Falcon 525 US28 – Frequently Asked Questions

1) What do Falcon 525 mullion stabilizers actually do on a pair of doors?
The Falcon 525 is a set of two aluminum stabilizers that brace the mullion on a double door opening running exit devices. They hold mullion alignment and cut flex and movement in the mullion assembly, which takes stress off the exit device mounting points and keeps the doors aligned as the assembly gets used. They are an installation accessory, not a latching part, so they add nothing to the security function on their own.
2) Do I need mullion stabilizers if my pair of doors has a removable mullion with exit devices?
They are for double door openings where the mullion carries exit device hardware and needs support against flex. If your pair has no mullion at all, for instance surface vertical rod devices latching at the head and sill, there is nothing for the 525 to stabilize and you do not need it. The 525 set is specifically for mullion stabilization on double door configurations.
3) Is the Von Duprin 040061 QEL conversion kit an alternative to the Falcon 525 mullion stabilizers?
No - the two do different jobs on a double door opening. The Falcon 525 is a set of 2 aluminum stabilizers that support the mullion and reduce flex and movement in the mullion assembly so exit device mounting points carry less stress. The Von Duprin 040061 is a QEL modular conversion kit that adds quiet electric latch retraction to 33A/35A/98/99 Series 3-foot and 4-foot exit devices; it changes how the device latch operates, not how the mullion is braced. If the mullion is moving under use, the 525 stabilizers are the part that addresses it, and a latch retraction kit will still leave that movement in place.
4) I need dogging on my 33A devices, not stabilization - what part covers that instead of the Falcon 525?
That is the Von Duprin 040070/040071, a 33 Series cylinder dogging with indicator conversion kit for 36-inch and 48-inch 33A exit devices, rated Grade 1. It converts the device to cylinder dogging with an indicator and is ordered by device length. The Falcon 525 aluminum stabilizers are a mullion support set of 2 for double door openings and have no effect on how the device dogs down. On a double door where both needs come up, they are separate line items: the dogging kit goes on the device, the stabilizers go to the mullion.
5) How many stabilizers come in a Falcon 525 order?
Two per set. The 525 ships as a pair so both sides of the mullion assembly get balanced support, which means one order covers one opening. If you are standardizing across a building, count one set per double door opening rather than one per leaf.
6) What finishes do the Falcon 525 mullion stabilizers come in?
Two anodized aluminum finishes: US28 aluminum anodized and SP313 dark bronze anodized. Those are the only two, so if the rest of the opening is in a plated or painted finish, pick whichever anodized option reads closest. On storefront and aluminum entrance work US28 usually matches the existing frame and SP313 matches dark bronze framing.
7) Is the Falcon 525 a repair part or something I add during a new exit device install?
Either. It is an installation accessory meant to be integrated with the exit device system, so it goes in on a new double door install, and it also solves an existing opening where the mullion flexes and the device mounting is working loose. Follow the parent device's installation instructions when fitting it, since the stabilizers work with the device already on the mullion rather than replacing any of its parts.
8) I need a Von Duprin exit device part, not a Falcon stabilizer. What else is out there for exit device conversion or repair?
The 525 is a Falcon mullion stabilizer and does nothing to the device itself. For device-side work, ZenSupply carries the Von Duprin 040061 QEL modular conversion kit for 33A/35A/98/99 Series 3-foot and 4-foot devices, the Von Duprin 040070/040071 33 Series cylinder dogging with indicator conversion kit for 36 inch and 48 inch 33A devices, and the Von Duprin 04116 and 041166 QELX kits for AX devices. Those change how the device works. The 525 only supports the mullion.
9) Will Falcon 525 stabilizers fix an exit device that is not latching at the top?
No. A device that misses its top latch is a latch or rod problem, not a mullion support problem. The 525 reduces mullion flex and keeps door alignment, which can help a device that binds because the mullion moves, but it replaces no latching component. For a failed top latch on an Accentra 7110 or 7120 device, the Accentra 7110/7120 top latch replacement component is the repair part, and there is a separate one for the 7110F.
10) What is the difference between the Falcon 525 mullion stabilizers and the Accentra 7110/7120 top latch replacement component?
They address opposite ends of the problem. The Accentra 7110/7120 top latch replacement component is a latching part for those exit devices - it is what gets ordered when the top latch itself is worn or damaged, and a matching version, the Accentra 7110F top latch replacement component, exists as well. The Falcon 525 is a pair of aluminum stabilizers that brace the mullion on double door applications so the exit device hardware stays in alignment and sees less stress. A door that will not latch at the top needs the latch component; a mullion that flexes and pulls the device out of alignment needs the stabilizers.
11) Do the Von Duprin QELX conversion kits for AX exit devices do the same thing as the Falcon 525 stabilizers?
No. The Von Duprin 04116 is a QELX modular conversion kit for AX exit devices with quiet electronic latch retraction, and the Von Duprin 041166 is the QELX baseplate conversion kit for the same AX devices - both are conversion kits that change the device itself over to electronic latch retraction. The Falcon 525 is a mechanical accessory: two aluminum stabilizers that hold the mullion steady on a double door and keep the exit device mounting points from taking the flex. Nothing in a QELX kit braces a mullion, and the 525 does not add any electrified function to a device.
12) My mullion hardware needs to match dark bronze - does the Falcon 525 come in anything other than aluminum finish?
Yes. The Falcon 525 aluminum mullion stabilizers are offered in US28 aluminum anodized and SP313 dark bronze anodized, so a dark bronze opening can be matched without a separate finishing step. Both are anodized aluminum, which is the same corrosion-resistant construction described for the set either way. Among the exit device accessories alongside it, parts like the Arrow 16RCR-27 SFIC rim housing for 24/25 Series devices are cylinder housings rather than mullion parts, so finish matching on a mullion comes down to the 525 options.
13) Will aluminum stabilizers hold up in a high traffic commercial entrance?
The 525 is built for commercial use, and the aluminum construction gives corrosion resistance for commercial environments while staying light. It is rated as a commercial part, and the intended jobs are office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities.
