Abstract: A latch for use in window constructions, particularly vertically and horizontally sliding window constructions. The latch is generally mounted internally in a window sash frame so that its latch bolt protrudes from the sash to engage a guide slot in the main frame jamb or header of a window frame. The latch includes a thin rectangular base plate having upstanding bosses on its opposing ends which are pierced by vertical bores that pass through the base plate. The latch bolt is of substantially the same width as the base plate and slides over it.
