Corbin Russwin 606K79 27A2 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 606K79 part, a full cylinder or just the plug?
It is the plug only, not a complete cylinder. The 606K79 is a 7-pin Individual X Class replacement plug made for 3 inch mortise cylinders, supplied with the 27A2 keyway. If you need a whole keyed mortise cylinder rather than the rotating plug assembly, this is not the part to order.
2) Does my Corbin Russwin key work if I install this plug?
Only if your keys are cut on the 27A2 keyway. The plug ships keyed to 27A2, so it accepts Corbin Russwin key blanks and key systems in that keyway. Keys from any other Corbin Russwin keyway will not enter it, so match the keyway stamped on your existing cylinder before you pin it up.
3) Is a BEST interchangeable core the same kind of part as the Corbin Russwin 606K79 plug?
No. The 606K79 is a 7-pin Individual X Class plug that goes inside a 3 inch Corbin Russwin mortise cylinder and is serviced by a locksmith. A BEST interchangeable core such as the 1C5 standard 5-pin core or the 1CB Peaks 150 Series core is a complete removable core that pulls from its housing with a control key and requires BEST figure-eight core prep in the hardware. The BEST 1CDF is a drill resistant patented 7-pin brass core in the 150 Series - same pin count as the 606K79, but a different format entirely and not installable in a Corbin Russwin mortise cylinder shell.
4) Why choose a 7-pin X Class plug instead of a standard plug?
X Class is Corbin Russwin's restricted key control program, and the 7-pin chamber count goes with it. Ordering the X Class plug keeps the cylinder inside that key control system rather than dropping it back to open keying, which matters when you are maintaining a master keyed building and want key duplication controlled.
5) I want to move to interchangeable cores instead of rebuilding plugs. What are my options?
An interchangeable core system lets you swap keying without pulling the cylinder apart, which is the opposite approach to replacing a plug. The BEST 1CB 150 Series interchangeable core, the BEST 1CDF drill resistant patented 7-pin brass core, and the Schlage 20-057 6-pin full size interchangeable core rim cylinder with convertible tailpiece cam are all cored designs. Rebuilding with the 606K79 plug makes sense when you are staying inside an existing Corbin Russwin X Class system; a core conversion means rekeying the openings involved.
6) My opening takes a rim cylinder, not a mortise cylinder - what replaces the Corbin Russwin 606K79 there?
The 606K79 plug is built for 3 inch mortise cylinders and will not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Choose by the cam orientation your exit device or rim lock requires. If the rim housing is set up for a full size interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
7) The lock is a key-in-lever, not a mortise lock - can I use the 606K79 plug?
No. The 606K79 is a mortise cylinder plug and has no application in key-in-knob or key-in-lever hardware. For those, the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder, the Ilco 1579 is a knob and lever cylinder for Sargent hardware, and the Ilco 1599 is a key-in-knob replacement cylinder. For Falcon lever hardware specifically, the Falcon A23161-05 G is a key-in-lever cylinder for RU/T Series with a 6-pin G keyway, keyed different with two cut keys. For a key-in-deadbolt, the Ilco 1549 covers that format.
8) What should I use for an aluminum storefront with an Adams Rite deadlock instead of the Corbin Russwin 606K79?
The 606K79 is an internal plug for a 3 inch Corbin Russwin mortise cylinder and is not a storefront part on its own. For Adams Rite MS1847 deadlock and deadlatch systems, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull that mounts with through-screws - pick by whether the stile can take through-bolting. For a wood door using the Adams Rite 5017 wood door deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching unit.
9) How does the Corbin Russwin 606K79 plug compare to a Schlage FSIC core for keying flexibility?
The 606K79 is a 7-pin Individual X Class plug in the Corbin Russwin 27A2 keyway, offered in 606 satin brass and 626 satin chrome, and it is rekeyed by pinning the plug itself. The Schlage 20-057-C is a full size interchangeable core in the Schlage C keyway, finished 643E aged bronze, and is swapped out as a whole core rather than repinned in place. The X Class plug keeps the opening on restricted Corbin Russwin key control; the FSIC core keys into a Schlage C system.
10) Is this a commercial part or is it fine for residential doors?
It is catalogued and built as a commercial part. Corbin Russwin lists typical use in office buildings, schools, healthcare, government buildings, multi-tenant residential, retail and hospitality, and industrial facilities. It will function on a residential door, but you are buying a commercial key control component, which usually means restricted key blanks.
11) Is the 606K79 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. It is a factory replacement component held to the original dimensional and performance specification, which is what keeps it dropping into the existing 3 inch cylinder body without fitting work.
12) I just need to fill a cylinder hole with no key function - is there an alternative to ordering the 606K79?
The 606K79 is a keyed 7-pin X Class plug and is meant to restore working key control in a 3 inch mortise cylinder. If the opening needs a cylinder appearance with no keying at all, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a rim prep without any locking function. Note that it is a rim format, so it addresses rim preps rather than mortise threads.
