PDQ 9300 x 689 Keyed Removable Mullion - 96" Aluminum Exit Device Support

The PDQ 9300 Series Keyed Removable Mullion is a heavy-duty architectural solution designed for double door openings that require both maximum security and temporary unobstructed access. At 96 inches (8 feet) in height, this mullion provides a rigid center strike post for PDQ 6300 and 6400 Series Rim Exit Devices. It is the premier choice for hospital corridors, school loading zones, and convention centers where the ability to move large machinery, gurneys, or palletized freight is a daily operational necessity.

Engineered for efficiency, the 9300 Keyed Mullion eliminates the labor-intensive process of manual unbolting. By simply using a standard rim cylinder key, the mullion can be detached from its top bracket in seconds. When the task is complete, the mullion is designed to self-lock back into the head bracket without the need for a key, ensuring the opening is immediately secured and the fire or panic exit hardware is once again fully functional.

Function Summary: Keyed Removal and Automated Security

The PDQ 9300 serves as a temporary structural member that allows two independent rim exit devices to function on a pair of doors.

• Quick-Release Access: Designed for high-demand environments, the keyed cylinder allows authorized personnel to remove the center post instantly. This transforms two smaller openings into one massive, clear-width passage for oversized equipment.
• Self-Locking Reinstallation: Safety is prioritized through a "slam-load" design. When the mullion is pushed back into the top bracket, it automatically clicks into a locked position. This ensures the center post is never accidentally left loose, which would otherwise compromise the latching of the panic bars.
• Rim Exit Device Integration: The mullion provides a fixed, stable surface for the 6300/6400 Series pullman latches to engage. This creates a much more secure and stable latching point than using a double-door strike on an inactive leaf.

Professional Solutions for Large-Scale Openings

The PDQ 9300 x 689 Mullion addresses the most common logistical and security challenges for wide entryways:

• Facilitates Large-Scale Transport: In healthcare and industrial settings, standard door widths are often insufficient. This mullion allows for the effortless passage of hospital gurneys, industrial carts, and large machinery, then restores the building's security envelope immediately afterward.
• Increased Security Over Double Door Strikes: Using a mullion is significantly more secure than latching two doors together. It provides a fixed vertical member that prevents the doors from being "pushed through" or manipulated at the meeting stiles.
• Maintenance Efficiency: Because the reinstallation is self-locking, maintenance staff do not need to fumble with keys or tools while holding a heavy center post. This reduces the risk of injury and ensures the hardware is re-engaged correctly every time.
• Retrofit Compatibility: The 96" height ensures that even oversized "High-Boy" door frames are covered. The aluminum construction is easily field-cut to match the specific height of your existing opening.
• Architectural Continuity: The 689 Aluminum finish provides a professional, clean look that matches standard clear-anodized storefronts and silver-painted door frames, maintaining the aesthetic integrity of the facility.
