Von Duprin 90029 – Frequently Asked Questions

1) What is the Von Duprin 090029 dog screw and what does it do on an exit device?
The 090029 is the dog screw used on Von Duprin 55 Series exit devices. The dog screw is what holds the push bar depressed so the latch stays retracted and the door pushes open freely, which is how you keep a door on free entry during business hours and then take it back to latching at close. It is a replacement part, so it is what you order when the original screw is stripped, seized, or missing rather than when you need a whole new device.
2) Can I dog a fire rated exit door with this screw?
No. Fire rated exit devices are not permitted to be mechanically dogged, because the device has to latch on every cycle to keep the opening rated. The 090029 carries no fire rating and is intended for non-fire 55 Series openings. On a fire rated door you need electric latch retraction, not a dog screw.
3) What is the difference between the Von Duprin 090029 dog screw and a Falcon 610061 top rod when servicing an exit device?
They replace different things on the device. The Von Duprin 090029 is a 55 Series dog screw, a replacement part sold in packages of 2 with 10 packages per box, and it is the hardware that holds the pushpad in the dogged position. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, which is the rod that drives the top latch. If the pushpad will not stay depressed, the dog screw is the part in question; if the top latch is not throwing, the rod is.
4) Can an Accentra 7110 top latch component be used in place of a Von Duprin 55 Series dog screw?
No. The Accentra 60-7010-0049-999 is a top latch replacement component for the 7110/7120 exit devices, and the Accentra 60-7010-0050-999 is the top latch component for the 7110F. Those are latching parts for Accentra devices. The Von Duprin 090029 is a dog screw for Von Duprin 55 Series exit devices and trim, sold in packages of 2. A device built by one manufacturer takes that manufacturer's service parts, and the two parts do not perform the same function on the device in any case.
5) The exit device on a fire door will not hold open with the pushpad depressed - is a dog screw the right part to order?
Not for a fire-rated opening. The Von Duprin 090029 dog screw is a non-fire-rated commercial part for 55 Series exit devices, and mechanical dogging is not used on fire exit hardware, which must relatch on every cycle. For a fire-rated double door where the problem is the opening rather than the pushpad, the Falcon 4023 steel mullion serves double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are exit device accessories for mullion installations. For a fire-rated single device that is not latching, the failure is in the latch train, not the dogging hardware.
6) How many dog screws come in a package of the Von Duprin 090029?
Two screws per package, and the box holds 10 packages, so a full box is 20 screws. Order quantity runs as either a single package of 2 or a package of 10. For a property manager stocking a building with several 55 Series devices, the box gives you spares on the shelf without reordering each time one strips.
7) Is the Von Duprin 090029 dog screw rated for commercial traffic?
Grade 1, commercial. That is the top commercial rating for door hardware, and it is what a school, hospital, or office building spec normally calls for. The part is built for commercial exit device service, not light residential use.
8) My exit device won't stay dogged. Is the dog screw the part I need?
Usually yes, if the screw itself is chewed up. A dog screw that no longer holds the bar down is normally stripped in the head or worn on the threads, and the 090029 replaces it on a 55 Series device. If the screw is fine and the bar still springs back, the fault is inside the device rather than in the screw, and you are looking at a latch or chassis component instead.
9) Is the Von Duprin 090029 a cylinder part like the Arrow 16RCR-27, or something else?
Something else. The Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin for the 24/25 Series, which is keying hardware that accepts a small format interchangeable core. The Von Duprin 090029 is a dog screw for the 55 Series, a mechanical fastener that sets the pushpad in the held-retracted position, and it has no keyed function. A locksmith rekeying the opening wants the housing; a locksmith restoring dogging wants the dog screw. Similarly, the Falcon 23981160 is a T Series 2-3/8 inch square corner deadlatch replacement part, which is latch hardware rather than dogging hardware.
10) What other exit device replacement parts can I get if the 090029 isn't the piece that failed?
If the problem is the latching end and not the dogging, ZenSupply carries other exit device internals: the Falcon T Series 2-3/8 inch square corner deadlatch replacement part, the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices, and Accentra top latch replacement components for the 7110/7120 and 7110F. Those are different brands and different device families, so match the part to the device you actually have.
11) Do I need any special tools or trim changes to replace a 55 Series dog screw?
No trim change is involved. The dog screw is a service item on the device itself, and swapping it does not touch the outside trim or the door prep. You are replacing a screw in an installed device, which is why keeping a pack on the shelf turns a service call into a few minutes of work rather than a device replacement.
12) For a facility standardizing exit device service parts across several buildings, how does the 090029 pack out compared to single-part replacements?
The Von Duprin 090029 is packaged for stocking rather than one-off repair: it comes in a package of 2 dog screws, with 10 packages per box, and both the package of 2 and the package of 10 are sold. That suits a maintenance shop carrying Von Duprin 55 Series devices across multiple doors. Parts like the Falcon 4023 steel mullion and the Falcon 610061 24 Series concealed vertical top rod are ordered per opening instead, since each is fitted to a specific door and device.
