Von Duprin 50509 – Frequently Asked Questions

1) What does the Von Duprin 050509 strike hole plug actually do?
The 050509 is a small filler plug that covers the auxiliary fire latch strike hole on a Von Duprin exit device installation. When a device is changed out or a fire latch strike is removed, that prep leaves an open hole in the frame or device trim. The plug fills it so the assembly looks finished and the opening isn't left with an exposed cutout. It's a genuine Von Duprin replacement part, not a repair kit or a functional latch component.
2) Which Von Duprin exit devices does the 050509 plug fit?
It's made for the Von Duprin 33/35/98/99 Series family, with the 9927 and 9957-F configurations called out specifically. If you're working on a 98 or 99 Series device, this is the matching plug. For a device outside that family, it is not the right part.
3) Is the 050509 plug itself fire rated?
No. Even though it plugs an auxiliary fire latch strike hole, the plug carries no fire rating of its own. It's a cosmetic and cover part. If your opening is a fire door, the fire rating comes from the exit device and the labeled assembly, not from this piece, so don't treat the plug as a substitute for a required fire latch component.
4) Is there an equivalent plug from another brand that will fill the auxiliary fire latch strike hole on a Von Duprin 9957-F?
No. The Von Duprin 050509 auxiliary fire latch strike hole plug is a genuine OEM part matched to the 33/35/98/99 Series device chassis, and the hole it covers is specific to that Von Duprin trim. The other exit device replacement parts sold alongside it belong to different manufacturers' platforms - the Accentra 7110/7120 top latch component and the Accentra 7110F top latch component fit Accentra devices, and the Falcon 610061 top rod fits Falcon F-25-C and F-25-CWDC 24 Series Monarch devices. None of those are dimensioned to the Von Duprin opening, so for a 9927 or 9957-F you order the 050509 itself.
5) Do I need to take the exit device off the door to install the 050509 plug?
It's a drop-in component, meant to go into the existing auxiliary fire latch strike hole without swapping out the device. That's the point of stocking it: a maintenance tech can restore the appearance of the assembly rather than replacing a whole exit device or trim piece.
6) We are ordering parts for a pair of doors with no center post - is the 050509 what holds the second leaf?
No. The 050509 is a replacement plug for the auxiliary fire latch strike hole on 33/35/98/99 Series devices and has no role in a double door opening. For a double door without a center post, the parts that address that are mullions: the Falcon 4023 steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers. Those are separate line items from any strike hole plug.
7) Does buying the 050509 plug affect the fire rating of the opening, and is there a fire-rated alternative part?
The Von Duprin 050509 carries a fire rating of No as a component and is a Grade 1 commercial replacement part; the rating of the opening comes from the exit device and door assembly, not from the plug. Comparable exit device components are in the same position - the Accentra 7110/7120 top latch component and the Accentra 7110F top latch component both list a fire rating of No. If the opening is fire-rated, the specification to confirm is the labeled device, such as a 9957-F, and its listed components.
8) A supplier offered me a Falcon deadlatch part as a substitute for the Von Duprin 050509 - will that work?
It will not. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, which is a latching component in a different manufacturer's product line. The Von Duprin 050509 is a non-latching plug for the auxiliary fire latch strike hole on 33/35/98/99 Series devices such as the 9927 and 9957-F. Different function, different platform - the two are not interchangeable.
9) Is this a commercial-duty part or something lighter?
Commercial. The 050509 is rated Grade 1 and is catalogued as commercial hardware, which is the same duty tier as the 98/99 Series devices it goes on. It shows up in offices, schools, hospitals, retail, warehouses, multi-tenant housing and government buildings, which is exactly where those Von Duprin devices are installed.
10) Is there more than one version of the 050509 to choose from?
No options to sort through. The plug is sold as a single model, 050509, with no finish or size variations to specify. Order it by that number and you have the part.
11) What do I order if I need to add or change cylinder housing on a rim exit device rather than plug a hole?
That is a different part entirely. The Von Duprin 050509 only fills the auxiliary fire latch strike hole on 33/35/98/99 Series devices and has nothing to do with keying. For small format interchangeable core work on a rim device, the Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the Arrow 24/25 Series. Confirm the housing suits the device brand on the door before ordering.
