Von Duprin 50401 – Frequently Asked Questions

1) Does the Von Duprin 050401 bottom latch kit come with the latch cover?
No cover is included. The 050401 is the less-cover configuration, so you get the bottom latch assembly only. If the original cover on your device is damaged or missing, you have to source that separately; if the existing cover is intact, reuse it and this kit drops in underneath it.
2) Can I use a Von Duprin 050401 bottom latch kit on a fire rated door?
Not as a fire rated assembly. The 050401 bottom latch kit carries no fire rating, so it belongs on non-rated openings. On a labeled fire door, servicing an exit device with an unrated component can void the label, and fire rated vertical rod devices are normally supplied less bottom rod anyway. Check the label on your opening before you order.
3) My bottom latch will not hold the door at the threshold. Do I need a whole new exit device?
Usually not. On a 2227, 33/3527, 98/9927 or 98/9957, the bottom latch is a serviceable assembly, and the 050401 kit replaces it without touching the touchbar, the rods, or the top latch. That keeps the existing door prep and the existing trim in place, which is the cheap way out of a failed bottom latch on a high-traffic commercial opening.
4) Is there a top latch replacement equivalent to the Von Duprin 050401 bottom latch kit?
The Von Duprin 050401 is a bottom latch kit supplied less cover for 2227, 33/3527, 98/9927 and 98/9957 exit devices, so it restores the latch at the bottom of the opening only. When the failed latch is at the head of the door instead, the Accentra 7110/7120 Exit Device Top Latch Replacement Component covers that position on Accentra 7110 and 7120 devices. The two parts sit at opposite ends of a vertical rod device and are not interchangeable with each other.
5) My concealed vertical rod device needs a rod, not a latch. What part replaces that?
The Von Duprin 050401 is a bottom latch kit and does not include vertical rod. For a concealed vertical rod assembly where the rod itself is the failed component, the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices. A latch kit and a rod address different failures in the same device, so confirm which one is worn before ordering.
6) Is the 050401 an original Von Duprin part or an aftermarket bottom latch?
It is a genuine Von Duprin replacement part, not a generic aftermarket copy. For a locksmith or an institutional maintenance shop that keeps devices matched across a building, that matters: the kit is built to the same Grade 1 commercial standard as the devices it services, so the bottom latch geometry matches what came out of the device.
7) I need a top latch, not a bottom latch. Is the 050401 the right kit?
No. The 050401 covers the bottom latch at the threshold only. If the failure is at the head of the door you need the top latch component for your device, and for Accentra 7110/7120 devices ZenSupply carries the Accentra top latch replacement component, with a separate version for the fire rated 7110F. Confirm which end of the door is not latching before ordering.
8) Is the Von Duprin 050401 bottom latch kit strong enough for a school or hospital entrance?
Grade 1, which is the heaviest commercial duty class and what a school, hospital, office tower or municipal building is normally specified to. It is a commercial-only part, so it is not intended for light residential duty. On high-cycle egress doors, the bottom latch is one of the first things to wear, and replacing it in kind keeps the opening at its original duty rating.
9) I am standardizing exit device parts across a building with a pair of doors and no mullion. Does one 050401 do both leaves?
One kit services one bottom latch, so a pair of vertical rod doors with a latch at each threshold needs two. That is the trade off with vertical rod devices: they secure a pair with no center mullion, but every leaf carries its own top and bottom latch to maintain. If you would rather remove the vertical rods and go to rim devices on a pair, a removable mullion such as the Falcon 4023 steel mullion is the other way to secure that opening.
10) What is the difference between the Accentra 7110/7120 and 7110F top latch replacement components?
Both are top latch replacement components for Accentra exit devices. The 60-7010-0049-999 part is built for the 7110 and 7120 devices, while the 60-7010-0050-999 part is specific to the 7110F device. Match the part to the exact device model stamped on the chassis, since the two are catalogued separately rather than as one part covering both.
11) Can a Falcon T Series deadlatch part be used in place of the Von Duprin 050401?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for T Series hardware, which is a latch body for a bored lock prep rather than a component of a panic device. The Von Duprin 050401 is a bottom latch kit for 22/33/98 Series exit devices. They serve different door preps and neither retrofits the other.
12) The bottom latch on a pair of doors will not hold. Is a mullion the fix instead of a latch kit?
They solve different problems. The Von Duprin 050401 restores bottom latch function inside a 2227, 33/3527, 98/9927 or 98/9957 exit device. A mullion is a separate vertical member between two leaves that gives a rim device something to latch into. The Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers steady a mullion in service. If the device's own bottom latch is worn, the latch kit is the part; if the opening has no strike point between leaves, that is the mullion's job.
13) Does the Von Duprin 050401 include a cylinder or keyed housing?
No. The 050401 is a bottom latch kit supplied less cover, so it carries no keying hardware. Keyed cylinder work on a rim device is handled by a separate housing such as the Arrow 16RCR-27 SFIC rim housing, which accepts 6 and 7 pin small format interchangeable cores. A locksmith rekeying the opening and a technician replacing a worn bottom latch are ordering two different parts.
