ABSTRACT:
An improved casement window sash unit includes a pair of track and hinge assemblies, each being secured to one of the upper and lower horizontal window frame members of a window opening in a building. Each track and hinge assembly includes a track having a toggle hinge pivotally and slidably secured thereto and to the sash. The track for each assembly has a pair of elongate longitudinally extending openings therein, each accommodating an attachment screw therethrough, each opening being of a size to permit slight longitudinal shifting of the track relative to the window frame. Each track and hinge assembly includes a cam positioned within a cam opening in the track and secured to the track and window frame by an attachment screw. Each cam is selectively shiftable in either direction from a centered position to slightly shift the track longitudinally of the window frame before the attachment screws are tightened to adjust the position of the hinge relative to the window frame and thereby overcome sash sag.
