What is changing inside the Von Duprin 22 model to allow for QEL/HD-QEL feature?

The mechanism case was made to "stop" the pushbar travel on the old model 22.  This "stopping" action was accomplished with an internal "seam" in the mechanism case.  This "seam" does NOT allow the QEL motor to fit inside the mechanism case.  This seam has been removed and pushbar "stops" have been added to the baseplate assembly.  Also, a dogging extension has been added to allow the motor to retract the latches for Rim/Vertical applications.
