Abstract:
1. A method for installing an inverted window balance system within a window jamb in a window frame comprising the steps of: providing an inverted window balance system comprising: inserting the inverted window balance system within a jamb track of the window jamb such that an axis extending along a longitudinal direction of the U-shaped channel is perpendicular to a back wall of the jamb track and an axis that is perpendicular to the two frame edge surfaces is parallel to the back wall while the frame front surface faces a side wall of the jamb track; rotating the inverted window balance system within the jamb track 90 degrees about the axis extending along the longitudinal direction of the U-shaped channel such that the frame front surface faces down; and rotating the inverted window balance system 90 degrees about the axis that is perpendicular to the two frame edge surfaces such that the frame bottom surface faces in a downward direction.
