ABSTRACT:
The window assembly structure includes a control bar for limiting the extent of inward tilting of the sash commonly used for safe window cleaning. The control bar is forced to bend or distort during tilting of the sash producing a bias force that limits the amount of tilting. In a preferred structure the control bar is of a spring steel wire structure with various bent segments for effective and cost efficient securement of the control bar to the sash and frame.
