Corbin Russwin 606K79 77B2 626 – Frequently Asked Questions

1) Does the 77B2 keyway mean it can be keyed into our existing Corbin Russwin master key system?
The 77B2 keyway ties it into the Corbin Russwin keying system, so it can be pinned to a master key or key control program running on that keyway. Keys cut on a different Corbin Russwin section will not enter it. For a facility standardizing on one section, matching the keyway across every cylinder is what keeps the system intact.
2) Can I use a Schlage 20-021 rim cylinder in place of the Corbin Russwin 606K79 plug?
No. The Corbin Russwin 606K79 is a 7-pin Individual X Class plug, a replacement component that goes inside a 3 inch Corbin Russwin mortise cylinder on the 77B2 keyway. The Schlage 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, which mounts through the door behind rim-mounted hardware. If the existing hardware takes a mortise cylinder body and only the plug is being replaced or re-keyed, the 606K79 is the part; if a whole rim cylinder is needed, the 20-021 is a cylinder assembly rather than an internal plug.
3) I need a complete mortise cylinder, not just a plug - what should I order instead of the 606K79?
The Corbin Russwin 606K79 is only the 7-pin plug for a 3 inch mortise cylinder on the 77B2 keyway, so it will not serve on its own if the cylinder body is missing or damaged. For a complete mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder cut to the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 series. Both are standalone cylinders on their own keyways rather than components of a Corbin Russwin 77B2 keying program.
4) My cylinder is in a knob or lever, not a mortise lock - is the 606K79 the right plug?
No. The Corbin Russwin 606K79 plug is engineered for 3 inch mortise cylinders on the 77B2 keyway. Key-in-knob and key-in-lever hardware uses a different cylinder format: the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent hardware, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder on the RU/T series 6-pin G keyway, keyed different with 2 cut keys. Confirm whether the lock body accepts a threaded mortise cylinder before ordering the 606K79.
5) We want interchangeable cores so we can re-key without pulling hardware. Is this plug the right approach?
No. The 606K79 is a fixed plug that a locksmith swaps and pins inside the mortise cylinder. If the goal is re-keying without disassembly, look at an interchangeable core system instead, such as the BEST 1CB 150 Series core or the BEST 1CDF drill resistant 7-pin brass core. Those pull with a control key in seconds.
6) Will a 7-pin plug give better key control than the 6-pin cylinders we have now?
The 7-pin X Class arrangement is built for higher key control and security than a standard configuration, which is why it shows up in government, healthcare and multi-tenant office keying programs. It does mean keys, pins and the rest of the system have to be 7-pin on the 77B2 section; you cannot mix a 6-pin key into it.
7) How does the 606K79 plug differ from an interchangeable core like the BEST 1CDF?
The Corbin Russwin 606K79 is a 7-pin Individual X Class plug that is fitted inside a 3 inch mortise cylinder on the 77B2 keyway, so changing keying means working the cylinder itself. The BEST 1CDF is a 7-pin interchangeable core in the 150 series, drill resistant and on a preferred patented keyway, and the BEST 1CB is a 150 series interchangeable core in the 1CB series; interchangeable cores are pulled and swapped with a control key rather than re-pinned in place. Both approaches give 7-pin architecture, but they belong to different keying systems and are not cross-usable.
8) What do I use for a deadbolt cylinder rather than the Corbin Russwin 606K79?
The 606K79 is a mortise cylinder plug on the Corbin Russwin 77B2 keyway and is not a deadbolt cylinder. For deadbolt applications the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, while the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Those are complete cylinders on their own keyways, so they will not key alike to a Corbin Russwin 77B2 system.
9) Do keys come with the Corbin Russwin 606K79 plug?
Treat it as a bare plug. It is supplied as an OEM replacement component for a mortise cylinder assembly, to be pinned and keyed by your locksmith to your existing 77B2 system. Cylinders that ship with cut keys, like the Schlage 20-021 rim cylinder, are a different kind of purchase.
10) Is this a residential deadbolt part or commercial hardware?
Commercial. The 606K79 is a genuine Corbin Russwin replacement part for mortise cylinder assemblies in commercial buildings, offices, schools, healthcare and hospitality properties running Corbin Russwin keying programs. It is not sold as a residential deadbolt cylinder.
11) Will the 606K79 work with an Adams Rite MS1847 cylinder pull?
Those are separate systems. The Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both made for the Adams Rite MS1847 deadlock/deadlatch, and the 4026 five pin tumbler pull is for the Adams Rite 5017 wood door deadlock/deadlatch. The Corbin Russwin 606K79 is a 7-pin Individual X Class plug for a 3 inch Corbin Russwin mortise cylinder on the 77B2 keyway, intended for re-keying and maintaining Corbin Russwin mortise cylinder assemblies.
12) I only need a non-functional cylinder for appearance - is the 606K79 overkill?
The Corbin Russwin 606K79 is a keyed 7-pin Individual X Class plug intended for live re-keying and maintenance of 3 inch mortise cylinders on the 77B2 keyway, so it is not the part for a decorative opening. The BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills a cylinder hole without operating hardware, and the Emtek CY4 cylinder is sold as a single parts-series cylinder. Choose the 606K79 when the plug has to key into an existing Corbin Russwin program.
13) Is a BEST 1C5 core a lower-pin alternative to the 606K79?
They are not interchangeable. The BEST 1C5 is a standard 5-pin cylinder core from the standard and premium cores line, pulled and replaced as a core. The Corbin Russwin 606K79 carries 7-pin Individual X Class architecture for enhanced key control and is machined to seat in a 3 inch Corbin Russwin mortise cylinder on the 77B2 keyway, in satin brass or satin chrome. The pin count and the host cylinder both differ, so the choice follows whichever keying system the facility already runs.
