ABSTRACT:
A window assembly has a frame with balance channels to opposite sides of the frame, balance devices in the channels and a sash which is both slideable and tiltable relative to the frame. Also provided is a sash tilt limit bar which has a first end attached to the sash and a second end which is held within and which slides vertically of one of the balance channels without interfering with the balance device in the channel. The bar limits the tilting of the sash to positions which do not allow the second end of the bar to travel sufficiently far as to allow the bar to move to a position perpendicular to the frame where the bar might otherwise block closing of the sash.
