Von Duprin 90070 – Frequently Asked Questions

1) Will the Von Duprin 090070 ratchet release screw fit my 99 Series exit device?
The 090070 ratchet release screw is a genuine Von Duprin part for the 33, 35, 98 and 99 Series exit devices, so a 99 Series rim or vertical rod device is covered. If your device is from another Von Duprin family, or another brand entirely, this is not the screw for it.
2) I need a replacement part for an Accentra or Falcon exit device, not Von Duprin. Is the 090070 the right screw?
No. The 090070 is cut for Von Duprin 33/35/98/99 Series hardware only. For Accentra, the 7110/7120 top latch replacement component covers those devices, and the 7110F version covers the 7110F. On the Falcon side, the T Series 2-3/8 inch square corner deadlatch and the 610061 24 Series concealed vertical top rod for F-25-C and F-25-CWDC devices are the Falcon replacement parts we carry. Exit device internals are not interchangeable across brands.
3) A 98 Series device is not latching at the top of the door - is a ratchet release screw the fix or is a vertical rod needed?
Those are two different repairs. The Von Duprin 090070 ratchet release screw is a chassis-level service part for 33/35/98/99 Series devices and comes two per package; it does not address top latching on a concealed vertical rod device. A top rod is a separate component - the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices, which shows the class of part a top-latch problem calls for, but it is a Falcon part for Falcon devices. On a Von Duprin 98, order the Von Duprin rod matched to that device and use the 090070 only for the ratchet release itself.
4) How many screws come in a Von Duprin 090070 package?
Two screws per package. For a single device repair that leaves you a spare on the shelf, which is the usual reason a maintenance shop orders it rather than counting exact pieces, and a two-door job is covered by one package.
5) Can I use the Von Duprin 090070 screw on a fire rated exit device?
The 090070 screw itself carries no fire rating in its own right. Repairs to a fire rated exit device have to keep the device to its listing, so the part to use there is whatever Von Duprin specifies for that fire labeled device. Treat the 090070 as a mechanical replacement screw for the 33/35/98/99 Series, not as a fire rated component.
6) Should I repair my Von Duprin exit device with the 090070 screw or replace the whole device?
If the device body and latching are sound and it is the ratchet release screw that has failed or gone missing, the 090070 puts a genuine Von Duprin screw back in and keeps the rest of the hardware in service. Replacing the whole device only makes sense when the chassis, rail or latch is worn out. Ordering the manufacturer's own part also avoids mixing generic fasteners into a Grade 1 commercial device.
7) The exit device on a fire-rated opening needs a replacement part - is the Von Duprin 090070 or the Accentra 7110F component the right one?
Match the part to the device you actually have on the door, not to the opening's rating. The Von Duprin 090070 ratchet release screw is the service part for Von Duprin 33/35/98/99 Series devices; the Accentra 60-7010-0050-999 is a top latch replacement component for the Accentra 7110F. Neither part is itself fire rated, so on a fire opening the device label and the manufacturer's listing govern - replace like for like with the part built for that device series.
8) Ordering parts for a pair of doors with exit devices - does the Von Duprin 090070 cover the mullion hardware too?
No. The 090070 is a ratchet release screw for Von Duprin 33/35/98/99 Series exit devices, supplied two to a package, and it is a device component only. Mullion hardware for a double-door opening is ordered separately: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 is a set of aluminum mullion stabilizers for exit devices. Put the 090070 on the device service line and the mullion parts on their own line.
9) Is the Von Duprin 090070 a rim cylinder housing or keyed component?
It is neither. The 090070 is a Grade 1 commercial ratchet release screw for Von Duprin 33/35/98/99 Series exit devices, packaged two to a bag, with no keying or cylinder function. A keyed rim component is a separate item - the Arrow 16RCR-27 is an SFIC rim housing for 6/7-pin cores in the Arrow 24/25 Series. If the cylinder side of the device is what needs attention, the 090070 is not the part.
10) Is the Von Duprin 090070 screw heavy duty enough for a high traffic school or hospital door?
It is a Grade 1 commercial part, which is the heaviest duty category in the ANSI/BHMA hardware grading and the level specified for schools, hospitals and other high cycle openings. It is not a residential grade screw.
11) Is the Von Duprin 090070 an aftermarket screw or a factory part?
Factory. The 090070 is sourced from Von Duprin as an authentic replacement component for the 33/35/98/99 Series, which is what matters if you are maintaining a standardized set of exit devices across a building and want every repair to match the original hardware.
12) What is the difference between the Von Duprin 090070 and a Falcon T Series deadlatch replacement part?
They serve different device families and different jobs. The Von Duprin 090070 is a ratchet release screw for Von Duprin 33/35/98/99 Series exit devices, rated Grade 1 for commercial use and sold two per package. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series. Cross-brand replacement parts do not interchange at this level; identify the device series stamped on the hardware and order within it.
