What different types of door coordinators are available?
There are 2 types of door coordinators available:
Bar Coordinators (Ives COR Series):
Surface mounted to the bottom surface of the frame soffit.
The active door lever, located nearest to the active stop, holds the active door open until the trigger mechanism is released by the closing of the inactive leaf.
Gravity Coordinators (COR7G and COR9G Series):
Surface mounted on the face of the frame head and on the pull side of the opening.
When active door is open, coordinator prevents active door from closing until inactive door closes. Closing of inactive door causes strike plate on top of door to contact cam and lift arm, allowing active door to close. As inactive door continues closing, roller rides over strike plate on to door bracket, holding arm above active door.
