Von Duprin 106222 US28 – Frequently Asked Questions
1) Will the Von Duprin 106222 ratchet release work on my 33A or 35A exit device?
The 106222 ratchet release package is built for Von Duprin 33 and 35 Series rim and mortise exit devices. It's the OEM ratchet release assembly for that family, so it goes back into the device you already have rather than forcing a full device swap. Because the 33/35 family covers several device configurations, match the part against the Von Duprin 33/35 Series parts list for your exact device before you order.
2) Can an Accentra 7110 top latch component be used to repair a Von Duprin 33 or 35 Series exit device?
No. The Accentra 60-7010-0049-999 is a top latch replacement component built for Accentra 7110/7120 exit devices, and the Von Duprin 106222 is a ratchet release package for Von Duprin 33 and 35 Series rim and mortise devices. They are different device families and different parts of the device - a top latch is the latching point at the head of the door, while the ratchet release is the mechanism inside the device chassis. For a 33 or 35 Series device, the 106222 is the genuine OEM ratchet release assembly; for an Accentra 7110 or 7120, the top latch component is the Accentra part. Neither crosses over.
3) What is the equivalent ratchet release part for a fire-rated exit device?
The Von Duprin 106222 ratchet release package carries no fire rating, so it is the part for standard 33 and 35 Series devices rather than fire-labeled openings. Among exit device replacement components, Accentra splits its top latch parts the same way: 60-7010-0050-999 is the top latch component for the fire-rated 7110F, while 60-7010-0049-999 covers the non-fire 7110/7120. If the opening is fire-labeled, confirm the part against the device manufacturer's fire-rated parts list before ordering, because the fire and non-fire versions of a given component are not interchangeable.
4) What finish should I order so the ratchet release matches the rest of my Von Duprin exit device?
Four finishes are offered on the 106222: 606 satin brass, 612 satin bronze, 628 aluminum, and 710 dark bronze. Pick the one already on the device, since the ratchet release is a visible piece of the assembly. 628 aluminum is the most common finish on installed 33/35 Series devices, and 710 dark bronze is the usual match for a bronze-toned storefront or entry set.
5) What actually comes in the Von Duprin 106222 ratchet release package?
It's a three-piece set: the ratchet body, a mounting plate, and the strike, all in the finish you order. That's the complete release assembly, so a maintenance tech can rebuild the ratchet release on a 33 or 35 Series device without ordering the pieces separately. It does not include the exit device itself or any outside trim.
6) Is it worth repairing a Von Duprin 33/35 exit device with a ratchet release package or should I replace the whole device?
Repair is the cheaper path when the device body and rail are sound and only the release mechanism is worn or sticking. The 106222 is a genuine OEM replacement that restores the ratchet release to factory specification and is rated Grade 1 for commercial use, so a device rebuilt with it holds the same duty rating it had originally. Replace the whole device instead when the rail is bent, the chassis is damaged, or you need a function the existing device does not have.
7) I need an exit device latch or release part but my device is not a Von Duprin. What are my options?
The 106222 is Von Duprin specific and won't cross over to another maker's device. For other brands, ZenSupply carries the Accentra 7110/7120 exit device top latch replacement component and the 7110F version for fire-rated 7110F devices, and the Falcon T Series 2-3/8 inch square corner deadlatch replacement part for T Series devices. Exit device internals are not interchangeable between manufacturers, so order the part that matches your device series.
8) I have a pair of doors with exit devices - is the 106222 the part that lets me keep both leaves usable?
No. The Von Duprin 106222 is a ratchet release package that repairs the release mechanism inside a single 33 or 35 Series device. What allows rim exit devices to be used on a double door opening is a mullion: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are an exit device accessory used with mullions. Those address the opening; the 106222 addresses a worn mechanism inside a device already mounted on the door.
9) The exit device latch is not holding - do I need the 106222 ratchet release or a deadlatch part?
Those are two different failures. The Von Duprin 106222 restores the ratchet release mechanism inside a 33 or 35 Series device to factory specification, which is what you replace when the release action itself is worn or binding. If the latchbolt is the problem - it is not deadlatching or the bolt face is damaged - that is a latch component, and each device family has its own: the Falcon 23981160 is the 2-3/8 inch square corner deadlatch replacement part for Falcon T Series. Diagnose which component has failed at the device before ordering, since a ratchet release will not correct a worn latch and a latch part will not correct a worn release.
10) Is the 106222 what I need for a concealed vertical rod exit device?
The Von Duprin 106222 ratchet release package is specified for Von Duprin 33 and 35 Series rim and mortise exit devices. Concealed vertical rod devices use rod assemblies as their latching hardware - for example, the Falcon 610061 is the 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices. If the device on the door is a concealed vertical rod unit rather than a rim or mortise device, the repair part comes from that device's rod and latch parts list, not from a rim and mortise ratchet release package.
11) Will replacing the ratchet release change the keying or cylinder on the exit device?
No. The Von Duprin 106222 is a ratchet release replacement package for 33 and 35 Series devices and does not include or alter any cylinder or keying component. Keying on a rim exit device is handled by the rim cylinder housing - for example, the Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin for Arrow 24/25 Series. If the goal is to rekey or convert to small format interchangeable core, that is a cylinder housing order; the 106222 is strictly a mechanism repair and leaves the existing cylinder in place.
12) Do I have to replace the whole exit device, or can I repair it with a component part?
A worn ratchet release on a Von Duprin 33 or 35 Series device can be corrected with the 106222 ratchet release package, which restores the mechanism to factory specification and returns the device to code-compliant operation without a full device replacement. Component-level repair is standard practice across exit device lines - Accentra sells top latch replacement components for its 7110/7120 devices, and Falcon sells deadlatch replacement parts for its T Series. For a facility standardizing on 33/35 Series, that means a worn device is usually a parts order against the 33/35 Series parts list rather than a new device and new door prep.
13) Is the Von Duprin 106222 ratchet release rated for high traffic commercial doors?
Grade 1, the heaviest commercial duty rating, and it's a commercial-use part rather than a residential one. That suits it to high-traffic exits in offices, schools, hospitals, and other institutional buildings, including scheduled preventive maintenance on 33/35 Series devices that see constant use.
14) Do I have to re-prep the door to install a Von Duprin 106222 ratchet release?
No new door prep. The 106222 is a replacement component that goes back into an existing 33 or 35 Series device on a door already prepped for it, which is the point of repairing rather than replacing. Door and frame preparation only comes into play if you swap the device itself for a different model.
