Von Duprin 050405 – Frequently Asked Questions

1) Will the 050405 center case fit an Accentra or Falcon exit device?
No. The 050405 is machined for the Von Duprin 33/3547A center case and will not drop into another manufacturer's device. Exit device internals are brand and series specific. If you are rebuilding an Accentra 7110 or 7120, the top latch replacement component for those devices is the matching part, and Falcon T Series deadlatch and 24 Series concealed vertical rod parts are the equivalents on that side. Identify the brand and series stamped on your device before ordering any internal component.
2) Does the Von Duprin 050405 center case kit come with a cover?
No cover is included. The 050405 is supplied less cover, so you reuse the cover off the existing 33 or 35 Series device or source one separately. If your old cover is bent, scratched, or the wrong finish for the job, plan on that as a second line item, because nothing in this kit will hide the case.
3) Can a Falcon 610061 top rod be used to repair a Von Duprin 33 or 35 Series device instead of the 050405 center case kit?
No. The Von Duprin 050405 is a center case kit for 33/35 Series exit devices, supplied less cover, and it replaces the assembly at the middle of the device where the push rail acts. The Falcon 610061 is a concealed vertical top rod for the 24 Series Monarch F-25-C and F-25-CWDC devices, so it is a different brand's rod for a different device family and does not address a worn or damaged center case. If the fault is in the center case of a 33 or 35 Series device, the 050405 is the part that corresponds to it.
4) Is it worth rebuilding a 33 or 35 Series exit device with a center case kit instead of replacing the whole device?
If the rails, end case, and door prep are sound and only the center case mechanism has failed, the 050405 puts the device back in service without re-prepping the door or re-matching finishes across the other openings. That is the usual call in a school or office building where a dozen doors carry matching 33 or 35 Series devices and you want them to stay matching. Replace the whole device instead when the rail is bent, the prep is wrong, or the opening now needs a fire rated assembly, since this kit is not rated.
5) Is the Von Duprin 050405 a Grade 1 commercial part?
Grade 1, and specified for commercial use. That is the duty level a facility wants on high traffic egress doors in schools, hospitals, retail, and municipal buildings, and it is the reason to put a genuine Von Duprin center case back into a 33 or 35 Series device rather than a generic rebuild.
6) How do I tell whether I need a center case kit or a latch or rod part for my exit device?
Watch what the device does when you push the pad. If the pad travels but nothing retracts, or the pad feels dead or gritty, the failure is in the center case mechanism, which is what the 050405 replaces on 33 and 35 Series devices. If the pad works and the door still will not release, the problem is downstream at the latch or the rod: a top latch component on a vertical rod device, or a deadlatch on a rim device. Those are separate parts, not something a center case kit fixes.
7) Do I need to know the device model before ordering the Von Duprin 050405?
Yes, check the device first. The 050405 is built for the 33/3547A center case configuration within the 33 and 35 Series family. Von Duprin exit devices in that family come in rim, surface vertical rod, and mortise variants, and internal parts are not interchangeable across every one of them, so read the model off the device or the end case before ordering.
8) What is the difference between a center case kit and an exit device top latch replacement component?
A center case kit such as the Von Duprin 050405 replaces the central mechanism housing of a 33 or 35 Series exit device and is supplied less cover, so an existing cover carries over. A top latch component such as the Accentra 60-7010-0049-999 for 7110/7120 devices, or the 60-7010-0050-999 for the 7110F, replaces the latching hardware at the head of the door rather than the mechanism behind the push rail. The two address different failure points, and each is built for its own manufacturer's device family.
9) The exit device on a pair of doors keeps binding at the astragal. Is a center case kit the right part?
Not if the problem is at the meeting point of a double door rather than in the device itself. The Von Duprin 050405 center case kit repairs the mechanism of a single 33 or 35 Series device. For double door openings, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 is an aluminum mullion stabilizer for exit devices. Those address how the pair of doors is closed off at the center of the opening; the 050405 addresses the device on the door leaf.
10) Does a Falcon T Series deadlatch part do the same job as the Von Duprin 050405?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, which is the latch that engages the strike in the door edge. The Von Duprin 050405 is the center case kit for 33 and 35 Series exit devices, rated Grade 1 for commercial use, and it sits behind the push rail rather than at the door edge. A device with a worn latch and a device with a worn center case need different parts.
11) Is the Von Duprin 050405 center case kit suitable for a fire rated opening?
The Von Duprin 050405 center case kit carries a fire rating of no, as do the Accentra 60-7010-0049-999 and 60-7010-0050-999 exit device top latch components. On a labeled opening, confirm the device assembly as a whole against the door and frame labels before selecting any replacement component.
12) We need to rekey the cylinder in an exit device, not repair the mechanism. What part covers that?
Cylinder work is separate from the Von Duprin 050405, which is a replacement center case kit for 33 and 35 Series devices and carries no cylinder. For small format interchangeable core work, the Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin, from the Arrow 24/25 Series. Order the center case kit when the device mechanism is the fault and the rim housing when the keying hardware is what is changing.
