BEST BES-3E74C4RP3626-SC – Frequently Asked Questions

1) Will the BEST 3E mortise cylinder work on my door thickness?
The 3E Series mortise cylinder covers doors from 7/8 inch up to 2-1/2 inch thick. The range is handled with the included RP4 ring package, which contains 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 proud of it.
2) What cam comes on the BEST 3E cylinder, and can I get an Adams Rite cam instead?
Standard supply is the 3E-C3 cam, which is what BEST mortise locks take. If you're cylinder-pulling an aluminum storefront MS deadlock, order the Adams Rite MS cam option instead. A standard spindle option is also offered. Pick the cam to match the lock body, not the door, because a BEST cam will not drive an MS bolt.
3) Is this BEST cylinder for interchangeable cores or is it a standard keyed cylinder?
It's a standard core cylinder, not an IC housing. The 7-pin plug is keyed and pinned in the cylinder itself, so there is no figure-eight core to pull. If you're running a small format interchangeable core system and want to swap cores with a control key, this is the wrong part for that program.
4) What do I have to specify when ordering a BEST 3E mortise cylinder?
Three things beyond finish and cam: keyway, keymark, and marking number, and all three are required. Keyway choices are A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD and TE. The keymark and marking number are how the cylinder gets pinned into your existing BEST key system, so pull them off a key or your keying schedule before you order.
5) Will a BEST 3E cylinder key into the rest of my building's BEST locks?
Yes, as long as you order it in the same keyway and under the same keymark as the existing cylinders. The 7-pin format gives a deeper master keying tree than a 6-pin system, so it can sit under an existing grand master without burning combinations. Supply the marking number from your keying records and it comes pinned to that system rather than keyed different.
6) I need a mortise cylinder but I'm not on a BEST key system. What else is there?
A BEST 3E is only worth ordering if you're keying into a BEST keyway. On another system, the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch with an A02 straight cam is the conventional equivalent, and the 1070 Grade 1 housing in 1-1/4 inch 6-pin with an A01 cloverleaf cam covers shorter preps. If the lock is a Schlage L9000, the Corbin Russwin 1080 1-1/2 inch LFIC 6-pin with the A01 Schlage L cam is built for that lock.
7) My storefront door has an Adams Rite MS deadlock. Should I use this or an Adams Rite cylinder?
Either route works. Order the 3E with the Adams Rite MS cam option if you want the opening on your BEST key system. If you'd rather stay native to the lock, the Adams Rite 4036 five-pin mortise cylinder is Grade 1 and fits down to a 1/2 inch minimum thickness, and the 4024 and 4025 cylinder pulls are built specifically for the MS1847 deadlock and deadlatch.
8) My opening takes a rim cylinder, not a mortise cylinder - what do I order?
A mortise cylinder like the BEST 3E threads into a mortise lock body and drives it through a cam; a rim cylinder mounts to the inside face of the door and drives an exit device or rim lock through a tailpiece, so the two are not interchangeable. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim 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 and length to the device you are feeding.
9) I need a replacement cylinder for a key-in-knob or key-in-lever lock, not a mortise lock - what should I use?
The BEST 3E Series is a mortise cylinder and threads into a mortise lock body, so it will not drop into a cylindrical knob or lever. For those, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder made for Sargent, and the 1599 is a key-in-knob replacement cylinder. Falcon offers the A23161-05 G key in lever cylinder, a 6-pin G keyway for RU and T Series, keyed different with two cut keys. For a keyed deadbolt, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
10) What is the closest equivalent to a BEST 3E mortise cylinder from another manufacturer?
For a 1-1/2 inch mortise cylinder in another line, the Corbin Russwin 1000 Series mortise cylinder is the nearest match at 1-1/2 inch length with an A02 straight cam. The BEST 3E Series standard core mortise cylinder is also 1-1/2 inch diameter, 7-pin, solid brass, and ships with the 3E-C3 cam and the RP4 ring package. The difference to settle before ordering is the cam: the 3E-C3 is made to drive BEST mortise lock systems, while the Corbin Russwin 1000 uses the A02 straight cam, so the cylinder has to be matched to the mortise lock body already in the door.
11) I need an interchangeable core cylinder instead of a standard core - what should I look at?
The BEST 3E Series cylinder covered here is a standard core mortise cylinder, so the core is not removable with a control key. If the job calls for interchangeable core, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the Schlage 20-057-C is the FSIC core itself in the C keyway with a 643E aged bronze finish. The Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with an A01 cloverleaf cam - that one keeps the mortise format while giving you a removable core.
12) Will a BEST 3E cylinder work in an Adams Rite narrow stile deadlock?
The BEST 3E Series is offered with an Adams Rite MS cam as a cam option alongside the standard cam, which is what a narrow stile MS deadlock needs to be driven. If you would rather buy the cylinder native to that hardware, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness. Note the pin count difference - the 3E is 7-pin, the 4036 is five-pin - which matters if you are folding the opening into an existing 7-pin master key system.
13) Which cylinder matches a Schlage L9000 mortise lock - can I use the BEST 3E?
The BEST 3E ships with the 3E-C3 cam for BEST mortise lock systems and is also offered with an Adams Rite MS cam option. For a Schlage L9000 mortise lock specifically, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, called out for Schlage L9000 mortise locks with the A01 Schlage L cam. Cam shape is what decides this, so verify the cam against the lock body rather than the cylinder diameter alone.
14) What ring types are available for the BEST 3E cylinder?
Ring selection covers 3E Mortise, 6-pin Mortise, 7-pin Mortise, Rim Cylinder and Tapered Cylinder. The ring is what sets the cylinder face at the right projection through the lock trim, so match it to the prep you're dropping into. Tapered rings are the ones used where the trim has a beveled collar rather than a flat escutcheon.
15) 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. For a property running standard commercial trim, 626 and 630-family satin finishes are the usual match; 613 is the one to pick against oil-rubbed bronze lever trim.
16) What size is the BEST 3E cylinder and will it fit a standard mortise lock pocket?
It's a 1-1/2 inch diameter cylinder with a 1-1/4 inch length in the 7-pin configuration. That's the conventional mortise cylinder thread size, so it screws into a standard mortise lock case cylinder hole. Length plus ring stack is what you adjust to get the face flush on thicker doors.
17) What is the difference between the BEST 3E mortise cylinder and an Adams Rite cylinder pull?
They do different jobs. The BEST 3E is a mortise cylinder only - the keyed plug and housing that screws into a lock body. An Adams Rite cylinder pull combines the cylinder with a door pull: the 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock. If the door already has a pull and you only need the keyed cylinder replaced, the 3E is the part; if there is no pull, the 4024, 4025 or 4026 covers both.
18) Is there a shorter mortise cylinder than the 1-1/2 inch BEST 3E for a thinner door or shallow prep?
The BEST 3E covered here is 1-1/2 inch diameter with a 1-1/4 inch length in the 7-pin configuration and accommodates doors 7/8 inch to 2-1/2 inch thick, with the RP4 ring package of 3E-R2 at 1/8 inch and 3E-R4 at 1/4 inch to fine-tune projection. If you need a shorter housing outright, 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 in the Schlage C keyway. Both are 6-pin, so confirm the keying system before substituting.
19) Can I use a BEST 3E cylinder on a residential handleset or Kwikset deadbolt?
The BEST 3E is a mortise cylinder driven by a cam and is intended for compatible BEST mortise lock systems, so it is not the part for a residential handleset or a cylindrical deadbolt. Medeco covers those retrofits: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Emtek also lists the CY4 cylinder sold each.
20) If I am standardizing a facility on one keyway, does the BEST 3E give more keying flexibility than the comparable cylinders?
The BEST 3E Series standard core mortise cylinder is 7-pin and is ordered by keyway across a 20-keyway range from A through TE, plus DD, TB, TC and TD, with keymark and marking number specified at order. The comparable mortise and rim cylinders sit at lower pin counts and fixed keyways: the Detex MC65 is 6-pin in Schlage C, the Corbin Russwin 1070 and 1080 are 6-pin, the Schlage 20-057-C core is C keyway, and the Adams Rite 4036 is five-pin. For a facility keying to a 7-pin BEST system, the 3E stays inside that system where the 6-pin and 5-pin cylinders would need their own.
21) What is the BEST 3E cylinder made of, and will it hold up outdoors?
Body material is solid brass or bronze, which resists corrosion better than plated pot metal on an exterior opening. For doors that see weather directly, add the 3E-7B4 dust cover to keep water and grit out of the keyway.
22) Where do I find the service instructions for the BEST E Series cylinders?
BEST publishes an E Series Service Manual covering the cylinder family, and it's the document to work from for pinning, ring stacking and cam changes. Because this is a replacement cylinder going into an existing lock, also check the parent lock's installation instructions for the cam and prep it expects before you pin anything.
