ABSTRACT:
A door coordinator for controlling the closing sequence of a pair of double doors having a common line of closure. The coordinator has a biased trigger which pivots and a door stop which translates toward the rear of the coordinator upon triggering. Override is provided by an override block (preferably pivotally mounted) biased into a first position which moves to a second position upon application of more than threshold override force. With the override block in the second position, the door stop is free to move in translation to the rear of the coordinator and permit closure of the door even if the trigger is not depressed. Threshold override force is adjusted by a screw which adjusts the angular position of a base plate in contact with biasing springs which bias the override block.
