Patent abstract
A tilt latch for pivotable window sashes is preferably integrally molded from a durable polymeric material but can also be made from metals, metal alloys or the like. The latch includes an angled projection for engaging a recess in the window frame and includes a central body having a cavity for containing a coil spring. Upper and lower covers overhang the sides of the body to form channels for engaging the edge of the sash groove.
