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

1) Does the BEST 1EG mortise cylinder come with a core and keys?
No. The 1EG Series hotel shifting cam mortise cylinder ships less core, so it is the housing only. You order the interchangeable core and keys separately, matched to your existing BEST keyway and keying system. That is how most properties standardize: one core scheme across the building, housings bought as needed.
2) What is the difference between the 6-pin and 7-pin versions of the BEST 1EG cylinder?
Length, and the core depth they accept. The 6-pin configuration is 1-5/16 inches long and the 7-pin is 1-5/32 inches. Pick the one that matches the core your site is already keyed to, since a 7-pin core will not seat in a 6-pin housing.
3) What does a hotel shifting cam do on a mortise cylinder?
The shifting cam is what gives a hotel lock its key hierarchy. The cam shifts position depending on which key level turns it, so a guest key, a master, and an emergency or shutout key each produce a different lock response in the same mortise lock. On the 1EG that cam is the SC258, or another cam if you specify one. If your opening does not need that hotel key control, a standard cam cylinder is the simpler choice.
4) Will the 1-5/32 inch diameter fit a standard mortise lock cylinder hole?
Yes. The 1EG housing is 1-5/32 inches in diameter, which is the standard mortise cylinder thread diameter (1.150 inch nominal) used on commercial mortise locks. It threads into the lock case the same way any mortise cylinder does; the ring is what takes up the difference between the cylinder length and your door thickness.
5) Do I need to order a cylinder ring separately with the BEST 1EG?
No, a ring comes with it. The RP2 ring package is supplied standard on both the 6-pin and 7-pin builds unless you specify otherwise. Ring choices run 3E mortise, 6-pin mortise, 7-pin mortise, rim cylinder, and tapered cylinder, so if your escutcheon or door face needs a different collar height or a tapered profile, call it out on the order.
6) Can I get a BEST 1EG cylinder with an Adams Rite MS cam for an aluminum storefront lock?
Yes. The Adams Rite MS cam is one of the cam options, alongside the standard cam and a standard spindle. Glass front installers running an Adams Rite MS deadlock need that specific cam, so specify it on the order rather than taking the default.
7) I want an interchangeable core cylinder but my building is keyed Schlage, not BEST. What are my options?
The 1EG housing takes a BEST-format core, so it only makes sense on a BEST key system. If you are on Schlage, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is the full size interchangeable core itself in the C keyway, 643E aged bronze. For a Schlage L9000 mortise lock, the Corbin Russwin 1080 is a 1-1/2 inch 6-pin LFIC mortise cylinder built for that lock with an A01 Schlage L cam.
8) Will a Kaba Ilco 1539 or 1599 cylinder work as a substitute for the BEST 1EG?
No - those are a different cylinder format. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder and the 1599 is a key-in-knob replacement cylinder; they drop into knob and lever chassis, not into a mortise lock case. The BEST 1EG is a mortise-format cylinder with a hotel shifting cam supplied less core. If the lockset you are servicing is a key-in-lever, look at the Ilco 1579 for Sargent or the Falcon A23161-05 G key-in-lever cylinder in RU/T Series 6-pin G keyway instead.
9) What is the difference between the BEST 1EG mortise cylinder and a Corbin Russwin 1000 mortise cylinder?
The BEST 1EG Series is a hotel shifting cam mortise cylinder supplied less core, so the interchangeable core and keying are added separately by the locksmith or facility key shop. The Corbin Russwin 1000 Grade 1 mortise cylinder ships as a 1-1/2 inch length housing with an A02 straight cam. If your key system is built around BEST interchangeable cores, the 1EG keeps the opening on that system; if you are working a Corbin Russwin keyway, the 1000 is the matching housing.
10) I need an interchangeable core mortise housing but my keyway is Corbin Russwin - what is the equivalent to the BEST 1EG?
The Corbin Russwin 1080 Grade 1 Series is the closest parallel: a 1-1/2 inch LFIC mortise cylinder, 6-pin, with an A01 cloverleaf cam, listed for Schlage L9000 mortise locks. Like the BEST 1EG, it is a housing that accepts a removable core rather than a fixed-pinned cylinder. The BEST 1EG is offered in both 6-pin and 7-pin types with a hotel shifting cam.
11) Can I use the BEST 1EG cylinder in an Adams Rite MS deadlock, or do I need an Adams Rite cylinder?
The BEST 1EG can be ordered with an Adams Rite MS cam option, which is the cam profile that drives an MS-style deadlock. If you would rather use native Adams Rite hardware, the 4036 mortise cylinder is a Grade 1 five-pin unit with a 1/2 inch minimum door thickness. The tradeoff is key control: the 1EG accepts your BEST interchangeable core, while the 4036 is a conventional pinned cylinder.
12) How do I write up a BEST 1EG cylinder order so I get the right part?
Build the designation in order: series, pin count and cam, ring package, then finish. BEST's own example reads 1EF 7G4 C258 RP3 626. In practice you are choosing four things here: 6-pin or 7-pin, the cam (standard, SC258 shifting cam, or Adams Rite MS), the ring, and one of ten finishes.
13) What finishes does the BEST 1EG mortise cylinder come in for matching existing hotel door hardware?
Ten: 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 standardizing across floors, 626 satin chrome and 613 oil-rubbed bronze are the two that most commonly match existing commercial trim.
14) I need a plain mortise cylinder, not a hotel function. What should I look at instead?
If you do not need shifting cam key control, a conventional mortise cylinder is less to specify. The Corbin Russwin 1000 Grade 1 mortise cylinder comes 1-1/2 inches with an A02 straight cam, and the 1070 Grade 1 housing is a 1-1/4 inch 6-pin with an A01 cloverleaf cam. The Detex MC65 is a 1-1/8 inch 6-pin cut to the Schlage C keyway if you are keying into an existing Schlage system.
15) My opening needs a rim cylinder, not a mortise cylinder - what should I order instead of the BEST 1EG mortise configuration?
The BEST 1EG is offered with a rim cylinder ring option as well as 6-pin, 7-pin, 3E and tapered mortise rings, so the same series can cover a rim application. For a fixed-pinned rim alternative, 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; verify which orientation your exit device requires. Corbin Russwin's 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece.
16) Is a cylinder pull like the Adams Rite 4024 or 4025 an alternative to the BEST 1EG mortise cylinder?
They solve different problems. The Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both for MS1847 deadlock and deadlatch systems - they combine a door pull with a cylinder on a narrow stile aluminum door. The 4026 is the same idea for 5017 wood door deadlocks. The BEST 1EG is a cylinder only, less core, ordered with a ring package to suit the lock face.
17) I need a keyed mortise cylinder that arrives ready to install - what is a simpler option than the BEST 1EG less core?
The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in Schlage C keyway, which means it arrives as a complete pinned cylinder rather than a housing awaiting a core. The Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. The BEST 1EG stays the choice when the property runs an interchangeable core system and you want to rekey by swapping cores rather than repinning.
18) I am replacing a cylinder in a residential handleset or deadbolt - is the BEST 1EG the right part?
For a residential handleset or deadbolt, look at a rim-type retrofit cylinder instead. The Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder 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. The BEST 1EG is a mortise-format cylinder with a hotel shifting cam for mortise lock cases.
19) What is the 1EG cylinder made of, and will it hold up in a coastal or high-humidity property?
Solid brass or bronze. Both resist corrosion well, which is why they are the standard cylinder materials in hospitality and exterior openings. For salt air, the bronze finishes (611, 612, 613, 690) wear more gracefully than plated brass.
20) Is there installation documentation for the BEST 1EG cylinder?
Yes, the BEST E Series Service Manual covers this cylinder family, including core installation and cam setup. The 1EG is part of the E Series Cylinders collection, so that manual is the reference to work from rather than a generic mortise cylinder sheet.
