BEST BES-12E02-RP3626 – Frequently Asked Questions

1) What is a dummy rim cylinder actually for, and will it lock the door?
It will not lock anything. A dummy cylinder is a non-functional cylinder that fills the hole so the opening looks like the others beside it, with no operating function behind it. Common on the inactive leaf of a pair, on a door where the exit device is push-only, or where an old keyed rim cylinder was removed and the prep is still there. If you need the door to actually key, you want a functioning rim cylinder, not the 12E dummy.
2) Does the BEST 12E dummy rim cylinder come with the ring and spindle, or do I order those separately?
The hardware comes in the box: the cylinder, the RP3 ring package, the 1E-S2 spindle, a clamp plate and clamp plate screws. Nothing else is required to mount it. Optional extras exist if the application calls for them, including the 3E-04 dummy, the 3E-7A4 turn knob, the 3E-7B4 dust cover, and the A26139 adaptor ring used for 1E74 cylinder compatibility.
3) Can a BEST 12E dummy cylinder go into another manufacturer's rim prep?
Yes. The 12E is interchangeable with other manufacturers' rim cylinders, so it drops into a standard rim prep rather than needing BEST hardware around it. It is machined from solid bar stock brass or bronze. If the existing cylinder is a 1E74, use the A26139 adaptor ring.
4) What is the closest working rim cylinder if the BEST 12E dummy will not do the job?
The 12E dummy rim cylinder is non-functional - it fills the rim prep for visual consistency and does not operate anything. When the opening needs a rim cylinder that actually turns a device, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the Schlage Commercial 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and 2 keys. Pick the cam orientation your exit device or rim lock expects. The Corbin Russwin 3070 is another 6-pin rim cylinder housing, supplied with a 1-7/8 inch tailpiece.
5) The prep in my door is a mortise cylinder hole, not a rim prep - what should I order?
The 12E dummy is built for rim applications and will not thread into a mortise cylinder prep. For mortise openings, the Corbin Russwin 1000 is a Grade 1 mortise cylinder at 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 is a Grade 1 6-pin mortise housing at 1-1/4 inch length with an A01 cloverleaf cam. If the mortise lock is a Schlage L9000, the Corbin Russwin 1080 is a 1-1/2 inch 6-pin large format interchangeable core mortise cylinder cammed A01 for Schlage L. Confirm cam style and cylinder length against the lock case before ordering - they are not interchangeable with one another.
6) I need an interchangeable core rim cylinder, not a dummy - what takes a core?
The 12E dummy uses the BEST interchangeable core design but is a dummy and does not key into a working device. For a keyed rim cylinder built around a removable core, the Schlage Commercial 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys, so one part covers both cam orientations. The Schlage 20-057-C is the full size interchangeable core itself in C keyway, finished 643E aged bronze - the core that drops into an FSIC housing, not a complete rim cylinder on its own.
7) What is the equivalent part for an aluminum storefront door with an Adams Rite deadlock?
The 12E dummy is a rim cylinder and does not address a narrow stile deadlock prep. For Adams Rite MS1847 deadlock and deadlatch systems, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull that mounts with through-screws - so the choice comes down to how the stile is prepped. For a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 is the five pin tumbler cylinder pull built for that application. Where a mortise cylinder is what the narrow stile lock takes, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated down to a 1/2 inch minimum door thickness.
8) If I want the door to look keyed on both sides but only lock from one, what do I use?
The 12E dummy rim cylinder is exactly that part - a non-functional cylinder that fills the outside or inside rim prep so the opening reads consistent, machined from solid bar stock and supplied with the RP3 ring package, 1E-S2 spindle, clamp plate and screws. It comes in finishes from 605 bright brass and 626 satin chrome through 622 matte black and 690 statuary dark bronze, so it can be matched to the working hardware beside it. The keyed side of the same opening would take a functional cylinder such as the Schlage 20-021 rim cylinder with vertical tailpiece cam.
9) Which ring do I choose when ordering a BEST 12E cylinder?
Ring choice is an order decision and it depends on the prep you are dropping into. Five are offered: 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder, and tapered cylinder. Match the ring to the housing type and, for the mortise rings, to the pin count you specified for your door thickness. Getting this wrong is the usual reason a cylinder sits proud of the trim.
10) What finishes does the BEST 12E dummy cylinder come in, and can I match the rest of my hardware?
Ten finishes, by BHMA number: 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. Since the numbers are the standard BHMA codes, a property manager can read the number off the existing lever or exit trim and order the same one rather than eyeballing the color.
11) Can the BEST 12E be masterkeyed into our existing BEST system later?
It uses the BEST interchangeable core design and may be masterkeyed into any existing BEST system, so a facility running BEST small format cores can bring the opening into the keying system rather than leaving it as a one-off. That matters if the dummy is a placeholder today and the opening gets keyed in a later phase.
12) Is a Medeco rim cylinder a drop-in substitute for the BEST 12E dummy?
They serve different openings. The 12E dummy is a non-functional rim cylinder for rim prep. The Medeco rim cylinders in the same family are keyed lazy-motion cylinders matched to specific residential locksets: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Because each is cut to a particular lock's tailpiece, match the cylinder to the lock brand rather than to the rim prep alone.
13) My hardware is a key-in-knob or key-in-lever, not a rim device - what cylinder replaces that?
A rim cylinder like the 12E dummy will not fit a knob or lever cylinder pocket. Kaba Ilco covers that side: the 1539 is a key-in-knob and key-in-lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder made for Sargent hardware. For a deadbolt, the 1549 is the key-in-deadbolt cylinder. Falcon's A23161-05 G is a key-in-lever cylinder for RU and T series in a 6-pin G keyway, keyed different with 2 cut keys.
14) I need a keyed cylinder in a specific keyway to match the rest of the building - what are my options?
The 12E dummy is a blank-face part and may be masterkeyed into an existing BEST system only in the sense that it carries the BEST interchangeable core design; it does not operate. Where the keyway itself is the deciding factor, the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core in C keyway in 643E aged bronze. Both let you stay on an existing Schlage C system rather than introducing a second key.
15) Is the BEST 12E the right part for an Emtek handleset or an Arrow interconnected lock?
No - the 12E dummy is a rim cylinder for rim prep and does not carry a residential handleset tailpiece. For Emtek, the Emtek CY4 is the brand's own cylinder, and the Medeco 1065140 is a 5-pin retrofit cylinder that covers the Arrow JL interconnected lock plus the Emtek handleset and deadbolt outside cylinder. The Medeco 1065244 is the 5-pin rim lazy motion version with an Emtek tailpiece. Which one you want depends on whether you are replacing the whole cylinder or retrofitting a higher security core into the existing lock.
16) What diameter is the BEST 12E cylinder?
1-5/32 inches, with a 1-1/2 inch standard diameter specification, which is what lets it sit in a conventional rim prep alongside other manufacturers' cylinders. Confirm the hole in your door or trim before you cut anything new.
