Falcon 030997-003-30 – Frequently Asked Questions

1) What does the Falcon 030997-003 tailpiece actually do, and is it a cylinder or just a part?
The Falcon 030997-003 is a tailpiece only, not a cylinder. It is the flat driver bar that transmits rotation from the cylinder plug into the lock body so the mechanism throws. If your cylinder itself is worn or you need a new keyed cylinder, this part will not cover you, you would order the cylinder separately and use this to link it to the lock.
2) Falcon T381 or T571, which tailpiece do I need?
The 030997-003 tailpiece is ordered against the Falcon series you are working on, T381 or T571. Pick the one matching the device already on the door, they are separate orderable selections and are not interchangeable choices made at random.
3) Is a rim cylinder with a tailpiece cam a substitute for the Falcon 030997-003 tailpiece?
No. The Falcon 030997-003 is a loose replacement tailpiece for RU/T inside trim paired with a Sargent 6/10 Line cylinder. Products such as the Schlage 20-021 rim cylinder with a vertical tailpiece cam, the 20-022 with a horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece are complete rim cylinders whose tailpiece is part of the assembly, prepped for rim exit device mounting rather than RU/T mortise trim. They are not interchangeable with a Falcon tailpiece.
4) If the cylinder itself is worn and not just the tailpiece, what replaces the whole unit for a Sargent-style knob or lever application?
The Falcon 030997-003 is a replacement tailpiece only - it transmits cylinder rotation to the lock mechanism in RU/T inside applications using Sargent 6/10 Line cylinders. If the cylinder body is the problem, a complete knob and lever cylinder made for Sargent is the Kaba Ilco 1579, which is a knob and lever cylinder for Sargent. Replacing the cylinder gets you a new plug and pins; the tailpiece alone only restores the drive connection.
5) The opening needs a keyed cylinder for a Schlage L9000 mortise lock, not a Falcon RU/T part. What is used there?
The Falcon 030997-003 tailpiece is built for RU/T inside applications with a Sargent 6/10 Line cylinder and will not serve a Schlage L-series mortise lock. For that opening the Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder is offered in 6-pin with an A01 Schlage L cam for Schlage L9000 mortise locks. Another Schlage-keyway option is the Detex MC65 mortise cylinder, 1-1/8 inch 6-pin with a Schlage C keyway.
6) Do I need to modify the lock to install this Falcon tailpiece?
No modification. The 030997-003 is drop-in replacement geometry for existing RU/T lock hardware, so it goes in against the original part with no filing or drilling. Pull the cylinder, swap the tailpiece, reinstall.
7) I'm doing an MRO order, what is the Falcon part number for the RU/T inside tailpiece?
Order it as Falcon 030997-003, model designation 030997-003-30. It is a genuine Falcon replacement part rather than an aftermarket copy, which matters if your facility standard requires factory components for traceability.
8) Will this Falcon tailpiece fit a rim cylinder on an exit device?
No. The 030997-003 is for RU/T inside use with a Sargent 6/10 Line cylinder, not rim hardware. Rim applications use their own tailpiece cam, for example the Schlage 20-021 rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal cam, and you would select by the cam orientation your exit device requires.
9) We want to stop stocking odd tailpieces and standardize on interchangeable cores instead. What are the options?
The Falcon 030997-003 tailpiece is a part-specific item tied to RU/T inside trim with a Sargent 6/10 Line cylinder, so it only fits that configuration. Facilities standardizing on a core-based program instead look at interchangeable core products such as the BEST 1CB 150 Series interchangeable core cylinder, the BEST 1CDF drill resistant patented interchangeable core 7-pin brass 150 Series, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. With a core program, rekeying is done by swapping cores rather than by servicing individual cylinder and tailpiece combinations.
10) For a mortise lock cylinder change, is a cam-style mortise cylinder used instead of a tailpiece part like the Falcon 030997-003?
Yes - mortise cylinders drive the lock through a cam rather than a tailpiece. Examples include the Corbin Russwin 1000 Grade 1 mortise cylinder at 1-1/2 inch with an A02 straight cam, the Corbin Russwin 1070 Grade 1 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the Adams Rite 4036 Grade 1 five-pin mortise cylinder. The Falcon 030997-003 is a tailpiece for RU/T inside applications with a Sargent 6/10 Line cylinder, so it addresses the drive connection in that specific trim rather than a cammed mortise cylinder swap.
11) Does a cylinder sold with a tailpiece already attached cover the same need as the Falcon 030997-003?
Only if the tailpiece matches the trim. The Falcon 030997-003 is sold as the tailpiece by itself for RU/T inside trim with a Sargent 6/10 Line cylinder, which is the right call when the cylinder is good and the drive piece is damaged. Cylinders that ship with their own drive hardware include the Medeco 1065244 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece and the Medeco 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders - but those tailpieces are matched to those locks, not to Falcon RU/T trim.
12) We need a non-keyed piece just to fill a cylinder hole. Is the Falcon 030997-003 the right part?
No. The Falcon 030997-003 is a functional tailpiece that transmits cylinder rotation to the lock mechanism in RU/T inside applications, so it assumes a working Sargent 6/10 Line cylinder behind it. For a non-functional fill, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy option. Choose by whether the opening needs to operate or only needs to look complete.
13) Is this Falcon tailpiece rated for commercial door traffic or is it a residential part?
Commercial. Falcon lists the 030997-003 as a commercial part under its mechanical lock program, which is why you see it specified in schools, hospitals, municipal buildings and multi-tenant properties keeping Sargent 6/10 Line cylinders in service.
14) What is used for a keyed deadbolt or key-in-knob cylinder swap rather than a Falcon tailpiece?
The Falcon 030997-003 is a commercial replacement tailpiece for RU/T inside trim with a Sargent 6/10 Line cylinder. For deadbolt and key-in-knob cylinder replacement, the Kaba Ilco line covers those functions: the 1539 key-in-knob and lever universal cylinder, the 1549 key-in-deadbolt cylinder, and the 1599 key-in-knob replacement cylinder are each listed with a deadbolt product function. Those are complete cylinders for the lock body, not a tailpiece for existing Falcon RU/T trim.
