BEST BES-1EB6B2-C4RP3626-SC – Frequently Asked Questions

1) Will a BEST 1EB rim cylinder accept my existing BEST interchangeable core?
The 1EB Series is a standard core rim cylinder, so it takes a BEST standard (small format) interchangeable core, not a full size core. You pick 6-pin or 7-pin to match the cores already in your building. Keyway has to match too, and the 1EB is offered in A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD and TE. If your facility is standardized on, say, C keyway 7-pin, order the 7-pin in C and the core you already carry drops in.
2) What is the difference between the 6-pin and 7-pin BEST 1EB cylinder, and which one do I order?
Length is the difference. The 6-pin runs 1-1/8 inches with a 1-3/16 inch rim dimension; the 7-pin runs 1-9/32 inches with a 1-11/32 inch rim dimension. Both are 1-5/32 inches in diameter. Order to match the core system already in the building, since a 7-pin core will not work in a 6-pin housing. The ring package follows the choice as well: RP2 for mortise 6-pin, RP3 for mortise 7-pin and for all rim configurations.
3) Which cam comes on the BEST 1EB cylinder and can I get an Adams Rite cam instead?
Standard build carries the 1E-C4 cam, which is what mates with BEST 1E series rim lock mechanisms. If you are driving an Adams Rite MS deadlock, the 1EB is also configurable with an Adams Rite MS cam, and a standard spindle is offered as a third option. Pick the cam by what the lock body needs, not by the door, because the wrong cam throw is the most common reason a swapped cylinder turns but does not retract anything.
4) What do I have to specify when ordering a BEST 1EB rim cylinder?
Four things beyond finish. Keyway (A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD or TE), keymark, marking number, and pin count (6 or 7). On top of that you choose the ring and the cam or spindle option. Keymark and marking number are how BEST ties the cylinder into an existing masterkey system, so a facility with a key schedule should pull those off the schedule rather than guess.
5) I need a mortise cylinder, not a rim cylinder - what are the alternatives to a BEST 1EB?
The BEST 1EB Series covers both sides of that line: its ring options include 6-pin Mortise, 7-pin Mortise, 3E Mortise, Rim Cylinder and Tapered Cylinder, with RP2 rings standard for the mortise 6-pin and RP3 for mortise 7-pin and all rim configurations. If the lock body calls for a different manufacturer's mortise cylinder, the Corbin Russwin 1000 is a Grade 1 mortise cylinder in 1-1/2" length with an A02 straight cam, the Corbin Russwin 1070 is a Grade 1 1-1/4" 6-pin mortise housing with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8" 6-pin mortise cylinder in Schlage C keyway. The cylinder length and cam shape have to match the lock case and the hub it drives, which is what separates these three from each other.
6) What do I use instead of a BEST 1EB when the cylinder has to go into an aluminum storefront deadlock?
The BEST 1EB Series does offer an Adams Rite MS cam as a cam option, which is what allows a BEST core to drive an Adams Rite MS deadlock. When the opening needs the Adams Rite cylinder itself, the peers are the 4036 mortise cylinder with five-pin security, a Grade 1 cylinder rated to a 1/2" minimum door thickness, and the cylinder pulls: the 4024 with trim plate mounting and the 4025 with through-screws, both for the Adams Rite MS1847 deadlock or deadlatch. Choose by what the stile is prepped for - a mortise cylinder hole takes the 4036, while a pull prep takes the 4024 or 4025.
7) What is the cross-brand equivalent of a BEST 1EB rim cylinder for a 6-pin rim application?
The BEST 1EB Series is a 1-5/32" diameter rim cylinder in a 6-pin (1-1/8" length, 1-3/16" rim) or 7-pin (1-9/32" length, 1-11/32" rim) configuration. Two direct cross-brand peers exist in 6-pin rim form: the Schlage Commercial 20-021 rim cylinder, 6-pin with a vertical tailpiece cam, and the Schlage Commercial 20-022, the same 6-pin rim cylinder with a horizontal tailpiece cam. The Corbin Russwin 3070 is also a 6-pin rim cylinder housing, supplied with a 1-7/8" tailpiece. The BEST 1EB ships with a 1E-C4 cam for BEST 1E series rim lock mechanisms, so the deciding factor between them is the cam or tailpiece the existing exit device or rim lock is prepped to accept, not the cylinder body itself.
8) Which rim cylinder should I order when the tailpiece orientation on the exit device is not known yet?
The BEST 1EB Series is supplied with a standard 1E-C4 cam matched to BEST 1E series rim locks, and the Schlage rim cylinders are split by cam direction: the 20-021 uses a vertical tailpiece cam and the 20-022 uses a horizontal tailpiece cam. When the prep is unconfirmed, the Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, which lets the cam be set at install rather than at order. Note the difference in core type: the 20-057 takes a full size interchangeable core, while the 1EB is built for a BEST standard core, so the two are not keyed or cored the same way.
9) Will a BEST 1EB cylinder work in a Schlage L9000 mortise lock?
The BEST 1EB Series is built around the 1E-C4 cam for BEST 1E series lock systems, so it is specified against BEST hardware rather than a Schlage lock case. For a Schlage L9000 mortise lock the Corbin Russwin 1080 is the cylinder written for that application: a Grade 1 series 1-1/2" LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks, with the A01 Schlage L cam. That cylinder takes a large format interchangeable core, which is a different core platform from the BEST standard core the 1EB is prepped for, so the two are not interchangeable in the same keying system.
10) Which cylinder matches an existing keyway when the building is already keyed to Schlage C?
The BEST 1EB Series is ordered in BEST keyways - A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD and TE - which are BEST's own keyway designations and not the Schlage C keyway. Where the site is already keyed Schlage C, the Detex MC65 is a 1-1/8" 6-pin mortise cylinder supplied in Schlage C keyway, and the Schlage Commercial 20-057-C is a full size interchangeable core in C keyway. Matching the existing keyway is what keeps one key working across the doors, so the keyway family drives this choice before length or finish does.
11) What else could I use instead of a BEST 1EB rim cylinder if I am not on a BEST key system?
If the building is not keyed BEST, the interchangeable core is no advantage. Schlage's 20-021 rim cylinder is a 6-pin with a vertical tailpiece cam and the 20-022 is the same in horizontal, so match whichever tailpiece your rim device wants. Corbin Russwin's 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. If you do want an interchangeable core but on Schlage's system, the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, which is a full size core rather than the small format core the 1EB takes.
12) I am standardizing a whole building on one key system. Does the BEST 1EB let me rekey without pulling cylinders?
That is the point of a standard core cylinder. Once the 1EB housings are installed, a control key pulls the core out and a new core goes in, so a tenant turnover or a lost master does not mean taking the cylinder out of the door. Match all the housings to one pin count, 6 or 7, and one keyway across the property so a single core stock covers every opening. Keymark and marking number are specified per order to tie each cylinder into that system.
13) What is a 1-5/32 inch cylinder diameter and will it fit my existing cylinder hole?
1-5/32 inches is the standard rim and mortise cylinder body diameter used across commercial door hardware, so a 1EB goes into a prep already carrying a conventional rim cylinder. What varies is the projection through the door, and that is set by the ring package, RP2 for mortise 6-pin and RP3 for mortise 7-pin and all rim configurations. Measure your door thickness and specify the ring accordingly rather than assuming the collar on the old cylinder transfers.
14) Is a key-in-knob or key-in-lever cylinder a substitute for a BEST 1EB rim cylinder?
No - those sit in a different part of the lock. The BEST 1EB Series is a rim and mortise cylinder platform with RP2 and RP3 ring packages and a 1E-C4 cam that drives a separate lock mechanism. A key-in-knob or key-in-lever cylinder drops into the knob or lever itself: 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 in a 6-pin G keyway, keyed different with two cut keys. If the existing hardware is a rim exit device or a mortise lock case, none of those will mount.
15) Can I use a BEST 1EB rim cylinder on a residential deadbolt or handleset?
The BEST 1EB Series is a commercial rim and mortise cylinder with the 1E-C4 cam for BEST 1E series lock systems, and it is not built to drive a residential deadbolt tailpiece. For those openings the peers are purpose-built: 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, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. The Kaba Ilco 1549 key-in-deadbolt cylinder and 1579 are also deadbolt function cylinders, and the Emtek CY4 is a cylinder sold each. The lazy motion mechanism in the Medeco units is what suits them to deadbolt hardware.
16) What is the difference between a standard core cylinder like the BEST 1EB and an interchangeable core cylinder?
The BEST 1EB Series is a standard core cylinder ordered by keyway (A through R plus TB, TC, TD and TE), keymark and marking number, in 6-pin or 7-pin, so the pinning is set to the keying system when the cylinder is built. An interchangeable core cylinder instead accepts a removable core that can be swapped in the field: the Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is a full size interchangeable core in C keyway with a 643E aged bronze finish. Where a facility wants to rekey by pulling cores rather than repinning cylinders, that is the difference that decides it.
17) For a wood door deadlock, what cylinder hardware should I specify?
The BEST 1EB Series is a cylinder for BEST 1E series rim and mortise lock mechanisms, with solid brass or bronze construction in finishes from 605 bright brass through 690 statuary dark bronze. For a wood door deadlock or deadlatch specifically, the Adams Rite 4026 is a five pin tumbler cylinder pull built for the Adams Rite 5017 wood door deadlock and deadlatch, while the 4024 and 4025 cylinder pulls are for the MS1847 deadlock and deadlatch. The pull is a combined cylinder and pull handle, so it is a different prep from a rim cylinder that sits behind an exit device.
18) Which of these cylinders carry a Grade 1 rating for an institutional spec?
Among the cross-brand peers, the Adams Rite 4036 mortise cylinder with five-pin security is a Grade 1 cylinder with a 1/2" minimum door thickness. The Corbin Russwin 1000 in 1-1/2" length with A02 straight cam, the 1070 1-1/4" 6-pin mortise housing with A01 cloverleaf cam, and the 1080 1-1/2" LFIC 6-pin mortise cylinder for Schlage L9000 are all Grade 1 series cylinders. The BEST 1EB Series is specified instead by core and cam compatibility - 6-pin or 7-pin standard core with the 1E-C4 cam for BEST 1E series lock systems - so on an institutional job the deciding question is whether the drawing calls out a grade or a keying platform.
19) What finishes does the BEST 1EB 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. For a fleet of openings already running 626, order 626 across the batch and the cylinder faces will read the same as the lever and exit trim.
20) Is a dust cover included with the BEST 1EB rim cylinder?
Yes, the dust cover ships with the cylinder. It keeps grit out of the keyway on exterior doors, loading docks and any opening exposed to weather or airborne debris, which is where a rim cylinder normally starts to feel gritty first.
21) Is the BEST 1EB cylinder solid brass, and will it hold up on an exterior door?
Construction is solid brass or bronze, which is what gives it corrosion resistance on exposed openings. Paired with the dust cover, that is the combination you want on an exterior or dock door. Finish choice matters for outdoor life as well: 613 satin bronze oil-rubbed and 690 statuary dark bronze are the living and dark finishes in the range, while 626 satin chrome is the usual commercial default.
