Von Duprin 051807 US28 – Frequently Asked Questions

1) What is the Von Duprin 3327A extension rod kit used for?
The 3327A is a 36 inch extension rod kit for Von Duprin 33 and 35 Series vertical rod exit devices. Vertical rod devices latch at the head and the threshold, so the rods have to span the full door height. When a door is taller than the rod length supplied with the standard device, the extension kit adds the rod length needed to keep the top and bottom latches engaging correctly. It is a rod component only, not a complete exit device.
2) Will the Von Duprin 3327A rod kit work on a 99 or 98 Series exit device?
No. The 3327A extension rod kit is built for the Von Duprin 33 and 35 Series platform only. Rod kits are cut and threaded to a specific device family, so a kit from one series will not carry over to another. If you are servicing a device from a different Von Duprin family, order the extension rod kit that matches that family.
3) Can I use the Von Duprin 3327A extension rod kit on a fire rated door?
No. The 3327A rod kit is not fire rated, so it should not be used to service a fire labeled opening. Fire rated exit device assemblies have to be built from labeled components end to end, and substituting a non-rated rod kit breaks the label. For a fire opening, use the fire rated rod kit that matches the fire rated version of your device.
4) What is the equivalent vertical rod part if the exit device is a Falcon 24 Series Monarch instead of a Von Duprin 33 or 35 Series?
The Von Duprin 3327A extension rod kit is built for the Von Duprin 33/35 Series platform and does not carry over to a Falcon device. For a Falcon 24 Series Monarch concealed vertical rod device, the corresponding rod is the Falcon 610061 concealed vertical top rod, which is specified for F-25-C and F-25-CWDC exit devices. Match the rod to the device family it was made for -- vertical rod lengths, connections, and latch engagement are platform-specific, so a locksmith servicing a mixed building should order by device series rather than by rod length alone.
5) Is a mullion an alternative to an extension rod kit on a tall door pair?
No -- they solve different problems. The Von Duprin 3327A extension rod kit supplies rod components so a 33 or 35 Series vertical rod device reaches the top and bottom latch points on a taller door. A mullion such as the Falcon 4023 steel mullion is a removable center post for double door exit device applications, giving a rim device something to latch into on a pair with no fixed astragal. If the door is tall and the device is vertical rod, the rod kit is the part; if the opening is a pair being converted to rim devices, the mullion is the part.
6) Can an extension rod kit be used on a fire rated opening?
The Von Duprin 3327A extension rod kit carries a fire rating of No, as do the Accentra 7110/7120 and 7110F top latch replacement components. On a labeled opening, the whole assembly has to be a listed fire exit hardware configuration, so specify parts carried as fire rated rather than adapting a non-rated accessory. For a non-labeled commercial opening -- an office corridor, a retail exterior pair, a warehouse egress door -- the 3327A is a Grade 1 commercial accessory for the 33/35 Series.
7) My double doors have no mullion and one leaf keeps sagging out of latch at the top. Is an extension rod kit the fix?
Only if the rod length itself is wrong for the door height. The 3327A kit adds rod length for taller 33 or 35 Series vertical rod applications. If your rods are the correct length and the top latch still misses, the problem is usually rod adjustment, a worn top latch, or the strike position at the head, not rod length. Measure your door height and confirm the existing rods are short before ordering an extension kit.
8) I have a pair of doors with no mullion. Should I use vertical rod devices or add a mullion with rim devices?
Vertical rod devices latch into the head and the threshold, so both leaves swing free with no center post in the opening, which is what you want when you need to move wide loads through. The tradeoff is more parts on the door and more adjustment over time, and taller doors need longer rods such as the 33/35 Series 36 inch extension kit. A removable mullion with rim devices is the simpler mechanical answer: fewer moving parts, but a post in the middle of the opening. Falcon offers a steel mullion (4023) for double door exit device applications if you go that route.
9) Is there a concealed vertical rod replacement rod available from another brand?
The Von Duprin 3327A is a surface rod kit for 33 and 35 Series devices. If your device is a concealed vertical rod unit, the rods live inside the door and are not interchangeable with surface rod parts. Falcon carries a concealed vertical top rod, part 610061, for its 24 Series Monarch F-25-C and F-25-CWDC devices. Match the rod to the exact device family in your door, concealed to concealed and surface to surface.
10) My top latch is worn out. Does the Von Duprin 3327A kit include a latch?
The 3327A is a rod kit, supplying the 36 inch rod components for 33 and 35 Series vertical rod devices. A failed top latch is a separate part. On other brands the top latch is ordered as its own replacement component, for example Accentra sells top latch replacement components for its 7110/7120 and 7110F devices. Diagnose which part failed before ordering, since a new rod will not cure a worn latch.
11) What should I order if the exit device latches fine but the top latch itself is worn?
An extension rod kit will not help a failed latch. The Von Duprin 3327A kit addresses rod travel on 33 and 35 Series vertical rod devices. If the latch mechanism at the head of the door is the worn item on an Accentra device, the top latch replacement components are the Accentra 60-7010-0049-999 for 7110/7120 devices and the Accentra 60-7010-0050-999 for the 7110F. Diagnose whether the rod is short or misadjusted versus the latch bolt being worn before ordering, because the two failures look similar from the floor.
12) The vertical rod device rattles at the top of the door -- do I need longer rods or something else?
Rattle and short throw are different symptoms. The Von Duprin 3327A extension rod kit is the answer when rod length has to reach a taller door for correct vertical rod travel and latching on a 33 or 35 Series device. Play or flex at a removable mullion on a pair is a different fix: Falcon 525 aluminum mullion stabilizers are made for steadying mullions in exit device applications. Confirm whether the movement is in the rod or in the center post before ordering either.
13) Will an exit device cylinder housing or a deadlatch part substitute for a rod kit?
No. The Von Duprin 3327A is an installation accessory that supplies rod components for 33 and 35 Series vertical rod devices. An Arrow 16RCR-27 SFIC rim housing is the small format interchangeable core housing, 6/7-pin, on the 24/25 Series -- it is about keying the device, not latching the door. A Falcon 23981160 2-3/8 inch square corner deadlatch is a T Series replacement latch. Distributors cross-referencing an exit device order should keep these three families separate: rods carry motion to the latch points, housings carry the core, deadlatches are the latching hardware itself.
14) Is the Von Duprin 3327A rod kit rated for high traffic commercial use?
Grade 1, which is the heavy duty commercial classification and the level specified for schools, hospitals, and other high traffic openings. It is designated commercial rather than residential, so it is the right grade for a facility standardizing on Grade 1 exit hardware across a building.
