Von Duprin 90040 – Frequently Asked Questions

1) What does the Von Duprin 090040 dogging shaft actually do on a 22 Series exit device?
The 090040 is the shaft inside the dogging mechanism on a Von Duprin 22 Series exit device. Dogging is what lets you hold the push pad depressed and the latchbolt retracted so the door pushes free during business hours. When the dogging stops holding, or the hex key turns without catching, the shaft is the part that gets replaced. It restores the dogging function; it is not the latch, the push rail, or the case.
2) My exit device dogging will not hold the push bar down. Do I need a new device or just a part?
On a Von Duprin 22 Series, dogging that will not hold is usually a worn or sheared dogging shaft, not a failed device. The 090040 replaces that shaft and brings the hold back. Replacing the shaft is a far smaller job than pulling the device and re-prepping the door, and the rest of the 22 Series chassis stays as installed.
3) Can I use the Von Duprin 090040 dogging shaft on a fire rated opening?
No. The 090040 is a non fire rated component, and dogging is not permitted on fire exit hardware because the latch must be free to project and latch the door. Among the exit device service parts alongside it, the Accentra 7110F top latch component 60-7010-0050-999 is likewise non fire rated. On a fire rated opening, the exit device is specified without mechanical dogging in the first place, so there is no dogging shaft to service.
4) Is the Falcon 610061 top rod a substitute for a Von Duprin 22 Series dogging shaft?
No. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, so it is the vertical rod that drives a top latch on a Falcon concealed vertical rod device. The Von Duprin 090040 is the dogging shaft for Von Duprin 22 Series devices, the component that lets the push rail be held down with the latchbolt retracted. They sit in different devices and perform different jobs, so one cannot stand in for the other.
5) My exit device will not hold the latch retracted - do I need a dogging shaft or a top latch part?
It depends on the device and the symptom. If the push rail depresses but will not stay dogged down on a Von Duprin 22 Series device, the dogging shaft is the component that holds it, and the 090040 is that part, supplied two to a package. If the failure is at the top of the door on an Accentra 7110/7120 or 7110F device, the corresponding part is a top latch replacement component - the 60-7010-0049-999 covers 7110/7120 and the 60-7010-0050-999 covers 7110F. Latching hardware and dogging hardware are separate assemblies, so identify which one is failing before ordering.
6) How many dogging shafts come in the Von Duprin 090040?
Two per package. That matters if you are servicing a pair of doors or a run of openings on a maintenance sweep, since one order covers two devices, or one repair plus a spare on the truck.
7) Is the Von Duprin 090040 a genuine OEM part or an aftermarket copy?
Genuine Von Duprin. It is the factory replacement shaft for the 22 Series, so the fit into the existing dogging bore is the same as the part that came out. On a Grade 1 commercial device, an off-brand shaft is the usual cause of a repeat failure.
8) I need an exit device repair part but my device is not a Von Duprin 22. What are the equivalents?
Exit device internals do not cross brands, so match the part to your device. For Accentra 7110/7120 devices there is a top latch replacement component, with a separate version for the fire rated 7110F. Falcon has a T Series 2-3/8 inch square corner deadlatch replacement, and a 610061 concealed vertical top rod for the 24 Series Monarch F-25-C and F-25-CWDC. The 090040 shaft will not serve any of those.
9) I need to hold a pair of doors open for deliveries - is a dogging shaft the right part, or a mullion?
Those solve different problems. The Von Duprin 090040 dogging shaft restores the dogging mechanism that holds an exit device latchbolt retracted for push-through traffic on a 22 Series device, which is what you want on a single leaf that needs to stay free-swinging. A mullion is the removable center post that lets a pair of doors carry rim devices, and Falcon covers that with the 4023 steel mullion for double door exit device applications, plus the Falcon 525 aluminum mullion stabilizers. If the doors are already hung and only the latch retraction is failing, the dogging shaft is the part.
10) Will an Arrow 16RCR-27 rim housing work with a Von Duprin 22 Series exit device?
The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing built for the Arrow 24/25 Series, so it is a cylinder housing for keyed outside access, not a Von Duprin 22 Series service part. The Von Duprin 090040 is the 22 Series dogging shaft, a Grade 1 commercial replacement component for the dogging mechanism inside the device. A keyed cylinder and a dogging shaft address different functions, and the Arrow housing is dimensioned to its own series.
11) What is the difference between a dogging shaft and a deadlatch replacement part like the Falcon 23981160?
The Falcon 23981160 is a T Series 2-3/8 inch square corner deadlatch replacement part, meaning it is the latch body that engages the strike and is sized to a specific backset and corner prep. The Von Duprin 090040 is the dogging shaft for 22 Series exit devices and controls whether the latch is held retracted rather than doing the latching itself. Ordering a deadlatch when the dogging mechanism is worn leaves the original fault in place.
12) Where do I find the door prep and template information for a Von Duprin 22 Series device?
Von Duprin publishes separate template indexes for the 22 Series covering hollow metal door prep, wood door prep, and the trim and strike preps for each. Those are the drawings to pull if you are also replacing trim or a strike while the device is off the door. Swapping the dogging shaft itself does not change the door prep, so nothing needs re-templating for that repair alone.
13) Is a Von Duprin 22 Series exit device Grade 1?
Grade 1 is the rating carried on the 22 Series hardware and on this replacement shaft, which is the commercial duty level specified for high traffic openings like schools, hospitals, and office towers. Repairing with the OEM Grade 1 shaft keeps the serviced device at the duty level the opening was specified to.
14) I have double doors with an exit device on each leaf. Does one package of dogging shafts cover both?
Yes, if both leaves carry non-fire 22 Series devices. The package holds two shafts, one per device. If the pair is held by a removable mullion instead, note that the mullion itself is a separate item, such as the Falcon 4023 steel mullion for double door exit device applications, and it has nothing to do with the dogging repair.
