    摘要: A counterbalance system for an upward acting door including a first casing and a second casing. Each casing includes a spring element disposed therein operable to store and release potential energy in response to movement of the upward acting door between open and closed positions. The first casing is interlockable with the second casing to accommodate and counterbalance upward acting doors of differing weights.
