Von Duprin 51804 SP313 – Frequently Asked Questions

1) What is the Von Duprin 051804 extension rod kit actually for?
It's a 36 inch extension rod kit for the Von Duprin 2227 exit only device in the 22 Series. The 2227 is a surface vertical rod device, and the rod is the part that runs up the door to the top latch. The kit supplies the longer rod length needed when the door is taller than what the standard device ships with. It is the rod hardware only, not a complete exit device, so you still need the 2227 device itself on the door.
2) Will the Von Duprin 2227 extension rod kit work with a 3327 or 9827 device?
No. The 051804 kit is built for the 2227 exit only device in the 22 Series. Von Duprin rods are series specific, so a 33A, 35A, or 98/99 vertical rod device takes its own rod part. Order the extension rod that matches the series stamped on your device.
3) Can I use this Von Duprin extension rod kit on a fire rated door?
No. The 051804 rod kit is not fire rated, and the 2227 it fits is an exit only (non fire) device. Fire rated openings need a fire exit hardware device and its matching fire rated rod set, since fire labeled hardware cannot be dogged and the parts are not interchangeable with the non fire version. If your door has a fire label, this is the wrong part.
4) I have a tall door and my Von Duprin 22 Series vertical rod device won't reach the top. What do I need?
An extension rod. The 051804 gives you 36 inches of additional rod for a 2227, which is what covers openings taller than the standard door height the device is furnished for. Measure from the device centerline to the top latch prep before you order, because the extension is a fixed 36 inch kit rather than a cut to fit length range.
5) Can a Falcon 610061 vertical rod be used in place of the Von Duprin 2227 36 inch extension rod kit?
No. The Von Duprin 051804 is a 36 inch extension rod kit built for Von Duprin 2227 exit only devices in the 22 Series. The Falcon 610061 is a 24 Series Monarch concealed vertical top rod made for F-25-C and F-25-CWDC exit devices, a different manufacturer's device family. Rod kits are matched to the device chassis and its rod guides, so a locksmith replacing rods on a 2227 orders the Von Duprin 22 Series kit, and one working on a Falcon F-25-C orders the 610061. The two are not interchangeable in either direction.
6) Is the Von Duprin 2227 rod kit rated for a high traffic commercial door?
Yes. It's a Grade 1 commercial part, which is the top ANSI/BHMA durability tier for door hardware and the level specified for schools, hospitals, and other high cycle openings. It is not a residential grade accessory.
7) Do I need to re-prep the door to install a Von Duprin 22 Series extension rod?
Not for the rod itself if the device and top latch are already prepped. If you are changing door height or relocating the top strike, Von Duprin publishes 22 Series prep templates for both hollow metal and wood doors, plus separate template indexes for trims and strikes, and those give the exact hole locations. Use the template that matches your door material.
8) I have a pair of doors with no mullion. Is a vertical rod device the right approach, or should I add a mullion?
Both work, and they solve it differently. A surface vertical rod device like the 2227 latches at the head and the threshold, so a pair of doors secures with no center post and the opening stays clear for wide loads. The alternative is a removable mullion with rim devices, which puts a steel post between the leaves and gives you a simpler, cheaper device with fewer moving parts to maintain. If you go the mullion route, ZenSupply carries the Falcon 4023 steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers. Choose the mullion if clear width doesn't matter; stay with vertical rods if it does.
9) My exit device latches at the top but the rod is bent or worn. Do I replace the rod or the whole device?
Replace the rod. On a 22 Series 2227 the vertical rod is a serviceable component, and the 051804 kit supplies rod at 36 inches so you can restore a device that is otherwise sound. Other brands work the same way: ZenSupply stocks the Falcon 610061 concealed vertical top rod for the 24 Series F-25-C and F-25-CWDC devices, and Accentra top latch replacement components for 7110/7120 devices. Match the replacement part to the device series, not just to what the old part looks like.
10) Is the Von Duprin 051804 the same thing as a concealed vertical rod part?
No. The 2227 is a surface applied vertical rod device, so the rod runs on the face of the door where you can see and service it. Concealed vertical rod hardware routes the rod inside the door and takes a different part entirely, such as the Falcon 610061 concealed top rod on that brand's 24 Series. If your rods are hidden inside the door, this kit is not your part.
11) What part fixes a double door opening rather than extending rods on a single exit device?
Extension rods address rod length within one device, so they do not help a pair of doors that needs something to latch against. For that opening the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are a mullion accessory rather than a device part. A contractor with a single exit only door running a Von Duprin 2227 uses the 36 inch extension rod kit; a contractor with a double door pair is solving a mullion problem instead.
12) The top latch on our exit device is worn out, not the rod. What part is that?
A worn top latch is a separate component from the rods that drive it. The Accentra 7110/7120 exit device top latch replacement component and the Accentra 7110F top latch replacement component are the latch itself for those Accentra devices. The Von Duprin 051804 is a 36 inch extension rod kit for Von Duprin 2227 exit only devices, so it addresses rod length on that device rather than replacing a latch. A property manager should identify which piece is failing before ordering, since the two are not substitutes for each other.
13) Does the Von Duprin extension rod kit include the top latch and strike?
The 051804 is the extension rod kit for a 2227, supplied as an installation accessory. The top latch case and the strike are separate items on the device itself. If your top latch is damaged rather than the rod, that's a different part number, and if you're relocating the strike you'll want the 22 Series trims and strikes template for your door material.
14) Can I standardize this rod kit across a building with mixed exit devices?
Only where the openings run Von Duprin 22 Series 2227 devices. The rod is specific to that series and device, so a facility with a mix of manufacturers or 98/99 series hardware needs a different part per device type. If you're standardizing, the practical move is to standardize the devices first at Grade 1 and let the spare parts follow, rather than trying to find one rod that covers everything.
15) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 22 Series extension rod kit?
No, they solve unrelated problems. The Arrow 16RCR-27 is an SFIC rim housing taking a 6 or 7 pin small format interchangeable core, in the Arrow 24/25 Series, so it is a cylinder question for keying an exit device from the outside. The Von Duprin 051804 36 inch extension rod kit is a mechanical part for Von Duprin 2227 exit only devices. A security integrator standardizing keying orders the rim housing; an installer correcting rod length on a 2227 orders the extension rod kit.
16) We need a deadlatch replacement, not a rod kit. What is the difference?
The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part in the Falcon T Series, which is the latching mechanism at the door edge. The Von Duprin 051804 is a 36 inch extension rod kit for Von Duprin 2227 exit only devices in the 22 Series, which sets rod length inside the device. A distributor filling an order should confirm which the job calls for, because the deadlatch and the rod kit belong to different devices and serve different functions.
