An inverted window balance system comprising:
- a U-shaped channel comprising a plurality of openings;
- a spring connected to a system of pulleys located within the U-shaped channel;
- a cord with a first cord end and a second cord end, the first cord end connected and threaded through the system of pulleys, the second cord end connected to a jamb mounting attachment;
- and
- a balance shoe, wherein the balance shoe comprises:
- a frame;
- a locking member at least partially disposed within the frame;

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:
- a U-shaped channel with a plurality of openings;
- a spring connected to a system of pulleys located within the U-shaped channel;
- a cord with a first cord end and a second cord end, the first cord end connected and threaded through the system of pulleys, the second cord end connected to a jamb mounting attachment;
- and
- a balance shoe comprising:
- a frame comprising a frame bottom surface, a frame front surface and two frame edge surfaces;
- a locking member at least partially disposed within the frame;
- a cam in communication with the locking member;
- and
- a connecting device for attaching the balance shoe within the U-shaped channel;
- 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.
