A pivot latch adapted for releasably securing a pivotable sash window to a master frame. The master frame has opposed, vertically extending guide rails. The sash has a hollow top sash rail, a base and a pair of hollow stiles cooperatively connected together at adjacent extremities thereof to form a rectangular sash frame. The top sash rail includes a pair of opposing header slots. Each of the header slots forms a pair of opposing, longitudinal header rails. The pivot latch comprises a housing having an outward end opening. A latch bolt is disposed within the housing. The pivot latch further includes a spring for biasing the latch bolt outwardly through the outward end opening and is adapted for engaging one of the guide rails. The housing has a cover having longitudinal edges and a pair of side walls depending from the cover and disposed inward of the edges. Each of the side walls has a side wall rail which cooperates with a respective one of the housing cover edges to form a longitudinal groove adapted to cooperatively receive a respective pair of the header rails. A tab depending from the housing is provided for engaging a respective one of the stiles to retain the tilt latch in position. A method of manufacturing a pivotable sash window including such a pivot latch is also disclosed.
