    Abstract: A snap lock balance shoe and system to 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. Embodiments of methods for installing the system include inserting a frame of the balance shoe within a jamb track of the window jamb, rotating the frame 90 degrees about a first axis, and rotating the frame 90 degrees about a second axis such that the frame is substantially fully disposed within the jamb track.

    Abstract: In a block and tackle window balance, the balance shoe holds and upwardly biases the terminal connector in a mounted position. A biasing element of the shoe maintains the terminal connector in a pocket of the shoe during operation of the balance. The terminal connector is prevented from laterally exiting the pocket in the mounted position by a widened portion on the terminal connector and a locating surface extending from the shoe toward the pocket. Manually pressing down on the biasing element or the terminal connector itself to lower the terminal connector in the pocket until the widened portion clears the locating surface allows lateral removal of the terminal connector from the pocket. During operation of the balance, however, the terminal connector does not experience a sufficient downward force to overcome the upward bias such that the widened portion never clears the locating surface.
