Von Duprin VON-050364 – Frequently Asked Questions

1) Will the Von Duprin 050364 end case backplate fit any Von Duprin exit device, or only the 55 Series?
Only the 55 Series. The 050364 backplate is a genuine Von Duprin component made for the 55 Series exit device end case, and it is not an interchangeable part across Von Duprin's other device families. Check the device itself before ordering, not the door: the series stamp on the end case or the original order paperwork is what tells you whether a 55 Series part is the right one.
2) Can I use a Von Duprin 55 Series end case backplate on a fire rated door opening?
No. The 050364 end case backplate is not a fire rated component, so it should not be used to repair a device on a labeled fire door assembly. Fire door openings need hardware carrying a fire label, and swapping in a non-rated part can void the assembly's listing. For a non-rated opening (a standard exit or egress door in an office, school, or retail space) it is the correct repair part.
3) My 55 Series exit device end case is cracked. Do I replace the whole device or just the backplate?
If the damage is confined to the backplate itself, the 050364 is sold as a standalone replacement part and you keep the rest of the device, the rail, and the existing door prep. That is the point of it: worn, damaged, or missing backplates get swapped out without pulling and re-prepping the door. If the rail, latch, or chassis is also damaged, a part-level repair will not bring the device back and you are into a device replacement.
4) I have a mix of exit device brands in my building. Can an Accentra or Falcon replacement part substitute for the Von Duprin 55 Series backplate?
No. Exit device repair parts are brand and series specific, and none of them cross over. The Accentra 7110/7120 and 7110F top latch components are for Accentra devices, the Falcon 610061 top rod is for the F-25-C and F-25-CWDC concealed vertical rod devices in Falcon's 24 Series Monarch line, and the Falcon T Series 2-3/8 inch square corner deadlatch is a T Series part. For a Von Duprin 55 Series end case, order the Von Duprin part.
5) Will an Accentra 7110 top latch component work in place of a Von Duprin 55 Series end case backplate?
No. The Accentra 7110/7120 Exit Device Top Latch Replacement Component is a latching component for Accentra 7110 and 7120 devices, and the Accentra 7110F Exit Device Top Latch Replacement Component serves the 7110F. The Von Duprin 050364 is an end case backplate built for the Von Duprin 55 Series, so it is a different part in a different manufacturer's device. Exit device internals are not cross-brand interchangeable: order the backplate against the 55 Series device on the door, and order the Accentra latch components only when the device is an Accentra 7110, 7120, or 7110F.
6) My exit device is missing hardware at the top of the door, not at the end case. What part do I need instead of the 050364?
The 050364 backplate belongs to the end case assembly of a Von Duprin 55 Series device, so it does nothing for a problem at the top of the door. For a concealed vertical rod device, the Falcon 610061 24 Series Monarch Concealed Vertical Top Rod covers F-25-C and F-25-CWDC devices in the 245 Series. For a top latching component on an Accentra device, the Accentra 7110/7120 Exit Device Top Latch Replacement Component addresses the 7110 and 7120. Identify the device brand and series stamped on the chassis first, then match the part to it.
7) Is the Von Duprin 050364 backplate rated for high traffic commercial buildings?
It is built to Grade 1, which is the commercial-duty tier a locksmith or facility buyer specifies for high traffic openings, so it holds the same duty class as the original factory component in the device. Grade 1 exit hardware is what goes on school corridors, hospital egress doors, and multi-tenant stairwells. It is a commercial part, not a residential one.
8) Do I need anything else besides the 050364 backplate to finish a 55 Series end case repair?
The 050364 covers the backplate itself. If the repair is on a pair of doors and the problem is really that the leaves are racking or the devices are not staying aligned, the part to look at is the mullion, not the end case: the Falcon 4023 steel mullion serves double door exit device openings, and the Falcon 525 aluminum mullion stabilizers steady an existing mullion. Diagnose which of the two you have before ordering, since a backplate will not fix an alignment problem.
9) I am replacing the end case backplate on a pair of doors. Do I also need a mullion?
Those are separate decisions. The Von Duprin 050364 end case backplate restores a component of a single 55 Series device. A mullion is the removable vertical post that gives a pair of doors a strike surface: the Falcon 4023 Steel Mullion is made for double door exit device applications, and the Falcon 525 Aluminum Mullion Stabilizers are an exit device accessory that steadies a mullion. If the opening already has a mullion in place and only the device end case is damaged, the backplate is the part to order.
10) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 050364?
No, they solve different problems. The Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin configuration for the Arrow 24/25 Series, which is the cylinder side of the opening and is what you buy when keying or cylinder retrofit is the issue. The Von Duprin 050364 is a structural backplate in the end case of a 55 Series exit device and has no bearing on keying. A locksmith rekeying a building orders the rim housing; a technician repairing a damaged 55 Series end case orders the backplate.
11) Can I use a Falcon T Series deadlatch part to repair a Von Duprin 55 Series exit device?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, which is a cylindrical lock latch, not exit device hardware. The Von Duprin 050364 is an end case backplate for a Von Duprin 55 Series exit device. If the door has a T Series lockset with a worn latch, the Falcon deadlatch part is the correct order; if the door has a 55 Series push bar device with a damaged end case, the 050364 is.
12) How do I order the Von Duprin 55 Series end case backplate, and are there options to specify?
There is one part to order, model 050364, so there is no handing, finish, or length choice to make on it. Give the model number and the series and you have specified it completely. Handing does not enter into a 55 Series backplate order the way it does on a full device.
