BEST BES-12E62-C4RP3626-SC – Frequently Asked Questions

1) Will a BEST 12E rim cylinder work on a door where the existing rim cylinder is another brand?
Yes. The 12E Series rim cylinder is interchangeable with other manufacturers' rim cylinders, so it drops into rim device applications built for a standard rim cylinder. It measures 1-5/32 inches in diameter, which is the standard rim cylinder diameter, and ships with the RP3 ring package so you can shim the cylinder out to the right depth for your door face. Check the cam on the device you are replacing, since the 12E is ordered with either a standard cam or an Adams Rite MS cam.
2) What do I have to specify when ordering a BEST 12E rim cylinder?
Four things decide the part number. Keyway (A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD or TE), pin count (6-pin or 7-pin), finish, and the cam or spindle option (standard cam, Adams Rite MS cam, or standard spindle). You also give a keymark and a marking number so the core is cut to your system. Rings are ordered to suit the prep: rim cylinder, tapered cylinder, 3E mortise, 6-pin mortise or 7-pin mortise.
3) Can a BEST 12E cylinder be keyed into the BEST masterkey system already running in my building?
That is what it is built for. The 12E takes a BEST interchangeable core and may be masterkeyed into any existing BEST system, so a property manager standardizing a building can put rim devices on the same master as the mortise and cylindrical locks already keyed. Order it in the keyway your system uses and give your keymark and marking number so the core matches.
4) Can I use a BEST 12E cylinder on an Adams Rite MS deadlock in an aluminum storefront door?
Yes, if you order it with the Adams Rite MS cam. That cam option is what drives an MS-series deadlock, and without it the standard cam will not throw the bolt. Glass front installers replacing a cylinder on an MS lock should specify that option up front. If you would rather use a purpose-built Adams Rite part, the 4036 mortise cylinder is a Grade 1 five-pin option for those doors, and the 4024 and 4025 cylinder pulls are made for the MS1847 deadlock.
5) Which ring do I order with a BEST 12E cylinder?
The ring sets the cylinder depth and dresses the hole, so it follows the prep, not the finish. Rim cylinder rings are for a standard rim mount, tapered cylinder rings for a tapered prep, and 3E mortise, 6-pin mortise or 7-pin mortise rings when the cylinder goes into a mortise application with the matching core length. The RP3 ring package ships with the cylinder for standard rim installs.
6) Does the BEST 12E rim cylinder come with everything needed to install it, or do I need extra parts?
It arrives as a complete package: the cylinder, RP3 ring package, 1E-S2 spindle, clamp plate and clamp plate screws. That covers the mounting on a standard rim application. What you supply is the correct core keying information at order time and, if the device calls for something other than the standard cam, the Adams Rite MS cam option instead.
7) What is the difference between the BEST 12E rim cylinder and a Schlage 20-021 or 20-022 rim cylinder?
The Schlage 20-021 and 20-022 are 6-pin rim cylinders that ship with two keys and a fixed tailpiece cam, vertical on the 20-021 and horizontal on the 20-022, so you pick the one matching your device. The BEST 12E instead takes an interchangeable core, which lets a locksmith rekey the opening by pulling the core with a control key rather than servicing the cylinder. If you want a Schlage-keyed opening with a removable core, the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
8) Is a rim cylinder the right type, or do I need a mortise cylinder?
Rim cylinders like the 12E mount through the door with a clamp plate and drive a rim exit device or rim lock with a spindle, using the 1E-S2 spindle supplied. A mortise cylinder threads into a mortise lock body and turns a cam instead. If your lock body is mortised into the door edge, you want a mortise cylinder: the Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the 1000 Series is a 1-1/2 inch Grade 1 mortise cylinder with an A02 straight cam. The 12E is also offered with mortise ring packages in 3E, 6-pin and 7-pin.
9) What finishes does the BEST 12E rim cylinder come in for matching existing door hardware?
Ten, by BHMA number: 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 building already standardized on 626 satin chrome or 630-family stainless trim, 626 is the usual match on the cylinder face since that is the only part of the cylinder that shows.
10) Is the BEST 12E cylinder durable enough for a high-traffic commercial entrance?
The cylinder body is machined from solid bar stock rather than cast, which is what holds tolerance on a door cycled hard all day. The interchangeable core is the practical durability advantage on a busy opening: when a tenant turns over or a key walks off, you swap the core with a control key in seconds instead of pulling the cylinder off the door.
