BEST BES-12E62-C4RP3626-PC – Frequently Asked Questions

1) Will a BEST 12E rim cylinder work on a rim exit device that isn't BEST?
Yes. The 12E Series rim cylinder is interchangeable with other manufacturers' rim cylinders, so it can replace a non-BEST rim cylinder on a rim exit device. It ships with the RP3 ring package, 1E-S2 spindle, clamp plate and clamp plate screws, which is what you need to mount it and set the tailpiece to the device.
2) Can a BEST 12E rim cylinder be keyed into our existing BEST master key system?
That's the point of it. The 12E takes a BEST interchangeable core, so it can be masterkeyed into any existing BEST system. You pick the keyway when ordering (WA, WB, WC, WD, WE, WG, WH, WK or WY) and give us the keymark and marking number so the core is cut to your system rather than keyed at random.
3) What's the difference between the 6-pin and 7-pin BEST 12E cylinder, and which do I order?
Order the pin count that matches the cores already in your building. BEST systems are built as either 6-pin or 7-pin, and a core of one depth will not key into a system built on the other. The 12E is offered in both, along with matching 6-pin mortise and 7-pin mortise ring options. If you're starting fresh, pick one and standardize the whole facility on it.
4) I need a cylinder for an Adams Rite MS deadlock. Does the BEST 12E cover that?
Yes, order it with the Adams Rite MS cam instead of the standard cam. That cam is what drives an Adams Rite MS deadlock; the standard cam will not throw it. The third option, standard spindle, is the rim configuration for a rim exit device. If you'd rather use a native Adams Rite cylinder, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin unit for a 1/2 inch minimum door thickness.
5) What do I have to specify when ordering a BEST 12E interchangeable core cylinder?
Four things decide the part. Keyway (WA, WB, WC, WD, WE, WG, WH, WK or WY), your keymark and marking number so the core matches your system, 6-pin or 7-pin, the cam or spindle (standard cam, Adams Rite MS cam, or standard spindle), the ring to suit the application (rim cylinder, tapered cylinder, 3E mortise, 6-pin mortise or 7-pin mortise), and the finish. Miss the keymark and the core comes keyed outside your system.
6) Will the 1-5/32 inch BEST 12E cylinder drop into a standard rim cylinder prep?
Yes. The 12E is a 1-5/32 inch diameter rim cylinder, which is the standard rim cylinder size, so it fits standard rim cylinder applications without reworking the door or the device chassis. The body is machined from solid bar stock.
7) We don't run a BEST key system. Is there a rim cylinder that fits our Schlage keying instead?
The BEST 12E is built around the BEST interchangeable core and its WA through WY keyways, so it belongs in a BEST-keyed building. If your facility is on Schlage, the Schlage Commercial 20-021 rim cylinder is a 6-pin with a vertical tailpiece cam and the 20-022 is the same with a horizontal tailpiece cam. Both ship with two keys. For a full size interchangeable core instead of a conventional cylinder, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
8) What is the closest equivalent to a BEST 12E rim cylinder from Schlage?
The Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, which is the nearest equivalent in concept: an interchangeable core rim cylinder rather than a fixed-core one. The BEST 12E rim cylinder uses BEST's interchangeable core system and can be masterkeyed into an existing BEST system, and it ships with the cylinder, RP3 ring package, 1E-S2 spindle, clamp plate and clamp plate screws. The difference that decides it is the core platform: a BEST-keyed facility stays on BEST small format cores, while the 20-057 takes Schlage full size interchangeable cores. If you need the Schlage core itself rather than the housing, the 20-057-C is a full size interchangeable core in C keyway, 643E Aged Bronze.
9) If I do not need interchangeable cores, what is a simpler rim cylinder to use instead of the BEST 12E?
A fixed-core rim cylinder covers the same opening without the core-swap capability. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and 2 keys. The Corbin Russwin 3070-178 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece from the 3000 series. The BEST 12E is the choice when the cylinder has to drop into a BEST master key system, since its core is interchangeable and may be masterkeyed into any existing BEST system; the fixed-core options are keyed as supplied. With the Schlage pair, confirm whether your exit device wants the vertical or horizontal cam before ordering.
10) The door has a mortise lock, not a rim exit device. What should I order instead of a BEST 12E rim cylinder?
A rim cylinder will not serve a mortise lock case; a mortise cylinder threads into the lock body and turns a cam. The Corbin Russwin CR1000-112 is a Grade 1 series mortise cylinder, 1-1/2 inch length, with an A02 straight cam. The CR1070-114-A01 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. For an interchangeable core mortise application, the CR1080-112-A01 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 Schlage L cam. Match the cam to the lock you are feeding, since the cam is what moves the retractor. The BEST 12E family does include mortise ring options, so if you are staying on BEST cores, specify the 3E Mortise, 6-pin Mortise or 7-pin Mortise ring rather than the Rim Cylinder ring.
11) Is an Adams Rite cylinder pull a substitute for a BEST 12E rim cylinder on an aluminum storefront door?
No. A cylinder pull is a pull handle assembly that carries a cylinder, not a standalone rim cylinder. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the Adams Rite 5017 wood door deadlock. Those replace the outside pull and cylinder together on a specific Adams Rite deadlock. The BEST 12E is the cylinder alone, machined from solid bar stock at 1-5/32 inch diameter, and it is offered with an Adams Rite MS Cam option for feeding an MS deadlock, so on a storefront it goes behind existing trim rather than replacing the pull.
12) Our building is standardized on Schlage C keyway. What cylinder matches that instead of a BEST keyway?
The BEST 12E is ordered in a BEST keyway -- WA, WB, WC, WD, WE, WG, WH, WK or WY -- so it belongs on a facility keyed to BEST. To stay on Schlage C, the Detex MC65 is a mortise cylinder with Schlage C keyway, 1-1/8 inch, 6-pin, commercial grade, and the Schlage 20-057-C is a full size interchangeable core in C keyway with a 643E Aged Bronze finish. Pick by the lock the cylinder feeds: the MC65 threads into a mortise case, while the 20-057-C is the core that drops into a Schlage FSIC housing such as the 20-057 rim cylinder.
13) Which ring do I order with a BEST 12E cylinder?
Match the ring to the hardware it's going into. Rim cylinder ring for a rim exit device, tapered cylinder ring where the trim needs a tapered collar, and 3E mortise, 6-pin mortise or 7-pin mortise rings when the cylinder is going into a mortise prep. The cylinder also comes with the RP3 ring package as standard, so check what's on the door before adding a different ring.
14) Is an interchangeable core rim cylinder worth it over a conventional rim cylinder?
It comes down to how often you rekey. With the BEST 12E, a control key pulls the core in seconds and a new core drops in, so a tenant turnover or a lost key is a core swap at the door, no disassembly and no locksmith pinning on site. A conventional rim cylinder like the Corbin Russwin 3070 6-pin housing with a 1-7/8 inch tailpiece has to come off the door and be repinned. If you're managing a handful of doors, conventional is fine. Across a portfolio of units, the core system pays for itself.
15) Can one BEST 12E cylinder be used for both rim and mortise applications on the same job?
Not as a single part number, no. The 12E is ordered as a rim cylinder with a spindle or cam, and the ring you select sets the application. What does carry across is the core: the same BEST interchangeable core keying runs through your rim and mortise hardware, so one key and one master system covers both even though the cylinder bodies differ. If you need a dedicated mortise cylinder on the same job, the Corbin Russwin 1080 is a 1-1/2 inch LFIC 6-pin mortise cylinder for Schlage L9000 mortise locks with an A01 cam.
16) What comes in the box with the BEST 12E rim cylinder, and what else do I need to buy?
The package is the cylinder, the RP3 ring package, the 1E-S2 spindle, the clamp plate and the clamp plate screws, so it's ready to mount. What is not in the box is the keying decision: you specify keyway, keymark and marking number when you order so the core arrives cut to your system. Cams and rings are selections on the order, not extras added later.
17) Will a BEST 12E rim cylinder retrofit a residential deadbolt or handleset?
That is a different cylinder pattern. Residential deadbolts and handlesets generally take a lazy-motion rim type cylinder with a tailpiece matched to the lock brand. The Medeco 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, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the Emtek CY4 is a single Emtek cylinder. The BEST 12E is the interchangeable core rim cylinder for commercial rim hardware, with a standard cam or Adams Rite MS cam and a standard spindle.
18) Which cylinder should I use if the opening needs a Grade 1 rated cylinder for an Adams Rite deadlock?
The Adams Rite 4036 mortise cylinder with five-pin security is listed as Grade 1 in the 4036 series, with a 1/2 inch minimum door thickness. That is the one to specify when the drawing calls out a Grade 1 cylinder on an Adams Rite deadlock in a thin stile. The BEST 12E takes a different route to the same opening: it is a 1-5/32 inch diameter rim cylinder available with an Adams Rite MS Cam, so it feeds the MS deadlock while keeping the door on BEST interchangeable cores and inside an existing BEST master key system. Choose by what governs the job -- the stated Grade 1 callout, or keying continuity across the facility.
19) I am rekeying knobs and levers, not exit devices. Does the BEST 12E fit, or do I need a different cylinder?
Key-in-knob and key-in-lever cylinders are a separate part from a rim cylinder and are not interchangeable with one. The Kaba Ilco 1539 is a key-in-knob / lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder for Sargent. The Falcon A23161-05 G is a key in lever cylinder for the RU/T series with a 6-pin G keyway, keyed different, supplied with 2 cut keys. For a deadbolt instead, the Kaba Ilco 1549 is a key-in-deadbolt cylinder. The BEST 12E stays on the rim exit device and MS deadlock side of the job, in 6-pin and 7-pin types, and carries the BEST interchangeable core so the same key system covers it.
20) What is the difference between a BEST 12E small format interchangeable core cylinder and a Schlage full size interchangeable core?
Both let a locksmith pull and replace the core without removing the cylinder, but the cores are not cross-compatible. The BEST 12E uses the BEST interchangeable core system in 6-pin and 7-pin types and can be masterkeyed into any existing BEST system. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, taking a full size core such as the 20-057-C in C keyway. The Corbin Russwin CR1080-112-A01 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 cam, which is a third core format again. Decide on the cores already in the building, because that determines which housings the maintenance stock of cores will fit.
21) What finishes does the BEST 12E rim cylinder come in, and will it match our existing door hardware?
Ten finishes, all standard BHMA numbers, so you can match what is already hung: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome and 690 statuary dark bronze. Read the number off the existing lock or exit device trim and order to match; 626 satin chrome and 630-family stainless trims are the common commercial pairing.
22) Is the BEST 12E rim cylinder durable enough for a high traffic commercial entrance?
The cylinder body is machined from solid bar stock rather than cast, which is what holds up on an entrance door taking constant key cycles. It's used in office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities.
