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

1) What size is the BEST 1ED mortise cylinder and how far does it reach into the lock?
The 1ED mortise cylinder is 1-5/32 inches in diameter, slabbed and threaded to the head, and measures 1-15/32 inches from head to cam in the 7-pin configuration. That head-to-cam length is what determines whether the cam lands on the lock's actuator, so measure the cylinder you are pulling out before you order.
2) What does the C228 cam on this BEST cylinder actually do?
The C228 cabinet cylinder cam stops the key from being pulled out while the lock sits in the unlocked position. On cabinet and similar applications that forces the user to relock before retrieving the key. If you do not want that behavior on a standard mortise lock, order the standard cam instead, which is one of the cam choices offered.
3) Can I get this BEST cylinder with an Adams Rite cam for a storefront deadlock?
Yes. Cam and spindle choices on the 1ED cylinder include an Adams Rite MS cam, a standard cam, and a standard spindle. The Adams Rite MS cam is the one to pick when the cylinder is driving an Adams Rite MS-type deadlock in an aluminum storefront door.
4) What do I have to specify when ordering a BEST 1ED cylinder?
Three things are required at order: the keyway, the keymark, and the marking number. Keyway choices are WA, WB, WC, WD, WE, WG, WH, WK and WY. The keymark and marking number are free-text so the cylinder is cut and stamped to your existing master key system. On top of that you pick finish, cam or spindle option, and ring package.
5) Will a 7-pin BEST cylinder work on my existing BEST master key system?
It can, provided the keyway and keymark you specify match your system. The 1ED is a 7-pin cylinder, so it keys into a 7-pin BEST system; a 6-pin system uses the 6-pin body and ring. Give us your keyway letter (WA through WY) plus the keymark and marking number off your existing cylinders and the core is built to that system.
6) I need a mortise cylinder but I am not on a BEST keyway. What else is there?
If your building keys to another system, look at a mortise housing in that brand instead. 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 is a 1-1/4 inch 6-pin with an A01 cloverleaf cam. For Schlage L9000 mortise locks there is the Corbin Russwin 1080 Grade 1 1-1/2 inch LFIC 6-pin with the A01 Schlage L cam. The Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway.
7) What is a comparable mortise cylinder to the BEST 1ED Series if the lock takes a Corbin Russwin keyway?
The Corbin Russwin 1000 Grade 1 Series mortise cylinder covers that opening. It measures 1-1/2 inches in length and comes with an A02 straight cam, where the BEST 1ED Series 7-pin cylinder measures 1-15/32 inches from head to cam and ships with the C228 cabinet cylinder cam. If the mortise lock needs a cloverleaf cam instead, the Corbin Russwin 1070 Grade 1 Series 1-1/4 inch 6-pin mortise housing uses an A01 cloverleaf cam.
8) I need a mortise cylinder for Schlage L9000 mortise locks instead of a BEST mortise lock - what should I order?
The Corbin Russwin 1080 Grade 1 Series 1-1/2 inch 6-pin large format interchangeable core mortise cylinder is built for Schlage L9000 mortise locks and uses an A01 Schlage L cam. The BEST 1ED Series is a 7-pin slabbed direct motion cylinder supplied with the C228 cam and RP2 ring package for compatible BEST mortise lock systems.
9) The door has a rim exit device, not a mortise lock - what cylinder do I use instead of the BEST 1ED mortise cylinder?
For a rim device, Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; pick the orientation the device calls for. Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The BEST 1ED Series is a mortise cylinder, threaded and slabbed to the head at 1-5/32 inch diameter, though a Rim Cylinder ring option is offered.
10) What is the difference between the BEST 1ED mortise cylinder and the Adams Rite 4036 mortise cylinder?
The Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness. The BEST 1ED Series is a 7-pin cylinder, and it is offered with an Adams Rite MS Cam option if you are driving an Adams Rite MS deadlock with a BEST keyway.
11) Which ring package do I order with a BEST 1ED mortise cylinder?
The RP2 ring package ships as the standard setup, and ring selection is an order choice: 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder, or tapered cylinder. Match the ring to the pin count and body style you are installing, since the rings take up the gap between the door face or lock face and the cylinder head.
12) What finishes can I get to match the rest of the hardware on the door?
Ten finishes are offered on the 1ED cylinder: 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. Bodies are solid brass or bronze, which also helps on exterior and humid locations.
13) Is a 7-pin cylinder worth it over a standard 6-pin for key control?
The extra pin chamber gives you more differs and a longer key bitting, which is why the 7-pin arrangement is described as offering better key control and pick resistance than 5 or 6-pin cylinders. For a facility running a large master key system that matters. If you are simply replacing one cylinder on a 6-pin building system, stay with 6-pin so the keys still interchange.
14) Can I use this mortise cylinder in an exit device rim application?
No. A mortise cylinder threads into the lock body and turns a cam; a rim device needs a rim cylinder with a tailpiece. For that use a rim housing such as the Schlage 20-021 6-pin with vertical tailpiece cam or the 20-022 with horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. Note the 1ED does offer a rim cylinder ring option, but the cylinder body itself is the mortise type.
15) Does a cylinder like this come with a pull or trim for a narrow stile aluminum door?
No. The 1ED is the cylinder only, a replacement part that goes into an existing lock body. If you need the cylinder combined with a pull for a storefront deadlock, the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler pull with through-screws both suit MS1847 deadlocks, and the 4026 five pin pull is for wood door applications with the 5017 deadlock.
16) Is a key-in-knob or key-in-lever replacement cylinder a substitute for the BEST 1ED mortise cylinder?
No. The Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder and the 1599 Series is a key-in-knob replacement cylinder; the 1579 Series is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder in a 6-pin G keyway. Those drop into the knob or lever itself. The BEST 1ED Series is a threaded mortise cylinder that screws into the mortise lock case body.
17) Which cylinder should I use for a deadbolt rather than the BEST 1ED mortise cylinder?
For deadbolt applications, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts along with the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The BEST 1ED Series is a direct motion mortise cylinder for mortise lock bodies.
18) I want interchangeable cores rather than the BEST 1ED premium core - what are my options?
Schlage Commercial 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is a full size interchangeable core in the C keyway, 643E aged bronze. In mortise format, the Corbin Russwin 1080 Grade 1 Series is a 1-1/2 inch 6-pin large format interchangeable core cylinder. The BEST 1ED Series is ordered with a premium core in a BEST keyway from WA through WY.
19) How does the Detex MC65 mortise cylinder compare with the BEST 1ED Series?
The Detex MC65 is a 6-pin commercial grade mortise cylinder measuring 1-1/8 inch in the Schlage C keyway. The BEST 1ED Series is a 7-pin cylinder at 1-5/32 inch diameter with 1-15/32 inch from head to cam, ordered in BEST keyways, and is available in ten finishes from 605 bright brass to 690 statuary dark bronze.
20) I am replacing a cylinder in an Emtek handleset - is the BEST 1ED the right part?
No. For Emtek, the Emtek CY4 cylinder is the brand's own part, and Medeco offers the 1065244 5-pin rim lazy motion cylinder with an Emtek tailpiece plus the 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. The BEST 1ED Series is a mortise cylinder for compatible BEST mortise lock systems.
21) Is the BEST 1ED an interchangeable core cylinder?
The 1ED is supplied as a complete mortise cylinder with a premium core, keyed to the keyway, keymark and marking number you specify. If what you need instead is a swappable full size interchangeable core for rekeying on the fly, the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam or the 20-057-C FSIC core in C keyway are the interchangeable-core route.
22) Is there installation documentation for the BEST E Series cylinders?
Yes, the E Series Service Manual covers these cylinders and is available as a PDF. Because the 1ED is a component, you also want the installation instructions for the mortise lock it is going into, since the cam and ring stack-up depend on that lock body.
