Von Duprin 90027 – Frequently Asked Questions

1) Will the Von Duprin 090027 guide screw fit exit devices other than the 55 Series?
No. The 090027 lift member guide screw is a Von Duprin part made for the 55 Series exit device line only. If you're servicing a 98/99, 33A/35A or any other Von Duprin family, the guide screw for that device is a different part number. Confirm the series stamped on the device chassis before ordering.
2) I have a pair of doors with exit devices and no center post - what do I order instead of the 090027?
The Von Duprin 090027 is an internal guide screw for a single 55 Series device and does nothing for a double-door opening. For a pair of doors needing a removable center post, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers address mullion movement on those openings. Order the mullion hardware for the opening and keep the 090027 as device-level service stock.
3) How many screws come in a pack of Von Duprin 090027?
Ten screws per package. That quantity suits a maintenance crib or a service van more than a single repair, so if you only have one lift member to fix you'll have nine spares on the shelf for the next call.
4) What does the lift member guide screw actually do in a 55 Series exit device?
It's the fastener that keeps the lift member located inside the device so the push rail travels the way it should and retracts the latch. When it works loose or strips, the touchbar can feel sloppy or fail to pull the latch fully. Replacing it is routine maintenance rather than a rebuild.
5) Is the Von Duprin 090027 screw suitable for a fire rated exit device opening?
The 090027 carries no fire rating of its own. It is a Grade 1 commercial part for the 55 Series. On a labeled fire door assembly, the rating rests on the device and the listed assembly, so match parts to what the device label calls for.
6) I need a different exit device internal part, not a guide screw. What else is out there?
Depends on the brand and the component. For latch work, ZenSupply carries the Accentra 7110/7120 top latch replacement and the Falcon T Series 2-3/8 inch square corner deadlatch. For concealed vertical rod devices there's the Falcon 610061 24 Series Monarch top rod for F-25-C and F-25-CWDC. None of those interchange with a Von Duprin 55 Series, so match the part to the device brand and series on the door.
7) Can an Accentra 7110 latch part be used in place of the Von Duprin 090027 guide screw?
No. The Von Duprin 090027 is a lift member guide screw for the Von Duprin 55 Series exit device, sold 10 screws to a package. The Accentra 60-7010-0049-999 is a top latch replacement component for the Accentra 7110/7120 exit devices, and the 60-7010-0050-999 is the top latch component for the fire-rated 7110F. Those are latch assemblies for a different manufacturer's chassis, not fasteners, so they neither fit the 55 Series nor perform the same job.
8) My 55 Series exit device is on a fire-rated opening - is the 090027 the right part?
The Von Duprin 090027 guide screw itself carries no fire rating, so it should not be used to maintain the listed condition of a fire door assembly. For fire-rated exit device work, parts are called out against the fire-rated device, the way the Accentra 60-7010-0050-999 top latch is specified for the 7110F fire device rather than the standard 7110/7120 part. Confirm the device model on the door before ordering replacement components for a labeled opening.
9) What is the difference between ordering the 090027 and ordering a full latch or rod assembly?
The Von Duprin 090027 is a small fastener - the lift member guide screw - supplied in packs of 10 for routine 55 Series service. Replacing worn latching hardware is a different order entirely: a Falcon 23981160 is a 2-3/8 inch square corner deadlatch for the T Series, and a Falcon 610061 is the concealed vertical top rod for 24 Series Monarch F-25-C and F-25-CWDC devices. Use the 090027 when the guide screw is stripped or missing; use a latch or rod part when the latching mechanism itself has failed.
10) Is this a genuine Von Duprin part or an aftermarket screw?
Genuine Von Duprin, catalogued as a replacement component for the 55 Series. Using the factory screw matters here because the guide screw head and shank geometry set how the lift member rides; a hardware-store substitute of the same thread can still bind the mechanism.
11) Is the 090027 a residential or commercial exit device part?
Commercial. Von Duprin builds the 55 Series for commercial openings, and this screw is rated Grade 1 alongside it, which is the heaviest-duty ANSI/BHMA tier for door hardware. Typical homes are schools, offices, healthcare, retail and multi-tenant buildings.
12) Can I buy just one 090027 screw instead of the ten-pack?
The 090027 is supplied as a package of ten; that is how the part is packaged from the factory. Order the pack and keep the balance as service stock for the other 55 Series devices in the building.
13) Is the 090027 related to the cylinder or keying side of an exit device?
No. The Von Duprin 090027 is a mechanical fastener inside the 55 Series device, rated Grade 1 for commercial use. Keying components are a separate line: the Arrow 16RCR-27 is a 6/7-pin SFIC rim housing for the 24/25 Series. If the complaint is about the key or cylinder rather than device operation, the rim housing family is where to look, not the guide screw.
