Abstract

A snap lock balance shoe of a balance system may be incorporated in pivotable double hung windows. In one embodiment, the snap lock balance shoe includes a pair of retractable tabs that partially extend through openings within an inverted window balance channel. The shoe includes a locking member that extends toward a window jamb when a cam of the shoe is rotated. This extension locks the balance system in place in the window jamb.
