Schlage 09-417 – Frequently Asked Questions

1) What is the Schlage 09-417 and what does it contain?
The Schlage 09-417 is a bulk pack of ten C604-243 cylinder tailpieces. The tailpiece is the flat metal bar that runs from the back of the cylinder into the knob's retractor, transferring key rotation to the latch. You get ten in the pack, so it suits a locksmith or maintenance shop rekeying or rebuilding several cylinders at once rather than buying one part at a time.
2) Will the C604-243 tailpiece fit a Schlage D Series knob lock?
Yes, that is exactly what it is cut for. The C604-243 is specified for D Series knob non-modular conventional cylinders. If your D Series knob uses a conventional (non-modular) cylinder, this is the matching tailpiece.
3) Can I use this tailpiece on a Schlage modular cylinder?
No. The 09-417 tailpieces are made for non-modular conventional cylinders in the D Series knob platform. Modular cylinders use a different tailpiece arrangement, so ordering this pack for a modular cylinder will leave you with a part that does not engage correctly. Confirm whether the cylinder in the door is conventional or modular before you order.
4) Is this an aftermarket tailpiece or a genuine Schlage part?
Genuine Schlage. The C604-243 is an authentic Schlage component supplied under part number 09-417, which matters on a tailpiece because a hair of difference in blade thickness or length shows up as a key that turns but will not retract the latch.
5) My key turns in the D Series knob but the latch will not pull back. Do I need this part?
That symptom usually points at the tailpiece, which is the link between the cylinder plug and the knob's retractor. A bent, worn, or broken C604-243 lets the key rotate with nothing moving behind it. The 09-417 pack is the replacement for that bar on D Series knob non-modular conventional cylinders, and because it comes ten to a pack you can keep spares on the truck for the rest of the building.
6) Do I have to replace the whole D Series cylinder, or can I just swap the tailpiece?
If the cylinder itself is sound and only the tailpiece is damaged, you replace the tailpiece alone. That is what this part is classified as, a replacement part for restoring existing D Series cylinder assemblies without pulling the full lockset off the door. Cheaper fix and no rekeying needed.
7) Is the 09-417 tailpiece suitable for commercial door hardware or only residential locks?
It is a commercial-grade part, built to Schlage's commercial product standards for D Series knob cylinders. D Series knobsets are the commercial cylindrical line used in offices, schools, healthcare, retail, warehouses, multi-tenant buildings and government facilities, and this tailpiece is the service part for those openings.
8) Can I buy a single 09-417 tailpiece instead of ten?
The 09-417 is sold as the 10-pack; that quantity is what the part number designates. For a property manager standardizing on D Series knobs across a building, the pack covers a run of cylinder work in one order.
