Von Duprin 050186 26D – Frequently Asked Questions

1) Will the Von Duprin 050186 center case kit work on a right hand door?
No. The 050186 5575 center case kit is built for Left Hand Reverse openings only, and handing on a center case is not field-reversible. Stand outside the door on the pull side: if the hinges are on your right and the door swings toward you, that is LHR and this is the part. Any other handing needs the matching center case kit for that hand.
2) What Von Duprin exit devices does the 050186 center case kit fit?
It is a genuine Von Duprin replacement center case for 55 Series exit devices, including the 5575 device. It is a component kit, not a complete device, so you are rebuilding an existing 55 Series unit rather than replacing the whole thing. Confirm the device on the door is a 55 Series before ordering, since center cases do not cross between Von Duprin series.
3) Is the Accentra 7110/7120 top latch a substitute for a Von Duprin 5575 center case kit?
No. The Von Duprin 050186 is a 5575 center case kit, the mechanism housing at the center of a 55 Series exit device, and it is supplied in a Left Hand Reverse configuration. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, so it addresses the latching point at the head of the door on a different manufacturer's device rather than the center case. The two parts sit in different positions on different device families and are not interchangeable in either direction.
4) The latch on my Falcon T Series device is failing. Can I use a Von Duprin center case kit?
No. The Von Duprin 050186 5575 center case kit is built for Von Duprin 55 Series exit devices and is a Grade 1 commercial component. For a Falcon T Series device, the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part in the T Series. Stay within the device family when ordering replacement components, since center cases and latches are cut to each manufacturer's own chassis.
5) What finishes does the Von Duprin 5575 center case kit come in?
Seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, and 693 black painted. If you are repairing one device in a run of openings, match the finish code stamped on the existing devices rather than eyeballing it. 626 satin chrome and 613 oil rubbed bronze are the two most common on commercial exit hardware.
6) Is it worth rebuilding a Von Duprin 55 Series exit device or should I replace the whole unit?
If the rail, end cap, and mounting prep are sound and the failure is in the center case (the pushbar mechanism that drives the latch), the 050186 kit restores function without touching the door prep or re-drilling. Replacing the full device means new prep, new trim coordination, and re-keying if there is cylinder dogging. A center case kit is the repair path a locksmith takes first on a Grade 1 device that is otherwise intact.
7) Is the Von Duprin 050186 rated for a high traffic commercial door?
Grade 1, commercial. That is the top ANSI/BHMA durability tier for door hardware and the level specified for schools, hospitals, and other openings that see constant use. It is not a residential-duty part.
8) I need a replacement part for an exit device but mine is not a Von Duprin. What are my options?
Center cases are brand and series specific, so a Von Duprin part will not go into another maker's device. For Accentra 7110 and 7120 devices there is a top latch replacement component, with a separate version for the fire-rated 7110F. Falcon T Series takes a 2-3/8 inch square corner deadlatch, and Falcon 24 Series Monarch concealed vertical devices (F-25-C and F-25-CWDC) use the 610061 top rod. Match the part to the exact device series stamped on your hardware.
9) My exit device problem is at the top of the door, not the pushbar. Is the 050186 the right part?
Probably not. The 050186 is the center case, the housing under the pushbar that drives the latching. If the trouble is a top latch or a vertical rod not retracting, you want the latching component instead. Accentra 7110 and 7120 devices have a dedicated top latch replacement, and Falcon 24 Series Monarch concealed vertical devices use the 610061 top rod. Diagnose which end of the device has failed before ordering, because the center case and the latch assembly are separate parts.
10) What part do I order if the problem is a concealed vertical top rod rather than the exit device center case?
A center case kit such as the Von Duprin 050186 for 55 Series devices replaces the mechanism housing, not the rod. If the fault is in the concealed vertical rod at the top of the door on a Falcon 24 Series Monarch device, the Falcon 610061 is the concealed vertical top rod for F-25-C and F-25-CWDC exit devices. Identify which component actually failed before ordering, since a center case and a vertical rod restore different parts of the device's travel.
11) Does the Von Duprin 050186 center case kit carry a fire rating, and how does that compare to other exit device replacement components?
The Von Duprin 050186 5575 center case kit is not fire rated. Among comparable exit device replacement components, the Accentra 7110F top latch component, part 60-7010-0050-999, is likewise not fire rated. If the opening is a labeled fire door, confirm the rating of the complete device assembly with the specifier rather than assuming a component carries the label.
12) I need to secure a pair of doors with exit devices, not repair one device. Is a center case kit what I want?
No. The Von Duprin 050186 5575 center case kit is a replacement component for a single 55 Series exit device. For a double door opening, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are exit device accessories used with mullions. Those address how the pair of doors is secured at the opening; the center case kit addresses the internal mechanism of one device.
13) Will an SFIC rim housing let me rekey an exit device instead of replacing the center case?
Those solve different problems. The Von Duprin 050186 is a 5575 center case kit for 55 Series exit devices and governs the mechanical operation of the device, not the keying. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the Arrow 24/25 Series and is what accepts a small format interchangeable core for cylinder work. A worn or damaged center case is replaced with the center case kit; a change of keying is handled at the cylinder housing.
14) Do I need anything else to install a Von Duprin 5575 center case kit?
The kit is the center case assembly itself and calls for professional installation. Plan on the existing rail, end cap, latch assembly, and any trim or cylinder staying in place and being reused, so verify those are serviceable before you pull the device apart. Handing is fixed at LHR, so the one thing you cannot correct on site is ordering the wrong hand.
15) I have a pair of doors with exit devices. Does the center case kit handle the mullion side too?
No, that is a different part entirely. The 050186 rebuilds the mechanism inside one device. If the pair needs a removable center post so rim devices have something to latch into, that is a mullion, such as the Falcon 4023 steel mullion for double door exit device applications, with Falcon 525 aluminum mullion stabilizers as the related accessory. A center case repair and a mullion solve unrelated problems on the same opening.
