Von Duprin 50354 – Frequently Asked Questions

1) Will the Von Duprin 050354 latch bolt spring work on a 99 or 33A exit device?
No. The 050354 rim latch bolt spring is built for the Von Duprin 55 Series rim exit device line only. It is a service part matched to that family's latch assembly, so ordering it for a 98/99 or 33/35 device gets you a spring that does not belong in the mechanism. Confirm the device you are servicing is stamped 55 Series before you order.
2) Can I use the Von Duprin 050354 spring on a fire rated exit door?
The 050354 spring is not carried as a fire rated component. On a labeled opening the whole exit device assembly has to remain as listed, so use the fire rated service part specified for that device rather than this one. For non-labeled commercial openings running 55 Series rim hardware, it is the correct spring.
3) My 55 Series push bar latches sluggishly and the bolt hangs out - is a spring the fix?
A latch bolt that does not snap back or return fully is the classic worn-spring symptom, and the 050354 is the rim latch bolt spring for the 55 Series device. Replacing it restores the bolt's return force. If the bolt is chewed, bent, or the strike alignment has shifted, the spring alone will not solve it - that is a latch or strike problem, not a spring problem.
4) Will an Accentra 7110/7120 top latch replacement component work in place of the Von Duprin 050354 rim latch bolt spring?
No. The Von Duprin 050354 is a rim latch bolt spring built to the 55 Series exit device line, and it restores spring action inside that latch. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, and the 60-7010-0050-999 is the same style of top latch component for the 7110F. Those are latch assemblies for a different manufacturer's device family, so a 55 Series rim latch that has lost spring tension takes the 050354, not an Accentra top latch part.
5) The latch on my exit device is worn out, not just weak. Is there a full latch part instead of a spring?
The Von Duprin 050354 replaces only the rim latch bolt spring inside a 55 Series device, so it addresses a latch that has gone soft or sluggish rather than one that is chewed up. When the latch body itself is the problem, the equivalent repair is a complete latch part rather than a spring: the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the T Series, and the Accentra 60-7010-0049-999 is a top latch replacement component for 7110/7120 devices. Match the repair part to the device brand and series already on the door.
6) My exit device runs rods to the top of the door rather than latching into the frame. Do I still order the 050354?
No. The Von Duprin 050354 is a rim latch bolt spring, which means it serves a rim device that latches into a strike on the frame or mullion. A device that throws a rod to the head of the frame is a vertical rod device and repairs at the rod: the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices. Identify whether the device latches at the rim or through rods before ordering the repair part.
7) Is the Von Duprin 050354 a genuine Von Duprin part or aftermarket?
Genuine Von Duprin, built to the original 55 Series specification and carried as a manufacturer replacement part. That matters on service work where a facility standardizes on Von Duprin hardware and an aftermarket spring rate can change how the bolt behaves.
8) Is the 55 Series exit device spring rated for heavy commercial traffic like a school or hospital corridor?
Grade 1, the commercial duty level, which is what you want on high-cycle openings in schools, hospitals, offices and municipal buildings. Grade 1 is the top ANSI/BHMA duty tier for door hardware, so the spring is matched to the cycle demands of the device it goes into rather than to a light-duty application.
9) What other exit device latch service parts can I get if mine is not a Von Duprin 55?
Depends on the device on the door. For Accentra 7110/7120 devices there is a top latch replacement component, and a separate one for the 7110F. Falcon T Series openings take the 23981160 2-3/8 inch square corner deadlatch. Falcon 24 Series concealed vertical rod devices (F-25-C and F-25-CWDC) use the 610061 top rod. Match the part to the device family stamped on your hardware - exit device internals do not cross between manufacturers.
10) Is the Arrow 16RCR-27 rim housing a substitute for a Von Duprin rim exit device part like the 050354?
They share the word rim but do different jobs. The Von Duprin 050354 is a rim latch bolt spring that restores latch bolt action in a 55 Series exit device. The Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin configuration for the 24/25 Series, which is the cylinder housing that accepts a small format interchangeable core for keyed access. If the complaint is that the latch does not spring back, that is the 050354; if the complaint is about the key cylinder, it is a housing and core question.
11) The rim device on a pair of doors will not latch. Is a latch spring the right fix?
Check the mullion before the spring. A rim exit device on a pair latches into a mullion, so a loose or missing mullion produces a device that will not catch even when the latch is healthy. The Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are exit device accessories that steady a mullion in place. If the mullion and strike are sound and the latch bolt simply does not return, that points back to the Von Duprin 050354 rim latch bolt spring on a 55 Series device.
12) Does replacing the latch bolt spring on a rim exit device require taking the door down?
No. The 050354 serves the rim latch on a 55 Series device, and rim devices mount on the face of the door with the latch at the strike jamb, so the work is done with the door hung. Nothing in the frame head or threshold is involved, unlike a vertical rod device where servicing means getting at rods top and bottom.
