Falcon A12635-002-00 – Frequently Asked Questions

1) What does the Falcon A12635-002-00 top pin fit?
It's a top pin for the Falcon A2 cylinder system, sold as a genuine Falcon service part for commercial mechanical lock cylinders. It goes in the top of the pin stack, above the bottom pin, and is what you replace or re-size during rekeying and cylinder rebuilds on A2 system hardware.
2) Can I use these top pins in a Schlage or BEST cylinder instead of Falcon?
No. The A12635-002-00 top pin is cut to the Falcon A2 system's pin stack tolerances, and pin diameters and length increments differ between manufacturers' systems. For other platforms, buy that brand's cylinder or core outright, such as a BEST 1C Series 5-pin core or a Schlage 20-057 full size interchangeable core, rather than mixing pins.
3) Is this a complete cylinder or just a pin?
Just the top pin, sold loose in bulk. It contains no housing, plug, springs, cam or keys. If you need a whole cylinder rather than a service part, look at a complete unit such as the Corbin Russwin 1000 Grade 1 mortise cylinder with A02 straight cam or a Schlage 20-021 rim cylinder.
4) Will the Falcon A12635-002-00 top pin work in a Schlage or Corbin Russwin cylinder instead of a Falcon A2?
No. The Falcon A12635-002-00 is a top pin built specifically for the Falcon A2 cylinder system, and its length and tolerance belong to that pin stack. If the housing on the bench is a Schlage rim cylinder such as the 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, or a Corbin Russwin mortise housing such as the 1070 with the A01 cloverleaf cam, those are separate keying systems and need their own pinning components. Order Falcon A2 top pins for Falcon A2 cylinders only.
5) I need a complete cylinder, not pins. What should I order instead of the Falcon A12635-002-00?
The A12635-002-00 is a loose top pin sold as a bulk replacement part for rebuilding and rekeying Falcon A2 pin stacks, so it does not replace a cylinder on its own. For a finished cylinder, a mortise opening can take the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch with the A02 straight cam, and a rim device can take the Schlage 20-021 six-pin rim cylinder with a vertical tailpiece cam or the Corbin Russwin 3070 six-pin rim housing with a 1-7/8 inch tailpiece. Choose by the prep in the door and the cam or tailpiece the lock requires.
6) How many pins come in a pack of Falcon A12635-002-00 top pins?
They ship 100 to a pack, one size per pack. That quantity is aimed at locksmiths and in-house maintenance shops keeping a pinning kit stocked rather than buying for a single cylinder.
7) Are Falcon A2 top pins suitable for a large facility rekeying program?
Yes. The pin is rated for commercial mechanical lock work, and 100-count bulk packs per size are what a school, hospital, office or municipal building keeps on the shelf so cylinders can be rekeyed in-house without pulling hardware out of service waiting on parts.
8) Do I need more than one size of A2 top pin to rekey a cylinder?
Usually yes. Every chamber in the plug takes a top pin sized to complement that chamber's bottom pin, so a full rekey across a keying system draws on several of the 2 through 19 sizes. Most shops stock a spread of sizes rather than a single pack.
9) Instead of stocking Falcon A2 top pins to rekey by hand, can I move the facility to interchangeable cores?
That is the other way to handle rekeying. The Falcon A12635-002-00 top pin supports pin-stack work on existing Falcon A2 cylinders, which keeps the housings in the doors and changes the pinning. An interchangeable-core program swaps the core instead: the BEST 1CB 150 Series interchangeable core cylinder or the BEST 1CDF drill-resistant patented seven-pin core in brass covers that approach, and Schlage offers the 20-057 six-pin FSIC rim cylinder with a convertible tailpiece cam for full-size cores. Pin stock keeps your current hardware; cores change the hardware and the service method.
10) My key-in-knob and deadbolt cylinders are failing, not the pin stacks. What do I use rather than Falcon A2 top pins?
Top pins like the A12635-002-00 are for rebuilding Falcon A2 pin stacks, so they do not help a worn knob or deadbolt cylinder body. For those, Kaba Ilco offers the 1539 Series key-in-knob and lever universal cylinder, the 1549 Series key-in-deadbolt cylinder, and the 1599 key-in-knob replacement cylinder, with the 1579 knob and lever cylinder made for Sargent locks. Pick by the lock body being served and confirm the keyway you are keying to.
11) Is a BEST 1C5 cylinder core an alternative to buying Falcon A2 top pins?
They solve different parts of the job. The BEST 1C5 is a standard five-pin cylinder core, a complete keyed unit, while the Falcon A12635-002-00 is a bulk top pin used inside a Falcon A2 cylinder during rekeying or a rebuild. If your openings carry Falcon A2 cylinders that stay in place, the top pins are the consumable you restock; if you are replacing keyed units outright in BEST-prepped hardware, the 1C5 core is the item.
12) Which cylinder should I use instead if the opening is an Adams Rite aluminum storefront deadlock?
Falcon A2 top pins are service components for Falcon A2 cylinders and do not address storefront hardware. For Adams Rite openings, the 4036 mortise cylinder is a Grade 1 five-pin unit with a 1/2 inch minimum door thickness, and the 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws are both made for the Adams Rite MS1847 deadlock and deadlatch. Wood door deadlocks in the 5017 family take the 4026 five-pin cylinder pull instead.
