BEST 3E74C4RP3626-LC – Frequently Asked Questions

1) Does the BEST 3E Series mortise cylinder come with a core and keys?
No. The 3E Series 1-1/2 inch mortise cylinder is a less core housing, so you supply the interchangeable core and keys separately. That is the point of it for a locksmith managing a keying system: the housing goes in, and your own 7-pin core drops into the existing key hierarchy without recutting anything.
2) What door thicknesses will the BEST 3E mortise cylinder work on?
It covers doors from 7/8 inch up to 2-1/2 inch. The ring package is what makes that range work: the RP4 package ships with a 3E-R2 (1/8 inch) and a 3E-R4 (1/4 inch) ring, so you shim the cylinder out until the face sits flush with the trim instead of standing proud or sinking below it.
3) Which cam does the BEST 3E mortise cylinder ship with, and can I get an Adams Rite cam?
Standard build comes with the 3E-C3 cam. On the options axis you can choose a Standard Cam, a Standard Spindle, or an Adams Rite MS Cam. The Adams Rite MS cam is the one you want if the cylinder is driving an MS-type deadlock rather than a conventional mortise lock body, so pick that at order time, not after the cylinder is on the shelf.
4) I need a mortise cylinder that comes complete with pins instead of less core. What else is there?
If you do not run an interchangeable core system, a conventional mortise cylinder is simpler. The Corbin Russwin 1000 Grade 1 mortise cylinder comes in a 1-1/2 inch length with an A02 straight cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway. For an interchangeable core setup that is not BEST, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder with an A01 cam sized for Schlage L9000 mortise locks.
5) Can I use the BEST 3E mortise cylinder in an exit device that takes a rim cylinder?
No. A mortise cylinder threads into the lock case and drives a cam, while a rim device needs a rim cylinder with a tailpiece. For rim applications look at the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal tailpiece cam), both 6-pin, or the Schlage 20-057 FSIC rim cylinder with a convertible tailpiece if you want interchangeable core on the rim side.
6) What is the difference between the BEST 3E Series less-core mortise cylinder and a Corbin Russwin 1000 mortise cylinder?
The BEST 3E Series 1-1/2 inch mortise cylinder ships less core, meaning the 7-pin housing arrives without a core installed so a locksmith can add the core that matches the existing keying. The Corbin Russwin 1000 Grade 1 mortise cylinder is a 1-1/2 inch length conventional cylinder supplied with an A02 straight cam. Choose the BEST 3E housing when the building is already on an interchangeable core program, and the 1000 when you want a complete conventional mortise cylinder with a straight cam.
7) Which cylinder should I use for a Schlage L9000 mortise lock instead of the BEST 3E?
The Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder with a 6-pin core and an A01 Schlage L cam, called out for Schlage L9000 mortise locks. The BEST 3E Series is a 7-pin 1-1/2 inch diameter mortise housing supplied less core with the 3E-C3 cam unless otherwise specified, so it suits 3E Series mortise lock systems rather than the Schlage L cam prep.
8) I need a rim cylinder, not a mortise cylinder. What are my options?
The BEST 3E Series mortise cylinder is a threaded mortise housing, though its ring options do include a Rim Cylinder ring. For a true rim application, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal tailpiece cam; the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Match the tailpiece orientation to the exit device or rim lock you are driving.
9) Is the BEST 3E less-core cylinder the same thing as a Schlage FSIC cylinder?
They serve the same idea but are not interchangeable. The BEST 3E Series arrives as a 1-1/2 inch diameter 7-pin mortise housing less core, accepting a BEST-style core. The Schlage 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 with a 643E aged bronze finish. Cores are not cross-compatible between the two housings, so confirm which core family the site is keyed to.
10) What cylinder works with an Adams Rite deadlock if the BEST 3E is not right for the opening?
The BEST 3E does offer an Adams Rite MS Cam option among its cam choices. If you want a purpose-built Adams Rite part instead, the 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness, and the 4024 and 4025 are cylinder pulls for MS1847 deadlock and deadlatch systems, the 4025 using through-screws. For a wood door, the 4026 five-pin cylinder pull is built for the 5017 wood door deadlock.
11) Can I use a BEST 3E mortise cylinder to rekey a key-in-knob or key-in-lever lock?
No. The BEST 3E Series is a threaded mortise cylinder housing for mortise lock bodies. For knob and lever locks, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. For a keyed deadbolt, the Ilco 1549 is a key-in-deadbolt cylinder. Falcon key-in-lever locks take the A23161-05 G cylinder, a 6-pin G keyway unit supplied keyed different with two cut keys.
12) What does the Rings choice on the BEST 3E cylinder actually change?
It sets which housing style the ring is cut for. The choices are 3E Mortise, 6-pin Mortise, 7-pin Mortise, Rim Cylinder, and Tapered Cylinder. A 7-pin mortise ring is not the same depth as a 6-pin one, so ordering the wrong ring leaves the cylinder face sitting wrong against the escutcheon. Match the ring to the housing length you are installing.
13) What finishes does the BEST 3E mortise cylinder come in to match existing trim?
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. If you are standardizing a building, the 626 satin chrome and 613 oil-rubbed are the two that most commonly match existing commercial lever trim.
14) Is the 1-1/4 inch length of the BEST 3E 7-pin cylinder the right size for my mortise lock?
The 7-pin configuration runs 1-1/4 inch in length with a 1-1/2 inch diameter face. That length is what determines whether the cam reaches the lock case hub through your door and trim thickness. If your prep needs a longer reach, the rings are the adjustment, not the housing.
15) What is a shorter mortise cylinder alternative to the 1-1/2 inch BEST 3E?
The BEST 3E Series mortise cylinder is a 1-1/2 inch diameter 7-pin unit. If the lock body prep calls for a shorter housing, the Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway. Measure from the cylinder face to the cam to confirm which length the door and lock body will take.
16) Which cylinder do I order for a residential handleset or deadbolt rather than the BEST 3E?
The BEST 3E is a commercial-style mortise cylinder housing supplied less core. For residential handlesets and deadbolts, Medeco offers the 1012040, a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. For Emtek, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and Emtek also lists the CY4 cylinder sold each.
17) If I need a Grade 1 rated mortise cylinder, how does the BEST 3E compare?
Among mortise cylinders, the Adams Rite 4036 is a five-pin unit listed Grade 1 with a 1/2 inch minimum door thickness, and the Corbin Russwin 1000 and 1070 are Grade 1 series cylinders at 1-1/2 inch and 1-1/4 inch respectively. The BEST 3E Series is a 7-pin mortise cylinder in solid brass or bronze covering door thickness from 7/8 inch to 2-1/2 inch, which gives it the widest stated door thickness range of the group.
18) Is the BEST 3E cylinder brass or is it plated pot metal?
Solid brass or bronze construction, which is why it holds up to weather and handling on exterior openings rather than pitting at the face. The finish is applied over that base material.
19) Is there installation documentation for the BEST 3E Series cylinder?
Yes, the E Series Service Manual covers it. That is the reference for core insertion, ring stacking against door thickness, and cam orientation. Worth pulling up before you set the collar height, since getting the ring count wrong is the usual reason a cylinder face sits proud.
