Falcon A12689-000-00 EACH – Frequently Asked Questions

1) What exactly is the Falcon A12689 and what does it do in a rim cylinder?
The A12689 is a tailpiece, not a cylinder. It is the flat bar that transfers rotation from the small format interchangeable core to the locking mechanism behind the door, and Falcon builds it for their rim housing cylinder assemblies. If your core turns with the key but the device does not retract, the tailpiece is the part to look at.
2) Do I have to replace the whole Falcon rim cylinder, or can I just swap the tailpiece?
If the housing and core are sound, the tailpiece alone can be replaced. That is what the A12689 is for, a targeted repair on an installed Falcon rim cylinder assembly rather than pulling the full unit off the door. A bent or worn tailpiece is one of the more common service items on SFIC rim hardware.
3) What is the difference between needing the Falcon A12689 tailpiece and needing a full-size interchangeable core cylinder?
The A12689 serves Small Format Interchangeable Core rim housings, where the core is the compact SFIC figure-eight style. If the opening uses full size interchangeable cores instead, the parts are not interchangeable - Schlage's 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish. Confirm whether the housing in the door is SFIC or FSIC before ordering.
4) If the rim cylinder housing itself is damaged and not just the tailpiece, what should be ordered instead of the Falcon A12689 tailpiece?
The Falcon A12689 is only the tailpiece that transfers motion from a Small Format Interchangeable Core to the locking mechanism in a Falcon rim housing, so it does nothing for a damaged housing. For a complete rim housing, the Corbin Russwin 3070 is a 6-pin rim cylinder housing supplied with a 1-7/8 inch tailpiece, and Schlage offers the 20-021 rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, each 6-pin and supplied with two keys.
5) Does the Falcon A12689 include a core, or is a separate interchangeable core needed?
The A12689 is a replacement tailpiece only - it is the engagement link between the core and the lock mechanism, not a keyed core. Interchangeable cores are ordered separately: the BEST 1C series is a standard 5-pin cylinder core, the BEST 1CB is a Peaks 150 series interchangeable core, and the BEST 1CDF is a drill-resistant patented 7-pin brass 150 series interchangeable core.
6) What part number do I order for a Falcon SFIC rim housing tailpiece?
Order Falcon model A12689-000-00, sold each. It is a genuine Falcon component made to the original specification for their rim housing cylinders, which matters here because tailpiece length and bar geometry are what determine whether the core engages the device correctly.
7) Does the A12689 include a core or keys?
No. It is the tailpiece on its own. The SFIC core and keying are separate, so if you are also replacing the core you need to source that as well, for example a BEST 1C Series standard 5-pin interchangeable core or a 1CB 150 Series core.
8) The Falcon A12689 tailpiece will not work on a mortise lock - what cylinder suits a mortise prep?
Correct, the A12689 is built for rim housing configurations, and rim and mortise cylinders engage the lock differently. Mortise applications call for a mortise cylinder such as the Corbin Russwin 1000 Grade 1 series in 1-1/2 inch length with an A02 straight cam, the 1070 Grade 1 series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, or the Adams Rite 4036 Grade 1 five-pin mortise cylinder.
9) Is a lazy-motion rim cylinder a substitute for a Falcon rim housing with the A12689 tailpiece?
No. The A12689 tailpiece is matched to Falcon SFIC rim housing assemblies for commercial door hardware. Lazy-motion rim cylinders are built around specific residential-style lock bodies instead - the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin lazy motion single cylinder for handlesets and deadbolts. Those tailpieces are integral to the cylinder and are not a Falcon SFIC replacement.
10) For a rim housing on an aluminum storefront with a deadlock, is the Falcon A12689 the right part?
The A12689 addresses the tailpiece inside a Falcon SFIC rim housing and assumes that housing is already in the door. Narrow stile storefront deadlocks are usually served by a cylinder pull matched to the lock body instead: the Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five-pin cylinder pull with through-screws for the same MS1847, and the 4026 is a five-pin cylinder pull for the 5017 wood door deadlock and deadlatch.
11) Is the Falcon A12689 tailpiece suitable for commercial buildings or is it a residential part?
It is a commercial part. Falcon rates it for commercial door hardware, and the usual homes for it are offices, schools, hospitals, government buildings, retail, warehouses, and multi-tenant residential.
12) If a rim opening needs to look keyed but not operate, is the Falcon A12689 involved?
No. The A12689 exists to drive the lock mechanism, so it belongs in an operating rim housing. Where a rim location only needs the appearance of a cylinder, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter covers that, and it carries no tailpiece function to replace.
13) Can a universal key-in-knob replacement cylinder be used in place of repairing a Falcon rim housing with the A12689?
Those solve different openings. The A12689 restores a Falcon SFIC rim housing that is mounted on the surface of the door and drives a rim device. Key-in-knob and deadbolt retrofit cylinders replace the cylinder inside a knob, lever, or deadbolt body - the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1549 is a key-in-deadbolt cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. None of those fit a rim housing.
14) For a facility standardizing on a single keyway across mortise openings, does the Falcon A12689 factor in?
The A12689 is keyway-neutral - it is the tailpiece, and the keying lives in the SFIC core dropped into the Falcon rim housing. Keyway decisions are made at the cylinder or core: the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in the Schlage C keyway, and the Schlage 20-057-C is an FSIC core in the C keyway. Standardize at that level and use the A12689 purely to keep existing Falcon rim housings operating.
