Von Duprin 50458 – Frequently Asked Questions

1) Can I use a Falcon bottom or top rod instead of the Von Duprin 8847-F rod?
No. Rods are not cross-brand parts. The Falcon 610061 is a concealed vertical top rod for Falcon 24 Series Monarch F-25-C and F-25-CWDC devices, a different brand, a different device family, and the top rod rather than the bottom. Fitting it to a Von Duprin 55/88 Series device is not a substitution. For a Von Duprin 55/88 vertical rod device, the bottom rod has to be the Von Duprin 8847-F kit.
2) What is the Falcon equivalent of the Von Duprin 8847-F bottom rod kit for a concealed vertical rod exit device?
There is no one-for-one Falcon copy of the 050458, because vertical rod parts are cut and drilled to the device family they belong to. The closest Falcon vertical rod component is the Falcon 610061, a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices. Two differences decide it: the 610061 is a top rod, where the Von Duprin 050458 8847-F kit is the bottom rod assembly, and the 610061 belongs to the Falcon 245 Series platform while the 050458 is built for the Von Duprin 55/88 Series. Match the rod to the device stamped on the pushbar, not to the rod it visually resembles.
3) Is the Von Duprin 050458 bottom rod kit a genuine Von Duprin part or an aftermarket rod?
Genuine Von Duprin, model 8847-F, sold as a factory replacement part for the 55/88 Series. For a facility standardized on Von Duprin, that matters on two fronts: the device keeps its original manufacturer specification, and a locksmith servicing the opening later is working with the same part the device was built with rather than a substituted rod.
4) Is the 8847-F bottom rod kit rated for high-traffic commercial doors?
Grade 1 and commercial-rated, which is the level specified for high-cycle openings such as school corridors, hospital egress doors, office lobbies and warehouse exits. Grade 1 is the top ANSI/BHMA performance tier for door hardware, so replacing a worn bottom rod with this kit keeps the device at the grade the opening was originally specified to.
5) My vertical rod device keeps failing at the bottom on a pair of doors. Should I keep repairing it or switch to a mullion?
Both are real options. Replacing the bottom rod with the Von Duprin 8847-F kit keeps the existing 55/88 Series vertical rod setup, which latches at the head and the threshold and leaves the opening clear with no post in the middle. If the bottom latch is failing repeatedly because of floor debris, settling or heavy abuse, the other route is converting the pair to rim devices with a removable mullion, such as the Falcon 4023 steel mullion, which moves the latching off the floor entirely at the cost of a post in the opening. That conversion means new devices, not just a rod.
6) If the top latch on my exit device is the part that failed, is the 8847-F bottom rod kit what I need?
No, that is the wrong end of the device. The Von Duprin 8847-F kit covers the bottom rod only. A failed top latch is a separate component, and on other brands it is ordered as its own part, for example the Accentra 7110/7120 exit device top latch replacement component. Diagnose which end is not latching first: if the door catches at the head but drags free at the floor, the bottom rod is the problem and this kit is correct.
7) Can an Accentra exit device top latch be used in place of a Von Duprin 8847-F bottom rod kit?
No. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, and the Accentra 60-7010-0050-999 is the top latch component for the 7110F. Both are top-of-door latching parts for Accentra devices; the Von Duprin 050458 8847-F kit is the bottom rod assembly for Von Duprin 55/88 Series devices. Neither the position on the door nor the device platform lines up, so they are not interchangeable. If the bottom latch on a 55/88 device is not throwing, the 050458 is the bottom-end part; a failing top latch is a separate component entirely.
8) Is there a simpler alternative to replacing vertical rods on a pair of doors?
Yes, if the opening can be converted. Vertical rod hardware latches into the head and the floor, which is what makes the bottom rod a wear item in the first place. A removable mullion lets a pair run rim devices that latch into the mullion instead: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers support mullion installations. That is a hardware change to the opening, not a parts swap. If the existing Von Duprin 55/88 Series vertical rod devices are staying, the 050458 8847-F bottom rod kit is the component that restores bottom latching on the device already hung.
9) My exit device will not stay latched. Do I need a bottom rod kit or a deadlatch part?
It depends on where the device latches. On a vertical rod device, the latching happens at the top and bottom of the door, and the Von Duprin 050458 8847-F bottom rod kit is the bottom rod assembly for Von Duprin 55/88 Series devices. On a rim or mortise-style latch, the latch and deadlatching plunger sit in the latch case at the strike edge, which is what a part like the Falcon 23981160 2-3/8 inch square corner deadlatch for the Falcon T Series replaces. Check whether the door latches into the frame head and threshold or into a strike on the jamb before ordering either one.
10) Does an SFIC rim housing like the Arrow 16RCR-27 have anything to do with a bottom rod kit?
No, they solve different problems on the same door. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the Arrow 24/25 Series, the cylinder side of the device that controls keyed access from outside. The Von Duprin 050458 8847-F bottom rod kit is the mechanical bottom rod assembly for Von Duprin 55/88 Series devices and governs whether the door latches at the bottom. A device that will not relock at the floor needs the rod kit; a device where the key will not retract the latch needs attention at the cylinder.
