Von Duprin 109872 – Frequently Asked Questions

1) What is the Von Duprin 109872 spiral cam sub-assembly and where does it go?
The 109872 is an internal cam component that sits inside a Von Duprin 210K Series trim assembly. It's the piece that translates lever or knob rotation into the motion that retracts the exit device latch, so when the outside trim turns but the device doesn't release, this is the part you replace rather than buying a whole new trim.
2) Will the Von Duprin 109872 cam fit trim other than the 210K Series?
No. The 109872 spiral cam is built for Von Duprin 210K Series trim only. Von Duprin trim families use different cam geometry, so a cam pulled for a 210K won't service other trim lines. Confirm the trim you're repairing is a 210K before ordering this part.
3) My exit device trim lever turns freely but the latch doesn't retract. Is the spiral cam the problem?
On a 210K trim, that symptom points at the cam. The spiral cam is the linkage between the lever and the device's actuating mechanism, so a worn or failed cam lets the lever spin without moving anything downstream. The 109872 replaces that sub-assembly. If the lever itself is loose in the rose or the device chassis is binding, the fault is elsewhere in the trim or device.
4) Is the Von Duprin 109872 a genuine OEM part or aftermarket?
Genuine Von Duprin. It's the factory sub-assembly for 210K trim, which matters on institutional openings where a repair with non-OEM internals can put the exit hardware outside its listed configuration.
5) Is the Von Duprin 109872 cam rated for high-traffic commercial doors?
It's a Grade 1, heavy duty commercial component. That's the top ANSI/BHMA durability tier for door hardware, which is what you want on school corridors, hospital wings, and other openings cycled hundreds of times a day.
6) Do I need to remove the whole exit device to replace the 210K trim cam?
No, the work is on the trim side. The 109872 is an internal trim component, so the repair is pulling the outside trim off the door and rebuilding it, not dismounting the push bar. Ordering the cam alone is the alternative to replacing the entire 210K trim assembly when only the actuating part has worn.
7) Should I replace just the cam or buy a whole new 210K trim?
If the trim housing, lever, and cylinder prep are sound and only the actuation has gone, the 109872 cam is the targeted fix and keeps the existing finish matched to the rest of your openings. Replace the full 210K trim when the housing is damaged, the finish no longer matches, or the lever has play at the spindle. For a fleet of doors where several trims are failing the same way, stocking the cam is the cheaper maintenance path.
8) Can I keep my existing Von Duprin trim and lock cylinder when installing the 109872?
Yes. The cam is an internal service part for the 210K trim, so the trim plate, lever, and any mortise cylinder already keyed into your system stay in place. Nothing about your keying changes.
