Von Duprin 050101 26D – Frequently Asked Questions

1) What does the Von Duprin 88CK-NL conversion kit actually change on an 88 Series exit device?
It converts an 88 Series device set up for TP (thumbpiece) or K (key) trim over to NL, night latch operation, where an outside key retracts the latch and there is no lever or thumbpiece on the pull side. You keep the existing device on the door and change only the trim function, so the rail, latch and door prep stay as they are.
2) Can I use the 88 Series TP/K to NL conversion kit on a fire rated door opening?
No. The 88 Series conversion kit carries no fire rating, so it should not go on a labeled fire door assembly. Fire exit hardware openings need components that are part of a listed assembly; a non-rated part in that assembly puts the label at risk.
3) Do I have to replace the whole exit device to switch from thumbpiece trim to night latch?
Not on an 88 Series. The 050101 kit reconfigures the existing device from TP or K trim to NL panic operation, so the device body stays on the door and only the trim function changes. That is the point of the part: change access on an opening without pulling and re-prepping the door.
4) My problem is a pair of doors with no center post, not the trim function - what should I be looking at instead of the 050101?
A mullion, not a trim conversion. The Von Duprin 050101 only changes an 88 Series device from TP or K trim over to NL panic operation on the door it is mounted to. For a double door opening that needs a removable center post so rim devices have something to latch into, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are the accessory that steadies a mullion in that opening. Those solve the opening geometry; the 050101 solves what the outside trim does.
5) Will an Accentra 7110/7120 top latch replacement component do the same job as the Von Duprin 050101 conversion kit?
No, they address different parts of an exit device. The Von Duprin 050101 is an 88 Series conversion kit that changes TP (thumbpiece) and K (key) trim configurations over to NL (night latch) panic operation, so it works on the outside trim function of the device. The Accentra 60-7010-0049-999 is a top latch replacement component for 7110/7120 exit devices, which is a latching part inside the device itself. If the door is a Von Duprin 88 Series and the goal is a different outside trim function, the 050101 is the part that does it; if a 7110 or 7120 device is not latching at the top, the Accentra top latch component is the part in question.
6) Is the Von Duprin 050101 conversion kit rated for a high traffic commercial door?
Grade 1, and commercial only. That is the heaviest duty rating in the ANSI/BHMA hardware grading scheme, which is what you want on school corridors, hospital egress doors and retail back-of-house where the device gets hit hundreds of times a day.
7) What finishes does the Von Duprin 050101 88 Series conversion kit come in?
Six: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome and 626 satin chrome. If you are matching a run of existing 88 Series openings in a building, 626 satin chrome is the usual commercial standard, but pick whichever matches the trim already on the doors so the converted opening does not stand out.
8) I need a key to get in from outside after converting to NL. Is a cylinder included with the 88CK-NL kit?
The kit is the conversion hardware that changes the 88 Series trim function from TP or K to NL. NL operation is keyed from the outside, so you need a rim cylinder with the right cam and keyway for your building's system. Order that separately and keyed to your existing system if you are standardizing a facility.
9) My tenant keeps propping the back door because staff get locked out. Is converting the 88 Series to NL the right fix?
It is the usual one. NL gives keyed entry from the outside on an exit device that would otherwise be exit-only or thumbpiece-operated, so staff with a key get back in and the door still free-egresses. If you instead want handle-and-lever entry for the general public, stay on a lever trim function rather than converting to NL.
10) The latch on the door is worn - does the 050101 replace it, or do I need a deadlatch part?
A conversion kit and a latch are separate repairs. The Von Duprin 050101 changes 88 Series TP and K trim over to NL panic operation and is classified as a replacement part for that line, but it is about the trim function rather than the latching point. When the latch itself is the worn item, the part called for is a latch component matched to the device brand and series - the Falcon 23981160 T Series 2-3/8 inch square corner deadlatch is that kind of part for Falcon T Series hardware. Confirm which symptom is being fixed, a function change or a worn latch, before ordering either.
11) I need a cylinder for night latch operation - is the Von Duprin 050101 the same thing as an Arrow 16RCR-27 rim housing?
They are not interchangeable. The Von Duprin 050101 is the 88 Series kit that converts TP and K trim to NL panic operation, changing how the outside of the device behaves. The Arrow 16RCR-27 is an SFIC rim housing for 6 or 7-pin small format interchangeable cores in the 24/25 Series, which is the shell that carries the core. A night latch conversion and the housing that holds the core are two separate line items, so an 88 Series opening being reconfigured to NL should be quoted with the 050101 for the trim function and the cylinder hardware specified separately to match the keying system in place.
12) Is there an equivalent conversion kit if the device on the door is a concealed vertical rod rather than an 88 Series rim device?
The Von Duprin 050101 is built for the 88 Series and converts TP and K trim to NL panic operation on that line, so it is specified by the device it is going on rather than by the opening. Concealed vertical rod hardware is serviced with its own rod and latch components - for example the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, in the 245 Series. Identify the device family stamped on the existing hardware first, because parts for a rim device and parts for a concealed vertical rod device are not shared.
13) Is there an equivalent trim conversion kit for a non Von Duprin exit device?
Not a direct one. Exit device trim conversion parts are series specific, and the 050101 is an 88 Series part. For other brands the comparable parts are the ones built to that line: Arrow's 16RCR-27 SFIC rim housing for the 24/25 Series, or Falcon's 610061 concealed vertical top rod for F-25-C and F-25-CWDC devices in the 24 Series Monarch line. Identify your device series first, then order the part built for it.
