Von Duprin 050278 26D – Frequently Asked Questions

1) Is there an equivalent release guide cover from another exit device brand that will fit a Von Duprin 55/88 device?
No. The Von Duprin 050278 8847-F release guide cover is an OEM replacement part built for the 55/88 Series, and exit device internal parts are not cross-brand interchangeable. The other exit device service parts available are brand- and series-specific in the same way: the Accentra 7110/7120 exit device top latch replacement component fits Accentra 7110/7120 devices, and the Falcon 610061 top rod is for Falcon 24 Series Monarch F-25-C and F-25-CWDC concealed vertical rod devices. If the device on the door is a Von Duprin 55 or 88, the 050278 is the part to order.
2) Do I need to buy mounting screws separately for the 8847-F release guide cover?
No. The 050278 ships with its mounting screws, so a maintenance tech can go straight to the door without sourcing fasteners. Nothing else is supplied with it, it is the cover and screws only.
3) Can I use the Von Duprin 050278 cover on a fire rated exit device opening?
The 050278 release guide cover carries no fire rating of its own. On a labeled opening, the rating is carried by the exit device and door assembly, so replacing a non-rated trim cover does not give you a rated part. If your specification calls for a listed component, verify against the device label rather than this cover.
4) Is this a commercial duty part or a light duty replacement?
Grade 1, commercial. That is the heaviest ANSI/BHMA duty class, which is what you want on high traffic openings in schools, hospitals, offices and government buildings where the device gets cycled all day.
5) What finish does the 8847-F release guide cover come in?
Satin chrome, 626. That is the standard commercial finish on most Von Duprin 55 and 88 Series devices, so a cover swap on an existing 626 device will match the rest of the hardware. If your devices were ordered in a brass or dark bronze finish, this cover will not match them.
6) I need a fire-rated exit device part - does the 8847-F release guide cover qualify?
The Von Duprin 050278 8847-F release guide cover carries a Fire Rating of No, as do the Accentra 7110/7120 and 7110F top latch replacement components. If your opening requires fire-labeled hardware, specify a part that carries the label rather than substituting a non-rated service component.
7) What do I order if I am trying to apply exit devices to a pair of doors rather than service one device?
The Von Duprin 050278 is a Grade 1 commercial replacement part for an existing 55/88 Series device, so it does nothing for a double-door application. For pairs, 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 mullion installations.
8) I need to rekey or change the cylinder on a rim exit device - is this the right part?
No. The Von Duprin 050278 8847-F release guide cover is a mechanical cover for the release guide on 55/88 Series devices and has nothing to do with keying. Cylinder work on a rim device uses a rim housing such as the Arrow 16RCR-27 SFIC rim housing for 6- or 7-pin small format interchangeable cores, part of the Arrow 24/25 Series.
9) Is the 050278 a genuine Von Duprin part or an aftermarket copy?
It is a genuine OEM Von Duprin component, supplied as the factory 8847-F cover. For facilities standardizing on Von Duprin across a building, that keeps the device to original manufacturer specification rather than mixing in aftermarket trim.
10) Does a Falcon T Series deadlatch part work as a substitute for the Von Duprin release guide cover?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, a latch component for a different brand and series entirely. The Von Duprin 050278 8847-F release guide cover is an OEM cover for Von Duprin 55/88 Series exit devices and ships with its mounting screws.
