Abstract
A window including a sash assembly having a combination support and screw attachment bar for use with a plastic box-like girder is disclosed. The structural support fits within the plastic girder to provide additional structural rigidity and includes an extension portion adapted to receive a fastening means for providing a secure fastening arrangement for a window latch or other apparatus. The identical structural support may be used in other portions of the window to provide additional structural strength adjacent a lift bar portion for manually manipulating a sash assembly.References Cited
