Von Duprin 050183 26D – Frequently Asked Questions

1) What exactly is the Von Duprin 050183 center case kit, and what part of the exit device does it replace?
The 050183 is the center case kit for the Von Duprin 55 Series 55EO rim exit device. The center case is the housing at the middle of the device that carries the internal mechanism the push pad acts on, so this kit lets you rebuild that section instead of pulling and replacing the whole device. It is sold as a replacement part for 55 Series hardware only.
2) What finishes does the Von Duprin 050183 center case kit come in, and do I need to match the rest of my device?
Four finishes: 626 satin chrome, 613 oil rubbed bronze, 605 bright brass and 606 satin brass. The center case is a visible part of the device once installed, so order the finish that matches the existing touch bar and end cap. 626 satin chrome is the common commercial choice.
3) Is there a non-Von Duprin center case that will drop into a 55EO exit device?
No. The 050183 center case kit is built specifically for Von Duprin 55 Series exit devices in the 55EO configuration, and the center case is the internal chassis the rest of the device is built around, so it is series-specific rather than interchangeable. Other exit device internals in the same repair family are matched just as tightly to their own devices: the Accentra 7110/7120 top latch replacement component serves Accentra 7110 and 7120 devices, and the Falcon 610061 top rod is made for Falcon 24 Series Monarch F-25-C and F-25-CWDC concealed vertical rod devices. If the device on the door is a Von Duprin 55, the 050183 kit is the correct part; if it is another maker's device, the repair part has to come from that maker's own parts line.
4) My exit device is failing at the latch, not the push rail - should I still order the 050183 center case kit?
Not necessarily. The 050183 is the center case kit, the chassis at the middle of a Von Duprin 55EO device, so it is the right call when the internal mechanism behind the rail is the problem. If the fault is at the latching point itself, a latch-level part is the closer match: the Accentra 7110/7120 top latch replacement component and the Accentra 7110F top latch component address the top latch on those devices, and the Falcon T Series 2-3/8 inch square corner deadlatch replacement part covers the latch on a Falcon T Series exit device. Diagnose whether the rail travel or the latch throw is failing before you pick, and match the part to the brand of device you actually have.
5) Is this Von Duprin part rated for high traffic commercial use, or is it a light duty replacement?
Grade 1, commercial. That is the heaviest ANSI/BHMA duty class for exit hardware, which is what you want on school corridors, hospital wings, warehouse exits and multi-tenant residential exits. It is not a residential-duty component.
6) My exit device pushes but the latch will not retract. Is the center case the part I need, or something else?
If the pad travels and nothing happens at the latch, the mechanism inside the center case is the usual suspect and the 050183 kit addresses it. If the latch itself is worn or chewed up, or the latchbolt is binding in the strike, that is a latch component rather than the center case. On surface vertical rod devices a rod or a top latch is more often the failure, and those are separate parts, for example the Accentra 7110/7120 top latch on that brand's devices.
7) What does the EO in 55EO mean, and does it change which center case I order?
EO means exit only: no outside trim, no cylinder, no dogging trim on the outside of the door. The 050183 is the center case kit for that 55EO configuration. If your 55 Series device has outside trim or a key cylinder function, confirm the device designation on the unit before ordering, because the internal parts differ from a plain exit-only device.
8) I have a pair of doors with no mullion. Does replacing the center case fix my double door problem?
No, that is a different issue. A center case kit only rebuilds the mechanism on one device. A pair of doors with rim devices and no center mullion needs a mullion to give the latches something to catch, for instance the Falcon 4023 steel mullion for double door exit device applications, with Falcon 525 aluminum mullion stabilizers where stabilizing is required.
9) Should I rebuild the 55 Series device or just replace the whole exit device?
If the pad, rails and latch are sound and the failure is in the middle of the device, the 050183 center case kit restores function for a fraction of the labor of a full swap, and you keep the existing door prep and mounting holes. Replace the whole device instead if the door prep is wrong, the rail is bent, or the opening now needs a fire rated or outside-trim function the 55EO exit-only setup does not provide.
10) Can I use the 050183 center case kit on a fire-rated opening?
The Von Duprin 050183 55 Series center case kit carries a fire rating of No, so it is not the part to specify for a labeled fire door assembly. Several of the neighboring exit device repair parts sit the same way - the Accentra 7110/7120 top latch replacement component and the Accentra 7110F top latch component are both listed with a fire rating of No. For a labeled opening, the replacement component must come from the fire-labeled parts line for that specific device, since substituting an unrated internal part can void the label on the assembly.
11) I have a pair of doors and the device keeps getting knocked out of alignment - is the center case kit what I need?
Probably not. The 050183 center case kit repairs the internal mechanism of a single Von Duprin 55EO device; it does nothing for how a pair of doors meets. For double door openings the part that carries the strike and holds the alignment is a mullion - the Falcon 4023 steel mullion is made for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are an exit device accessory for steadying a mullion. If the device itself is mechanically sound and the problem is the opening, address the mullion first rather than replacing the case.
12) Does the 050183 center case kit include the cylinder housing for keyed access?
No. The 050183 is the center case kit for a Von Duprin 55EO device, and 55EO is an exit-only configuration, so it does not carry keyed cylinder hardware. If you need a keyed rim cylinder housing on an exit device, that is a separate component - the Arrow 16RCR-27 is an SFIC rim housing for 6/7-pin small format interchangeable cores in the Arrow 24/25 Series. Order the cylinder housing appropriate to your device brand alongside the case kit if the opening needs outside key access.
13) Is the Von Duprin 050183 a genuine Von Duprin part or an aftermarket copy?
Genuine Von Duprin, sold as the factory replacement center case kit for the 55 Series. That matters on a device you intend to keep in service: aftermarket center case internals can foul the existing pad and latch geometry.
14) For a high-traffic school corridor, does a repair part like the 050183 hold up the same as the original device?
The Von Duprin 050183 55 Series center case kit is built to Grade 1 and is rated for commercial use, which is the performance tier facilities standardize on for corridor and stairwell traffic. Among the adjacent exit device repair components, the Accentra 7110/7120 and 7110F top latch parts and the Falcon 24 Series 610061 top rod are all device-specific internals in the same way - each restores the original device rather than downgrading it. The practical decision for an institutional buyer is which device families you want to standardize on across the building, since each family carries its own parts list.
