BEST 1E04-RP3626 – Frequently Asked Questions

1) Does the BEST 1E Series dummy mortise cylinder come with a core?
No core is included. The 1E dummy mortise cylinder is a less-core housing, so you supply a BEST interchangeable core (or a dummy/blank core) to complete it. It ships with the 3E-C3 cam and RP2 ring package for mortise use, and a diagonal set screw in the cylinder wall holds it in the lock housing. If you already run BEST IC on the building, the cylinder can be master keyed into that existing system.
2) What size mortise cylinder is the BEST 1E, and will it fit a standard mortise lock prep?
It measures 1-5/32 inch diameter by 1-1/8 inch length, which is the standard mortise cylinder size for a normal 1-3/4 inch commercial door with a standard mortise lock case. Nothing longer is needed unless your trim or door build adds material, in which case a longer cylinder is required instead of this one.
3) Which ring do I order with a BEST 1E cylinder?
Five ring choices are offered: 3E Mortise, 6-pin Mortise, 7-pin Mortise, Rim Cylinder, and Tapered Cylinder. Match the ring to the prep and to the pin length of the core family you run, 6-pin or 7-pin, so the core face sits flush with the trim. The tapered ring is the one to pick when the escutcheon or lock face is beveled rather than flat.
4) Will a mortise cylinder work in an exit device or a rim lock?
No. A mortise cylinder threads into a mortise lock case and drives a cam; a rim device needs a rim cylinder with a tailpiece. For rim applications look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. If you want to stay on interchangeable core in a rim opening, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
5) What is the closest equivalent to a BEST 1E dummy mortise cylinder from another manufacturer?
The closest peer in mortise housings is the Corbin Russwin 1070, a Grade 1 series 1-1/4 inch 6-pin mortise housing supplied with an A01 cloverleaf cam. The BEST 1E is a mortise cylinder built for BEST interchangeable core systems and ships with the 3E-C3 cam and RP2 ring package. Both are mortise-format cylinder bodies, so the deciding factor is which core and cam your lock accepts: the 1E carries a BEST interchangeable core, while the Corbin Russwin 1070 is a 6-pin housing on the Corbin Russwin cam standard.
6) I need an interchangeable core cylinder but the lock is a rim device, not a mortise lock. What should I use instead?
For a rim device, the Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. The BEST 1E is a mortise cylinder with a 1-5/32 inch diameter and 1-1/8 inch length that mounts by a diagonal set screw in the lock housing, so it belongs in a mortise pocket rather than behind a rim exit device. If you want the same interchangeable core keying on a rim application, the Schlage 20-057 FSIC route covers it; the 20-057-C is the same full size interchangeable core cylinder in a C keyway with a 643E aged bronze finish.
7) The opening is an aluminum storefront with an Adams Rite deadlock. Will a BEST 1E mortise cylinder work there?
For an Adams Rite MS1847 deadlock or deadlatch, the parts built for that opening are the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws; for a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching piece. Adams Rite also offers the 4036 mortise cylinder, a Grade 1 unit with five-pin security and a 1/2 inch minimum door thickness. The BEST 1E is a 1-5/32 inch diameter, 1-1/8 inch mortise cylinder for BEST interchangeable core systems, so an Adams Rite storefront lock is served by the parts cut for its own prep.
8) What is a dummy mortise cylinder actually for?
A dummy cylinder fills the cylinder hole and gives the opening the same look as a keyed one without operating anything. Common uses are the inactive leaf of a pair, a door where the lock is trim-only, or standardizing appearance across a run of doors so every escutcheon shows the same BEST core face. The 1E takes the same finish and ring options as the keyed E Series cylinders, so it matches next to real ones.
9) Is there a cam difference I need to specify when ordering a BEST 1E mortise cylinder?
The 1E ships with the 3E-C3 cam as standard, so for a BEST mortise lock there is nothing extra to call out. Where cam pattern does become an ordering decision is on other brands: Corbin Russwin mortise cylinders, for instance, are ordered by cam, an A01 cloverleaf on the 1070 housing versus an A02 straight cam on the 1000. Identify the cam your lock case needs before you buy, because the cam, not the housing, is what fails to drive the lock.
10) Can I master key a BEST 1E cylinder into the system already running in my building?
Yes, provided the building is on BEST interchangeable core. The 1E is built for the BEST IC system and can be master keyed into an existing BEST installation, which is what lets a facilities group standardize a whole campus on one key hierarchy and pull or rekey a door by swapping the core rather than the cylinder. As a dummy, this particular housing carries the core for appearance and system consistency rather than operating a bolt.
11) Is a Schlage 20-021 rim cylinder a substitute for a BEST 1E mortise cylinder?
No. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam. A rim cylinder drives a tailpiece through the door into a surface-mounted device; the BEST 1E is a mortise cylinder that threads into the lock case and turns a cam, supplied with the 3E-C3 cam and RP2 ring package. They mount and drive differently, so one does not drop into the other's prep. The BEST 1E is offered with mortise ring configurations including 3E Mortise, 6-pin Mortise and 7-pin Mortise, as well as Rim Cylinder and Tapered Cylinder ring options.
12) Can I use a BEST 1E mortise cylinder to rekey a key-in-knob or key-in-lever lockset?
No, that is a different cylinder format. For knob and lever locksets the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder; the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series 6-pin G keyway, keyed different with two cut keys. For deadbolts, the Kaba Ilco 1549 is a key-in-deadbolt cylinder. The BEST 1E is a mortise cylinder that mounts in a mortise lock housing with a diagonal set screw and turns the 3E-C3 cam, so it serves mortise lock cases rather than knob, lever or deadbolt chassis.
13) Which cylinder do I order for a residential handleset or deadbolt rather than a mortise lock?
For handlesets and deadbolts the Medeco rim-type lazy motion cylinders are the match: the 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. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and Emtek also lists the CY4 cylinder. The BEST 1E is a mortise cylinder for BEST interchangeable core mortise lock applications, which is a different prep entirely.
14) What finishes does the BEST 1E mortise cylinder come in?
Ten finishes, all standard BHMA numbers so they match the rest of the door hardware: 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 matching an existing building, 626 satin chrome and 613 oil-rubbed bronze are the two that most commonly sit alongside existing lever trim.
15) What is the BEST 1E cylinder made of, and will it hold up on an exterior door?
The body is machined from solid brass or bronze bar stock, not cast or plated pot metal, which is why it resists corrosion on exterior and high-traffic openings. Ordering it in a matching architectural finish keeps it consistent with the rest of the trim on the opening.
16) Does a Corbin Russwin 3070 rim cylinder housing replace a BEST 1E mortise cylinder?
No. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece from the 3000 series, so it works from the face of the door into a rim device by way of that tailpiece length. The BEST 1E is a mortise cylinder body, 1-5/32 inch in diameter and 1-1/8 inch long, held by a diagonal set screw in the lock case and driving the 3E-C3 cam. Tailpiece length is the wrong measurement to match against a mortise cylinder's length, so confirm the device format before ordering either one.
17) I need a mortise cylinder that matches oil-rubbed bronze hardware. What are my options across brands?
The BEST 1E mortise cylinder is offered in ten finishes, including 613 Satin Bronze Oil-Rubbed, 690 Statuary Dark Bronze, 611 Bright Bronze, 612 Satin Bronze, 605 Bright Brass, 606 Satin Brass, 619 Satin Nickel, 622 Matte Black, 625 Bright Chrome and 626 Satin Chrome, so dark bronze and oil-rubbed openings are covered directly. On the interchangeable core side, the Schlage 20-057-C full size interchangeable core cylinder is cataloged in 643E aged bronze.
18) Is there installation documentation for BEST E Series cylinders?
Yes. BEST publishes an E Series Service Manual covering the E Series cylinder line, which is the reference for cam and ring selection and for setting the cylinder in the lock housing. Beyond that, the parent lock's own installation instructions govern how deep the cylinder seats and where the set screw lands.
