Falcon 030917-003-30 – Frequently Asked Questions

1) What does the Falcon 030917-003 tailpiece actually do, and is it a cylinder or just the driver?
It's the tailpiece only, not a cylinder. The Falcon 030917-003 is the OEM driver that transfers key rotation from an inside cylinder into the lock body on RU/T applications. If you need the keyed cylinder itself, this isn't it, you're buying the small service part that makes the cylinder engage the lock correctly.
2) Will the Falcon 030917-003 tailpiece work with a Yale large format interchangeable core?
Yes, it's built for Yale 1801, Yale 5801, and Yale 6-pin LFIC cylinder configurations. That covers the common Yale large format interchangeable core setups used in commercial master keying, so if your building is keyed on Yale LFIC and the lock is a Falcon RU/T, this is the correct tailpiece.
3) Is this an inside or outside cylinder part?
Inside. The 030917-003 is specified for the inside cylinder position on RU/T applications. For the outside cylinder, a different tailpiece is used, so confirm which side of the lock you pulled the broken part from before ordering.
4) Is the Falcon 030917-003 tailpiece a substitute for a complete replacement cylinder?
No. The Falcon 030917-003 is a replacement tailpiece for RU/T inside cylinders, a service part that restores cylinder-to-lock-body engagement rather than a keyed cylinder itself. If the cylinder body or keying needs to be replaced rather than just the tailpiece, a complete unit is the right call: the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder.
5) My application is a rim device, not an RU/T inside cylinder. What cylinder fits instead?
The Falcon 030917-003 tailpiece is built for the inside cylinder position on RU/T applications, so it will not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece.
6) Which Falcon series do I pick for the 030917-003 tailpiece?
Two series choices: T381 and T571. Pick the one matching the Falcon lock you're servicing, since the series is what determines which orderable part you get.
7) Do I have to modify the lock to install the Falcon 030917-003?
No modification. It's a like-for-like OEM drop-in that restores original factory function on the existing Falcon assembly, so a maintenance tech swaps it in without drilling or filing anything.
8) I need the whole cylinder, not a tailpiece. What interchangeable core options are there?
For a full core rather than a driver part, look at the BEST 1CB 150 Series interchangeable core cylinder or the BEST 1C Series standard 5-pin core. If you're in a Schlage full-size interchangeable core system instead, the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam covers that. The Falcon 030917-003 is only the tailpiece and will not replace any of those.
9) Is a Corbin Russwin 3070 rim cylinder with a 1-7/8 inch tailpiece a substitute for this Falcon part?
No. The Corbin Russwin 3070 is a complete 6-pin rim cylinder housing that happens to include a 1-7/8 inch tailpiece; it is a rim cylinder, not a Falcon RU/T inside service part. Buying it will not fix a broken tailpiece inside a Falcon lock body. Order the Falcon 030917-003 for that repair.
10) I need a keyed mortise cylinder with a straight cam instead of an LFIC housing. What are my options?
The Falcon 030917-003 addresses only the tailpiece on RU/T inside cylinders. For a keyed mortise cylinder, the Corbin Russwin 1000 Grade 1 Series is 1-1/2 inch with an A02 straight cam, while the Corbin Russwin 1070 Grade 1 Series 1-1/4 inch 6-pin housing uses an A01 cloverleaf cam. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway.
11) What is the difference between the Falcon 030917-003 tailpiece and an interchangeable core?
They are different halves of the same assembly. The Falcon 030917-003 is the tailpiece that transmits cylinder rotation to the lock body on RU/T inside cylinders. An interchangeable core carries the pinning and keyway: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1C5 is a standard 5-pin cylinder core, and the BEST 1CDF is a drill resistant patented 7-pin brass interchangeable core in the 150 Series. If the key needs to change, you are replacing a core; if the lock will not actuate, you are replacing a tailpiece.
12) Will the Falcon 030917-003 work on an aluminum storefront deadlock?
No. The Falcon 030917-003 is a Falcon service tailpiece for RU/T inside cylinders with Yale 1801, 5801 and 6-pin LFIC cylinders, not a storefront part. For narrow stile storefront deadlocks, the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both designed for the Adams Rite MS1847 deadlock/deadlatch; the Adams Rite 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch.
13) Is there a residential-grade alternative to the Falcon 030917-003 tailpiece?
The Falcon 030917-003 is a commercial part for RU/T inside cylinders on Falcon mechanical lock assemblies. Tailpiece-equipped cylinders built for residential handlesets and deadbolts are a different family: the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
14) Which cylinder do I use for a Sargent or Arrow lock rather than a Falcon RU/T?
The Falcon 030917-003 tailpiece is matched to Falcon RU/T inside cylinder applications with Yale 1801, 5801 and 6-pin LFIC cylinders, and it is supplied for the T381 and T571 series. For other manufacturers' locks, the Kaba Ilco 1579 Series is a knob and lever cylinder for Sargent, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
15) What looks like a tailpiece part but will not restore lock function on an RU/T cylinder?
A dummy cylinder will not. The BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a prep and accepts no key operation, and the Emtek CY4 cylinder is a handleset-family part sold each. Neither takes the place of the Falcon 030917-003, which is the OEM tailpiece that carries rotation from an RU/T inside cylinder into the Falcon lock body.
16) Is the 030917-003 rated for commercial use or is it a residential part?
Commercial. It's classed as a commercial door hardware component and is the part locksmiths and in-house maintenance crews use when servicing Falcon mechanical locks in offices, schools, hospitals, government buildings, retail, and multi-tenant properties keyed on LFIC systems.
17) Is the Falcon 030917-003 a genuine Falcon part or aftermarket?
Genuine OEM Falcon. It's sourced as a Falcon lock part and machined to the factory spec for the RU/T inside cylinder position, which matters when you're keeping engagement tolerances right on a high-cycle commercial opening.
18) What model number should I reference when ordering this Falcon tailpiece?
Reference Falcon 030917-003, model 030917-003-30, and state the series you need, T381 or T571. Distributors ordering for stock should carry both series designations since they are not interchangeable line items.
19) We are standardizing a facility on one keyway. Does the Falcon 030917-003 affect that decision?
The Falcon 030917-003 is a tailpiece, so it carries no keyway of its own; it serves RU/T inside cylinders using Yale 1801, 5801 and 6-pin LFIC cylinders, which is where the keying lives. Keyway is selected at the cylinder or core: the Schlage 20-057-C is a full size interchangeable core in the C keyway with a 643E aged bronze finish, and the Detex MC65 mortise cylinder is also supplied in the Schlage C keyway.
