Von Duprin 24231516 – Frequently Asked Questions

1) My doors have a 1 inch undercut for carpet clearance. Is this the right spacer kit?
No. The 24231516 kit is built for a 3/4 inch undercut specifically. If your opening was cut deeper for carpet or a mat, this kit spaces the device to the wrong height and the bottom latch won't land where it should. Measure the actual gap from the bottom of the door to the finished floor before you order, and get the spacer kit that matches that dimension.
2) Can I use the 24231516 spacer block kit on a fire rated exit device opening?
The 24231516 spacer block kit is not fire rated. Fire rated openings are also a poor match for an undercut condition in the first place, since fire doors have tight undercut limits and a labeled assembly has to stay as tested. On a labeled opening, keep the device and all of its parts to what the manufacturer's fire listing covers.
3) My exit device won't latch at the bottom on a door with a big floor gap. Is a spacer kit the fix, or do I need a new latch?
Check the cause before you buy either. If the door was undercut and the device is the original build, the device is sitting too high relative to the floor strike and a spacer kit sized to the undercut is the correct fix, 24231516 if that undercut is 3/4 inch. If the bottom latch itself is worn or damaged, spacing it won't help and the latch is the part to replace. Latch components are brand and series specific, an Accentra 7110/7120 top latch, for example, only serves Accentra devices, not Von Duprin.
4) My exit device will not latch at the top - do I need the Von Duprin 24231516 spacer block kit or a latch part?
A top latch that will not engage is a latching component question, not a spacer question. The Von Duprin 24231516 spacer block kit addresses a 3/4 inch door undercut so the 33, 35, 98 or 99 Series device is spaced and aligned on the door. Parts that address the top latch itself are separate items - the Accentra 60-7010-0049-999 is a top latch replacement component for 7110 and 7120 exit devices, and the Accentra 60-7010-0050-999 is the top latch replacement for the 7110F, both non fire rated, and the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices. Those are brand and series specific, so match the part to the device already hanging on the door rather than to the symptom.
5) Is the Falcon 4023 steel mullion an alternative to the Von Duprin 24231516 spacer block kit?
No - they solve different problems and are not interchangeable. The Von Duprin 24231516 is a spacer block kit for 33, 35, 98 and 99 Series exit devices, used where a 3/4 inch door undercut condition has to be accommodated so the device sits and aligns correctly on the door. The Falcon 4023 is a steel mullion for double door exit device applications - it is the removable vertical member that stands between a pair of doors and gives each leaf something to latch into. If the opening is a single door with an undercut, the spacer block kit is the part in play; if it is a pair of doors needing a strike point, the mullion is a separate purchase and does nothing about undercut clearance.
6) Is this a genuine Von Duprin part or an aftermarket spacer?
Genuine Von Duprin, part number 24231516, sold as a factory replacement component for the 33/35/98/99 Series. For a distributor or a spec-driven job where the submittal calls for Von Duprin hardware, that matters, an aftermarket shim doesn't carry the part number and won't match on a closeout list.
7) Is the Von Duprin 24231516 spacer kit rated for high traffic commercial use?
It's a Grade 1 commercial part, which is the heaviest duty tier for door hardware and what you'd want on a school, hospital or office exit that cycles all day. It is not a residential item.
8) Does the 24231516 kit come with the vertical rods, or do I order those separately?
Spacer blocks only. The kit addresses the undercut condition and nothing else, so rods, latches and strikes are separate line items. If you're chasing a rod for a different brand's device, that's a different part entirely, the Falcon 610061 top rod, for instance, fits Falcon 24 Series Monarch F-25-C and F-25-CWDC concealed vertical rod devices and has nothing to do with Von Duprin.
9) I'm standardizing exit device parts across a building. Do I need a different spacer kit for every door?
You need one kit per device that sits on an undercut door, and the kit has to match the undercut depth. Where the undercut is a consistent 3/4 inch across a run of openings, 24231516 covers all of them regardless of whether the devices are 33, 35, 98 or 99 Series. Doors with no undercut, or a different undercut, don't take this kit. Walk the building and record the floor gap door by door before you build the order.
10) I searched Von Duprin exit device spacer and got Falcon 525 mullion stabilizers - are those the same thing?
They are not. The Falcon 525 is an aluminum mullion stabilizer, a bracket that steadies a mullion in the opening; it is an exit device accessory but it mounts to the mullion, not to the door face. The Von Duprin 24231516 is a spacer block kit that shims the 33, 35, 98 and 99 Series exit device to suit a 3/4 inch undercut door, keeping the device positioned and aligned. Both words - spacer and stabilizer - show up in exit device accessory searches, so for a locksmith ordering against a service call the deciding question is whether the complaint is device alignment on an undercut door, which is the 24231516, or a mullion that moves in the frame, which is the 525.
11) Is a deadlatch part like the Falcon 23981160 what I need for an exit device that sits wrong on an undercut door?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part in the T Series line - a latch body that goes into the door edge prep. A device sitting wrong because of door undercut is a mounting and spacing condition, which is what the Von Duprin 24231516 spacer block kit is made for on 33, 35, 98 and 99 Series exit devices at a 3/4 inch undercut. Changing a latch will not correct device height or alignment on the door face, and the two parts do not share a series or a prep.
