BEST BES-1ED7D4-C4RP3626-SC – Frequently Asked Questions

1) What length is the BEST 1ED mortise cylinder from the head to the cam?
The 1ED mortise cylinder measures 1-15/32 inches from the head to the cam, on a 1-5/32 inch diameter body. That head-to-cam length is what has to match the mortise lock case pocket, so measure the cylinder you are pulling out before you order. The body is slabbed and threaded all the way to the head, so it threads in to depth rather than bottoming on an unthreaded shank.
2) What does the C228 cam on the BEST 1ED cylinder actually do?
The C228 cabinet cylinder cam stops the key from being pulled out while the cylinder is in the unlocked position. On a cabinet or a controlled opening that is deliberate: the key stays captive until someone relocks, so nobody walks off leaving it unsecured. If you want a cylinder you can key and pull free in either position, that is not the cam to specify.
3) Which BEST keyway do I order so the cylinder works on my existing master key system?
Order the 1ED cylinder in the keyway your system is already built on. Twenty BEST keyways are offered: A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD and TE. The keyway has to match the rest of the system or the key will not enter, so pull the letter off an existing key or your keying schedule rather than guessing. Keymark and marking number are specified with the order as well, which is how the cylinder gets cut into the right level of your system instead of arriving keyed at random.
4) Is the BEST 1ED a 7-pin cylinder, and does it take a standard core?
Seven pins, with a standard core. That matters if your building is on a 6-pin BEST system: the pin count has to match the system the key is cut to. The RP2 ring package ships standard with both the 6-pin and 7-pin builds unless you call out something different.
5) Will a BEST 1ED cylinder work in a Schlage or Corbin mortise lock?
The 1ED is a replacement mortise cylinder built for BEST keying, and the fit into any given lock case comes down to the cam and the threaded length rather than the brand on the lock. If your building is standardized on Corbin Russwin keying instead, the Corbin Russwin 1000 Series 1-1/2 inch mortise cylinder with the A02 straight cam is the parallel part, and the 1080 Series 1-1/2 inch LFIC mortise cylinder is listed for Schlage L9000 mortise locks with an A01 cam. Match the cylinder to the keying system you are staying on.
6) I need a cylinder for a rim exit device, not a mortise lock. Is the BEST 1ED the right part?
No. The 1ED is a mortise cylinder, which threads into the lock case; a rim device takes a rim cylinder with a tailpiece that passes through the door into the back of the device. For that, look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam, the 20-022 with a horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. Which tailpiece orientation you need depends on the exit device.
7) I am replacing cylinders across a whole apartment building. Can I keep them all on one key system with the BEST 1ED?
Yes, and that is the reason to buy the series rather than one-off cylinders. Every 1ED is ordered with a keyway letter plus a keymark and marking number, so a run of them can be cut into the same master key system and keyed alike or keyed different unit by unit. Keep the keyway consistent across the order and the building stays on one key hierarchy. The 1ED family shares keying and installation standards across its cylinder types, which is what lets a mortise opening and a rim opening sit on the same key.
8) Can a BEST 1ED mortise cylinder be used in an Adams Rite MS deadlock on an aluminum storefront?
The 1ED is offered with an Adams Rite MS cam among its cam and spindle options, alongside the standard cam and standard spindle, so it can be built for that application. Where the storefront needs a cylinder that also serves as the pull, the Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock. Those are pull assemblies rather than a plain mortise cylinder, so the choice depends on whether the door already has a pull.
9) What is the closest equivalent to a BEST 1ED mortise cylinder if the mortise lock body needs a straight cam instead?
The BEST 1ED is a slabbed direct motion mortise cylinder built with a C228 cabinet cylinder cam, which prevents the key being withdrawn in the unlocked position. If the mortise lock body calls for a straight cam, the Corbin Russwin 1000 Grade 1 Series mortise cylinder is a 1-1/2 inch length cylinder supplied with an A02 straight cam. Confirm which cam profile the lock case actually accepts before ordering, since the cam is what drives the lock hub and the two profiles are not interchangeable.
10) Which mortise cylinder should a locksmith use when the lock body needs a cloverleaf cam rather than a cabinet cam?
The BEST 1ED ships with the C228 cabinet cylinder cam. For a cloverleaf cam, the Corbin Russwin 1070 Grade 1 Series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Cloverleaf cams are what many mortise lock cases and exit device trims are prepped for, so match the cam to the lock case prep, not to the cylinder diameter alone.
11) What cylinder replaces a BEST 1ED when the opening uses a Schlage L9000 mortise lock?
The BEST 1ED is a mortise cylinder taking a BEST standard core in a 7-pin format. For a Schlage L9000 mortise lock, the Corbin Russwin 1080 Grade 1 Series is a 1-1/2 inch large format interchangeable core mortise cylinder, 6-pin, specified for Schlage L9000 mortise locks with the A01 Schlage L cam. The Schlage L cam is the deciding detail there; the core format and cam must both suit the lock case.
12) Is a rim cylinder a valid substitute for a mortise cylinder on an exit device?
No. The BEST 1ED is a threaded, slabbed mortise cylinder that screws into a mortise lock case and turns a cam. A rim cylinder mounts through the door and drives a tailpiece instead: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Rim and mortise cylinders are not interchangeable, and on rim devices the tailpiece orientation, vertical or horizontal, has to match the device.
13) What mortise cylinder carries an ANSI Grade 1 rating for an institutional specification?
The Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1, with a 1/2 inch minimum door thickness. The BEST 1ED is a 7-pin slabbed mortise cylinder in solid brass or bronze with the C228 cam. If the drawing calls out a Grade 1 cylinder by name, the 4036 answers that line item directly; if the requirement is a 7-pin BEST keyed system, the 1ED is the one that keys into it.
14) What is the alternative to a BEST 1ED mortise cylinder when the door has a key-in-knob or key-in-lever lockset instead of a mortise lock?
A mortise cylinder like the 1ED threads into a mortise lock case and will not fit a cylindrical lockset. For knob and lever locks, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, and the Kaba Ilco 1579 is a knob and lever cylinder for Sargent. For a keyed deadbolt, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder. Identify the lock family on the door first, because the cylinder body shape follows the lock, not the keyway.
15) What ring options come with the BEST 1ED cylinder, and which one do I need?
Rings are specified with the order in five forms: 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder and tapered cylinder. The ring is the spacer that takes up the gap between the cylinder head and the face of the door or lock trim, so pick it by how far the cylinder sits proud once threaded to depth. On a 7-pin mortise install, the 7-pin mortise ring is the matching choice; the tapered ring is for where you want the head faired into the trim rather than sitting flat.
16) I need a longer cam to reach the lock mechanism. What are my options on the BEST 1ED?
Utility cams are available from 5/8 inch out to 3-1/2 inch on the 1ED. That covers deep lock cases and thick door or trim stack-ups where a standard cam simply does not reach the retractor. Measure from the cam seat to the point the cam has to engage and order the length that closes that gap.
17) What finishes does the BEST 1ED mortise 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. For a building standardized on satin chrome trim, 626 is the match; 613 is the usual pick against oil-rubbed bronze levers. Only the cylinder head shows once installed, so match it to the escutcheon or rose, not to the lock body.
18) What is the BEST 1ED cylinder made of, and will it hold up on an exterior apartment entry?
Solid brass or bronze construction, which is why it holds up against corrosion on exterior openings. The 1ED is positioned for residential and light commercial use: apartment and condo entries, multi-unit housing, small commercial and property management work. For a high-traffic institutional opening where a Grade 1 rating is written into the spec, the Corbin Russwin 1000 or 1070 Grade 1 mortise cylinders are the ones that carry that grade.
19) I have an Adams Rite MS1847 deadlock. Do I need the BEST 1ED or a cylinder pull?
Depends on what the door is missing. If the deadlock is in place and you only need the key cylinder, the 1ED with the Adams Rite MS cam is the option to specify. If the door has no pull and you need the cylinder and the pull as one assembly, the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws are both listed for the MS1847 deadlock. On a wood door with the 5017 deadlock, the Adams Rite 4026 is the matching pull.
20) What is the difference between a BEST 1ED standard core cylinder and a full size interchangeable core cylinder?
The BEST 1ED takes a standard core in a 7-pin configuration and is supplied with the RP2 ring package for 6-pin and 7-pin builds. A full size interchangeable core product works differently: the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the Schlage 20-057-C is a full size interchangeable core cylinder in C keyway with a 643E aged bronze finish. With FSIC, the core pulls with a control key so rekeying is a core swap; with a standard core, the cylinder is pinned in place. Pick the one that matches how the facility rekeys.
21) What replaces a mortise cylinder on a residential handleset or Kwikset deadbolt?
The BEST 1ED is a mortise cylinder for mortise lock assemblies. Residential deadbolts and handlesets generally take a rim type lazy motion cylinder instead: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Lazy motion describes how the cylinder drives the bolt and is specific to those lock bodies.
22) Which cylinder suits an Emtek handleset or an Arrow JL interconnected lock rather than a mortise case?
Those openings need a cylinder built for their specific lock body. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for the Emtek handleset and deadbolt outside cylinder, and the Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece. The Emtek CY4 is another cylinder in the Emtek parts range. The BEST 1ED, being a threaded mortise cylinder driving a cam, is not a retrofit for any of these.
23) How does a 7-pin BEST 1ED compare with a 6-pin mortise cylinder for keying a building?
The BEST 1ED is a 7-pin cylinder in a 1-5/32 inch slabbed body, offered across keyways A through R plus TB, TC, TD and TE. Comparable 6-pin mortise options include the Detex MC65, a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Corbin Russwin 1070, a 1-1/4 inch 6-pin mortise housing. Pin count and keyway both have to match the existing master key system, so the choice follows whatever the building is already keyed to.
24) What should be ordered instead of a mortise cylinder when the exit device takes a rim cylinder housing?
A rim device needs a rim housing, not a threaded mortise body. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece in the 3000 Series. The BEST 1ED is available in a rim cylinder ring configuration alongside 3E mortise, 6-pin mortise, 7-pin mortise and tapered cylinder rings, so the ring package chosen has to follow the mounting the door actually has.
25) Which mortise cylinder works on a very thin aluminum door?
Door thickness governs here. The Adams Rite 4036 five-pin mortise cylinder is rated for a 1/2 inch minimum door thickness and carries a Grade 1 rating, which suits thin stile aluminum work. The BEST 1ED is a 1-5/32 inch diameter cylinder with 1-15/32 inch length from head to cam, and it is also offered with utility cam lengths from 5/8 inch to 3-1/2 inch where the application needs extended reach. Measure the stile and the cam travel required before choosing.
26) What is the substitute for a BEST 1ED cylinder on a wood door Adams Rite deadlatch?
The Adams Rite 4026 is a five pin tumbler cylinder pull designed for wood door applications with the Adams Rite 5017 wood door deadlock and deadlatch. That differs from the 4024 and 4025 cylinder pulls, which are for the MS1847 deadlock and deadlatch. The BEST 1ED can be supplied with an Adams Rite MS cam, so the deciding factor is which Adams Rite lock body is in the door and whether a pull is needed with it.
27) Do I get rings with the BEST 1ED cylinder or do I order them separately?
The RP2 ring package ships standard with the 6-pin and 7-pin cylinders unless you specify otherwise, so a normal order arrives with rings. If your install needs a different profile, the ring is a selectable option and can be called out as 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder or tapered.
28) Is there an installation manual for BEST E Series cylinders?
Yes. BEST publishes an E Series Service Manual covering these cylinders, and it is the reference for cam changes, ring selection and coring. The 1ED is part of the E Series cylinder collection, so that manual applies. For the lock case itself, work from the manufacturer's instructions for the parent device, since the cylinder is a replacement component going into hardware someone else built.
29) Is a key-in-lever cylinder from a Falcon lockset the same thing as a BEST mortise cylinder?
No. 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 two cut keys. It seats inside a lever lockset. The BEST 1ED is a 1-5/32 inch slabbed mortise cylinder threaded to the head that screws into a mortise lock case and drives a C228 cam. They serve different lock bodies even though both are called cylinders.
