Abstract
A removable balance system for a sash movable vertically between a pair of window jambs. The balance system includes a U-shaped balance channel member and a double block and tackle system disposed within the U-shaped balance channel with a locking feature selectively operable between extending laterally outwardly from the shoe for engagement with an opening in the jamb channel and recessed within the shoe. In operation the locking feature is inserted into an upper most opening in the jamb channel and the cord of the double block and tackle is withdrawn to an extent sufficient for the locking feature to engage a second opening in the jamb channel thereby securing the balance system in place within each jamb providing a seat for the sash atop the two laterally disposed shoes.
