ABSTRACT:
A counterbalance system for a tilt-in window that has tilt post brackets. The tilt post brackets selectively mount to the vertical side elements of a window sash. Accordingly, the tilt post brackets need not be manufactured into the structure of the sash. Each tilt post bracket has a vertical section that mounts directly with the vertical side elements of the window sash frame. A brake element extends from the vertical section, therein providing the window sash with a tilt-in pivot post. The brake element provides both a braking system and a curl spring support structure.
