BEST 1ER702626 – Frequently Asked Questions

1) What does a BEST 1E cylinder ring actually do, and is it the cylinder or just the collar?
It is the collar, not the cylinder. The BEST 1E Series special cylinder ring is a spacer that sits behind the mortise cylinder face, and it is sold as a replacement part on its own. Its job is twofold: take up the space between cylinder and lock face so the cylinder seats flush, and, together with the right cam, let a BEST 1E cylinder work in another manufacturer's mortise lock. If you need the keyed cylinder itself, that is a separate order.
2) Can I use a BEST interchangeable core cylinder in a non-BEST mortise lock?
That is exactly what this ring is for. BEST 1E Series cylinders adapt to other manufacturers' mortise locks through a combination of the correct cam and the correct ring, and the straight ring covers mortise applications that deviate from the standard 1E-C4 cam setup. Get the cam right first, since the cam is what drives the lock hub; the ring only sets depth. If your existing lock brand needs a cloverleaf-style cam instead, that is a different cylinder entirely, for instance a Corbin Russwin 1080 LFIC mortise cylinder with an A01 cam is what goes into Schlage L9000 mortise locks.
3) Will a straight BEST cylinder ring work on a rim cylinder or an exit device?
No. The straight 1E ring is cut for mortise applications, where the cylinder threads into the lock body. Rim cylinders mount through the door on a back plate with a tailpiece and take no threaded collar, so this part does nothing for them. For a rim application, order a rim cylinder instead, such as the Schlage 20-021 with a vertical tailpiece cam, the 20-022 with a horizontal tailpiece cam, or the 20-057 FSIC rim cylinder if you want an interchangeable core.
4) What is the difference between a BEST 1E Series special cylinder ring and a complete mortise cylinder like the Corbin Russwin 1000?
They do different jobs in the same opening. The BEST 1E Series special cylinder ring is a replacement part that sits between the cylinder and the lock housing, machined from brass or bronze bar stock, and it comes in thicknesses from R702 at 1/8 inch up to R712 at 3/4 inch so a BEST cylinder can be set at the right projection in another maker's mortise lock. The Corbin Russwin CR1000-112 is the cylinder itself - a 1000 Grade 1 Series mortise cylinder, 1-1/2 inch length, with an A02 straight cam. If the keyed cylinder in the door is worn or being rekeyed to a different system, the Corbin Russwin 1000 is the part that changes; if the BEST cylinder is correct and only sits too deep or too proud in the housing, the ring is the part that changes.
5) I need an interchangeable core mortise cylinder for a Schlage L9000 lock, not a spacer ring - what should I order?
The Corbin Russwin CR1080-112-A01 is the part for that opening. It is a 1080 Grade 1 Series 1-1/2 inch LFIC mortise cylinder, 6-pin, specified for Schlage L9000 mortise locks, with an A01 Schlage L cam. That is a complete keyed cylinder with a large format interchangeable core. The BEST 1E Series special cylinder ring is a replacement part in the E Series cylinder family - it adapts the depth and cam arrangement of a BEST cylinder already in hand and does not key anything on its own.
6) The opening takes a rim cylinder, not a mortise cylinder - what are the options there?
The BEST 1E Series special cylinder ring in straight configuration is built for mortise applications, so a rim device needs a different part. The Corbin Russwin 3070-178 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same rim cylinder with a horizontal tailpiece cam. Which of the two Schlage rim cylinders fits depends on the orientation the exit device's cam expects.
7) Our locks are keyed to Schlage C, not to a BEST system - is there a mortise cylinder that matches?
The Detex MC65 is a mortise cylinder with the Schlage C keyway, 1-1/8 inch, 6-pin, commercial grade, so it keys into an existing Schlage C system directly. The BEST 1E Series special cylinder ring belongs to a BEST cylinder that may be master-keyed into any existing BEST system, which is a separate key system from Schlage C. Standardizing a building on one keyway usually means choosing the cylinder first and the ring thickness afterward.
8) What finishes does the BEST 1E cylinder ring come in so it matches my existing trim?
Six finishes, all standard BHMA numbers so they line up with the rest of the hardware on the opening: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Satin chrome 626 is the usual match for commercial lever and mortise trim; 613 is the one to pick against oil-rubbed bronze entry hardware.
9) Do I have to re-key anything if I add a BEST 1E cylinder ring to an existing masterkey system?
No. The ring is a plain machined brass or bronze spacer with no pins or keying in it, so it does not touch key management at all. The BEST 1E cylinder it sits behind uses interchangeable core technology and can be masterkeyed into any existing BEST system, which is why property managers standardizing a building can add or swap rings on individual doors without disturbing the keying plan.
10) I am replacing the whole mortise cylinder, not just the collar. What are my options besides BEST?
If the lock is being re-cylindered rather than shimmed, you are choosing by cam and length. The Corbin Russwin 1000 Grade 1 mortise cylinder comes in 1-1/2 inch length with an A02 straight cam, and the 1070 Grade 1 housing in 1-1/4 inch with an A01 cloverleaf cam. Detex offers the MC65 mortise cylinder in 1-1/8 inch, 6-pin, Schlage C keyway. For aluminum storefront, the Adams Rite 4036 five-pin mortise cylinder is Grade 1 and works down to a 1/2 inch minimum door thickness. The BEST 1E ring only matters once you have settled the cylinder and cam.
11) Is a BEST cylinder ring a substitute for an interchangeable core cylinder from another manufacturer?
No. The BEST 1E Series special cylinder ring is an adaptation component; the interchangeable core it works alongside is the keyed part. If the goal is an interchangeable core cylinder in its own right, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, 643E aged bronze. Both are complete FSIC parts. The BEST ring instead lets a BEST cylinder, which uses BEST interchangeable core technology and may be master-keyed into an existing BEST system, sit correctly in another maker's lock.
12) The door is a narrow stile aluminum storefront with an Adams Rite deadlock - does a BEST cylinder ring apply?
That opening calls for Adams Rite parts built around the deadlock rather than a BEST adaptation ring. The Adams Rite 4036 is a mortise cylinder with five-pin security, Grade 1, in the 4036 Series, with a 1/2 inch minimum door thickness. For a cylinder pull on an MS1847 deadlock or deadlatch, the Adams Rite 4024 uses a trim plate mounting and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws. The BEST 1E Series special cylinder ring is a straight configuration part for mortise applications that adapt a BEST cylinder to another maker's lock.
13) What is the difference between the straight cam arrangement here and a cloverleaf cam cylinder?
Cam shape decides what the cylinder can drive inside the lock case. The BEST 1E Series special cylinder ring in straight configuration is made for mortise applications adapting from standard 1E-C4 cam systems. On the Corbin Russwin side, the CR1070-114-A01 is a 1070 Grade 1 Series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, while the CR1000-112 is a 1000 Grade 1 Series mortise cylinder, 1-1/2 inch, with an A02 straight cam. Confirm which cam the lock case takes before ordering either the ring or the cylinder, because a cam that does not match the lock's hub will not retract the bolt.
14) We are replacing the cylinder in a key-in-knob or key-in-lever lockset - is a cylinder ring part of that job?
Not usually. The BEST 1E Series special cylinder ring is a mortise adaptation part. For knob and lever work, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. For a deadbolt, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder. The Falcon A23161-05 G is a key in lever cylinder, RU/T Series 6-pin G keyway, keyed different, supplied with two cut keys. Match the cylinder to the lockset brand and series already on the door.
15) The handleset and deadbolt on a residential entry need a retrofit cylinder - what fits instead of a mortise ring?
Those entries take a rim type lazy motion cylinder rather than a mortise adaptation ring. 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. For Emtek hardware, the Medeco 1065244 is a 5-pin rim lazy motion rim type 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 the Emtek CY4 is an Emtek cylinder sold each.
16) Is one BEST 1E cylinder ring enough for a double cylinder mortise lock?
Each ring serves one cylinder, so a double cylinder mortise lock needs two, and the two sides do not necessarily take the same thickness. Trim, escutcheons and door prep differ inside versus outside, so measure each face separately and order the matching step from the 1/8 inch through 3/4 inch range. Finish should be ordered per side as well if the two faces of the opening are finished differently.
17) Are BEST 1E cylinder rings solid metal or plated pot metal?
Solid. The 1E Series rings are machined from brass or bronze bar stock, not cast or stamped, which is why the threads and the seat against the lock face hold up to repeated cylinder removal in a keying program. That matters on doors where cores get pulled and re-pinned regularly rather than left alone for years.
18) Can I match the ring to the finish of the cylinders already installed?
The BEST 1E Series special cylinder ring in straight configuration is offered in 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome, so it can be brought in line with the trim already on the door. Among the comparable cylinders, the Schlage 20-057-C full size interchangeable core cylinder is specified in 643E aged bronze with a C keyway. Where a building is being standardized, choosing one finish code across cylinders and rings keeps replacement stock simple.
