Von Duprin 050488 US26 – Frequently Asked Questions

1) Which Von Duprin exit devices does the 050488/050489 35A mechanism case fit?
The 050488/050489 35A mechanism case is built for Von Duprin 33 and 35 Series exit devices, as a direct replacement for the mechanism case on those assemblies. It is not a part for other Von Duprin series, so confirm the device on the door is a 33 or 35 before ordering.
2) Do I order the 36 inch or the 48 inch 35A mechanism case?
Match the case to the door width the device was furnished for. The 35A mechanism case comes in a 36 inch version and a 48 inch version, and the two are not interchangeable, so measure the leaf the existing device is mounted on before you pick one.
3) Can I use this mechanism case on a fire rated exit device?
No. The 050488/050489 35A mechanism case carries no fire rating, so it should not be used to service a labeled fire exit hardware opening. Fire rated Von Duprin devices need the fire rated component for that device to keep the label intact.
4) Can an Accentra 7110/7120 top latch part be used in place of the Von Duprin 35A mechanism case?
No. The Von Duprin 050488/050489 35A mechanism case is a replacement part for Von Duprin 33/35 Series exit devices, and it is the case that houses the device mechanism. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, so it is both a different manufacturer's device platform and a different component of the device. Neither part substitutes for the other; match the replacement part to the exit device brand and series already on the door.
5) My exit device is fire rated - is the Von Duprin 35A mechanism case the right part, or should I look at a fire-rated component?
The Von Duprin 050488/050489 35A mechanism case carries a fire rating of No, so it is intended for non-fire-rated openings. Among comparable exit device replacement components, the Accentra 60-7010-0050-999 is the top latch component for the 7110F fire-rated exit device, while the Accentra 60-7010-0049-999 serves the non-fire 7110/7120 devices. If the door is a labeled fire assembly, verify the part called out for the fire-rated version of the device you actually have before ordering.
6) What finishes does the Von Duprin 35A mechanism case come in?
Seven finishes, in both door widths: 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 625 bright chrome, 628 aluminum, and 710 dark bronze. For a repair, pick the code stamped on or specified for the existing device so the case matches the rest of the trim on the opening.
7) Is this part heavy duty enough for a school or hospital exit door?
It is a Grade 1 commercial component, the highest ANSI/BHMA commercial classification, and is intended for commercial rather than residential openings. That is the duty level specified for high traffic exits in schools, healthcare, and office buildings.
8) Is the 35A mechanism case the whole exit device or just one part of it?
Just one part. The mechanism case is the housing that holds the working mechanism of the push bar assembly, sold as a genuine replacement component for 33 and 35 Series devices. If the device itself is damaged beyond the case, or you are hardware a new opening, you need a complete exit device instead.
9) I need a latch component rather than a mechanism case for my exit device. What else is there?
Depends on the brand of device. For Accentra 7110/7120 devices there is the 7110/7120 top latch replacement component, and a separate version for the fire rated 7110F. Falcon T Series openings use the 2-3/8 inch square corner deadlatch replacement part, and Falcon 24 Series Monarch concealed vertical devices (F-25-C and F-25-CWDC) use the 610061 top rod. The Von Duprin 35A case only services Von Duprin 33 and 35 Series.
10) I have a pair of doors with rim exit devices and no mullion. Is this the part I need?
No. The 35A mechanism case services the push bar assembly on a 33 or 35 Series device, it does nothing for the gap between two leaves. For a pair of doors with rim devices you need a mullion, such as the Falcon 4023 steel mullion for double door exit device applications, and Falcon 525 aluminum mullion stabilizers where the mullion needs added support.
11) I need to secure a pair of doors, not repair one device - is a mechanism case what I want?
No. The Von Duprin 050488/050489 35A mechanism case is a replacement part for an existing 33/35 Series exit device on a single door. For a double-door opening, a mullion is the part that creates the strike point between the two leaves - the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are accessories used with exit device mullions. Those address the opening configuration; the 35A case addresses the device itself.
12) What is the difference between ordering the 35A mechanism case and ordering a vertical rod or latch part?
The Von Duprin 050488/050489 35A mechanism case is the housing that covers and carries the exit device mechanism along the door, which is why it is sized to the door width in 36 inch and 48 inch lengths. Latching hardware is a separate class of part: the Falcon 610061 is a concealed vertical top rod for F-25-C and F-25-CWDC exit devices, and the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for T Series devices. Replace the case when the housing is damaged; replace rods or latches when the device is not latching.
13) I want to rekey the exit device cylinder - does the 35A mechanism case cover that?
No. The Von Duprin 050488/050489 35A mechanism case is a commercial replacement part for the 33/35 Series exit device body. Cylinder work is handled by rim housings: the Arrow 16RCR-27 is an SFIC rim housing accepting 6 or 7-pin cores for the Arrow 24/25 Series. A locksmith standardizing a keyway would order the cylinder housing, not the mechanism case.
14) Will a 36 inch 35A mechanism case work if I cut it down for a narrower door?
Don't. The case is supplied sized for 36 inch and 48 inch door applications and is meant to drop into a device built for that width. Cutting one alters the mechanism housing and the push bar travel it supports. Order the size that matches the device as furnished.
