BEST BES-1EG6G4-C4RP3626-PC – Frequently Asked Questions

1) What do I have to specify when ordering a BEST 1EG hotel mortise cylinder?
Three things are required on every 1EG order beyond finish and configuration: the keyway (WA, WB, WC, WD, WE, WG, WH, WK or WY), the keymark, and the marking number. You also pick 6-pin or 7-pin, the ring type (3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder or tapered cylinder), and the cam or spindle option. Without the keymark and marking number the cylinder cannot be cut to your existing system.
2) Will a BEST 1EG mortise cylinder key into the BEST system already used across my hotel?
It will if you order it in the same keyway your property already uses. The 1EG is offered in nine BEST keyways (WA, WB, WC, WD, WE, WG, WH, WK, WY), and the order also takes your keymark and marking number so the cylinder is cut to your existing masterkey system rather than keyed at random. Match the pin count too, since a 7-pin system will not accept a 6-pin cylinder core.
3) What cam comes on the BEST 1EG hotel cylinder, and can I get an Adams Rite cam instead?
Standard build is the shifting cam with the SC258 cam configuration, which is what the hotel function relies on. If you are driving an Adams Rite MS deadlock rather than a hotel mortise case, the cylinder can be ordered with an Adams Rite MS cam, and a standard spindle version is also offered. The cam has to match the lock case you are feeding, so pick that option off the lock, not off the door.
4) I need a mortise cylinder but not a hotel shifting cam one. What else is there?
If the opening is a standard commercial mortise lock, a plain cam cylinder is the simpler buy. 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 specifically, the Corbin Russwin 1080 is a 1-1/2 inch 6-pin LFIC cylinder with the A01 Schlage L cam. For an Adams Rite narrow stile deadlock, the Adams Rite 4036 five-pin mortise cylinder is the Grade 1 option.
5) Can I use the BEST 1EG in place of a rim cylinder on an exit device?
No. The 1EG is a mortise cylinder that threads into a mortise lock case and drives a cam; a rim device needs a rim cylinder with a tailpiece. For that job look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. Note that the 1EG's ring choices include a rim cylinder ring, which is a collar option only and does not turn a mortise cylinder into a rim cylinder.
6) I need a cylinder for a Schlage L9000 mortise lock instead of a BEST 1EG. What should I order?
For a Schlage L9000 mortise lock, the Corbin Russwin 1080 Grade 1 large format interchangeable core mortise cylinder in 1-1/2 inch length, 6-pin, with the A01 Schlage L cam is built for that lock body. The BEST 1EG is a 1-5/32 inch diameter hotel shifting cam mortise cylinder with the SC258 cam, so it is aimed at hospitality mortise locks rather than the L9000 cam pattern.
7) Can I use the BEST 1EG on an Adams Rite MS deadlock, or is there a better match?
The BEST 1EG can be ordered with an Adams Rite MS cam option, which suits Adams Rite MS-style lock bodies. If you want the Adams Rite part itself, the 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness. For a cylinder pull rather than a plain cylinder, the Adams Rite 4024 mounts with a trim plate and the 4025 is a five-pin cylinder pull with through-screws, both for the MS1847 deadlock and deadlatch; the 4026 is the five-pin cylinder pull for the 5017 wood door deadlock.
8) What size is the BEST 1EG mortise cylinder and how long is the 6-pin versus the 7-pin?
The 1EG hotel cylinder has a 1-5/32 inch diameter body. The 6-pin build is listed at 1-5/16 inch length and the 7-pin at 1-5/32 inch length. Check the depth of your mortise case pocket and the door thickness against that length before ordering, because a cylinder that stands proud of the trim will not let the cam swing cleanly.
9) Are collars or rings included with the BEST 1EG cylinder?
Yes. The RP2 ring package ships standard with both the 6-pin and 7-pin cylinders. Beyond that you choose the ring style on the order: 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder, or tapered cylinder. The ring is what takes up the gap between the cylinder face and the door or trim, so pick it to suit how far the cylinder sits back in the prep.
10) What is a shifting cam cylinder actually for in a hotel guest room lock?
A shifting cam cylinder is the part that makes a hotel mortise lock behave the way hospitality expects: the cam position shifts so the lock can shut out lower level keys once the guest throws the deadbolt, while the emergency key still gets in. That behavior lives in the cylinder cam, not the lock body, which is why the BEST 1EG is ordered with the SC258 cam rather than a plain straight cam. If your opening is a standard office or storeroom mortise lock with no shut-out function, you do not need a shifting cam cylinder.
11) Should I order the 6-pin or the 7-pin BEST 1EG?
Match whatever the property is already keyed to. Seven pins give a larger master keying system with more change key combinations, which is why larger properties with deep master key hierarchies run 7-pin; six pins are the more common commercial build. They are not interchangeable across one system, so if the rest of your doors are 6-pin, order 6-pin. The 1EG is built either way.
12) Is the BEST 1EG the right cylinder for a key-in-knob or key-in-lever lock?
It is not. A knob or lever lockset takes a KIK cylinder with a tailpiece, not a threaded mortise cylinder. For those openings the Kaba Ilco 1539 universal key-in-knob/lever cylinder covers a wide range of locksets, the 1579 is the version for Sargent knobs and levers, and the Falcon A23161-05 G is a 6-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys. Reserve the 1EG for mortise lock cases.
13) What is the difference between the BEST 1EG premium core cylinder and a Schlage FSIC core?
The BEST 1EG is a complete hotel shifting cam mortise cylinder with a premium core, sold with a keyway selection and the RP2 ring package. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in C keyway with a 643E aged bronze finish. Those are rim-side and core-only parts, so they do not thread into a mortise lock case the way the 1EG does.
14) What cylinder replaces the one in a residential deadbolt or handleset rather than a hotel mortise lock?
For deadbolts and handlesets, look at the Medeco rim-type options: 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, and the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece. The Kaba Ilco 1549 is a key-in-deadbolt cylinder. The BEST 1EG is a mortise cylinder with a hotel shifting cam, so it belongs in a mortise lock case rather than a deadbolt body.
15) Is there a simpler mortise cylinder than the BEST 1EG if I just need a Schlage C keyway 6-pin?
The Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, commercial grade, which is a plain mortise cylinder without a shifting cam. The BEST 1EG is a 1-5/32 inch diameter shifting cam cylinder offered in 6-pin and 7-pin types with BEST keyways WA, WB, WC, WD, WE, WG, WH, WK and WY, so the two are keyed into different key systems and use different cam behavior.
16) Which cylinder should I order for an Emtek or Arrow JL interconnected lock instead of the BEST 1EG?
For an Emtek opening, the Emtek CY4 cylinder is the brand-matched part, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock as well as Emtek handleset and deadbolt outside cylinder use. The BEST 1EG is a hotel shifting cam mortise cylinder ordered with a keyway, keymark and marking number, which makes it a fit for keyed mortise lock systems rather than those interconnected and handleset chassis.
17) What finishes does the BEST 1EG hotel cylinder come in so it matches my 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. Those are standard BHMA finish numbers, so matching by number to the escutcheons already on your doors is more reliable than matching by name.
18) What is the BEST 1EG cylinder made of, and will it hold up in a coastal or high-humidity property?
Body material is solid brass or bronze, which is the usual choice where corrosion resistance matters. That construction is why these get specified for guest rooms, dorms, healthcare patient rooms and multi-family units that see constant key traffic.
19) Is there service documentation for the BEST E Series cylinders?
Yes. BEST publishes an E Series Service Manual covering these cylinders, hosted at zensupply.com/content/pdf/best/E-Series-Service-Manual.pdf. It is the reference to use for core removal, pinning and cam changes alongside the instructions for the mortise lock case the cylinder is going into.
