Von Duprin 50623 – Frequently Asked Questions

1) Will the Von Duprin 050623 extension rod kit work with a 33A or 35A exit device?
Yes. The 050623 extension rod kit is built for the Von Duprin 33, 35 and 48 Series exit devices, so it suits 33A and 35A vertical rod applications within that family. If the device on your door is another Von Duprin series, this is not the rod kit for it.
2) I have a pair of doors with no mullion and the rods won't reach the header. Is a rod kit the fix?
On a vertical rod device, yes, extending the rod is the normal fix when the top latch won't reach the strike on a taller opening, and the 050623 handles that on 33/35/48 Series devices. If instead you're running rim devices on a pair and need something to latch against, a rod kit won't help you; that job needs a mullion, such as the Falcon 4023 steel mullion for double door exit device applications.
3) Is there a vertical rod part for Falcon concealed vertical rod exit devices instead of the Von Duprin 050623?
For a Falcon concealed vertical rod opening, the Falcon 610061 is a 24 Series Monarch concealed vertical top rod made for the F-25-C and F-25-CWDC exit devices. The Von Duprin 050623 extension rod kit is built for the Von Duprin 33, 35 and 48 Series exit devices, so the two are not interchangeable - match the rod to the device brand and series already on the door.
4) Do I need an extension rod kit for a tall door, or a whole new exit device?
If the exit device itself is sound and only the door height is the problem, the extension rod kit is the part you want. It's an adjustable rod assembly sold as a replacement component for 33/35/48 Series devices, so you keep the existing chassis and top/bottom latches and just change the rod length. You'd only replace the device if the chassis, latch or trim is also failing.
5) Is the Von Duprin 050623 rod kit heavy duty enough for a school or hospital entrance?
It's a Grade 1 commercial component, which is the heavy-duty tier used in high traffic openings such as schools, hospitals, offices and government buildings. It is a commercial part, not a residential one.
6) Can I use the Von Duprin 050623 on a fire rated exit device opening?
The Von Duprin 050623 extension rod kit carries no fire rating, and neither do the Accentra 7110/7120 and 7110F top latch replacement components. On a labeled fire door, the rod and latch components must match the device manufacturer's fire listing for that assembly, so confirm the device label before substituting any rod or latch part.
7) I need to secure a pair of doors without vertical rods - what do I use instead of an extension rod kit?
If the goal is a double door opening rather than repairing a rod device, a removable mullion is the different approach: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are made for use with exit devices. The Von Duprin 050623 is a replacement extension rod kit for 33/35/48 Series devices, so it addresses rod length on an existing vertical rod device rather than changing how the pair of doors is secured.
8) My top latch is worn on an exit device - will the Von Duprin 050623 fix that?
No. The 050623 is an extension rod kit, a replacement part that addresses rod length on Von Duprin 33, 35 and 48 Series devices. A worn latch is a separate component: for Accentra devices, the 60-7010-0049-999 is a top latch replacement component for the 7110/7120 and the 60-7010-0050-999 is the top latch replacement for the 7110F. Identify whether the fault is in the rod or the latch before ordering.
9) Is the Von Duprin 050623 a genuine Von Duprin part or an aftermarket rod?
It's Von Duprin's own part number 050623, an OEM replacement component for their 33, 35 and 48 Series exit devices, ordered as a single model with no finish or handing options to specify.
10) What is the difference between the Von Duprin 050623 and a Falcon T Series deadlatch part?
They serve different devices. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series. The Von Duprin 050623 is an adjustable extension rod kit for Von Duprin 33, 35 and 48 Series exit devices and is a Grade 1 commercial component. One is a latching mechanism for a T Series lock, the other is rod stock for a vertical rod exit device.
