Door Selectors

The door selector ensures that a pair of self-closing fire doors with rebate-style meeting door frames or safety astragalus will always automatically close in the correct order, no matter which door opens first. 
The Fire Door Coordinator has surface mounted rebates so it won't damage the fire door frame structure and can be used with any door material.
This Fire Door Selector ensures that the doors do not erroneously overlap after the pair is closed. This is especially important for fire doors and self-locking security doors, as it keeps the door sealed.
