PDQ 9301F Hex-Key Removable Mullion, Fire Rated

9300 Series Removable Mullion for Double Doors

The PDQ 9300 Series is a removable mullion for pairs of doors fitted with PDQ 6300R and 6400R rim exit devices. Each door latches into the mullion, and the mullion can be removed from the top bracket with a rim cylinder key (9300) or a hex key (9301) to turn the pair into one wide, unobstructed opening for moving equipment, furniture or deliveries. When it goes back in, the mullion self-locks with no key required.

A powder coated 2" x 3" steel tube with a 3/16" wall is held by cast stainless steel head and foot brackets. Fire rated models (9300F and 9301F) are UL 10C listed for 3 hours on pairs up to and including 8' x 8' when used with PDQ 6300RF and 6400RF rim devices.

Frequently Asked Questions

What is a mullion, and why use one instead of vertical rod exit devices?
A mullion is a post installed between a pair of doors so each leaf can carry its own independent rim exit device rather than needing surface or concealed vertical rods. The PDQ 9300 works with 6300R and 6400R rim devices, letting each door latch into the mullion.

Is the 9300 mullion fire rated?
The fire rated models are 3-hour fire labeled for door pairs up to 8' x 8' when used with fire rated 6300RF and 6400RF rim devices, and include the 639080 strike required for fire labeled installations.

When should a mullion be used instead of the 6300V or 6300C?
Choose the 9300 mullion with two rim devices when a visible center post is acceptable and a simpler latching setup is preferred. Choose surface (6300V / 6400V) or concealed (6300C / 6400C) vertical rod devices when the opening must stay mullion-free.

PDQ 9301F600 – Frequently Asked Questions

1) Will the PDQ 9301F removable mullion work with any brand of rim exit device?
No. The 9301F is built to pair with PDQ 6300R and 6400R rim exit devices, and the fire rated listing applies only when it is used with PDQ 6300RF and 6400RF fire rated rim devices. Each leaf latches into the mullion, so if the doors carry another manufacturer's rim device, this is not a listed combination.
2) What is the fire rating on the PDQ 9301F mullion, and what size pair does it cover?
Three hours, UL 10C listed, on pairs of doors up to and including 8 feet by 8 feet when used with PDQ 6300RF or 6400RF rim devices. The fire rated mullion maxes out at 8 feet, so a 10 foot opening cannot be done with a labeled mullion.
3) Do I need a key to put the mullion back in after I take it out?
No key for reinstall. The 9301F drops back into the head bracket and self-locks on its own. Removal is what needs a tool: on the 9301 you back it out of the top bracket with a hex key, while the 9300 version uses a rim cylinder key instead.
4) Is a strike included with the PDQ 9301F fire rated mullion?
Yes. Fire labeled mullions ship with the 639080 strike, two ML strikes included, which is what a fire labeled installation requires. Non-fire panic mullions do not include a strike, you use the one supplied with the exit device.
5) Can the PDQ 9301F mullion be cut down to fit a shorter opening?
Yes, the mullion is field cuttable to a shorter size. It is offered in 8 foot and 10 foot lengths, but the fire rated version is capped at 8 feet, so a fire labeled job starts from the 8 foot and under tube.
6) What finishes does the PDQ 9301F come in, and can I paint it to match my frames?
Two choices: 689 aluminum powder coat, which can be painted over, or 600 primed for painting if you intend to finish it on site to match the frames. Order part 9301F689 for the aluminum or 9301F600 for the primed version.
7) Can I run wiring through a PDQ 9300 Series mullion for electrified exit devices?
Yes, with the EM option. PDQ preps the mullion at the factory with wire routing and industry standard Molex plug connectors, so electrified rim devices on the pair can be wired without field drilling the tube. It has to be specified when the mullion is ordered.
8) What is the difference between the PDQ 9300 and the 9301 mullion?
Only how you remove it. The 9301 is backed out of the top bracket with a hex key; the 9300 uses a rim cylinder key, which means buying a cylinder for it. Both self-lock when reinstalled, and both have fire rated versions (9300F and 9301F). If you do not want another keyed cylinder in the building, the hex key 9301F is the simpler order.
9) How tough is the mullion tube itself, for a loading dock or high traffic double door?
The post is a powder coated steel tube, 2 inches by 3 inches with a 3/16 inch wall, carried by cast stainless steel head and foot brackets. That is a commercial duty assembly meant to be pulled and replaced repeatedly in service corridors and delivery openings.
10) Does the PDQ 9301F mullion qualify for a federal job with domestic sourcing requirements?
It meets BAA requirements as a commercial off the shelf product manufactured in the United States, which is what government and institutional specs typically ask for on hardware of this type.
