BEST BES-1E04-C4RP3626 – Frequently Asked Questions

1) What is a BEST 1E dummy mortise cylinder actually for if it doesn't have a working key?
A dummy mortise cylinder fills the cylinder hole in a mortise lock or trim where you want the look of a keyed cylinder without a working keyway. The BEST 1E version is a solid brass or bronze housing machined from bar stock, 1-5/32 inch diameter and 1-1/8 inch long, and it takes the same BEST interchangeable core as the keyed cylinders, so if the opening later needs to be keyed you drop a core in rather than replacing the housing. Common use is on the inactive leaf of a pair, on a push/pull side, or on trim that has a cylinder prep you are not using.
2) Can a BEST 1E cylinder be keyed into the BEST master key system we already run in the building?
Yes. The 1E takes the BEST interchangeable core and may be master keyed into any existing BEST system, so a facility already standardized on BEST cores keeps one key hierarchy across the openings. For a property manager or MRO buyer that is the whole point: the housing is the fixed part in the door, and the core is what carries the keying, so you swap keying later with a control key instead of pulling the lock apart.
3) Will a BEST 1E mortise cylinder work in a lock made by another manufacturer?
It can. The 1E housing is 1-5/32 inch diameter, which is the standard mortise cylinder thread size, and BEST states it may be altered to function with other manufacturers' locks by using a different cam and different cylinder rings. What you have to get right is the cam: the standard build ships with the 3E-C3 cam and RP2 ring package, and other brands' mortise locks want their own cam profile. An Adams Rite MS cam is one of the cam choices offered on the 1E for Adams Rite MS deadlocks.
4) I need a keyed mortise cylinder, not a dummy. What should I buy instead?
A dummy has no working keyway, so if the door needs to lock or unlock by key it is the wrong part. For a keyed mortise cylinder we carry the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam, the Corbin Russwin 1070 Grade 1 mortise housing in 1-1/4 inch with an A01 cloverleaf cam, and the Detex MC65 mortise cylinder, a 1-1/8 inch 6-pin with a Schlage C keyway. Match the cam to your lock before anything else.
5) Can I use a 1E mortise cylinder on a rim exit device?
No. A mortise cylinder threads into the lock body and turns a cam; a rim device needs a rim cylinder with a tailpiece, which is a different part even though the core is the same family. For rim applications we carry the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, and the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. If you want to stay on an interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
6) Will a BEST 1E mortise cylinder work in an Adams Rite MS deadlock, or do I need an Adams Rite part?
The 1E Series is offered with an Adams Rite MS cam as a cam option, alongside the standard cam, which is what adapts a mortise cylinder to an Adams Rite MS-style deadlock. If you would rather stay entirely on Adams Rite hardware, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security and a 1/2 inch minimum door thickness. For an MS1847 deadlock or deadlatch where the cylinder also serves as the door pull, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 five pin tumbler cylinder pull mounts with through-screws.
7) What is the closest equivalent to a BEST 1E mortise cylinder if the building is keyed to a Corbin Russwin system?
The BEST 1E Series is a mortise cylinder built around the BEST interchangeable core, so it master-keys into an existing BEST system. Where the opening is on a Corbin Russwin system instead, the Corbin Russwin 1000 Grade 1 Series mortise cylinder in 1-1/2 inch length with an A02 straight cam covers the same mortise position, and the Corbin Russwin 1070 Grade 1 Series 1-1/4 inch 6-pin mortise housing does the same with an A01 cloverleaf cam. Match the cam to the mortise lock you are feeding: the 1E ships with the standard 3E-C3 cam unless a different cam is specified.
8) I need an interchangeable core cylinder but the system is Schlage, not BEST. What do I use?
The BEST 1E Series carries the BEST interchangeable core and can be master-keyed into any existing BEST system, which is what makes it the wrong pick on a Schlage-cored building. For a Schlage full-size interchangeable core application, 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 the C keyway, supplied in 643E aged bronze. Note the format difference: those two are rim-side FSIC parts, while the 1E is a mortise cylinder.
9) What do I order if I need a rim cylinder rather than a mortise cylinder?
The BEST 1E Series is configured with a Rim Cylinder ring among its ring options, so the rim format is covered within the series. Straight rim alternatives include the Schlage Commercial 20-021 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, both supplied with 2 keys, and the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The tailpiece orientation and length are what decide the fit, so confirm what the exit device or rim lock behind the door expects.
10) I am replacing the cylinder in a knob or lever lockset, not a mortise lock. Is a 1E the right part?
No. The BEST 1E Series is a mortise cylinder for mortise lock hardware. A key-in-knob or key-in-lever lockset takes a different cylinder body: the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, and the 1599 Series is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key in lever cylinder for the RU/T Series with a 6-pin G keyway, keyed different and supplied with 2 cut keys.
11) Which cylinder do I use for a Schlage L9000 mortise lock?
The Corbin Russwin 1080 Grade 1 Series is a 1-1/2 inch LFIC mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with an A01 Schlage L cam. The BEST 1E Series is a mortise cylinder that may be altered to function with other manufacturers' locks by using different cams and different cylinder rings, so the cam selection is the deciding detail either way.
12) What ring do I specify on a BEST 1E cylinder, and does it depend on 6-pin or 7-pin?
The ring is a separate ordering choice: 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder, or tapered cylinder. Pick the ring to match the core depth you are running (BEST systems are commonly 6-pin or 7-pin) and to make up the difference between the 1-1/8 inch cylinder length and the depth of the cylinder prep in your lock. A tapered ring is the one to reach for when you want the cylinder to sit flush against a sloped or decorative escutcheon.
13) How does the 1E cylinder stay in the lock body, and can it be twisted out?
A diagonal set screw mounts through the cylinder wall and holds the cylinder in the housing. That is the retention detail a locksmith cares about, because a cylinder that only relies on thread friction can be wrenched. On install, thread the cylinder in to the correct depth using the ring stack first, then set the screw.
14) Is a BEST interchangeable core the same as a Schlage full size interchangeable core?
They are not interchangeable. The 1E is built around the BEST interchangeable core, and a Schlage FSIC core, such as the 20-057-C in C keyway and 643E aged bronze, is a different core format on a different control key. If a facility is already on Schlage FSIC, adding BEST housings means running a second key system. Pick one core standard per building and stay on it.
15) Does a dummy cylinder ship with a core in it?
Order the core separately. A dummy 1E is the housing, cam and ring package (3E-C3 cam and RP2 rings as standard), and the BEST interchangeable core is what carries the pinning and keying. Buyers standardizing a building typically buy housings by finish and length and pin their own cores, or have them keyed into the existing system. Specify cam and ring on the order; leave them blank and you get the standard mortise configuration.
16) Is the 1-5/32 inch diameter on the BEST 1E a standard mortise cylinder size?
Yes, 1-5/32 inch is the standard mortise cylinder thread diameter, which is why the 1E drops into mortise locks generally rather than only BEST bodies. The variable that decides fit is length and ring stack, not diameter: the cylinder itself is 1-1/8 inch, and the ring choice makes up the rest so the face sits flush with the trim and the cam engages the lock at the right depth.
17) The opening is an aluminum storefront with a wood door instead. Is the Adams Rite 4036 still the right cylinder?
The Adams Rite 4036 is a mortise cylinder with five-pin security rated Grade 1, with a 1/2 inch minimum door thickness. For a wood door running an Adams Rite 5017 wood door deadlock or deadlatch, the Adams Rite 4026 five pin tumbler cylinder pull is the part built for that lock. The BEST 1E Series is a mortise cylinder that feeds a mortise lock body and does not itself serve as a pull.
18) What cylinder goes into a deadbolt if the 1E mortise cylinder does not fit?
For a key-in-deadbolt application the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder. On residential-style handlesets and deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. The BEST 1E Series is a mortise cylinder and is specified against a mortise lock body instead.
19) Can I use a BEST 1E cylinder on an Emtek handleset?
Emtek trim takes its own cylinder parts. The Emtek CY4 cylinder is sold each for Emtek applications, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, and the Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece. The BEST 1E Series is a mortise cylinder specified against mortise lock hardware.
20) How do I match a replacement cylinder to the finish already on the other doors?
The BEST 1E Series is stocked across 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, so a fleet standardized on any of those BHMA numbers can be matched exactly. Among the comparables, the Schlage 20-057-C full size interchangeable core is specified in 643E aged bronze, so check the finish code before treating it as a visual match for an existing opening.
21) What is the difference between the Corbin Russwin 1070 and 1080 mortise cylinders when cross-referencing a BEST 1E?
The Corbin Russwin 1070 Grade 1 Series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. The Corbin Russwin 1080 Grade 1 Series is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 Schlage L cam. The BEST 1E Series is offered with 6-pin mortise and 7-pin mortise ring configurations along with the 3E mortise ring, so pin count and cam are the two points to confirm when cross-referencing between them.
22) What finishes does the BEST 1E cylinder come in to match the rest of my 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. Those are standard BHMA finish numbers, so 626 satin chrome on the cylinder matches 626 on your levers and 630 stainless trim will read close but not identical.
