Corbin Russwin 606K79 57B2 626 – Frequently Asked Questions

1) Is the Corbin Russwin 606K79 a complete cylinder or just the plug?
It's the plug only. The 606K79 is a 7-pin Individual X Class cylinder plug meant for 3 inch Corbin Russwin mortise cylinders, sold as a replacement component rather than a housed cylinder with cam and keys. If you need a full mortise cylinder assembly, this is not it, and a locksmith will need to pin and install the plug into the existing shell.
2) What does the 57B2 keyway mean for keying this plug into my system?
57B2 is the factory keyway on this plug, and it only accepts keys cut on that keyway within an authorized Corbin Russwin keying system. If the rest of your building runs a different Corbin Russwin keyway, this plug won't key alike with it. Match the keyway stamped on your existing cylinders before you order.
3) If the whole mortise cylinder needs replacing rather than just the plug, what should be ordered instead of the Corbin Russwin 606K79?
The Corbin Russwin 606K79 is a 7-pin Individual X Class cylinder plug for 3 inch mortise cylinders with the 57B2 keyway - it is the plug alone, not a complete cylinder body. When the entire mortise cylinder is being replaced, a complete mortise cylinder such as the Detex MC65, a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, or the Adams Rite 4036 Grade 1 mortise cylinder with five-pin security is the item to order. Those arrive as full cylinders; the 606K79 goes into an existing Corbin Russwin cylinder shell.
4) Is a BEST interchangeable core the same thing as the Corbin Russwin 606K79 plug?
No. The 606K79 is a 7-pin X Class cylinder plug that fits inside a 3 inch Corbin Russwin mortise cylinder with 57B2 keyway. A BEST interchangeable core, such as the 1CB 150 Series core or the 1CDF drill resistant 7-pin brass 150 Series core, is a removable core that drops into BEST-style small format housings and is pulled with a control key. Both are 7-pin in the 1CDF case, but the retaining and housing systems are different, so one does not go where the other does.
5) The exit device uses a rim cylinder, not a mortise cylinder - what should be used in place of the Corbin Russwin 606K79?
The 606K79 plug is specified for 3 inch mortise cylinders, so it will not serve a rim application. Rim cylinders are a separate format: 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 cam orientation being what the device dictates.
6) Is a 7-pin X Class plug worth it over a standard 6-pin cylinder for a school or hospital?
If you run a key control program, yes. The extra pin chamber and the X Class restricted configuration give more key differs and tighter control over who can duplicate a key, which is why it shows up in education, healthcare and government buildings maintaining managed keying. For a building with no key control program and no existing Corbin Russwin system, a standard commercial cylinder is simpler to service.
7) Which cylinder suits a deadbolt instead of the Corbin Russwin 606K79 mortise plug?
The 606K79 is a 7-pin X Class plug for 3 inch mortise cylinders and is not a deadbolt part. For deadbolt work, the Kaba Ilco 1549 Series key-in-deadbolt cylinder is listed for deadbolt function, and Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
8) What is the equivalent option if the lock takes a full size interchangeable core rather than a fixed plug?
The Corbin Russwin 606K79 is a fixed 7-pin X Class plug for a 3 inch mortise cylinder. For openings built around full size interchangeable core, the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam, or the 20-057-C FSIC core in C keyway, covers that format. FSIC cores are removed with a control key; the 606K79 plug is serviced out of the cylinder body.
9) For a key-in-lever or key-in-knob lockset, is the Corbin Russwin 606K79 the right cylinder part?
No - the 606K79 is a plug for 3 inch mortise cylinders. Key-in-knob and key-in-lever locksets use their own cylinder format, covered by parts such as the Kaba Ilco 1539 Series key-in-knob / lever universal cylinder, the Kaba Ilco 1579 knob and lever cylinder for Sargent, the Kaba Ilco 1599 key-in-knob replacement cylinder, or the Falcon A23161-05 G key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys.
10) Does the Corbin Russwin 606K79 give more pin positions than the common commercial alternatives?
The 606K79 uses a 7-pin Individual X Class tumbler arrangement in the 57B2 keyway. Among comparable cylinder parts, the BEST 1CDF core is also 7-pin, while the Detex MC65 mortise cylinder and the Schlage 20-021 and 20-022 rim cylinders are 6-pin, and the BEST 1C5 core and Adams Rite 4036 mortise cylinder are 5-pin. Pin count and keyway both have to match the keying system the building already runs.
11) An aluminum storefront with an Adams Rite MS1847 deadlock needs keying - is the Corbin Russwin 606K79 usable there?
Not on its own. The 606K79 is a plug for 3 inch Corbin Russwin mortise cylinders. Storefront work on an Adams Rite MS1847 deadlock or deadlatch is served by the 4024 cylinder pull with trim plate mounting or the 4025 five pin tumbler cylinder pull with through-screws, both designed for the MS1847; for a wood door the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock.
12) What finishes does the Corbin Russwin 606K79 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the visible cylinder face on the door, since the plug is what shows through the collar.
13) Is the 606K79 plug suitable for residential doors?
It's built for commercial service. The 606K79 is a commercial-grade Corbin Russwin mortise cylinder part, and it only makes sense where a Corbin Russwin mortise lock and a managed keying system are already in place, including multi-tenant and mixed-use buildings. For a house with a standard knob or deadbolt, a key-in-knob replacement cylinder like the Kaba Ilco 1599 is the right family of part.
14) If a non-keyed cylinder is needed for a pull-side trim, is the Corbin Russwin 606K79 appropriate?
No. The 606K79 is a keyed 7-pin X Class plug built for key control in Corbin Russwin mortise cylinders. Where the opening needs a non-operating cylinder for appearance only, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the hole without a keyed function.
15) What finish choices are there on the Corbin Russwin 606K79 plug, and how do they compare with other cylinder parts?
The 606K79 X Class plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to existing mortise cylinder collars and lock trim. Among comparable cylinder parts, the Schlage 20-057-C full size interchangeable core is cataloged in 643E Aged Bronze, a darker tone that suits bronze-trim openings rather than brass or chrome.
