ABSTRACT:
A sash balance brake and pivot pin assembly for a sash window which maintains the window substantially square prior to installation is disclosed. The pivot pin extends outwardly from the window sash. The sash balance brake is disposed within a track in the window frame and includes a cam rotatably disposed within an expandable housing. The pivot pin has a collar for lateral engagement with the cam to prevent the window frame from bowing away from the window sash, thereby maintaining the window frame substantially square.
