Von Duprin 50105 – Frequently Asked Questions

1) What does the Von Duprin 050105 NL conversion kit actually do to a 55 Series exit device?
The 050105 converts a Von Duprin 55 Series exit device to an NL (night latch) configuration, so the device can be operated from the outside through pull trim instead of running as an exit-only device. It's a genuine Von Duprin replacement part for the 55 Series platform, and the outside trim itself is ordered separately.
2) Does the Von Duprin 050105 kit come with the outside pull trim, or do I need to order that too?
Trim is not included. The 050105 gives you the conversion hardware for the device itself; you order the outside trim separately, which also lets you pick the trim style and finish to match the rest of the openings in the building. Budget both line items on the purchase order or the job will stall at install.
3) Will the 050105 conversion kit fit any Von Duprin exit device, or only certain ones?
Only the Von Duprin 55 Series. The kit is built for that platform specifically, so it will not drop onto a 98/99, 33A/35A, or any other Von Duprin family. Check the device stamping or the original submittal before ordering.
4) I need key access from outside on my 55 Series exit device. Is a rim cylinder housing like the Arrow 16RCR-27 an alternative to the 050105?
They solve different halves of the same job. The Von Duprin 050105 is the NL conversion kit that prepares a 55 Series exit device for night latch operation, with the trim ordered separately. The Arrow 16RCR-27 is an SFIC rim housing for 6 or 7 pin small format interchangeable cores, built for the Arrow 24/25 Series. It houses a core rather than converting a device, and it is not a Von Duprin 55 Series part. A locksmith keying a 55 Series opening orders the 050105 plus the matching Von Duprin trim and cylinder, not an Arrow housing.
5) I need a replacement part for an exit device but it isn't a Von Duprin 55 Series - what else is out there?
The 050105 is Von Duprin 55 Series only, so for other platforms you want the matching brand's own part. For Accentra 7110/7120 devices there's the 7110/7120 top latch replacement component, and a separate version for the fire rated 7110F. Falcon T Series devices take the 2-3/8 inch square corner deadlatch replacement, and Falcon 24 Series Monarch concealed vertical devices (F-25-C and F-25-CWDC) use the 610061 top rod. Exit device parts do not cross brands.
6) I'm converting a pair of doors to keyed outside access - is the NL kit all I need?
On a pair, the NL conversion handles how each device is operated from outside, but it does nothing about securing the gap between the two leaves. If your devices are rim type, you still need a removable mullion, such as the Falcon 4023 steel mullion for double door exit device applications, plus Falcon 525 aluminum mullion stabilizers if the mullion needs them. Surface or concealed vertical rod devices latch top and bottom and do not need a mullion.
7) Does the Von Duprin 050105 kit include a cylinder for the night latch trim?
No cylinder comes with the 050105. The kit handles the device-side conversion; the cylinder goes with the outside trim, which is a separate order. Locksmiths standardizing a building will want the cylinder specified in the same keyway and keying system as the rest of the openings.
8) Can I use the Von Duprin 050105 on a fire rated opening?
The Von Duprin 050105 55 Series NL conversion kit carries a fire rating of No, so it should not be specified where the opening requires fire labeled exit hardware. Among the comparable exit device components, the Accentra 60-7010-0050-999 top latch for the 7110F device also carries a fire rating of No. For any fire rated opening, confirm the full device and trim assembly against the manufacturer's listing before ordering conversion parts.
9) Is the Von Duprin 050105 NL conversion kit the same kind of part as an exit device top latch replacement like the Accentra 60-7010-0049-999?
No. The Von Duprin 050105 is an NL conversion kit for the 55 Series exit device platform, a replacement part that changes how the device is configured so it can work with outside trim, which is ordered separately. The Accentra 60-7010-0049-999 is a top latch replacement component for the Accentra 7110/7120 exit devices, meaning it restores a latching component rather than converting the device function. If a 55 Series device is latching correctly and you only need outside key access through trim, the 050105 is the conversion part; if an Accentra 7110 or 7120 has a failed top latch, the Accentra component is the matching repair item.
10) I have a pair of doors and want key entry from outside. Do I need the 050105 or a mullion?
That depends on how the pair is latching. The Von Duprin 050105 NL conversion kit changes a 55 Series exit device so it can accept separately ordered trim for outside access. A removable mullion such as the Falcon 4023 steel mullion gives a pair of doors a fixed strike point so rim devices can be used on both leaves, and the Falcon 525 aluminum mullion stabilizers are accessories for mullion installations. A mullion addresses the opening's latching arrangement; the 050105 addresses outside trim operation on the device itself, so a double door job may call for both.
11) My concealed vertical rod device is not latching at the top. Will the 050105 fix it?
No. The Von Duprin 050105 is an NL conversion kit for the 55 Series platform and is classified as a replacement part for configuration changes, not a latching repair. A top latching failure on a concealed vertical rod device is addressed by rod and latch components, such as the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices. Identify the device series stamped on the exit device before ordering, since rod parts are series specific.
12) Where can I find the full Von Duprin 55 Series specs to confirm this conversion kit is right for my device?
Von Duprin publishes a 55 Series catalog covering the device platform this kit belongs to, and it's the reference for confirming your device model, function, and trim options before you order the 050105 and its separate trim.
13) What is the difference between the Von Duprin 050105 and a deadlatch replacement part like the Falcon 23981160?
The Von Duprin 050105 is a Grade 1 commercial NL conversion kit for the 55 Series exit device platform, used to adapt an installed device for night latch trim operation. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, which is a latch component that swaps into the door edge. One changes device function, the other replaces a worn latching part, and each is tied to its own manufacturer's series, so they are not interchangeable.
