Von Duprin 900581 – Frequently Asked Questions

1) What exactly comes in the Von Duprin 900581 package?
The 900581 is a two-piece service kit: the cylinder cup and the tailpiece lead, supplied together as one package. It is the cylinder-side hardware only, so it does not include a cylinder, a key, or any latch or chassis parts. If a cylinder is turning without operating the device, this is the pair of parts that carries that motion.
2) My exit device cylinder turns but the latch doesn't retract. Is the tailpiece the part to replace?
On a 210K or 230L device, that symptom usually traces to the tailpiece lead or a worn cylinder cup, and the 900581 replaces both together. It restores the mechanical link between the cylinder and the device without touching the cylinder itself, so existing keys and keying stay as they are.
3) Do I have to rekey or buy a new cylinder when I install the 900581?
No. The cylinder cup and tailpiece lead are the carrier hardware between your cylinder and the exit device, not the lock cylinder. Your existing mortise cylinder and its keyway, keying and master key system carry over, which is what makes this a straightforward service repair on a building already keyed to a system.
4) Is a genuine Von Duprin part worth it over a generic cylinder cup and tailpiece?
The 900581 is OEM Von Duprin, matched to the 230L and 210K geometry, so the cup seats and the lead engages without filing or shimming. A generic tailpiece cut to length is a common field fix and a common callback, because the engagement depth on these devices is what fails first. It is also a heavy-duty commercial part, which matters on a door cycling all day.
5) How do I order the Von Duprin 900581, and is there more than one version?
One configuration only, ordered as Von Duprin part number 900581, the 210/230 Series cylinder cup and tailpiece lead package. There is no finish, handing or length choice to specify, so the only thing to confirm on the order is that your device is a 210K or 230L.
6) I manage several buildings with Von Duprin exit devices. Should I stock the 900581 on the shelf?
It is worth stocking if your openings run 210K or 230L devices. The cylinder cup and tailpiece are wear items on high-traffic doors, and holding the matched pair means a maintenance tech restores the opening in one visit rather than diagnosing, ordering, and returning. On devices from other Von Duprin families it will not help you, so match the stock to what is actually hung.
7) Is the Von Duprin 900581 a residential part or is it for commercial doors?
Commercial only, and rated heavy duty. It is service hardware for exit devices on egress openings in offices, schools, hospitals, retail, warehouses, multi-tenant residential buildings and government facilities, not for a house door.
