Corbin Russwin 606K79 27B1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 606K79 plug, and is it a complete cylinder?
It is the plug only, the rotating pin-tumbler core that sits inside a 3 inch Corbin Russwin mortise cylinder shell. It is sold as a replacement component, not a finished cylinder, so you do not get a housing, cam, or screws with it. If your existing mortise cylinder shell is sound and you only need to change or restore the keying, this is the part. If you need a whole cylinder assembly, order a mortise cylinder instead.
2) Will the 606K79 plug work in a 1-1/8 inch mortise cylinder?
No. The 606K79 is built for 3 inch Corbin Russwin mortise cylinders. Dropping it into a standard 1-1/8 inch mortise cylinder is not the intended application. For a short commercial mortise cylinder, look at a complete unit such as the Detex MC65, a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway.
3) What keyway does the Corbin Russwin 606K79 plug come in, and can it be keyed into our existing master key system?
The plug is cut for the 27B1 keyway, one of the Corbin Russwin restricted profiles. If your building is already keyed in 27B1, this plug can be pinned into that existing master key hierarchy by your locksmith. If your other cylinders are a different Corbin Russwin section, or a Schlage or Sargent keyway, this plug will not accept those keys and you need the matching section instead.
4) If I want to rekey without pulling the cylinder apart, what should I use instead of the 606K79 plug?
The 606K79 plug is rekeyed at the bench as a cylinder component. For keying changes made at the door, interchangeable-core hardware is the alternative: the BEST 1CB is a 150 series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core 7-pin brass core in the 150 series, and the Schlage 20-057-C is a full size interchangeable core in the C keyway with a 643E Aged Bronze finish.
5) Why a 7-pin plug instead of 6-pin, for a school or hospital keying system?
The extra chamber is about key control and master keying depth. A 7-pin X Class plug gives a locksmith more room to build master, grand master, and change key levels on a restricted section, which is what large facilities with many tenants or departments need. Six-pin cylinders, like the Detex MC65 or the Schlage 20-021 rim cylinder, are fine for smaller systems but give you fewer usable combinations under a master.
6) What finishes is the 606K79 plug available in, and will it match our existing trim?
Two finishes: 606 Satin Brass and 626 Satin Chrome. Pick 606 to blend with brass or bronze-toned mortise cylinders and escutcheons, and 626 where the door hardware is satin chrome or brushed nickel. Since the plug face is the visible part once installed in the cylinder, matching it to the surrounding cylinder collar is what keeps the opening looking consistent.
7) Do keys come with the Corbin Russwin 606K79 plug?
Cut keys are not part of the 606K79 offering. It is a bare plug meant to be pinned to your existing 27B1 system by a locksmith, who supplies the keys. If you need a cylinder that ships with keys already, a complete unit like the Schlage 20-022 rim cylinder is supplied with two keys.
8) What is the closest 7-pin alternative to the Corbin Russwin 606K79?
The 606K79 is a 7-pin plug built for the Corbin Russwin 27B1 keyway, so it only keys into Corbin Russwin systems. The other 7-pin option in commercial cylinders is the BEST 1CDF drill-resistant patented interchangeable core, a 7-pin brass 150 series core; BEST's 1C series standard core is a 5-pin core by comparison. Neither shares the 27B1 keyway, so they change the key system rather than match it.
9) Will a rim cylinder work in place of the Corbin Russwin 606K79?
No. The 606K79 is a plug for a 3 inch mortise cylinder. Rim cylinders mount through the door face and drive a tailpiece: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, and the BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter. None of those fit a mortise cylinder body.
10) I need a cylinder for a knob or lever lock, not a mortise cylinder plug - what are my options?
The 606K79 plug serves 3 inch mortise cylinders. For key-in-knob and key-in-lever bodies, the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, keyed different with two cut keys.
11) For a narrow stile aluminum door deadlock, is the 606K79 the right cylinder part?
The 606K79 is a plug for a 3 inch Corbin Russwin mortise cylinder and is not tied to a specific lock body. For Adams Rite narrow stile deadlocks, the parts are matched to the lock: the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five-pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five-pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch.
12) Is this a residential or commercial part?
Commercial. The 606K79 is specified for commercial door hardware: office buildings, schools, healthcare, government, retail, warehouse, and multi-tenant residential. It is not a residential-grade retrofit part. For a house or a light-duty handleset, a Kaba Ilco 1599 key-in-knob replacement cylinder or a Medeco 1075127 rim-type cylinder for handlesets and deadbolts is the more appropriate direction.
13) Is the 606K79 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin, from their cylinder parts line, so it drops into Corbin Russwin mortise cylinder assemblies without modification. That matters on a restricted keyway like 27B1, where aftermarket plugs often will not accept the factory key blanks or pin to the same specification.
14) What is the simpler option if I do not need X Class key control?
The 606K79 is a 7-pin Individual X Class plug intended for restricted key control in Corbin Russwin systems. Where standard keying is acceptable, the BEST 1C series standard 5-pin cylinder core is a plain core, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam supplied with two keys.
