Corbin Russwin 606K79 27A1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 606K79, a complete cylinder or just the plug?
It is the plug only, not a finished cylinder. The 606K79 is a 7-pin Individual X Class replacement plug made to go into a 3 inch Corbin Russwin mortise cylinder shell. If you need a whole cylinder to drop into a lock, this is not that part; it is the serviceable core component a locksmith swaps or re-pins during cylinder work.
2) Do I need 27A1 keyway blanks to key this plug?
Yes. The plug is cut for the Corbin Russwin 27A1 keyway, so keys must be on 27A1 blanks. If the rest of your building runs on a different Corbin Russwin keyway, this plug will not accept those keys and you would be creating a second key system.
3) If I need a complete mortise cylinder instead of just a replacement plug, what should I order?
The Corbin Russwin 606K79 27A1 is a 7-pin individual X Class plug, a replacement part for servicing a 3 inch Corbin Russwin mortise cylinder rather than a whole cylinder. If the job calls for a complete mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1. Both are full cylinders you install in the lock case; the 606K79 only rebuilds an existing Corbin Russwin cylinder body.
4) Is a BEST interchangeable core an equivalent to the Corbin Russwin 606K79 plug?
No. The 606K79 27A1 is a pinned plug that is fitted inside a Corbin Russwin 3 inch mortise cylinder housing during service or re-keying. A BEST 1CB 150 Series or 1CDF drill-resistant 7-pin brass core is an interchangeable core that drops into a BEST-prepped housing as a unit and is removed with a control key. Both are 7-pin class parts in the 1CDF case, but the mounting systems are not interchangeable; choose the core route only if the hardware is already prepped for BEST interchangeable cores.
5) My opening uses a rim exit device, not a mortise lock. Is the 606K79 the right part?
No. The 606K79 27A1 plug is built for 3 inch mortise cylinder applications. For rim-prepped hardware, 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; the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Each ships with 2 keys. Confirm cam orientation against your device before ordering.
6) What do I use instead if the cylinder is in a key-in-knob or key-in-lever lockset?
The 606K79 27A1 plug serves Corbin Russwin 3 inch mortise cylinders, not knob or lever cylinders. For key-in-knob and key-in-lever hardware, the Kaba Ilco 1539 Series is a universal key-in-knob/lever cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with 2 cut keys.
7) I need a cylinder pull for an aluminum storefront deadlock. Does the 606K79 fit that?
No. The 606K79 27A1 is a plug for Corbin Russwin 3 inch mortise cylinders and carries no pull trim. For Adams Rite MS1847 deadlock and deadlatch systems, 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. For wood doors using the Adams Rite 5017 deadlock or deadlatch, the 4026 is the five pin tumbler cylinder pull.
8) Does the keyway on the 606K79 restrict which of these alternatives I can key alike?
Yes. The 606K79 is supplied in the 27A1 keyway, a factory-specified Corbin Russwin profile matched to its own key blanks. Peers keyed in other profiles will not key alike with it: the Detex MC65 mortise cylinder uses the Schlage C keyway, the Schlage 20-057-C full size interchangeable core is C keyway, and the Falcon A23161-05 G uses the 6-pin G keyway. Keep the 27A1 plug where the facility system is already built on that profile.
9) Why 7 pins instead of 6 on this Corbin Russwin plug?
The 7-pin tumbler layout gives more key combinations than a standard 5- or 6-pin plug, which matters when you are building out a large master key system and need depth in the hierarchy. It also means the plug will only take 7-pin keys, so it has to match the rest of the system you are servicing.
10) For a deadbolt cylinder, is there an alternative to the Corbin Russwin plug?
Yes, but they are different parts. The 606K79 27A1 is a mortise cylinder plug. For deadbolt service, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and 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.
11) What is a simpler lower-pin-count option if I do not need 7-pin key control?
The 606K79 27A1 uses a 7-pin tumbler design with X Class restricted key control, which suits facilities running managed key duplication programs. Where that level of key control is not required, the BEST 1C standard 5-pin cylinder core and the Adams Rite 4036 five-pin mortise cylinder are lower pin count options. Note these are complete cylinders or cores rather than service plugs for a Corbin Russwin body.
12) What looks like a substitute for this plug but will not key into a system?
The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and the appearance of a cylinder, but it is a dummy with no working key function, so it cannot replace the keyed 606K79 27A1 plug. The Emtek CY4 cylinder is a residential-type part sold each. The 606K79 is a commercial X Class 7-pin plug in the 27A1 keyway intended for keyed systems and re-keying work.
13) What finishes does the Corbin Russwin 606K79 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder ring and the escutcheon or rose already on the door, since the plug face is the visible part once the cylinder is installed.
14) I need to match a satin chrome trim rather than brass. What are my options?
The 606K79 plug is offered in 606 Satin Brass and 626 Satin Chrome, so the satin chrome finish is available on the part itself. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze if you are matching darker trim on a rim-prepped opening instead.
