Von Duprin 50404 – Frequently Asked Questions

1) What exactly does the Von Duprin 050404 center case kit include, and do I get the cover with it?
The 050404 is the center case assembly for Von Duprin 33 and 35 Series exit devices, supplied less cover. The pushpad end cap or center case cover is not part of the kit, so if yours is damaged or missing you'll need to source that separately. Images and part reference tie it to the 33/3527A center case configuration.
2) Will the 050404 center case fit my Von Duprin 22 Series or 98/99 Series exit device?
No. This center case kit is built for the 33 and 35 Series only. The 22, 98/99 and other Von Duprin families use different center case assemblies and the part won't interchange. Match the series stamped on your device before ordering.
3) Can I use this on a fire rated exit device opening?
Not as a fire rated component. The 050404 center case kit is listed with a fire rating of No, so it should go on non-fire-rated 33/35 Series devices. On a labeled fire door assembly, every part of the exit device has to keep the label intact, which means using the fire-rated equivalent component for that device.
4) Can I use an Accentra 7110 exit device latch part to repair a Von Duprin 33 or 35 Series device?
No. The Von Duprin 050404 is a center case kit (less cover) built for the Von Duprin 33 and 35 Series exit devices, and it is the assembly that sits behind the push rail at the middle of the device. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, and 60-7010-0050-999 is the top latch component for the fire-rated 7110F. Those are a different manufacturer's device line and a different position on the door, so they are not interchangeable with a 33/35 Series center case.
5) Is repairing the center case worth it versus replacing the whole exit device?
If the rails, rods and latches are still sound and the failure is in the center case mechanism, the 050404 restores the device without pulling the whole assembly or re-prepping the door. That keeps the existing door prep, trim and cylinder in place. If the device is worn through at multiple points, or the opening is fire rated, a full device swap is the better call since this kit is a non-fire-rated repair part.
6) Is this a genuine Von Duprin part or an aftermarket copy?
It's a Von Duprin OEM component for the 33/35 Series, built to Grade 1 commercial standards. That matters on a device where the touchpad geometry and latch linkage have to line up exactly with what's already on the door.
7) My exit device isn't Von Duprin. What replacement latch or rod parts are there for other brands?
Von Duprin center cases don't cross over, so go by the brand on your device. ZenSupply carries the Accentra 7110/7120 exit device top latch replacement component and the 7110F version, the Falcon T Series 2-3/8 inch square corner deadlatch, and the Falcon 610061 concealed vertical top rod for 24 Series Monarch F-25-C and F-25-CWDC devices. For an SFIC rim housing on Arrow 24/25 Series, there's the Arrow 16RCR-27 in 6/7-pin.
8) My exit device problem is at the top of the door, not the center rail - is the Von Duprin 050404 still the right part?
Probably not. The 050404 covers the center case assembly of a Von Duprin 33 or 35 Series device, which is the mechanism under the push pad itself. If the failure is at a top latch or top rod, that is a different component: for example, Falcon 610061 is the 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices, and Accentra 60-7010-0049-999 is a top latch component for 7110/7120 devices. Those are brand- and series-specific, so match the part to the device already on the door.
9) Is there an alternative to the Von Duprin 050404 if the device on the door is a Falcon T Series?
Yes, but it is not a center case swap. The 050404 is specific to Von Duprin 33 and 35 Series devices. For a Falcon T Series rim device, the matching internal service part in the same family is the Falcon 23981160, a 2-3/8 inch square corner deadlatch replacement part for the T Series. Choose the part by the series stamped on the device rather than by the symptom.
10) Will the Von Duprin 050404 work on a fire-rated opening?
The Von Duprin 050404 center case kit is a Grade 1 commercial component that is not fire rated. Among comparable exit device service parts, the Accentra 60-7010-0049-999 top latch component is likewise not fire rated, while 60-7010-0050-999 is the component for the 7110F device. For a labeled opening, confirm the complete device assembly carries the required listing before ordering any service part.
11) I manage a portfolio of buildings with Von Duprin 33/35 devices. Is this a part worth stocking?
Yes, for anyone maintaining a fleet of 33/35 Series devices it's a sensible shelf item. The center case is the part that carries the pushpad linkage and takes the abuse in high-traffic openings, and a stocked kit means a repair instead of a door left insecure. It suits commercial use, offices, schools, healthcare, retail and multi-tenant residential included.
12) I'm fixing a pair of doors with exit devices. Do I need anything besides the center case kit?
The 050404 only addresses the center case on a 33/35 Series device. If the problem on a pair is that the doors need a vertical member between them, that's a mullion, not a center case. ZenSupply carries the Falcon 4023 steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers.
13) What is the difference between the Von Duprin 050404 and exit device accessories like mullions or SFIC rim housings?
The 050404 is an internal working assembly - the center case kit, less cover, for Von Duprin 33 and 35 Series devices. Accessories serve the opening rather than the device mechanism: Falcon 4023 is a steel mullion for double door exit device applications, Falcon 525 are aluminum mullion stabilizers for exit devices, and Arrow 16RCR-27 is a 6/7-pin SFIC rim housing that carries the cylinder for keyed access. None of those restore center case function; they solve separate parts of the installation.
