Von Duprin 50370 – Frequently Asked Questions

1) Which Von Duprin exit devices does the 050370 bottom bracket guide fit?
The 050370 bottom bracket guide is built for the Von Duprin 55 Series, specifically the 5547 and 47WDC exit devices. It is a genuine Von Duprin replacement component for those assemblies, so if the device on your door is a different Von Duprin series or a different manufacturer's device, this is not the part for it.
2) Do I need to replace the whole exit device, or can I just swap the bottom bracket guide?
If the device body and latching are sound and the problem is alignment or drag at the bottom, the guide alone is the repair. That is the point of stocking the 050370 as a separate component: you keep the existing 5547 or 47WDC on the door, cut the downtime, and avoid re-prepping the door for a new device.
3) Can a Falcon 610061 top rod be used in place of the Von Duprin 050370 bottom bracket guide?
No. The Von Duprin 050370 is a bottom bracket guide for 55 Series 5547 and 47WDC exit devices, so it sits at the bottom of a concealed vertical rod device and keeps the rod and bottom bracket aligned. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, which is a different brand's device line and a top-of-door rod rather than a bottom guide. They are not interchangeable in either direction.
4) What does the bottom bracket guide actually do on a 55 Series exit device?
It sits at the bottom of the device and keeps the moving assembly aligned and traveling straight. When that guide is worn or bent, you get binding, a rod or latch that does not return cleanly, and a device that feels sloppy on the push. Replacing the guide restores alignment without pulling and replacing the whole 5547 or 47WDC device.
5) Is this a genuine Von Duprin part or an aftermarket copy?
Genuine Von Duprin. The 050370 is an authentic factory replacement component from the 55 Series product line, which matters on exit devices because a slightly off bracket will misalign the whole assembly.
6) My pair of doors keeps going out of alignment. Is a bottom bracket guide the fix, or do I need a mullion?
Two different problems. The 050370 corrects travel and alignment inside a single 5547 or 47WDC device. If the issue is that the two leaves of a pair have nothing to latch against in the middle, that is a mullion question, and the Falcon 4023 steel mullion is the part for double door exit device openings, with the Falcon 525 aluminum mullion stabilizers available where the mullion itself needs steadying.
7) I need a replacement latch part for an exit device, not a bottom guide. What are the options?
The Von Duprin 050370 is a bottom bracket guide and does nothing for latching. If the latch is the failed component, the Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110 and 7120 devices, and the Accentra 60-7010-0050-999 covers the 7110F. For a Falcon T Series rim device, the 23981160 is a 2-3/8 inch square corner deadlatch replacement part. Match the part to the device brand and model already on the door.
8) My 55 Series device is on a pair of doors with no mullion. Is the 050370 what I need to stabilize the opening?
No. The 050370 is a replacement bottom bracket guide for 5547 and 47WDC devices and only addresses alignment within the device itself. For a double door opening that needs a removable center post, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are the accessory for steadying a mullion. Those are opening-level parts, not device internals.
9) Will the Arrow 16RCR-27 rim housing work with a Von Duprin 55 Series exit device?
They solve different problems. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing from the Arrow 24/25 Series, a cylinder housing used for keyed access. The Von Duprin 050370 is a mechanical bottom bracket guide for 55 Series 5547 and 47WDC devices and has no keying function. Order the 050370 for a device alignment or bracket issue and treat cylinder hardware as a separate specification.
