BEST 1EB6B2-C4RP3626-LC – Frequently Asked Questions

1) Does the BEST 1EB rim cylinder come with a core and keys?
No. The 1EB Series rim cylinder ships less core, so it's the housing only. You supply the BEST interchangeable core and keys to match your existing keying, which is the point of ordering it this way on a masterkeyed system. A dust cover is included to keep debris out of the housing before the core goes in.
2) What is the difference between the 6-pin and 7-pin BEST 1EB cylinder, and how do I know which one I need?
It's the core length. The 6-pin housing is 1-1/8 inches and the 7-pin is 1-9/32 inches. Match it to the cores already in your building: a 7-pin core will not seat in a 6-pin housing, and a 6-pin core in a 7-pin housing leaves the wrong depth. If you're standardizing a facility on one keying system, order the type that matches your existing BEST cores.
3) Which ring package do I order with a BEST 1EB cylinder?
Rings are a selection you make on the order. The choices are Rim Cylinder, 6-pin Mortise, 7-pin Mortise, 3E Mortise, and Tapered Cylinder. For rim applications the RP3 ring package applies; RP2 covers mortise 6-pin and RP3 covers mortise 7-pin. Pick the ring that matches the prep you're installing into, not just the pin count.
4) Can I use the BEST 1EB cylinder on an Adams Rite narrow stile deadlock?
Yes, if you order it with the Adams Rite MS cam. Cam is a selectable option: Adams Rite MS Cam, Standard Cam, or Standard Spindle. The standard cam is the 1E-C4, which works with 1E series lock mechanisms. Choose the MS cam only when the cylinder is driving an Adams Rite MS deadlock.
5) I don't run BEST interchangeable cores. What rim cylinder should I buy instead?
The 1EB only makes sense if you're on BEST small format interchangeable core keying, since it ships without a core. For a conventional keyed rim cylinder, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same with a horizontal tailpiece cam. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. If you want full size interchangeable core instead of BEST SFIC, the Schlage 20-057 is an FSIC rim cylinder with a convertible tailpiece cam.
6) What is the difference between the BEST 1EB rim cylinder less core and a Schlage 20-057 rim cylinder?
Both are rim cylinders supplied without a core, so the core is added separately to match an existing keying system. The BEST 1EB is a 1-5/32 inch diameter rim cylinder built for BEST E Series lock systems, offered in 6-pin and 7-pin types with a dust cover and ring package. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Choose by which core family the building is keyed to: BEST E Series cores go in the 1EB, Schlage FSIC cores go in the 20-057.
7) I need a keyed rim cylinder that arrives complete with keys, not a housing waiting on a core. What should I order?
The BEST 1EB is supplied less core, so it needs a separately keyed E Series core before it will operate. If you want a rim cylinder that ships ready to key, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and two keys. Pick the tailpiece orientation that matches the exit device or rim lock you are feeding.
8) Is the Corbin Russwin 3070 rim cylinder housing a drop-in replacement for a BEST 1EB?
They are not interchangeable as a unit. Both are rim cylinder housings sold without a core, but the Corbin Russwin 3070 is a 6-pin housing with a 1-7/8 inch tailpiece in the 3000 series and takes Corbin Russwin cores, while the BEST 1EB is a 1-5/32 inch diameter housing for BEST E Series cores and is offered in 6-pin and 7-pin. If the facility is keyed on BEST E Series, stay with the 1EB.
9) I am putting a keyed cylinder into an Adams Rite MS deadlock. Does the BEST 1EB cover that?
The BEST 1EB is offered with an Adams Rite MS cam option, which is the configuration used with Adams Rite MS deadlock hardware, and still accepts a BEST E Series core. If instead you need a cylinder pull rather than a plain cylinder, the Adams Rite 4024 mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin cylinder pull for the 5017 wood door deadlock and deadlatch.
10) Our building is keyed on Schlage C. Is the BEST 1EB the right cylinder, or should I look elsewhere?
The BEST 1EB takes a BEST E Series core, so it will not accept a Schlage C keyed plug directly. For a Schlage C keyway opening, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway in 643E aged bronze. Use the 1EB when the master key system is BEST.
11) What diameter is the BEST 1EB cylinder, and will it drop into a standard rim prep?
The housing is 1-5/32 inches in diameter, which is the standard BEST rim cylinder size for rim lock applications. Confirm your existing hole and backplate are cut for that diameter before swapping.
12) The opening takes a mortise cylinder, not a rim cylinder. What do I use instead of the BEST 1EB?
The 1EB is configured for rim applications as well as mortise ring options, but if the lock body is a true mortise case you may prefer a dedicated mortise cylinder. The Corbin Russwin 1000 Grade 1 mortise cylinder is 1-1/2 inch long with an A02 straight cam, and the Corbin Russwin 1070 Grade 1 housing is 1-1/4 inch, 6-pin, with an A01 cloverleaf cam. The Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 for doors 1/2 inch minimum thickness. Match the cam shape to the lock case before ordering.
13) Can I use a BEST 1EB cylinder to rekey a knob or lever lockset?
No. The 1EB is a rim cylinder body for BEST E Series rim and mortise applications and does not fit key-in-knob or key-in-lever chassis. For those, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key in lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys. For a key-in-deadbolt, the Kaba Ilco 1549 covers that.
14) What should I use instead of a BEST 1EB on a residential handleset or deadbolt?
The 1EB is built around BEST E Series cores and rim or mortise ring packages, which is a commercial keying system. For residential handlesets and deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. Emtek trim also takes the Emtek CY4 cylinder.
15) I need an interchangeable core cylinder that fits Schlage L9000 mortise locks. Does the BEST 1EB work there?
No. The 1EB is a BEST E Series rim cylinder body with 1-5/32 inch diameter and standard 1E-C4 cam, intended for 1E series lock mechanisms. For Schlage L9000 mortise locks, the Corbin Russwin 1080 is a Grade 1 1-1/2 inch LFIC mortise cylinder, 6-pin, with an A01 Schlage L cam specified for L9000 mortise locks.
16) What finishes does the BEST 1EB rim cylinder come in for matching existing door hardware?
Ten 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. If you're matching a run of doors, order by the BHMA number rather than the finish name.
17) What is the 1EB cylinder made of, and will it hold up on an exterior door?
Solid brass or bronze construction, which gives it corrosion resistance for exterior and high-traffic openings. The included dust cover keeps contamination out of the housing internals.
18) Which cylinder should I order to retrofit an Arrow JL interconnected lock rather than a BEST E Series opening?
The BEST 1EB is matched to BEST E Series rim and mortise hardware. For an Arrow JL interconnected lock, the Medeco 1065140 is a 5-pin retrofit cylinder for that lock and also serves as the outside cylinder on Emtek handlesets and deadbolts. Use the 1EB only where the opening is set up for a BEST E Series core.
19) Where do I find installation instructions for the BEST 1EB cylinder?
BEST publishes an E Series Service Manual that covers these cylinders. Beyond that, the cylinder is a component, so the lock or exit device it goes into has its own installation instructions that govern cam orientation and tailpiece length.
