Title: Snap-in keeper for sliding windows, doors and the like

Abstract: A keeper element is shown for insertion in a sill extrusion in which the lower rail of a sash is movable. The keeper is a channel-like element with the terminal edge of one wall having interruptions for mating and interlocking with portions of the sill, such as spaced tabs adapted to extend into weep holes in the sill, or notches adapted to fit around internal sill projections. The keeper also has an upper surface confronting the lower rail in which a number of spaced openings are provided. A latch element is vertically slidable on a stile of the sash, and is adapted to be lowered so it extends into one of the openings in the keeper. In this manner, the sash is releasably locked in any of a plurality of positions, with security maintained because the keeper is locked against movement relative to the sill.
