When a window sash is installed into a window frame, it assumes an operable position where the vertical sides of the window sash are aligned with the side jambs of the window frame. When the sash is in its operational position, a gap space exists between each of the vertical sides of the window sash and the side jambs of the window frame. This gap space is utilized by a counterbalance system. Spacer assemblies are attached to the window sash. Each spacer assembly has a base that mounts to the window sash and a slide that selectively extends from the base. The slides are extended across the gap spaces between the sash and the side jambs. The slides are brought into close proximity with the side jambs. The presence of the slides prevents the window sash from being able to cock out of its intended operational orientation.
