Von Duprin 050486 US26 – Frequently Asked Questions

1) Which Von Duprin exit devices does the 33A mechanism case fit?
The 33A mechanism case is a replacement part for Von Duprin 33 and 35 Series exit devices. It is the housing the push pad mechanism sits in, so it goes back on the same device family it came off. It will not serve as a mechanism case for other Von Duprin series.
2) Can I use the 33A mechanism case on a fire rated exit device?
No. The 33A mechanism case carries no fire rating. If the opening is a labeled fire door, the whole exit device assembly has to be listed fire exit hardware, and a non-rated service part is not the right route back to a compliant opening.
3) My push bar works but the case is dented. Do I replace the whole exit device?
Not necessarily. Von Duprin sells the 33A mechanism case as a standalone service part for 33 and 35 Series devices, so a damaged or corroded case can be swapped while the rest of the device stays on the door. That keeps the existing keying, trim, and strike prep untouched, which is why property managers standardizing a building usually repair rather than replace.
4) Is the Accentra 7110/7120 top latch component an alternative to the Von Duprin 33A mechanism case?
No. The Von Duprin 050486/050487 33A mechanism case is a replacement part for Von Duprin 33 and 35 Series exit devices, covering 36 inch and 48 inch door applications. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices. They are different parts of the device on different manufacturers' hardware, so one cannot stand in for the other. Both are non fire rated parts, so neither belongs on a labeled fire door assembly.
5) I need a service part for a fire labeled exit device - can I use the Von Duprin 33A mechanism case?
The Von Duprin 050486/050487 33A mechanism case is not fire rated, so it should not be used on a fire labeled opening. Among the other exit device service parts, the Accentra 60-7010-0050-999 top latch component is the one built for the 7110F fire rated exit device. Match the service part to the label on the device you are repairing rather than substituting across families.
6) What finishes does the Von Duprin 33A mechanism case come in so I can match the rest of my device?
Eight finishes are offered on both the 36 inch and 48 inch cases: 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 625 bright chrome, 628 aluminum, 710 dark bronze, and 711 flat black. For a partial repair, match the code stamped on the existing device rather than eyeballing the color, since 612 and 710 read very close on an aged door.
7) Is the 33A mechanism case rated for high traffic commercial openings?
It is a Grade 1 commercial component, which is the heaviest duty ANSI/BHMA classification and what school, healthcare, and government corridor openings are normally specified to. It is built for commercial service, not residential use.
8) What is the difference between the Von Duprin 33A mechanism case and the Falcon 610061 vertical rod?
They serve different roles in an exit device. The Von Duprin 050486/050487 33A mechanism case is the housing that carries the operating mechanism on 33 and 35 Series devices in 36 inch and 48 inch door widths. The Falcon 610061 is a concealed vertical top rod for 24 Series Monarch F-25-C and F-25-CWDC devices, which is the linkage that drives the top latch. If the rail body is damaged you need the mechanism case; if the door is not latching at the top of a Falcon concealed vertical rod device, the rod is the part in question.
9) My double door pair keeps failing at the center - do I need a mechanism case or something else?
A mechanism case will not address a center latching problem on a pair. The Von Duprin 050486/050487 33A mechanism case is a Grade 1 replacement housing for 33 and 35 Series rim device rails. For a double door opening that needs a strike surface in the middle, the Falcon 4023 steel mullion is the part that serves double door exit device applications, and the Falcon 525 aluminum mullion stabilizers address movement at the mullion. Those are opening level components, not internal device parts.
10) Can the Arrow 16RCR-27 rim cylinder housing be ordered instead of the 33A mechanism case when rekeying?
No, they solve different problems. The Arrow 16RCR-27 is a small format interchangeable core rim housing taking a 6 or 7 pin core, used on Arrow 24/25 Series devices for the keyed side of the opening. The Von Duprin 050486/050487 33A mechanism case is the structural housing for the push rail mechanism on Von Duprin 33 and 35 Series devices in 36 inch and 48 inch widths. A rekey calls for cylinder hardware; a worn or damaged rail body calls for the mechanism case.
11) I have a pair of doors with no mullion. Does the 33A mechanism case solve that?
No, a mechanism case is an internal service part and does nothing about the opening configuration. A pair of doors running rim devices needs a mullion between them, such as the Falcon 4023 steel mullion for double door exit device applications, with Falcon 525 aluminum mullion stabilizers if the mullion needs bracing.
12) Does the Falcon T Series deadlatch part work as a substitute for a Von Duprin exit device mechanism case?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for Falcon T Series locks, which is a latch component for a lockset prep. The Von Duprin 050486/050487 33A mechanism case is a commercial exit device part for Von Duprin 33 and 35 Series rails. Different device families and different door preps, so there is no interchange between them.
