Gravity Door Coordinator
The Ives COR7G has been around for at least 50 years. In the old days before electrically activated door closers fire doors would have fusible link armed door closers. When the lnk melted, the door closed, and if there was not a mullion between door, they would use this style of door coordinator so the door with the astragal would close first.
When active door is open, coordinator prevents active door from closing until inactive door bypasses. 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.
Gravity action arm and door bracket are adjustable on the job for ease of installation. Rubber roller provides quiet and efficient operation, and helps protect the astragal and doors from damage. Nylon roller on short arm glides smoothly over door bracket and strike, ensuring silent operation. Made of forged brass.
COR7G-26D for use on pairs of doors with astragal on active door up to 4' or with astragal on inactive door up to 3'4" or with astragal on both doors up to 2'10" Brushed Chrome Finish.
