Keyed removable Mullion 9310-689 Non-Fire Rated

The PDQ 9310 Series Keyed Removable Mullion is a heavy-duty architectural solution for double door openings requiring maximum security with temporary unobstructed access. Standing 120 inches (10 feet) tall, it provides a rigid center strike post for PDQ 6300 and 6400 Series Rim Exit Devices, making it ideal for hospital corridors, school loading zones, and convention centers where large machinery, gurneys, or palletized freight must pass through regularly.

Designed for efficiency, the 9300 eliminates the need for manual unbolting. A standard rim cylinder key allows the mullion to be removed from the top bracket in seconds. Once reinstalled, it automatically self-locks into the head bracket without a key, immediately securing the opening and restoring full fire and panic exit hardware functionality.
