BEST 12E72-S2RP626 – Frequently Asked Questions

1) Will the BEST 12E72 rim cylinder fit a standard rim exit device or rim night latch?
The 12E72 is a standard 1-1/8 inch rim cylinder, which is the conventional rim size rim exit devices and rim night latches are prepped for. It ships with the cylinder, RP3 ring package, 1E-S2 spindle, clamp plate and clamp plate screws, so you get the mounting parts along with it. The spindle is cut to length at install to suit your door and device thickness, standard practice on any rim cylinder.
2) Does the BEST 12E72 come with a core and keys, or do I need to order those separately?
The 12E72 is a housing built for a BEST small format interchangeable core, so the core is what carries the keying and it is specified separately. That is the point of the design: you buy the housing once, then drop in a 7-pin SFIC core keyed into whatever master key system the building already runs. If you have a BEST system in place, your existing core supplier keys the core to it and the housing takes it without any change.
3) Can I swap a BEST 12E72 in place of another brand's rim cylinder on my exit device?
Yes. BEST states the 12E72 is interchangeable with other manufacturers' rim cylinders, so it drops into a standard rim prep in place of a conventional rim cylinder. What changes is the key system: once it is in, the opening is keyed off a BEST SFIC core rather than the old conventional cylinder, so plan the retrofit as part of moving that door onto your BEST keying.
4) What is the difference between the BEST 12E72 SFIC rim cylinder and a conventional 6-pin rim cylinder like the Schlage 20-021?
Two different keying philosophies. The Schlage Commercial 20-021 is a conventional 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, so it is pinned as a fixed cylinder and rekeying means pulling it apart. The 12E72 is a housing for a BEST 7-pin small format interchangeable core: a control key pulls the core out and a new one goes in without taking the device apart. If you rekey often, or run a large master key system across many doors, the interchangeable core is what you want. For a one-off door with no key system behind it, the conventional cylinder is simpler.
5) I need a rim cylinder for a Schlage keyway interchangeable core system, not BEST. What should I use?
The 12E72 is built around the BEST small format interchangeable core and will not take a full size core. For a full size interchangeable core rim application, the Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with 2 keys, and the core itself is the Schlage 20-057-C full size interchangeable core in C keyway, 643E Aged Bronze. Small format and full size cores are not interchangeable with each other, so pick the family your building already runs.
6) Is the BEST 12E72 a rim cylinder or a mortise cylinder? I have a mortise lock.
Rim. The 12E72 mounts through the door from the back with a clamp plate and drives a device on the face of the door, which is how rim exit devices and rim latches are cylindered. A mortise lock takes a threaded mortise cylinder instead. For mortise work in this catalog, look at the Corbin Russwin 1000 Series Grade 1 mortise cylinder, 1-1/2 inch length with an A02 straight cam, or the 1070 Grade 1 housing at 1-1/4 inch, 6-pin, with an A01 cloverleaf cam. Ordering a rim cylinder for a mortise lock is one of the most common wrong-part returns.
7) What cylinder should be used on an aluminum storefront door instead of a BEST 12E72?
Narrow stile storefront usually runs an Adams Rite deadlock, which takes a cylinder matched to that lock rather than a standard rim cylinder. The Adams Rite 4036 is a five-pin mortise cylinder, Grade 1, in the 4036 series, with a 1/2 inch minimum door thickness. Where the pull itself carries the cylinder, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 five pin tumbler cylinder pull mounts with through-screws, both for the Adams Rite MS1847 deadlock and deadlatch. For a wood door on an Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matched part.
8) What is the closest equivalent to a BEST 12E72 rim cylinder if the key system is Schlage rather than BEST?
The Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and it is the closest counterpart when the building is keyed on a Schlage interchangeable core system. The difference to plan for is core format: the BEST 12E72 carries a small format interchangeable core in a 7-pin configuration, while the 20-057 takes a full size interchangeable core. The two core formats are not interchangeable in the same housing, so the housing and the core have to be ordered as a matched pair.
9) If a building does not run an interchangeable core program, what rim cylinder can be used in place of the BEST 12E72?
A conventional keyed rim cylinder covers the same opening without the core program overhead. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage Commercial 20-022 is the same cylinder with a horizontal tailpiece cam. Those are fixed-keyed cylinders, so rekeying means pulling and pinning the cylinder. The BEST 12E72 keeps its SFIC housing and interchangeable core, which lets a core be swapped out without disassembly - worth having when turnover across a property is frequent.
10) The opening needs a mortise cylinder, not a rim cylinder. What takes the place of the BEST 12E72?
A mortise lock body needs a threaded mortise cylinder with a cam, which is a different part entirely from a rim cylinder and spindle. For an interchangeable core program, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 cloverleaf cam. For conventional keying, the Corbin Russwin 1000 Grade 1 series mortise cylinder comes in 1-1/2 inch length with an A02 straight cam, and the 1070 Grade 1 series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Cam style has to match the lock body it is going into.
11) Will a Detex MC65 work where a BEST 12E72 is specified?
No - the Detex MC65 is a mortise cylinder with a Schlage C keyway in a 1-1/8 inch 6-pin configuration, and it threads into a mortise lock case. The BEST 12E72 is a rim cylinder that mounts through the door and drives a rim device with a spindle and clamp plate. Both are described as 1-1/8 inch, which is where the confusion usually starts, but on the 12E72 that is the standard rim cylinder size and on the MC65 it is mortise cylinder length. They do not swap.
12) What finishes does the BEST 12E72 rim cylinder come in, and can I match the rest of my hardware?
Ten finishes across the 12E72: 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. Those are standard BHMA finish numbers, so a 626 cylinder matches 626 exit device trim and 626 levers elsewhere in the building. Dark bronze openings usually take 613 or 690 depending on whether the existing hardware is oil-rubbed or statuary.
13) Why choose a 7-pin BEST cylinder over a 6-pin one?
The 12E72 uses a 7-pin core, and the extra chamber buys two things a facility cares about: a much larger pool of key combinations, so a master key system can grow across a campus without running out of changes, and more pin stack depth to work against picking. Most conventional commercial cylinders in this catalog are 6-pin, including the Corbin Russwin 3070 rim housing and the Detex MC65. If your BEST system is already 6-pin, keep the door on 6-pin cores; a 7-pin core will not work in a 6-pin system's keying.
14) I manage a portfolio and want one key system across all the buildings. Does the BEST 12E72 fold into an existing BEST master key system?
That is what it is for. The 12E72 takes a BEST interchangeable core, so it drops into any existing BEST master key system already running in the building. Your maintenance staff can pull and replace cores with a control key on tenant turnover instead of calling a locksmith to rekey, which is the practical reason large property portfolios standardize on interchangeable core in the first place.
15) Do I need to buy a spindle and mounting ring separately for the BEST 12E72?
No, the package covers the install. A 12E72 ships with the cylinder, the RP3 ring package, a 1E-S2 spindle, a clamp plate and the clamp plate screws. The only thing you specify on top is the BEST SFIC core and its keying, plus the finish you want from the ten offered.
16) I need a key-in-knob or key-in-lever replacement cylinder, not a rim cylinder. What is the equivalent?
Different cylinder format entirely. Knob and lever cylinders sit inside the lockset and the 12E72 will not substitute for one. In this catalog the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. For a deadbolt cylinder, the Kaba Ilco 1549 Series is the key-in-deadbolt version. Falcon's 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.
17) A residential-style deadbolt or handleset needs a rim cylinder. Is the BEST 12E72 the right one?
Not usually. Deadbolts and handlesets take a lazy motion rim cylinder with a tailpiece cut for that lock. The Medeco 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. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and Emtek supplies the CY4 cylinder as a parts item. The BEST 12E72 is a standard 1-1/8 inch commercial rim cylinder that ships with the 1E-S2 spindle for rim devices.
18) Is the Corbin Russwin 3070 a substitute for the BEST 12E72 rim cylinder?
The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece from the 3000 series, so it addresses the same rim application. It is a different key system and a different core arrangement from the BEST 12E72, which uses a 7-pin small format interchangeable core and drops into an existing BEST master key system. Tailpiece length also has to be checked against the exit device or rim lock being driven - the 12E72 ships with the 1E-S2 spindle, RP3 ring package, clamp plate and clamp plate screws.
19) What is the difference between the Schlage 20-057 and the 20-057-C when cross-referencing a BEST 12E72?
The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys - the housing side. The 20-057-C is a full size interchangeable core with a C keyway in 643E aged bronze - the core side. Ordering one when the job needs the other is a common miss. The BEST 12E72 differs on both counts: it is a rim cylinder with SFIC housing in a 7-pin configuration, and it accepts a small format core that keys into an existing BEST master key system. It is offered in finishes including 605 bright brass, 626 satin chrome and 690 statuary dark bronze.
20) Does the tailpiece cam orientation matter when picking a rim cylinder for an exit device?
It does, and it is the detail that decides whether a cylinder drives the device at all. Schlage splits it across two part numbers: the 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal tailpiece cam, while the 20-057 uses a convertible tailpiece cam. The BEST 12E72 comes with the 1E-S2 spindle along with the RP3 ring package, clamp plate and clamp plate screws, so the spindle is cut to the device on installation rather than chosen as a separate part number.
21) For standardizing a facility on one interchangeable core program, how do the BEST 12E72 and the Corbin Russwin 1080 compare?
They serve different lock types and different core formats. The BEST 12E72 is a rim cylinder with SFIC housing in a 7-pin configuration that integrates into an existing BEST master key system and allows core changes without disassembly. The Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with an A01 cloverleaf cam, in the Grade 1 series. A facility running rim exit devices and mortise locks side by side needs a housing for each lock type, keyed to whichever core program the site has adopted.
22) Is the BEST 12E72 solid metal or a cast housing? It is going on a high-traffic exterior door.
Machined from solid bar stock, not cast. That matters on an entry that gets hit constantly or is exposed to attack: a bar stock housing holds its dimensions and resists wrenching better than a cast body. Common placements are commercial office entries, schools, hospitals, retail, warehouses, multi-tenant residential and municipal buildings.
23) What exactly is the BEST 12E72, the cylinder body or the whole lock?
It is the rim cylinder assembly only, the part that accepts the key and turns the device. There is no latch, no bolt, no exit device in the box. You get the housing, ring package, spindle and clamp plate hardware; the lock or exit device it operates is a separate purchase, as is the BEST core that goes inside.
24) Is a Kaba Ilco 1549 a possible replacement for a BEST 12E72?
No. The Kaba Ilco 1549 series is a key-in-deadbolt cylinder and its listed function is deadbolt, so it is built to go into a deadbolt body. The BEST 12E72 is a standard 1-1/8 inch rim cylinder with SFIC housing that mounts through the door face with a spindle and clamp plate to operate a rim device. The names sound adjacent because both are cylinders, but the mounting and the drive are unrelated.
