Von Duprin 90028 – Frequently Asked Questions

1) What is the Von Duprin 090028 spring and what part of the exit device does it go in?
The 090028 is the end case spring for Von Duprin 55 Series exit devices, sold four to a package. It is a genuine Von Duprin service part, so it is intended for 55 Series devices already hung on the door rather than as a universal spring. If your device is a different Von Duprin family, this is not the spring for it.
2) Will the Von Duprin 090028 end case spring work on a fire rated exit device?
No fire rating is carried on the 090028 end case spring, so treat it as a non-fire-rated part and do not use it to service a labeled fire exit device. On a fire rated opening the whole assembly has to stay as listed, which means a fire-rated service part for that specific device. For non-labeled 55 Series exits, the 090028 is the correct end case spring.
3) Why does an exit device push bar feel dead or fail to return, and is a spring the fix?
When a 55 Series push bar goes soft, stays depressed, or does not spring back cleanly after each push, a fatigued end case spring is the usual culprit. The 090028 restores that return action inside the end case. If instead the latch is not throwing or the rod is not retracting, the problem is in the latch or rod assembly and a spring will not correct it.
4) I have an Accentra or Falcon exit device, not a Von Duprin. Will this spring fit?
No. The 090028 is built for the Von Duprin 55 Series and exit device internals are not cross-brand. For an Accentra 7110 or 7120, the top latch replacement component for that family is the part to look at, and Accentra also lists a separate top latch component for the 7110F. Falcon devices take Falcon parts, such as the T Series 2-3/8 inch square corner deadlatch. Match the service part to the device brand and series stamped on the case.
5) Is the Falcon 610061 top rod an alternative to the Von Duprin 090028 end case spring?
No. The Von Duprin 090028 is an end case spring for 55 Series exit devices, sold four to a package. The Falcon 610061 is a concealed vertical top rod for the 24 Series Monarch F-25-C and F-25-CWDC exit devices. A rod carries the latching motion the length of the door; the end case spring works inside the device end case. They are different components on different device families and neither substitutes for the other.
6) My double doors need exit hardware parts - is the Von Duprin 090028 what I want, or a mullion?
Different jobs. The 090028 is an internal end case spring that restores the action of an existing Von Duprin 55 Series exit device. For a pair of doors, the removable center post is the mullion: the Falcon 4023 is a steel mullion for double door exit device applications, and Falcon 525 aluminum mullion stabilizers are exit device accessories that steady the mullion in place. If the device itself is working and only the pair needs a strike point, the mullion is the part; if the device is sluggish or not resetting, the spring is.
7) My exit device sags at the head on a pair of doors. Will replacing the end case spring fix it?
No, that is a different problem. An end case spring like the 090028 governs push bar return inside the device case, not the security of a pair of doors. Pairs without a center mullion depend on either a vertical rod device or a removable mullion, and if the issue is a rim device pair losing its center point the fix is mullion hardware, such as the Falcon 4023 steel mullion, with Falcon 525 aluminum mullion stabilizers where the mullion needs steadying. If a concealed vertical rod is the real problem, that is a rod replacement, for example the Falcon 610061 top rod for F-25-C and F-25-CWDC devices.
8) What model number do I order for the Von Duprin 55 Series end case spring?
Order Von Duprin 090028. That is the full designation for the 55 Series end case spring, and there is one configuration, so there is no finish, handing, or length to specify. Quantity comes fixed at four springs per package.
9) The 090028 spring is not fire rated - what does that mean when I compare it to other exit device parts?
The Von Duprin 090028 55 Series end case spring carries no fire rating, and the same is true of the Accentra 7110/7120 top latch component 60-7010-0049-999 and the Accentra 7110F top latch component 60-7010-0050-999. On a labeled opening the rating belongs to the door, frame and complete listed device assembly rather than to an individual internal service part, so match the replacement to the device family it was built for and keep the device assembly intact.
10) Is a deadlatch part like the Falcon 23981160 the same kind of repair as the Von Duprin 090028?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the T Series, which is the latching component that engages the strike. The Von Duprin 090028 is an end case spring for the 55 Series, a package of four springs that go inside the device end case. A worn latch and a tired spring produce different symptoms, so identify whether the device fails to latch or fails to return before ordering.
11) Can I order the Arrow 16RCR-27 rim housing instead of the Von Duprin 090028 for my 55 Series device?
No. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing for the Arrow 24/25 Series, which is the cylinder side of the hardware and is what you order when the keying changes. The Von Duprin 090028 is a Grade 1 commercial end case spring for 55 Series exit devices and does nothing for keying. A rekey and a mechanical rebuild are separate orders.
12) For standardizing exit device spares across a facility, how do I decide between stocking the Von Duprin 090028 and the Accentra top latch components?
Stock by the device families actually hanging in the building. The Von Duprin 090028 covers 55 Series devices and comes four springs to a package, which suits a multi-door site from a single order. The Accentra 60-7010-0049-999 covers 7110 and 7120 devices and the 60-7010-0050-999 covers the 7110F. Buildings that were fitted out in phases often carry more than one family, so walk the openings and record the series before setting the spares list.
13) Is four springs the right quantity for a single door repair?
The 090028 comes only as a package of four, which suits a maintenance shop servicing several openings rather than a one-door repair. Property managers and MRO buyers with a run of 55 Series doors usually rebuild several devices in one pass, so the pack covers multiple units with spares left on the shelf.
