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

1) What is the difference between the 6-pin and 7-pin BEST 1EB rim cylinder?
Pin count changes the cylinder length. The 6-pin 1EB measures 1-1/8 inches long with a 1-3/16 inch rim dimension; the 7-pin runs 1-9/32 inches long with a 1-11/32 inch rim dimension. Both share the 1-5/32 inch diameter. Match the pin count to the rest of your BEST keying system, since a 7-pin core will not operate in a 6-pin housing.
2) Which cam comes with the BEST 1EB rim cylinder, and can I get an Adams Rite cam instead?
Unless you specify otherwise, the 1EB ships with the 1E-C4 cam for 1E series integration. On the order you can choose Standard Cam, Standard Spindle, or an Adams Rite MS Cam, so if you are driving an Adams Rite MS deadlock you pick the MS cam option rather than buying a separate adapter.
3) What ring package do I need to order with a BEST 1EB cylinder?
Rings are part of the order. Standard packages are RP2 for the 6-pin mortise and RP3 for the 7-pin mortise and all rim configurations. The ring choices you select from are 3E Mortise, 6-pin Mortise, 7-pin Mortise, Rim Cylinder, and Tapered Cylinder, so pick the ring that matches the application the cylinder is going into, not just the pin count.
4) How do I write out a BEST 1EB cylinder order correctly?
BEST uses a strung-together designation: series, pin/core type, cam, ring package, finish. The example given is 1EB 7B4 C4 RP3 626. On top of that you supply the keyway (WA, WB, WC, WD, WE, WG, WH, WK or WY), the keymark, and the marking number, all of which are required when ordering.
5) Will a BEST 1EB cylinder key into my existing BEST master key system?
Yes, provided you order it in the right keyway and keymark. The 1EB is offered in nine BEST keyways (WA, WB, WC, WD, WE, WG, WH, WK, WY), and keymark and marking number are required entries on the order so the cylinder is cut to your existing system rather than keyed at random.
6) What are the alternatives if I am not on a BEST keyway?
If the building is not keyed to BEST, go with a cylinder in the system you already run. Schlage Commercial offers the 20-021 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, both supplied with two keys. Corbin Russwin has the 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. For an interchangeable core setup outside BEST, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
7) I am rekeying knobs and levers, not exit devices — is the BEST 1EB the wrong cylinder?
Yes, a rim cylinder will not fit a 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 1549 is a key-in-deadbolt cylinder. Falcon also offers the A23161-05 G key in lever cylinder, a 6-pin G keyway unit keyed different with two cut keys. The BEST 1EB is a rim cylinder for 1E series rim lock systems.
8) What is a comparable rim cylinder to the BEST 1EB if the exit device uses a Schlage keyway?
The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The BEST 1EB rim cylinder is ordered in BEST keyways (WA through WY) with a 1E-C4 standard cam and can also be supplied with an Adams Rite MS cam, so the cam orientation you need on the Schlage side is chosen by part number rather than by option.
9) I need an interchangeable core rim cylinder instead of a keyed premium core — what should I look at?
The Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is the full size interchangeable core itself in the C keyway, 643E Aged Bronze. The BEST 1EB is supplied as a premium core rim cylinder with dust cover, keyed to a BEST keyway and marking number you specify at order.
10) What do I order if the opening needs a mortise cylinder rather than a rim cylinder?
A rim cylinder mounts through the door and drives a cam or tailpiece on the inside face, so it is not a mortise substitute. For mortise work the Corbin Russwin 1000 Grade 1 mortise cylinder comes 1-1/2 inch long with an A02 straight cam, the 1070 Grade 1 housing is 1-1/4 inch 6-pin with an A01 cloverleaf cam, and the Adams Rite 4036 mortise cylinder is a five-pin Grade 1 unit for stiles from 1/2 inch minimum. The BEST 1EB does include mortise ring packages in its ring selection, so specify rings to match the cylinder type you are actually installing.
11) What finishes does the BEST 1EB rim cylinder come in for matching other hardware in a building?
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 standard commercial opening 626 satin chrome is the usual match, and it is the finish shown in BEST's own ordering example.
12) Is the BEST 1EB cylinder a full replacement part for an existing rim lock?
It is a replacement cylinder for compatible BEST 1E series rim lock systems, built from solid brass or bronze with a dust cover included to keep contamination out of the plug. It is not a complete lock, so the device itself, the strike, and any trim stay as they are. Check the cam and ring against the parent device instructions before you pull the old cylinder.
13) What is a rim cylinder versus a mortise cylinder, and which do I need?
A rim cylinder mounts through the door and drives a tailpiece or spindle into a surface-mounted lock, typically a rim exit device or a rim-mounted deadlock. A mortise cylinder threads into the lock body itself and turns a cam. The 1EB covers both worlds through its ring and cam selection: rim ring packages for rim applications, 6-pin and 7-pin mortise rings plus 3E mortise for mortise work. Pick based on how the existing lock case is mounted.
14) Is the Corbin Russwin 3070 rim housing a substitute for the BEST 1EB rim cylinder?
Both are rim cylinders, but they are not interchangeable. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece in the 3000 series. The BEST 1EB is a 1-5/32 inch diameter premium core rim cylinder built for BEST 1E series rim applications, offered in 6-pin at 1-1/8 inch length and 7-pin at 1-9/32 inch length. Match the housing to the key system and tailpiece the exit device expects.
15) Which cylinders look like rim cylinders but are actually retrofit parts for residential handlesets and deadbolts?
Several Medeco parts carry rim-type bodies but are built for specific residential locks: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. The BEST 1EB is a 1-5/32 inch diameter rim cylinder for BEST 1E series rim lock systems.
16) Our exit devices are keyed to Schlage C — do we have to switch to BEST keyways?
No. The BEST 1EB rim cylinder is specified in BEST keyways WA through WY with a keymark and marking number given at order. If the building stays on Schlage C, the Detex MC65 mortise cylinder comes in Schlage C keyway as a 1-1/8 inch 6-pin unit for mortise prep, and the Schlage 20-057-C full size interchangeable core is furnished in the C keyway.
17) Which cylinder should I use for a Schlage L9000 mortise lock, and can the BEST 1EB cover it?
For a Schlage L9000 mortise lock, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, with the A01 cloverleaf cam for Schlage L. The BEST 1EB is a rim cylinder at 1-5/32 inch diameter and ships with the 1E-C4 cam for 1E series rim applications, so it is not the part for an L9000 mortise prep.
18) Is there service documentation for BEST E Series cylinders?
Yes. BEST publishes an E Series Service Manual covering the cylinder family the 1EB belongs to, and it is the reference for core removal, cam changes, and ring package fitment. Use it alongside the installation instructions for whatever rim device the cylinder is going into.
19) Can I get a single replacement cylinder for an Emtek lock, or does the BEST 1EB work there?
Emtek offers the CY4 cylinder sold each as a parts item, and Medeco's 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. The BEST 1EB is a premium core rim cylinder for BEST 1E series rim lock systems, keyed to a BEST keyway, so it is not a drop-in for Emtek trim.
