to one of the supports, an intermediary portion meshed to an element integral with the housing and a lower end downwardly projecting from the housing and preferably operable with a screwdriver. It allows fine adjustment of the relative position of a pair of sashes linked together to thus allow them to close simultaneously.
