BEST BES-2C7A1605 – Frequently Asked Questions

1) Will a BEST 2C 7-pin core work in a standard BEST small format housing, or is it only for mailbox locks?
The 2C Series 7-pin core is built for 8L mailbox lock applications and is only compatible with high security mortise cylinders. It is not a general-purpose core for any BEST housing on the shelf. If you are coring standard commercial mortise, rim, or knob housings, this is the wrong part.
2) Do I need special keys for the BEST 2C 7-pin mailbox core?
Yes, this core takes long blade keys. Standard length BEST blanks won't reach the pin stack correctly, so order long blade keys in the same keyway as the core when you set up the system.
3) Can I order these BEST mailbox cores already keyed, or do they come uncombinated?
Both. The Type option is Combinated or Uncombinated. Order Combinated when you want BEST to pin the core to your system, and supply the keymark and marking number with the order so it drops into your existing masterkey scheme. Choose Uncombinated if your locksmith pins cores in house.
4) Is this the whole mailbox lock or just the core?
Core only. It is a replacement component that drops into a compatible 8L high security mortise cylinder housing. If your mailbox lock body is worn or the housing is damaged, you need the cylinder or lock as well, not just the core.
5) Is the Schlage 20-057 interchangeable core a substitute for a BEST 2C 7-pin core in an 8L mailbox lock?
No. The BEST 2C Series 7-pin core is built specifically for 8L mailbox lock applications and is only compatible with high security mortise cylinders, using long blade keys. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, so it is a rim-mounted device for a different housing, not a drop-in core for an 8L mailbox lock. If you are keying to a Schlage FSIC system, the 20-057-C ships as a full size interchangeable core in the C keyway, but neither part addresses an 8L mailbox opening.
6) What should I use instead of a BEST 2C 7-pin core if I need a conventional mortise cylinder for a door, not a mailbox?
The BEST 2C Series 7-pin core is a replacement core for 8L mailbox lock systems, not a complete mortise cylinder. For a door opening, the Corbin Russwin 1000 Grade 1 mortise cylinder comes in a 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 Grade 1 housing is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Match the cam to the mortise lock body you are feeding.
7) I need an interchangeable core solution for Schlage L9000 mortise locks instead of the BEST 8L core - what fits?
The Corbin Russwin 1080 Grade 1 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, listed for Schlage L9000 mortise locks with an A01 Schlage L cam. The BEST 2C Series 7-pin core is a different animal - it is a core for 8L mailbox lock systems and works only with high security mortise cylinders using long blade keys, so it will not serve an L9000 door lock.
8) For an aluminum storefront door, is the BEST 2C core or an Adams Rite cylinder the right call?
Adams Rite is the storefront answer. The 4036 mortise cylinder is a five-pin Grade 1 unit with a 1/2 inch minimum door thickness, and the 4024 and 4025 cylinder pulls are built for the Adams Rite MS1847 deadlock/deadlatch - the 4025 mounts with through-screws and the 4024 with a trim plate. For wood doors, the 4026 five-pin cylinder pull pairs with the Adams Rite 5017 wood door deadlock. The BEST 2C Series 7-pin core is dedicated to 8L mailbox lock systems.
9) Will 7-pin BEST cores key into the same master system as my 6-pin cores?
Plan the mailbox cores as their own segment. The 2C core is a 7-pin configuration with long blade keys, which is a different key length and pin stack than standard BEST cores, so it isn't a like-for-like swap into a 6-pin keying schedule. Hand the keymark to your BEST keying contact and have the mailbox openings written into the system properly.
10) I need a replacement cylinder for a commercial door, not a mailbox. What should I be looking at instead?
Stay away from the 2C mailbox core and pick a housing suited to the lock. For a mortise lock, the Corbin Russwin 1000 Series 1-1/2 inch mortise cylinder with an A02 straight cam, or the 1070 at 1-1/4 inch with an A01 cloverleaf cam. For an exit device, the Schlage 20-021 rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal cam. If you want interchangeable core convenience on a commercial opening, the Schlage 20-057 FSIC rim cylinder takes a full size core.
11) Is a BEST 2C core interchangeable with a Schlage full size core?
No. The Schlage 20-057-C is a full size interchangeable core on the Schlage C keyway and fits Schlage FSIC housings. BEST 2C cores use BEST keyways and, in this 7-pin mailbox version, long blade keys and 8L high security mortise cylinders. The two systems don't cross over, so pick one platform per facility.
12) Can I use a rim cylinder in place of the BEST 2C 7-pin mailbox core?
No - rim and core are different mounting formats. The BEST 2C Series 7-pin core drops into high security mortise cylinders on 8L mailbox locks. Rim options such as the Schlage 20-021 with a vertical tailpiece cam, the 20-022 with a horizontal tailpiece cam, and the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece all mount to the back of a rim device, typically an exit device or rim deadlatch.
13) Does a 6-pin cylinder like the Detex MC65 or Falcon A23161-05 G give the same keying as the BEST 2C 7-pin core?
No - the pin count and the system differ. The BEST 2C Series core is a 7-pin configuration offered across keyways A through R plus TB, TC, TD and TE, in combinated or uncombinated form. The Detex MC65 is a 6-pin mortise cylinder in the Schlage C keyway, and the Falcon A23161-05 G is a 6-pin key-in-lever cylinder in the G keyway supplied keyed different with 2 cut keys. Those are separate keying families and will not interchange with a BEST 7-pin masterkey system.
14) What is the simpler replacement cylinder option if I am rekeying knob or lever locks rather than mailboxes?
For key-in-knob and lever work, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, and the 1599 Series is a key-in-knob replacement cylinder; the 1549 Series covers key-in-deadbolt applications. The BEST 2C Series 7-pin core is a commercial replacement core aimed at 8L mailbox lock systems and masterkeyed BEST Standard systems, so it is the choice only when the mailbox hardware is what you are servicing.
15) If I want a high security retrofit cylinder for residential handlesets and deadbolts, what is the alternative to the BEST 2C core?
Medeco covers that side. The 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Emtek also lists the CY4 cylinder sold each. The BEST 2C Series 7-pin core is a commercial part for 8L mailbox lock systems.
16) What finishes do BEST 2C mailbox cores come in, and can I match my existing brass mailbox bank?
Eight finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome and 690 statuary dark bronze. For an older brass mailbox bank, 605 or 606 is the usual match; for chrome door fronts, 626 satin chrome.
17) Is this core rated for commercial mail centers and institutional use?
It is a commercial-duty core, used in office building mail centers, multi-tenant residential mail rooms, government and municipal mail facilities, campus and healthcare mail systems. The 7-pin stack gives more key combinations and better pick resistance than a lower pin count, which is why it shows up on tenant mailbox banks where key control matters.
18) I need to match existing finishes across a mail center - does the BEST 2C core offer more finish choices than the comparable cylinders?
The BEST 2C Series 7-pin core is offered in 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome and 690 statuary dark bronze. Among the alternatives, the Schlage 20-057-C full size interchangeable core is cataloged in 643E aged bronze. Confirm the finish code against the mailbox trim you are matching before ordering a batch.
