Von Duprin 24090110 – Frequently Asked Questions

1) What does the Von Duprin 49 top latch assembly actually do on a 98 or 99 Series exit device?
On a Von Duprin surface vertical rod device, the 49 top latch is the piece at the head of the door that the top rod drives. It's the part that engages the strike in the frame header when the door closes and releases when the pushpad is depressed. If a vertical rod device is no longer catching at the top, or the top latch is worn, bent, or the door drifts open at the head, this assembly is the component that gets replaced. It is a replacement part, not a complete device, so the pushpad, rods, and bottom latch stay as installed.
2) Will the Von Duprin 24090110 top latch fit my 33A exit device, or is it only for 98/99?
It covers all four families. The 24090110 49 top latch assembly is built for Von Duprin 33A, 35, 98, and 99 Series exit devices, which is one of the reasons it's a common shelf item for anyone maintaining a mixed building. If your device is stamped 33A, 35, 98, or 99, this is the top latch for it.
3) Can I use the Von Duprin 49 top latch on a fire rated exit device?
No. The 24090110 49 top latch assembly carries no fire rating. Fire rated vertical rod openings use fire labeled device components, and swapping a non-rated part into a labeled assembly voids the label on that opening. If the door has a fire label and the device is an F-prefix Von Duprin, source the fire rated top latch for that device instead.
4) I have Accentra exit devices, not Von Duprin. Will this top latch work on those?
No, and don't try it. The 24090110 is dimensioned to Von Duprin 33A, 35, 98, and 99 chassis and rod geometry. For Accentra devices ZenSupply carries the matching parts by device family: the 7110/7120 exit device top latch replacement component, and a separate top latch component for the 7110F. Exit device latch assemblies are not interchangeable across manufacturers, so match the part to the brand stamped on the device.
5) My concealed vertical rod device latches at the top but the rod is bent - is the 24090110 top latch assembly the part I need?
Not necessarily. The Von Duprin 24090110 49 top latch assembly is the latch itself, for the 33A, 35, 98 and 99 Series devices; it does not include the vertical rod that drives it. If the rod is the damaged piece, the part class you want is a vertical rod, such as the Falcon 610061 24 Series Monarch concealed vertical top rod for the F-25-C and F-25-CWDC exit devices, ordered in the version that matches your own device family. Diagnose which of the two failed before ordering: a latch that will not retract points at the latch assembly, a latch that retracts but does not reach the strike points at the rod.
6) Is a Von Duprin exit device top latch rated for a high traffic commercial door?
Grade 1 and specified for commercial use, which is the top performance tier for door hardware and the one written into most institutional specs. Schools, hospitals, office towers, and municipal buildings all run Von Duprin vertical rod devices on their heaviest traffic egress doors, and the 49 top latch is built to that same standard. For an MRO buyer standardizing across a facility, it's the same part number across 33A, 35, 98, and 99 devices.
7) My exit device latches at the top and bottom of the door but I don't know which part failed. Do I need the top latch or a new rod?
Diagnose by where the motion stops. If the pushpad depresses and the top rod moves but the latch at the head doesn't retract or won't re-engage the header strike, the fault is in the top latch assembly and the 24090110 is the fix on a 33A, 35, 98, or 99 device. If the pad moves and the rod doesn't, or the rod is bent or disconnected, you need rod hardware rather than the latch. A worn latch usually shows as a door that closes but doesn't stay secured at the head.
8) Is the Von Duprin 49 top latch the same thing as a concealed vertical rod top latch?
Different part, different device. The 49 is a surface vertical rod top latch for Von Duprin 33A, 35, 98, and 99 devices, where the rods run on the face of the door. Concealed vertical rod devices route their rods inside the door and use their own rod and latch hardware, for example the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices. Look at the door: rods visible on the push side means surface, nothing visible means concealed.
9) I keep replacing top latches on a pair of doors. Would a mullion be a better fix?
Sometimes, yes. Vertical rod devices on a pair take abuse at the head and threshold, and if the openings are getting hit hard, converting to rim devices on a removable mullion moves the latching to the mullion at mid-height where there's far less to damage. ZenSupply carries the Falcon 4023 steel mullion for double door exit device applications, plus Falcon 525 aluminum mullion stabilizers. That's a device change, not a parts swap, so if you just need the existing Von Duprin 33A, 35, 98, or 99 device working again, the 24090110 top latch is the direct repair.
10) How do I order the right Von Duprin top latch part number?
Ask for Von Duprin part 24090110, the 49 top latch assembly. There are no finish or handing options to specify on it, one part number covers 33A, 35, 98, and 99 Series devices. What you do need to confirm before ordering is that the opening is not fire rated, since this component is non-rated, and that the device is surface vertical rod rather than rim or mortise.
11) Accentra sells two top latch components, 60-7010-0049-999 and 60-7010-0050-999 - what is the difference and does either cross to Von Duprin?
The Accentra 60-7010-0049-999 is the top latch replacement component for the 7110/7120 exit device, and the 60-7010-0050-999 is the top latch replacement component for the 7110F. Both carry a fire rating of No. Neither crosses to Von Duprin hardware - the Von Duprin 24090110 49 top latch assembly is the top latch part for the 33A, 35, 98 and 99 Series devices. A locksmith carrying all three on the truck should tag them by device family, since the parts look similar in the bin and are not interchangeable across brands.
12) Is a Falcon deadlatch or SFIC rim housing a substitute for a Von Duprin exit device top latch?
No - those are different parts that share the word latch or the exit device shelf. The Von Duprin 24090110 49 top latch assembly is the top latching mechanism for 33A, 35, 98 and 99 Series exit devices. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the T Series, which is a latch for a T Series lock rather than a vertical rod device. The Arrow 16RCR-27 is an SFIC rim housing for 6 and 7-pin cores in the 24/25 Series - a cylinder housing, not a latch at all. A distributor cross-referencing by keyword will surface all three; only the 24090110 restores top latching on the Von Duprin series listed.
13) The pair of doors keeps failing at the top latch - should I replace the latch assembly or change the opening to a mullion?
Both are valid ways to secure a pair, and they solve different problems. Replacing the top latch with the Von Duprin 24090110 49 top latch assembly keeps the existing 33A, 35, 98 or 99 Series vertical rod devices and the clear opening between the leaves. Converting to a mullion, such as the Falcon 4023 steel mullion for double door exit device applications, moves the latching to a center post and lets both leaves run rim devices instead of vertical rods, at the cost of a post in the opening; Falcon 525 aluminum mullion stabilizers are the accessory that steadies that post. Facilities that need the full clear width for carts and gurneys generally stay with vertical rods and replace the latch.
14) We standardize MRO stock across a campus - can one top latch assembly cover all our exit devices?
Only where the devices share a family. The Von Duprin 24090110 49 top latch assembly is a Grade 1 commercial replacement part covering the 33A, 35, 98 and 99 Series, which is a wide span of Von Duprin devices from one shelf position. Openings running Accentra hardware need their own parts - the 60-7010-0049-999 for 7110/7120 devices and the 60-7010-0050-999 for the 7110F. For a mixed campus, the practical stocking plan is one Von Duprin top latch assembly plus the matching Accentra component for whichever of those two device models is installed.
15) Do I need to order a header strike with the Von Duprin 49 top latch assembly?
Not necessarily. The 24090110 is the latch assembly that mounts on the door; the strike in the frame header is separate hardware and usually stays put if it isn't damaged. Inspect it while you have the device apart, because a chewed or misaligned strike is often what killed the latch in the first place, and putting a new latch against a bad strike gets you back on a ladder.
