Von Duprin 50494 – Frequently Asked Questions

1) My exit device has electric latch retraction. Is the Von Duprin 050494 the correct top latch?
No. The 050494 is the Non-EL version, meaning it suits standard mechanical devices with no electrified latch retraction. If your device is an EL (electric latch retraction) unit, you need the EL top latch assembly instead. Putting a Non-EL latch on an EL device will not give you the retraction function.
2) Can I use this Von Duprin top latch kit on a fire rated door?
Not as a fire rated component. The 050494 top latch kit carries no fire rating, so it belongs on non-fire-rated openings. Fire rated exit device assemblies have to be repaired with the fire-labeled parts for that device, since swapping in an unrated component can void the door assembly's label under the inspection rules for fire door assemblies.
3) I have Accentra exit devices, not Von Duprin. Can I use the 050494?
No. Exit device latch assemblies are brand and series specific, and the 050494 is made for Von Duprin 33/35/98/99 Series devices only. For Accentra hardware, ZenSupply carries the Accentra 7110/7120 exit device top latch replacement component, and a separate top latch component for the 7110F. Match the part to the device series stamped on your rail.
4) Is there a top latch replacement for an Accentra 7110 exit device, or does the Von Duprin 050494 work on it?
The Von Duprin 050494 top latch kit is built for Von Duprin 33/35/98/99 Series exit devices and should be kept on those devices. For an Accentra 7110 or 7120 device, the correct part is the Accentra 60-7010-0049-999 top latch replacement component. If the device is the fire-rated 7110F, use the Accentra 60-7010-0050-999 top latch replacement component instead - the F device takes its own top latch part number.
5) My Falcon concealed vertical rod device won't latch at the top - is the Von Duprin 050494 the part I need?
No. The 050494 top latch kit is a Von Duprin part for 33/35/98/99 Series devices. On a Falcon 24 Series Monarch concealed vertical rod device, the top-end part is the Falcon 610061 concealed vertical top rod, which serves F-25-C and F-25-CWDC exit devices. A top rod and a top latch kit are different assemblies, so confirm which end of the linkage has failed before ordering.
6) Is it worth replacing just the top latch instead of the whole exit device?
That is exactly what this kit is for. When the top latch on a 33/35/98/99 Series device stops latching or engaging the head strike cleanly, the 050494 restores that function without pulling and replacing the entire device, rails and trim. For a property manager with several openings running the same Von Duprin devices, it keeps the rest of the hardware and the existing door prep untouched.
7) Is this Von Duprin latch kit rated for heavy traffic commercial use?
It is a Grade 1 commercial part. Grade 1 is the highest ANSI/BHMA durability tier for door hardware, which is what you want on school corridors, hospital wings, office stairwells and other high-cycle openings. It is a commercial component, not something meant for residential doors.
8) What is the top latch on an exit device actually doing, and how do I know mine has failed?
On a vertical rod device, the top latch is the assembly at the head of the door that engages the strike in the frame when the push rail returns. Push the rail and the rod pulls the top latch clear; release it and the latch should throw back up and catch. If the door swings shut without securing at the top, or the latch stays retracted, that assembly is the usual culprit, and the 050494 is the Non-EL replacement for it on 33/35/98/99 Series devices.
9) Do I need anything else besides the top latch kit to fix a vertical rod exit device?
The 050494 covers the top latch assembly itself. Other parts of a vertical rod system, the rods and the strikes, are separate items. If the rod is bent or the head strike is worn, the latch alone will not fix the opening. For reference on the range of parts, ZenSupply carries items like the Falcon 610061 concealed vertical top rod for Falcon 24 Series devices, which shows rods are ordered separately from latches on these systems.
10) Does a top latch kit like the Von Duprin 050494 cover a fire-rated opening?
No. The Von Duprin 050494 top latch kit is a non-electrified, Grade 1 commercial part carrying no fire rating. Among comparable exit device latch parts, the Accentra 60-7010-0049-999 for 7110/7120 devices also carries no fire rating, while the Accentra 60-7010-0050-999 is the component matched to the 7110F device. For a labeled opening, verify the complete device assembly against its own label rather than sourcing by latch part alone.
11) What looks like a substitute for the Von Duprin 050494 top latch kit but is not?
Several exit device service parts get confused with it. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch for T Series devices - a latch, but for a different device family. The Arrow 16RCR-27 is an SFIC rim housing for 24/25 Series, a cylinder component rather than a latch. The Falcon 4023 steel mullion and Falcon 525 aluminum mullion stabilizers address the opening between double doors, not the latching mechanism. Only the 050494 restores top latch function on a Von Duprin 33/35/98/99 Series device.
12) Is this top latch kit an OEM Von Duprin part or an aftermarket copy?
It is the genuine Von Duprin component, sourced from the manufacturer, so the fit, finish and function match the original assembly on the device. For institutional buyers standardizing on Von Duprin across a campus, that keeps the repair consistent with the rest of the hardware on the site.
13) Instead of replacing the top latch, can I use a mullion to fix a double door that won't secure?
They solve different problems. The Von Duprin 050494 top latch kit restores latch function inside a 33/35/98/99 Series exit device. If the issue is the free edge of a pair of doors rather than the device itself, the Falcon 4023 steel mullion provides a strike point for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers support mullion installations. Diagnose whether the latch is failing to project or the opening lacks a strike surface, then order accordingly.
