Von Duprin 90021 – Frequently Asked Questions

1) Which Von Duprin exit devices does the 090021 crossbar tube attaching ring fit?
The 090021 attaching ring is a genuine Von Duprin replacement part for 55 and 88 Series crossbar exit devices. It secures the crossbar tube to the device assembly, so it applies to those two families only, not to the touchpad-style Von Duprin devices.
2) Can I use the 090021 ring on a fire rated exit device opening?
The 090021 crossbar tube attaching ring is not carried as a fire rated item. If the opening is a labeled fire door, the exit device itself has to be the fire rated model and all replacement components need to match the device manufacturer's listed parts for that label. Use this ring on non-labeled 55 and 88 Series openings.
3) My crossbar is loose at the end cap - is the attaching ring the part I need?
If the loose point is where the crossbar tube meets the device end, the attaching ring is the piece that holds that joint. It is the component that keeps the crossbar tube seated and aligned so the device strokes correctly. A crossbar that is bent or a rod that is out of adjustment is a different repair, and the ring will not correct either.
4) Will a Von Duprin 090021 ring work on a Falcon or Accentra exit device?
No. The 090021 is cut for Von Duprin 55 and 88 Series crossbars and has no cross-brand fit. Other brands use their own service parts: Falcon lists the 610061 concealed vertical top rod for its 24 Series F-25-C devices, and Accentra has top latch components for the 7110/7120. Match the repair part to the device brand on the door.
5) Can an Accentra exit device latch component be used in place of the Von Duprin 090021 attaching ring?
No. The Von Duprin 090021 is a crossbar tube attaching ring for 55 and 88 Series exit devices, sold as a package of 2. 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 top latch component for the 7110F. Those are latching parts for a different manufacturer's devices, not crossbar hardware, so they do not interchange with the 090021.
6) How many attaching rings come in a Von Duprin 090021 order?
Two. The 090021 ships as a package of 2 rings, which covers a crossbar that needs a ring at each end without placing a second order.
7) Is this part rated for a high traffic commercial door?
Yes. The 090021 ring is a Grade 1, commercial-rated component, which is the heaviest duty level used for exit device hardware in schools, hospitals, offices and other high-cycle openings.
8) Do I have to replace the whole exit device to fix a crossbar attachment problem?
No. Von Duprin sells the 090021 attaching ring as an individual OEM service part, so a 55 or 88 Series device can be repaired in place rather than swapped out. That keeps the existing trim, strike and door prep untouched, which matters if you are standardizing a building on one device family.
9) I need a replacement rod for a concealed vertical rod exit device, not a crossbar ring - what should I look at?
The Von Duprin 090021 only addresses crossbar tube attachment on 55 and 88 Series devices. For a concealed vertical rod repair, the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices. It is a rod assembly for Falcon concealed vertical rod devices, so confirm the device family before ordering.
10) What is the difference between the Von Duprin 090021 and a mullion like the Falcon 4023?
They solve different problems. The 090021 is a small crossbar tube attaching ring that keeps the crossbar assembly of a Von Duprin 55 or 88 Series device correctly attached, supplied two per package. The Falcon 4023 is a steel mullion for double door exit device applications - a vertical member installed between a pair of doors to give rim devices a strike surface. A mullion is opening hardware, not a device repair part.
11) Is there a Falcon accessory that does the same stabilizing job as the Von Duprin 090021?
Not an equivalent one. The Falcon 525 is a set of aluminum mullion stabilizers, which steady a mullion in the opening rather than secure a crossbar tube. The Von Duprin 090021 works inside the device itself, holding the crossbar tube on 55 and 88 Series exit devices, and is a Grade 1 commercial-rated part. If the crossbar is loose, the 090021 is the part; if the mullion moves, the 525 addresses that.
12) My exit device problem is a worn latch, not the crossbar - is the Von Duprin 090021 still the right part?
No. The 090021 addresses crossbar tube attachment on Von Duprin 55 and 88 Series devices. For a worn latch on a Falcon T Series device, the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part. Match the repair to the failed component and to the device brand and series on the door.
13) For a fire-rated opening, is the Von Duprin 090021 or one of the comparable exit device parts the fire-labeled choice?
The 090021 carries no fire rating, and the Accentra top latch components 60-7010-0049-999 and 60-7010-0050-999 likewise carry no fire rating. On a labeled opening, verify the complete device assembly against its own fire label rather than selecting a component on the assumption it confers the rating.
14) Does the Von Duprin 090021 have anything to do with cylinder or keying hardware on an exit device?
No. The 090021 is purely a mechanical crossbar tube attaching ring for 55 and 88 Series devices, with no cylinder function. If you are working on the key side, the Arrow 16RCR-27 is an SFIC rim housing for 6 and 7-pin cores in the Arrow 24/25 Series. Those are separate scopes of work on the device.
