WINDOW BALANCE SYSTEMS
A window balance system includes a U-shaped channel with a first end and an opposite second end, and a balance element supported within the U-shaped channel. The balance element includes a fixed pulley block coupled to the first end of the U-shaped channel, a movable pulley block movably disposed in the U-shaped channel, and a cord extending between the fixed pulley block and the moveable pulley block. The window balance system includes a locking device coupled to the fixed pulley block and configured to engage with the cord and lock a position of the fixed pulley block with respect to the cord. The window balance system also includes a shoe coupled to the second end of the U-shaped channel. The shoe includes an elongate portion and an enlarged portion such that the shoe is substantially T-shaped, and a chamber configured to receive at least a portion of a pivot bar.
