BEST BES-3E74C4RP3626-PC – Frequently Asked Questions

1) What cam comes on the BEST 3E cylinder, and can I get one for an Adams Rite lock?
Standard supply is the 3E-C3 cam, which drops straight into BEST mortise lock mechanisms. If you are driving an Adams Rite MS deadlock instead, order the Adams Rite MS cam option rather than the standard cam. A standard spindle option is also offered. Pick the cam to match the lock body, not the door, because the wrong cam geometry will turn but will not throw the bolt.
2) I have 1E74 cylinders in the building already. Can I move to 3E without redrilling?
There is an adaptor ring, part A26139, that lets 1E74 cylinders fit 3E tapped holes. That is the piece that makes a phased changeover practical: you can upgrade openings to the 3E prep and keep existing 1E74 cylinders working in the meantime, rather than doing the whole building in one shot.
3) What do I have to specify when ordering a BEST 3E mortise cylinder?
Three things are required at order time on the 3E Premium Core cylinder: the keyway, a keymark, and a marking number. Keyway choices are WA, WB, WC, WD, WE, WG, WH, WK and WY. Beyond that you choose finish, the cam or spindle option, and the ring style. Property managers keying to an existing master should pull the keyway and keymark off a cylinder already in the building so the new ones fall into the same system.
4) Is this a 6-pin or 7-pin BEST cylinder, and what length is the housing?
This is the 7-pin configuration, 1-1/2 inch diameter with a 1-1/4 inch length for the 7-pin core. BEST cores are not cross-compatible between 6-pin and 7-pin depths, so if the rest of your system is 6-pin, order 6-pin housings instead. Ring choices include both 6-pin mortise and 7-pin mortise styles, so match the ring to the core depth you are running.
5) Can I use a rim cylinder instead of the BEST 3E mortise cylinder on an exit device?
No - a rim cylinder and a mortise cylinder are not interchangeable. The BEST 3E Series cylinder is a mortise cylinder threaded into a mortise lock body and supplied with the 3E-C3 cam. For a rim application, the Schlage 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; the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Rim cylinders drive a tailpiece through the door; mortise cylinders drive a cam inside the lock case.
6) What is the closest equivalent to a BEST 3E mortise cylinder if the mortise lock is a Corbin Russwin?
For a Corbin Russwin mortise lock, look at the Corbin Russwin 1000 Grade 1 series mortise cylinder in 1-1/2 inch length with an A02 straight cam. It occupies the same role as the BEST 3E Series premium core mortise cylinder, which ships with the 3E-C3 cam sized for BEST mortise lock mechanisms. The cam is the deciding detail: the 3E-C3 drives BEST mortise bodies, while the 1000 series is supplied with the A02 straight cam. If the existing lock is a Corbin Russwin body, match the cylinder to it rather than swapping in a BEST cam.
7) I need a mortise cylinder for a Schlage L9000 lock, not a BEST mortise body. What should I order?
The Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder is built for Schlage L9000 mortise locks and comes with the A01 Schlage L cam, in a 6-pin format. The BEST 3E Series premium core mortise cylinder is a 7-pin cylinder supplied with the 3E-C3 cam intended for BEST mortise lock mechanisms, so it is the wrong cam for an L9000 body. Choose by the lock body you are dropping into.
8) What should I use on an Adams Rite narrow stile aluminum door instead of the BEST 3E?
The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness, which suits narrow stile aluminum work. Note that the BEST 3E Series is also offered with an Adams Rite MS cam option alongside the standard cam, so if you are keying the opening into an existing BEST system you can stay with the 3E and specify the MS cam; if the opening stands alone, the 4036 is the straightforward Adams Rite-native choice.
9) Which ring style should I choose for a BEST 3E cylinder?
Five ring styles are offered: 3E Mortise, 6-pin Mortise, 7-pin Mortise, Rim Cylinder and Tapered Cylinder. The mortise rings match the core depth and the 3E tapped hole. Tapered is the choice where you want the collar to blend into a beveled or sculpted trim face. The ring sets how the cylinder face sits against the escutcheon, so it is a trim and thickness decision, not a security one.
10) What finishes does the BEST 3E mortise cylinder come in to match the rest of my hardware?
Ten BHMA finishes: 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. Match the BHMA number on your existing lever or escutcheon rather than the name, since 626 satin chrome and 619 satin nickel read similarly at a distance but do not match side by side.
11) Do I need a dummy cylinder, thumbturn or dust cover for some of my openings?
The 3E line covers those too. 3E-04 is the dummy, 3E-7A4 is the turn knob version, and 3E-7B4 is the dust cover. A dummy fills a cylinder hole on a door that does not need keyed access, the turn knob gives inside egress without a key, and the dust cover suits exterior or dirty environments where the keyway needs shielding.
12) What is the closest alternative to a BEST 3E mortise cylinder if I am not on a BEST keyway?
For conventional (non-interchangeable-core) mortise cylinders, the Corbin Russwin 1000 Grade 1 mortise cylinder at 1-1/2 inch length with an A02 straight cam is a direct-swap style alternative, and the Corbin Russwin 1070 Grade 1 housing at 1-1/4 inch, 6-pin, uses the A01 cloverleaf cam. If the opening is a Schlage L9000 mortise lock, the Corbin Russwin 1080 LFIC cylinder at 1-1/2 inch with the A01 Schlage L cam is built for that prep. The BEST 3E remains the choice when the building is already on BEST cores and keyways.
13) Is a 6-pin mortise cylinder a substitute for the BEST 3E 7-pin?
Not in the same key system. The BEST 3E Series premium core mortise cylinder is a 7-pin configuration with a 1-1/4 inch length for that pin stack. Six-pin mortise cylinders such as the Corbin Russwin 1070 Grade 1 series 1-1/4 inch 6-pin mortise housing with A01 cloverleaf cam, or the Detex MC65 in Schlage C keyway at 1-1/8 inch, use a different pin count and keyway family, so keys will not cross. Match pin count and keyway to the system already on the building.
14) On an Adams Rite MS1847 storefront deadlock, do I order the BEST 3E or a cylinder pull?
That depends on whether the stile needs a pull. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock and deadlatch systems, and the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock and deadlatch. For a wood door application Adams Rite lists the 4026 five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch. The BEST 3E Series is a mortise cylinder only, though it is offered with an Adams Rite MS cam for MS-style lock bodies where a separate pull is not wanted.
15) I need to rekey a knob or lever, not a mortise lock - what replaces the BEST 3E there?
A mortise cylinder will not fit a key-in-knob or key-in-lever chassis. For those, 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 Series is a key-in-knob replacement cylinder. Falcon also offers the A23161-05 G key-in-lever cylinder, a 6-pin G keyway supplied keyed different with two cut keys. The BEST 3E Series remains the choice when the housing is a mortise lock body taking a threaded cylinder and cam.
16) For a residential handleset or deadbolt, is the BEST 3E the right cylinder?
Only if the door carries a mortise lock body. For residential deadbolts and handlesets the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder. The BEST 3E Series is a 7-pin mortise cylinder with a cam, and it accommodates door thickness from 7/8 inch to 2-1/2 inch when there is a mortise case behind it.
17) What is the difference between the BEST 3E mortise cylinder and a Schlage FSIC cylinder like the 20-057?
The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is a full size interchangeable core cylinder in C keyway, 643E aged bronze. Those accept an FSIC core in Schlage keyways. The BEST 3E Series premium core mortise cylinder is a 7-pin mortise cylinder ordered in BEST keyways WA through WY with a keymark and marking number specified, and is finished in options including 626 satin chrome and 613 satin bronze oil-rubbed. The core format and keyway family are what separate them.
18) What is this cylinder made of, and will it hold up on an exterior door?
Solid brass or bronze throughout. Both resist corrosion well, which is why the 3E is used on exterior commercial openings as well as interior ones. If the door is exposed to weather or wash-down, pair it with the 3E-7B4 dust cover to keep grit out of the keyway.
19) Is there installation documentation for the BEST E Series cylinders?
Yes, the E Series Service Manual covers the line and is the reference for cam selection, ring stacking against door thickness, and core installation. Worth reading before you order if you are specifying ring packages across a mix of door thicknesses.
20) I have a key-in-deadbolt cylinder to replace. Is the BEST 3E the right part?
No. For a key-in-deadbolt housing the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function, and the 1539 Series covers key-in-knob and lever universal applications. The BEST 3E Series premium core mortise cylinder threads into a mortise lock case and drives a cam, and it is supplied with the RP4 ring package containing 3E-R2 at 1/8 inch and 3E-R4 at 1/4 inch to set cylinder projection in that case.
