Von Duprin 50355 – Frequently Asked Questions

1) Does the Von Duprin 050355 cam work on a left hand door?
No. The 050355 is the right hand 55NL cam for the Von Duprin 55 Series. Handing is built into the cam geometry, so a left hand opening needs the left hand version of the part. Determine handing from the outside of the door: if the hinges are on your right as the door swings away from you, it's right hand.
2) What does the 55NL cam actually do in a Von Duprin 55 Series exit device?
It's the internal cam that ties the NL (night latch) outside trim pull to the device mechanism, so turning or pulling the outside trim retracts the latch. If the outside pull has stopped retracting the latch while the push bar still works from inside, a worn or broken cam is the usual culprit. The 050355 is the genuine Von Duprin replacement for that component on the right hand configuration.
3) Can I use the Von Duprin 050355 cam on a fire rated exit device?
No. This 55 Series cam carries a fire rating of No, so it should not be used to service a labeled fire exit device. Fire rated openings require components listed for that assembly; substituting an unlisted part voids the label on the door.
4) I need a latch part for a Falcon exit device, not a Von Duprin. What should I look at instead of the 050355?
For Falcon hardware the 050355 will not apply, since it is a 55 Series Von Duprin cam. Falcon service parts are model-specific: the FAL-23981160 is a 2-3/8 inch square corner deadlatch replacement part for Falcon T Series, and the FAL-610061 is the concealed vertical top rod for Falcon 24 Series Monarch F-25-C and F-25-CWDC exit devices. Identify the Falcon device series first, then pull the matching component.
5) Is this cam suitable for a high traffic commercial opening?
Yes. The 050355 is a Grade 1 commercial component, which is the highest ANSI/BHMA durability tier for door hardware, and it is designated commercial rather than residential. It's the part facility teams use on school, hospital, retail, and office exit devices in the 55 Series.
6) Will this Von Duprin cam fit an Accentra or Falcon exit device?
No. The 050355 is built for the Von Duprin 55 Series only and is not cross-compatible with other brands. If you're servicing another manufacturer's device, match the brand and series: Accentra 7110/7120 and 7110F use their own top latch replacement components, and Falcon T Series uses a Falcon deadlatch part such as the 2-3/8 inch square corner deadlatch.
7) Do I need to replace the whole exit device or can I just swap the cam?
If the device body, push rail, and latch are sound and only the outside NL trim function has failed, the cam alone is the service part. The 050355 is a genuine Von Duprin replacement component, so the device keeps its original function without pulling the unit off the door. Full replacement is only warranted if the chassis or latch itself is damaged.
8) I'm standardizing parts across a building with Von Duprin 55 Series devices. Do I need both handings on the shelf?
Yes, if your openings swing both ways. The 050355 covers right hand doors only, and a mixed set of openings will need the left hand cam stocked alongside it. Walk the building and count handings before you order quantities, rather than assuming one part covers every door.
9) Can an Accentra 7110 top latch component be used in place of the Von Duprin 050355 55NL cam?
No. The Von Duprin 050355 is a 55NL cam handed right and built for the Von Duprin 55 Series exit device line, while the Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices. They are different parts serving different mechanisms in different manufacturers' devices, so neither retrofits the other's chassis.
10) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 050355 cam?
No. The Arrow 16RCR-27 is a 6/7-pin SFIC rim cylinder housing for Arrow 24/25 Series devices, which is the cylinder side of a night latch setup. The Von Duprin 050355 is the 55NL cam itself, the driven component inside a 55 Series device. A locksmith replacing a worn cam needs the 050355; one adding or rekeying an interchangeable core cylinder needs the housing.
11) My problem is a double door opening, not a worn cam. What do I order instead of the 050355?
A cam like the Von Duprin 050355 only addresses the night latch drive inside a single 55 Series device. For a pair of doors needing a fixed point for rim device strikes, 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 mullion installations.
12) What else might I need if I'm working on a pair of doors with 55 Series devices?
The cam only addresses outside trim retraction on one leaf. For a pair of doors secured with rim devices, you also need a mullion between them; ZenSupply carries the Falcon 4023 steel mullion for double door exit device applications, with Falcon 525 aluminum mullion stabilizers available for those installs.
