Corbin Russwin 606K79 27B2 626 – Frequently Asked Questions

1) Will the 606K79 plug work in a 1-1/8 inch mortise cylinder?
No. This plug is built for 3 inch mortise cylinders. A 1-1/8 inch cylinder is a different body length and takes a different plug. If you are working with a short commercial mortise cylinder, look at a complete cylinder instead, such as the Detex MC65 mortise cylinder in Schlage C keyway at 1-1/8 inches with 6 pins.
2) What does the 27B2 keyway mean for keying this plug into our existing Corbin Russwin system?
27B2 is a factory Corbin Russwin keyway. Because the plug is cut for that keyway, it will accept keys from a 27B2 system and can be pinned into an existing 27B2 masterkey hierarchy. If your building is keyed on a different Corbin Russwin keyway, this plug will not take your keys and you need the plug in your own keyway section.
3) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 606K79?
The 606K79 is a 7-pin Individual X Class plug for 3 inch mortise cylinders - a replacement part that goes into an existing cylinder shell, not a finished cylinder. If you need a whole mortise cylinder, the Adams Rite 4036 is a complete mortise cylinder with five-pin security, Grade 1, in the 4036 Series, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway. Note that both are their own keyways, so they will not key into a Corbin Russwin 27B2 system.
4) We want to be able to rekey doors without pulling cylinders. Is the 606K79 the right approach?
No. The 606K79 is a fixed 7-pin plug that has to be pinned and installed into a 3 inch mortise cylinder body. For rekeying at the door, use an interchangeable core product: the BEST 1C Series standard 5-pin cylinder core, the BEST 1CB Peaks 150 Series interchangeable core, the BEST 1CDF drill resistant patented 7-pin brass 150 Series core, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Those pull with a control key; the 606K79 does not.
5) My exit device takes a rim cylinder, not a mortise cylinder. What do I use instead of the 606K79?
The 606K79 is a mortise cylinder plug and will not serve a rim application. Rim cylinders in the same category include the Schlage 20-021 6-pin rim cylinder with vertical tailpiece cam and two keys, the Schlage 20-022 6-pin rim cylinder with horizontal tailpiece cam and two keys, and the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Confirm which cam orientation your device requires before ordering.
6) Why choose a 7-pin plug over a 6-pin for a commercial facility?
A seven pin chamber count gives you more masterkey levels to work with, which matters when a facility needs change keys, floor masters and a grand master off one system. The 606K79 is 7-pin in an X Class configuration for key control. Many commercial cylinders run 6-pin, for example the Falcon A23161-05 G key-in-lever cylinder in the G keyway or the Schlage 20-021 rim cylinder, so if your system is already built on 6 pins you should stay there rather than mix.
7) Is this an OEM Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. The 606K79 is sold as an authentic replacement component within the Corbin Russwin cylinder parts family, so tolerances match the original cylinder shell. That matters on X Class, where key control depends on factory-spec parts rather than a generic plug.
8) I manage a portfolio and want one keying standard across buildings. Is a plug like this the right approach, or should I move to interchangeable cores?
Replacing plugs means a locksmith pins each cylinder by hand, which is fine when you are keeping an established Corbin Russwin 27B2 X Class system intact. If you would rather swap keying yourself without disassembly, an interchangeable core platform is the alternative: BEST 1CB Peaks 150 Series cores, the BEST 1C 5-pin standard core, or Schlage 20-057 full size interchangeable core cylinders all let staff pull and replace a core in seconds. Converting a whole portfolio is a bigger project than a plug swap, so decide before you standardize.
9) Which model number do I give the locksmith when ordering this plug?
Call it out as Corbin Russwin 606K79 27B2, plus the finish you need (606 Satin Brass or 626 Satin Chrome). The 606K79 identifies the 7-pin X Class plug and 27B2 the keyway section, which is the pair of details a locksmith needs to pin it correctly.
10) Can I use this plug on an aluminum storefront door with an Adams Rite deadlock?
Not directly. Adams Rite MS deadlocks take their own cylinder hardware, and this is a plug for a 3 inch Corbin Russwin mortise cylinder. For a storefront application, the Adams Rite 4036 Grade 1 mortise cylinder with five-pin security is the part built for that opening, and Adams Rite cylinder pulls such as the 4024 and 4025 are made for MS1847 deadlock systems.
11) I am keying a deadbolt, not a mortise lock. Does the 606K79 fit?
It does not - it is a 7-pin plug for 3 inch mortise cylinders. For deadbolt cylinders, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
12) Can the 606K79 plug be used in a key-in-knob or key-in-lever lock?
No. The 606K79 is built for 3 inch mortise cylinder bodies. Key-in-knob and key-in-lever cylinders are a different format: the Kaba Ilco 1539 Series universal key-in-knob/lever cylinder, the Kaba Ilco 1579 for Sargent knob and lever locks, the Kaba Ilco 1599 key-in-knob replacement cylinder, and the Falcon A23161-05 G key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with two cut keys.
13) What is the difference between the Corbin Russwin 606K79 and a cylinder pull like the Adams Rite 4025?
They do different jobs. The 606K79 is the keyed plug that carries the pin stack inside a 3 inch mortise cylinder. The Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock, the 4024 is a cylinder pull with trim plate mounting for the same MS1847 deadlock and deadlatch, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock. Those are pull hardware for narrow stile and wood door deadlocks, not a mortise plug.
14) Is there a higher security or drill resistant option if the 606K79 7-pin plug is not enough protection?
The 606K79 gives 7-pin depth in the 27B2 keyway for key control within a Corbin Russwin system. If the specification calls for patented keyway control or physical attack resistance, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, 150 Series. It is an interchangeable core rather than a mortise plug, so the lock body has to accept an IC housing.
15) Our facility is standardizing on one core so any door can be rekeyed by a single tech. Does the 606K79 fit that plan?
The 606K79 supports masterkeying within a Corbin Russwin 27B2 system, but it is a fixed plug serviced at the bench. A facility standardizing on field-swappable cores would look at the BEST 1C Series standard 5-pin core, the BEST 1CB Peaks 150 Series interchangeable core, or the Schlage 20-057-C full size interchangeable core in the C keyway with a 643E Aged Bronze finish. Mixing systems means maintaining two key hierarchies, so pick one path per building.
16) What finishes does the 606K79 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder and the trim already on the door so the exposed face of the plug does not stand out against the rest of the opening.
17) I need a non-keyed filler for an opening that does not need to lock. Is there an alternative to ordering the 606K79?
Yes. The 606K79 is a working keyed plug with 7 pins and the 27B2 keyway, so it is the wrong part for a blank opening. The BEST 12E Series dummy rim cylinder with 1-5/32 inch diameter fills a rim prep without keying. For a matched appearance elsewhere on the door, note the 606K79 comes in 606 Satin Brass and 626 Satin Chrome.
18) Will the Emtek CY4 cylinder work as a substitute for the Corbin Russwin 606K79?
No. The Emtek CY4 is a cylinder sold as a part for Emtek hardware, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece for that same line. The 606K79 is a 7-pin plug dimensioned for 3 inch Corbin Russwin mortise cylinders in the 27B2 keyway, so it is not cross-compatible with Emtek trim.
