BEST BES-1EB6B4-C4RP3626-SC – Frequently Asked Questions

1) What length is the BEST 1EB mortise cylinder in 6-pin versus 7-pin?
The 1EB Series mortise cylinder runs 1-1/8 inches long in the 6-pin version and 1-9/32 inches in the 7-pin. Both use the same 1-5/32 inch cylinder diameter, so the difference is purely how deep the housing sits in the lock case. Match the pin count to the rest of your BEST system, since a 7-pin key will not operate a 6-pin cylinder.
2) Which cam comes on the BEST 1EB cylinder, and can I get an Adams Rite cam instead?
Standard build is the 1E-C4 cam for BEST 1E series mortise locks. If you are driving an Adams Rite MS deadlock, order the Adams Rite MS cam option instead. A standard spindle is also offered where the application calls for a spindle rather than a cam. Pick that on the Options axis when you order, because the cam is what actually throws the bolt.
3) Which ring package do I need for a BEST 1EB mortise cylinder?
For mortise work, RP2 is the ring package for the 6-pin cylinder and RP3 for the 7-pin. The ring selection also covers 3E mortise, rim cylinder and tapered cylinder configurations, so the ring you choose has to match both the pin count and the housing style you are installing. Rings take up the gap between the lock face and the door, so getting this wrong leaves the cylinder proud or buried.
4) I need a cylinder for an Adams Rite storefront deadlock. Is this the right one?
It can be, if you order the 1EB with the Adams Rite MS cam option, which is the driver those deadlocks need. If you would rather use an Adams Rite part, the 4036 mortise cylinder is a five-pin Grade 1 cylinder that works down to a 1/2 inch minimum door thickness, which matters on thin aluminum stiles. For an MS1847 deadlock where you also want a pull, the Adams Rite 4024 cylinder pull with trim plate or the 4025 five pin cylinder pull with through-screws combine both.
5) What do I have to specify when ordering a BEST 1EB cylinder?
Four things: pin count (6 or 7), the ring package (3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder or tapered cylinder), the cam or spindle option (standard cam, Adams Rite MS cam, or standard spindle), and the finish. BEST's own order procedure has you designate B4 at step C for this cylinder. Getting the ring and cam right matters more than anything else, since those two decide whether the cylinder sits flush and actually throws the lock.
6) Is there an interchangeable core option instead of the BEST 1EB standard core cylinder?
The BEST 1EB Series is a standard core mortise cylinder. If the keying program runs on full size interchangeable cores, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish. The Corbin Russwin 1080 is a 1-1/2 inch LFIC 6-pin mortise cylinder for Schlage L9000 mortise locks with an A01 cloverleaf cam if you need a small format core in a mortise case.
7) What is the closest alternative to a BEST 1EB mortise cylinder if the opening uses a conventional keyed cylinder instead of a removable core?
The BEST 1EB Series is a standard core mortise cylinder built around the 1E-C4 cam with RP2 and RP3 ring packages for 6-pin and 7-pin mortise prep. If the opening calls for a conventional mortise cylinder rather than a BEST core, the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam covers a mortise lock body the same way, and the Corbin Russwin 1070 Grade 1 6-pin mortise housing at 1-1/4 inch uses an A01 cloverleaf cam. Match the cam to the lock body you are feeding, since the 1E-C4 cam and the A01/A02 cams are not interchangeable.
8) What finishes does the BEST 1EB mortise cylinder come in to match my existing trim?
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 property managers standardizing a building, 626 satin chrome and 613 oil-rubbed bronze are the two that most commonly match existing commercial lever trim. The housing itself is solid brass or bronze underneath the plating.
9) I need a rim cylinder, not a mortise cylinder. Does the 1EB cover that?
The 1EB is a mortise cylinder at heart, though a rim cylinder ring option is offered. A mortise cylinder threads into the lock body and turns a cam; a rim cylinder mounts through the door and drives a tailpiece into a surface-mounted device such as an exit device or a rim deadlock. If you are feeding an exit device, look at a dedicated rim cylinder: the Schlage 20-021 has a vertical tailpiece cam and the 20-022 a horizontal one, and the Corbin Russwin 3070 is a 6-pin rim housing with a 1-7/8 inch tailpiece.
10) What looks like a substitute for the 1EB mortise cylinder but will not fit a mortise lock body?
Several cylinders in the same size family are not mortise-threaded. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder for Sargent - all of those drop into knob or lever chassis, not a mortise case. The Kaba Ilco 1549 is a key-in-deadbolt cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway. The BEST 1EB is a mortise cylinder with the 1E-C4 cam and 1-5/32 inch diameter, so it goes into a mortise lock case.
11) If the mortise lock is keyed to a Schlage C keyway rather than a BEST system, what mortise cylinder should I use?
The BEST 1EB Series is built for BEST 1E series mortise lock mechanisms with the 1E-C4 cam. For a Schlage C keyway mortise cylinder, the Detex MC65 is a commercial grade 6-pin mortise cylinder in Schlage C keyway at 1-1/8 inch length, which matches the same 1-1/8 inch length the 1EB uses in its 6-pin configuration.
12) What is the alternative to a 1EB cylinder for a residential handleset or deadbolt retrofit?
The BEST 1EB Series is a commercial-style mortise cylinder for 1E series mortise locks. For residential handleset and deadbolt retrofits, 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 lazy motion rim cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the Emtek CY4 cylinder is sold each.
13) Does the BEST 1EB mortise cylinder include a dust cover?
Yes, a dust cover is integrated to keep debris and moisture out of the plug. That is worth having on exterior openings and in industrial or warehouse settings where airborne dust will otherwise work its way into the pin chambers.
14) Is there installation documentation for the BEST 1EB cylinder?
The E Series Service Manual covers this cylinder and is published as a PDF alongside the product. It is the reference for cam and ring assembly as well as pinning. For the lock itself, the parent device instructions govern, since the cylinder only threads into a lock case that is already prepped.
15) For a wood door deadlock, is the BEST 1EB the right cylinder?
The BEST 1EB Series is a mortise cylinder for BEST 1E series mortise lock mechanisms, supplied with the 1E-C4 cam. For a wood door narrow deadlock application, the Adams Rite 4026 is a five-pin cylinder pull made for the Adams Rite 5017 wood door deadlock and deadlatch, which is a pull and cylinder in one piece rather than a bare mortise cylinder.
