Von Duprin 50520 – Frequently Asked Questions

1) Which Von Duprin exit devices does the 050520 bottom rod kit fit?
The 050520 bottom rod kit is built for Von Duprin 33 and 35 Series devices using 47A and 48A vertical rod trim. It is not a universal rod, so if the device on the door is a different Von Duprin series or a rim device, this kit is the wrong part.
2) Do I have to replace the whole exit device if the bottom rod is bent or missing?
Not on a 33 or 35 Series device with 47A/48A vertical rod hardware. The 050520 supplies the bottom rod components so you can restore the bottom latching point and leave the chassis, top rod and trim in place. That is usually the difference between a service call and a full device swap.
3) I have a Falcon vertical rod device, not Von Duprin. Will this rod kit work?
No. The 050520 is cut and drilled for Von Duprin 33/35 Series 47A/48A hardware and rods are not interchangeable between brands. For Falcon concealed vertical rod devices we carry the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices.
4) Is the Falcon 610061 vertical rod a substitute for the Von Duprin 050520 bottom rod kit?
No. The Falcon 610061 is a 24 Series Monarch concealed vertical TOP rod made for Falcon F-25-C and F-25-CWDC exit devices, so it addresses the upper half of a different manufacturer's concealed vertical rod device. The Von Duprin 050520 is a bottom rod kit for Von Duprin 33 and 35 Series 47A and 48A exit devices. Rod kits are cut and drilled to the parent device's geometry, so a Falcon top rod will not serve a Von Duprin bottom rod opening. If the Falcon device is the one on the door and the top rod is what failed, the 610061 is the correct direction.
5) My exit device latching problem is at the top of the door, not the bottom. What part should I be looking at instead of the 050520 bottom rod kit?
The 050520 covers bottom rod components on Von Duprin 33 and 35 Series 47A/48A devices, so it will not correct a top latch fault. On the top end of a vertical rod device, the equivalent service items are top rods and top latches: Falcon offers the 610061 concealed vertical top rod for F-25-C and F-25-CWDC devices in the 24 Series Monarch line, and Accentra offers top latch replacement components for its 7110/7120 devices under 60-7010-0049-999 and for the 7110F under 60-7010-0050-999. Match the replacement to the brand and series stamped on the device you already have rather than to the symptom alone.
6) Is the Von Duprin 050520 rod kit rated for high traffic commercial doors?
It is a Grade 1 commercial part, which is the highest ANSI/BHMA performance tier and the level normally specified for school corridors, hospitals, and high traffic office entries.
7) My pair of doors keeps having trouble at the bottom latch. Should I fix the rod or go less bottom rod with a mullion?
Two different fixes. Replacing the bottom rod with the 050520 keeps the existing 33/35 Series 47A/48A vertical rod arrangement latching at both head and threshold, which is what lets a pair of doors secure without a center post. If the bottom latch is the recurring failure point because of floor debris or wear, the alternative is a mullion between the leaves, such as the Falcon 4023 steel mullion for double door exit device applications, with the Falcon 525 aluminum mullion stabilizers where the mullion needs bracing.
8) Can I use the Von Duprin 050520 bottom rod kit on a fire-rated opening?
The Von Duprin 050520 bottom rod kit is not fire rated. Among the comparable exit device service parts, the Accentra 7110/7120 top latch component (60-7010-0049-999) is likewise not fire rated, while the Accentra 60-7010-0050-999 serves the 7110F device. On a labeled opening the whole device assembly has to remain as listed, so confirm the rating path of the complete device with the authority having jurisdiction before swapping any rod or latch component.
9) Instead of replacing bottom rods on a pair of doors, can I use a mullion?
That is a different approach rather than a direct swap. The Von Duprin 050520 restores bottom rod components on existing 33 and 35 Series 47A/48A vertical rod devices. Converting a double door to a mullion arrangement means the pair carries rim devices against a center post instead, using something like the Falcon 4023 steel mullion for double door exit device applications, with the Falcon 525 aluminum mullion stabilizers available for exit device mullion use. That route changes the device type, the strike prep, and the fire and egress documentation for the opening, so it is a redesign of the pair, not a parts repair.
10) What is the difference between the Von Duprin 050520 and a deadlatch or cylinder housing replacement part?
They repair different subsystems. The Von Duprin 050520 is a bottom rod kit, a Grade 1 commercial installation accessory for 33 and 35 Series 47A/48A exit devices, and it deals with the vertical rod that drives the bottom latch. A deadlatch replacement such as the Falcon 23981160, a 2-3/8 inch square corner deadlatch part in the T Series, replaces the latching mechanism itself in a latch-based lock, and a cylinder housing such as the Arrow 16RCR-27 SFIC rim housing for 6/7-pin cores in the 24/25 Series handles keyed access on the outside of the door. If the device latches fine but will not key, the housing side is where to look; if the bottom of the door will not secure, the rod kit is.
11) Is the 050520 a genuine Von Duprin part or an aftermarket rod?
Genuine Von Duprin, sold under model number 050520 within the Von Duprin exit device parts line. That matters on 33/35 Series devices because rod length and end fittings are specific to the manufacturer's own hardware.
