Von Duprin 50366 – Frequently Asked Questions

1) Will the 050366 spring lever fit a Von Duprin exit device from another series, like a 98/99 or 33A?
No. The 050366 is built for the Von Duprin 55 Series end case and nothing else. Von Duprin end case internals are series specific, so pull the model number stamped on your device before ordering. If the device is not a 55 Series, this lever is the wrong part.
2) Can I use the Von Duprin 050366 on a fire rated opening?
Not as a fire rated component. The 050366 carries no fire rating. On a labeled fire door assembly, every part of the exit device has to remain within the listing, so repairs there should be made with fire rated hardware. Use this lever on non-rated openings.
3) My 55 Series push bar feels loose or does not spring back. Is the end case spring lever the part I need?
That is the symptom this part addresses. The 050366 restores spring-loaded lever action inside the end case, so a bar that stays depressed, returns slowly, or feels slack at the end case is the case for replacing it. If the latch itself is not retracting or the rods are out of adjustment, the fault is elsewhere in the device and a different service part applies.
4) Can an Accentra 7110 top latch component be used in place of the Von Duprin 050366 end case spring lever?
No. The Von Duprin 050366 is an end case spring lever for Von Duprin 55 Series exit devices, and it is made to restore spring-loaded lever action inside the end case assembly. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices - a different part of the device, on a different manufacturer's chassis. Neither part crosses over; order the 050366 for a 55 Series end case and the Accentra part only for Accentra 7110/7120 hardware.
5) We standardize repair parts across a portfolio - does the Von Duprin 050366 cover exit devices from other manufacturers on our doors?
It does not. The 050366 is a Grade 1 commercial replacement part built for Von Duprin 55 Series exit devices specifically. Openings running other brands need brand-matched components: Accentra 7110/7120 devices take the 60-7010-0049-999 top latch component, Falcon T Series takes the 23981160 deadlatch part, and Falcon 24 Series Monarch concealed vertical rod devices take the 610061 top rod. Inventory by device series rather than by one universal spare.
6) Is this Von Duprin end case spring lever heavy duty enough for a school or hospital entrance?
It is a Grade 1 commercial part, which is the heavy duty tier for door hardware and the right level for high traffic openings in schools, hospitals, offices, retail and government buildings. The device it goes into should already be a 55 Series unit rated for that duty.
7) What other exit device repair parts are available if the 050366 is not the failure on my device?
Depends on the brand and the failure point. For latching problems rather than push bar spring problems, ZenSupply carries the Accentra 7110/7120 exit device top latch and the 7110F top latch, the Falcon 610061 concealed vertical top rod for 24 Series Monarch F-25-C and F-25-CWDC devices, and the Falcon T Series 2-3/8 inch square corner deadlatch. None of those interchange with a Von Duprin 55 Series end case; they are the equivalent service parts on their own brands.
8) I have a pair of doors and want to keep the exit devices working without replacing them. Is a spring lever what I need, or a mullion?
Two different jobs. The 050366 spring lever repairs the end case on a single 55 Series device. If your issue is securing a pair of doors rather than a worn device, that is a mullion question, and ZenSupply carries the Falcon 4023 steel mullion for double door exit device applications along with Falcon 525 aluminum mullion stabilizers.
9) If I am repairing a concealed vertical rod device rather than a 55 Series end case, is there an equivalent to the Von Duprin 050366?
No - the 050366 is an end case component and has no role in a vertical rod assembly. For concealed vertical rod repairs on Falcon 24 Series Monarch F-25-C and F-25-CWDC devices, the Falcon 610061 is the concealed vertical top rod replacement. Rods and end case springs are separate wear items, so confirm which one is actually failing before ordering.
10) I have a pair of doors with a mullion - do I need the Von Duprin 050366 or a mullion part?
Those solve different problems. The 050366 is an internal spring lever for a Von Duprin 55 Series exit device end case. For double door openings that need the vertical post between leaves, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers support mullion installations. Order the mullion hardware for the opening layout and the 050366 only when the device's end case lever spring needs restoring.
11) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 050366?
No. The Arrow 16RCR-27 is an SFIC rim housing for 6/7-pin cores in the Arrow 24/25 Series - a cylinder component that carries the keyed control of the device. The Von Duprin 050366 is a mechanical spring lever inside the 55 Series end case and has nothing to do with keying or cylinder prep. A locksmith rekeying a device wants the rim housing; a technician chasing a sluggish lever return wants the 050366.
12) Where do I find the Von Duprin 55 Series specs to confirm this part is what my device uses?
Von Duprin publishes a 55 Series catalog, and ZenSupply carries it with the part so you can match the end case assembly before you order. Check it against the model stamped on your device and the exploded view of the end case.
13) Is the Von Duprin 050366 a genuine factory part or an aftermarket copy?
Genuine Von Duprin. It is sourced as an authentic replacement component for the 55 Series, which matters on a facility where the devices are standardized and you want fit and finish to stay consistent across openings.
