Exit device force adjustment mechanisms
A force adjustment mechanism configured for use with an exit device including a pushbar having an extended position and a retracted position. With the pushbar in the extended position, the pushbar resists movement toward the retracted position with a net resistive force. The force adjustment mechanism is operable to adjust the net resistive force.
