Von Duprin 50353 – Frequently Asked Questions

1) Will the Von Duprin 050353 axle fit any Von Duprin exit device, or only the 55 Series?
The 050353 rim latch bolt axle is built for the Von Duprin 55 Series rim exit devices only. It is a series-specific internal pin for the latch bolt, so pulling it into a 22, 33A/35A or 98/99 device is not a fit called out anywhere in the part's data. If the device on your door is not a 55 Series rim device, order the axle that matches that series instead.
2) My 55 Series exit device latch bolt is sloppy and won't retract cleanly. Is the axle the part I need?
That's the symptom this part addresses. The axle is the pivot the rim latch bolt turns on, and when it wears the bolt starts to bind, drag, or fail to retract fully. Replacing the axle restores proper latch bolt travel without swapping the whole device. If the bolt itself is chewed up or the deadlatch face is worn, you'll want the latch assembly too, not just the axle.
3) Can an Accentra 7110/7120 top latch component be used in place of the Von Duprin 050353 55 Series rim latch bolt axle?
No. The Von Duprin 050353 is a rim latch bolt axle built for Von Duprin 55 Series rim exit devices, so it only goes into that series' latch assembly. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, which is a different manufacturer's device and a different part of the device - a top latch rather than a rim latch bolt axle. Neither part crosses over; match the replacement part to the brand and series of the device already on the door.
4) I need a latch part for a Falcon exit device, not Von Duprin - what should I be looking at?
The Von Duprin 050353 rim latch bolt axle serves Von Duprin 55 Series rim exit devices and will not service a Falcon device. For Falcon, the deadlatch replacement part is the FAL-23981160, a T Series 2-3/8 inch square corner deadlatch. For concealed vertical rod devices, Falcon lists the 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices. Identify the Falcon series stamped on the device before ordering.
5) Is the 050353 rated for a high traffic commercial opening like a school corridor?
Yes. The axle is a Grade 1, commercial-rated component, which is the top durability tier for door hardware and what you want behind a school, hospital or office corridor door that cycles all day. It is not a residential-grade part.
6) Is there an equivalent latch replacement part if my exit device is not a Von Duprin?
Other brands publish their own latch service parts, and they are not interchangeable with the Von Duprin 050353. On Accentra 7110/7120 devices the top latch replacement component is the part to call out (with a separate version for the fire-rated 7110F). On Falcon T Series, the 2-3/8 inch square corner deadlatch is the replacement latch. Match the part to the device brand and series that's on the door.
7) My 55 Series device is on a pair of doors with no center post - is the 050353 the part I need?
Only if the fault is in the rim latch bolt itself. The Von Duprin 050353 is a rim latch bolt axle, an internal latch component. What a pair of doors without a center post needs to give a rim device something to latch into is a mullion: Falcon lists the 4023 steel mullion for double door exit device applications, along with the 525 aluminum mullion stabilizers for exit devices. Those address the opening; the 050353 addresses a worn axle in the device.
8) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 050353?
No - they do different jobs. The Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin configuration for Arrow 24/25 Series devices, and it is the cylinder side of the hardware, the part that accepts a small format interchangeable core. The Von Duprin 050353 is a rim latch bolt axle inside a Von Duprin 55 Series rim exit device's latch mechanism. Order the Arrow housing if you are keying or rekeying the device, the 050353 if the latch bolt no longer throws or retracts properly.
9) Is the Von Duprin 050353 suitable for a fire-rated opening?
The Von Duprin 050353 55 Series rim latch bolt axle is a Grade 1 commercial component and is carried as non-fire-rated, the same way the Accentra 7110F top latch component (60-7010-0050-999) is carried. For openings with a labeled door assembly, confirm the full device model and its label listing before substituting any internal latch component.
10) Is this a genuine Von Duprin part or an aftermarket copy?
It's a genuine Von Duprin service part, catalogued by Von Duprin as a replacement component for their own 55 Series devices. That matters on a rim device because the axle is a press-fit pin at a fixed diameter and length, and an off-size aftermarket pin either wallows the hole or won't seat.
11) Do I need a locksmith to install the 050353 axle, or can maintenance staff do it?
It is meant for someone who has had a Von Duprin rim device apart before. Getting to the axle means pulling the end case and the latch assembly, and the bolt has to go back on the pivot in the right orientation to retract properly. A maintenance tech who services exit devices regularly can handle it; otherwise put a locksmith on it, because a mis-seated latch on an egress door is a life-safety problem.
