Abstract
A constant force window balance system includes a mounting bracket defining a longitudinal axis, a coil spring, and a shoe. The shoe includes a first arm having a first inner surface and a second arm having a second inner surface. The shoe also includes a member extending between the first arm and the second arm. An opening is defined between the first inner surface, the second inner surface, and the member. The opening is configured to removably receive a portion of a pivot bar. The shoe is moveable between a locked position that prevents movement of the shoe along the longitudinal axis, when the pivot bar is not received within the opening, and an unlocked position that allows movement of the shoe along the longitudinal axis, when the pivot bar is received within the opening.
