BEST 1ED7D4-C4RP3626-LC – Frequently Asked Questions

1) Does the BEST 1ED mortise cylinder come with a core and keys?
No. The 1ED Series mortise cylinder is a less-core housing, so it ships without an interchangeable core and without keys. You order the SFIC core separately in the keyway and keying your building already uses, then drop it into the housing. That is what makes it useful on a master-keyed site: the housing is a stocked shell, and the core carries the keying.
2) What cam comes on the BEST 1ED cylinder, and can I get an Adams Rite cam instead?
The C228 cabinet cylinder cam is the standard build, and that cam prevents key withdrawal in the unlocked position. On the order form the cam choice is a separate selection: standard cam, Adams Rite MS cam for MS-style deadlocks, or a standard spindle. Utility cam lengths run from 5/8 inch up to 3-1/2 inch where the cylinder has to reach further into the lock case.
3) What size is the BEST 1ED mortise cylinder body?
1-5/32 inch diameter, slabbed, and 1-15/32 inch measured from the head to the cam. It is threaded all the way to the head. Check that 1-15/32 inch length against your lock case depth and door thickness before you commit, because a mortise cylinder that sits too deep or too proud will not operate the lock properly.
4) Which locks is the BEST 1ED cylinder meant to go into?
It is built for BEST E Series mortise locks and compatible BEST hardware, and it belongs to the E Series Cylinders collection. If you are replacing a cylinder in a different manufacturer's mortise lock, confirm the cam type matches that lock case first, since cam shape rather than body size is usually what stops a swap.
5) I need a mortise cylinder but my building is not keyed to BEST. What else works?
If you are not on a BEST small-format core system, a fixed-cylinder option is simpler. The Corbin Russwin 1000 Grade 1 mortise cylinder comes at 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 Grade 1 mortise housing is a 1-1/4 inch 6-pin with an A01 cloverleaf cam. For Schlage L9000 mortise locks specifically, the Corbin Russwin 1080 is a 1-1/2 inch 6-pin LFIC cylinder with the A01 Schlage L cam. Match the cam to the lock case first, then the length.
6) Will the BEST 1ED mortise cylinder work in a rim exit device?
No. The 1ED is a threaded mortise cylinder that screws into a mortise lock case, not a rim cylinder with a tailpiece. For a rim device you want a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same with a horizontal cam, or the Schlage 20-057 6-pin FSIC rim cylinder with a convertible tailpiece cam if you are running interchangeable cores.
7) I am working on an aluminum storefront with an Adams Rite MS deadlock. Does the BEST 1ED work, or is there a dedicated part?
The 1ED is offered with an Adams Rite MS cam option, which is the cam profile those MS deadlocks require, so the cylinder itself can serve that application once a core is fitted. If the opening instead needs a cylinder and pull in one assembly, Adams Rite builds the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws, both for MS1847 deadlock and deadlatch systems. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is built for the 5017 wood door deadlock and deadlatch.
8) I need a mortise cylinder that ships with pins and keys already in it, not one that takes an interchangeable core. What should I order instead of the BEST 1ED?
The BEST 1ED Series mortise cylinder is supplied less core, so it needs a separate BEST core to function. If you want a conventional keyed mortise cylinder that arrives complete, the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam is a conventional mortise cylinder, and the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin mortise cylinder. Confirm the cam your lock case requires before ordering, since cam style is what determines whether the cylinder will actually throw the lock.
9) Is a BEST 1ED cylinder the right part for a rim exit device, or do I need something else?
The 1ED is a mortise cylinder with a threaded body that screws into a mortise lock case, so it is not the part for a rim device prep. For rim applications, the Schlage 20-021 is a six-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same rim cylinder with a horizontal tailpiece cam, while the Corbin Russwin 3070 is a six-pin rim cylinder housing with a 1-7/8 inch tailpiece. Pick the tailpiece orientation your exit device chassis calls for.
10) We already run an interchangeable core program. Which other less-core cylinders compare to the BEST 1ED?
The BEST 1ED mortise cylinder is a less-core housing meant to receive a core separately, which is what lets a facility rekey by swapping cores instead of repinning. On the interchangeable core side, the Schlage 20-057 is a six-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the Corbin Russwin 1080 is a 1-1/2 inch six-pin large format interchangeable core mortise cylinder set up for Schlage L9000 mortise locks with an A01 cam. The difference that matters is core format: a BEST core will not seat in a housing built for another manufacturer's core.
11) My tenant doors have key-in-knob and key-in-lever locks. Can I use the 1ED mortise cylinder to rekey them?
No. The 1ED is a threaded mortise cylinder that mounts into a mortise lock case, not a knob or lever cylinder. For key-in-knob and key-in-lever replacement, the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. If the door is a keyed deadbolt instead, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
12) What ring do I get with the BEST 1ED cylinder, and what are the other ring choices?
RP2 is supplied standard on 6-pin and 7-pin configurations unless you specify otherwise. The ring selection on the order form covers 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder and tapered cylinder. Pick the ring that makes up the gap between the lock face and the door face, otherwise the cylinder sits low or stands out from the escutcheon.
13) Can I match BEST 1ED cylinders to the finish on the rest of my door hardware?
Ten finishes are offered: 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 property manager standardizing a building, order the same finish code across every opening rather than matching by eye.
14) What is the difference between the BEST 1ED and the Corbin Russwin 1070 mortise housing?
Both are mortise cylinder housings supplied without a core. The BEST 1ED is a seven-pin slabbed direct motion housing, 1-5/32 inch in diameter and 1-15/32 inch from head to cam, threaded to the head, with a C228 cam standard. The Corbin Russwin 1070 is a 1-1/4 inch six-pin mortise housing furnished with an A01 cloverleaf cam. Choose by the core format your keying system uses and by the cam the lock case needs.
15) I need a mortise cylinder in a Schlage C keyway to match the rest of the building. Is the BEST 1ED an option?
The 1ED is a less core housing, so its keyway is determined by the core you install in it rather than by the cylinder itself. If you want a mortise cylinder that already carries a Schlage C keyway, the Detex MC65 is a 1-1/8 inch six-pin commercial grade mortise cylinder in Schlage C. On the interchangeable core side, the Schlage 20-057-C is a full size interchangeable core in the C keyway, finished 643E aged bronze.
16) Can I put a BEST 1ED cylinder in a residential handleset or deadbolt?
The 1ED is a mortise cylinder body for mortise lock cases and is supplied less core, so it is not a drop-in for a typical residential handleset or deadbolt. For those, Medeco offers rim type lazy motion cylinders: the 1012040 is a six-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a five-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065244 is a five-pin rim lazy motion cylinder with an Emtek tailpiece. For an Arrow JL interconnected lock or an Emtek handleset and deadbolt outside cylinder, the Medeco 1065140 is a five-pin retrofit cylinder.
17) What is the 1ED cylinder made of, and will it hold up in an exterior opening?
Solid brass or bronze construction, which is what gives it corrosion resistance in exterior and high-traffic door use. That is standard practice for mortise cylinders exposed to weather, and it is why BEST specifies brass or bronze rather than a plated pot-metal shell.
18) Is there installation documentation for the BEST 1ED cylinder?
Yes, the BEST E Series Service Manual covers it, and it is the right reference because the 1ED is an E Series cylinder that installs into the parent mortise lock. Follow the lock case instructions for cam orientation and cylinder depth rather than setting it by feel.
19) Is there a simpler cylinder than the BEST 1ED if I just need to replace one on an Emtek door?
The 1ED is a seven-pin mortise housing that requires a separate core and a cam or spindle selection, which is more specification than a single-door swap usually needs. For an Emtek door, the Emtek CY4 cylinder is sold individually, and the Medeco 1065140 is a five-pin retrofit cylinder that covers Emtek handleset and deadbolt outside cylinder use. Verify what the existing lock accepts before choosing.
