Corbin Russwin 606K76 57B2 626 – Frequently Asked Questions

1) What keyway does the Corbin Russwin 606K76 plug come in, and can I key it to my existing system?
The plug is cut for the 57B2 keyway, one of Corbin Russwin's proprietary keyways. It will accept keys from an existing 57B2 system, so it can be pinned into a master key system already running that keyway. If your building is keyed on a different Corbin Russwin section, this plug won't accept those keys.
2) I need a whole mortise cylinder, not just the plug - what should I order instead of the Corbin Russwin 606K76?
The 606K76 is a 7-pin Individual X Class plug for 2-1/4 inch mortise cylinders, so it only replaces the keyed plug inside an existing Corbin Russwin mortise cylinder assembly. If you need a complete mortise cylinder for the door, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder in the 4036 Series. Both are full cylinders rather than internal plugs, and both use their own keyways rather than the 57B2 keyway the 606K76 carries.
3) The opening uses a rim exit device, not a mortise lock - what cylinder do I use there instead?
The 606K76 plug is dimensioned for 2-1/4 inch mortise cylinders, so it does not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; both ship with 2 keys. If you want a full size interchangeable core rim cylinder, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to what the exit device requires.
4) What does 7-pin X Class mean on a Corbin Russwin cylinder plug?
X Class is Corbin Russwin's restricted key control program, and the 606K76 is the Individual X Class version, meaning it is keyed to a single specific system rather than sold open. The 7-pin tumbler stack gives more keying combinations than a 6-pin plug, which is what facilities running large master key systems need. Individual means it is supplied as a discrete plug, not part of a bulk core set.
5) Does the Corbin Russwin 606K76 plug come in a chrome finish to match my other hardware?
Two finishes are offered: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder face and the rest of the trim on the door, since the plug face is visible once it is installed.
6) I need a complete mortise cylinder, not a plug. What else does ZenSupply carry?
For a full 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 Grade 1 five-pin mortise cylinder. Note those are different keyways and different lengths, so neither will run on a Corbin Russwin 57B2 key system. If you have to stay on your existing keys, stick with Corbin Russwin cylinders in 57B2.
7) Can I use this plug in a rim cylinder or a key-in-lever cylinder?
No. It is a mortise cylinder plug, so it fits mortise cylinder shells only. For rim applications ZenSupply carries the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) 6-pin rim cylinders, and for key-in-lever work the Kaba Ilco 1539 universal knob/lever cylinder. Those are separate cylinder types, not interchangeable with a mortise plug.
8) Is this an interchangeable core I can swap without disassembling the lock?
No, and that distinction matters. The 606K76 is a plug for a conventional mortise cylinder, so servicing it means pulling the cylinder and rebuilding it. If you want tool-free core swaps across a facility, you want an interchangeable core system such as the BEST 1CB 150 Series core or the Schlage 20-057 full-size interchangeable core, which are different platforms entirely.
9) Is a BEST interchangeable core the same kind of part as the Corbin Russwin 606K76 plug?
No. The 606K76 is a keyed plug that installs inside a 2-1/4 inch Corbin Russwin mortise cylinder shell. A BEST 1CB 150 Series or 1CDF core is an interchangeable core that drops into a BEST-prepped housing as a complete unit - the 1CDF is a drill resistant patented 7-pin brass core in the 150 Series, and the BEST 1C5 is a standard 5-pin core. Interchangeable cores are removed with a control key; the 606K76 plug is serviced by disassembling the cylinder.
10) Can the 606K76 rekey a key-in-lever or key-in-knob lockset?
No. The 606K76 is a mortise cylinder plug, a replacement part for Corbin Russwin 2-1/4 inch mortise cylinder assemblies. Key-in-knob and key-in-lever locks take their own 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 locks, and the 1599 is a key-in-knob replacement cylinder. On the Falcon side, the A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway, keyed different with 2 cut keys.
11) Aluminum storefront with an Adams Rite MS1847 deadlock - is the 606K76 the right cylinder part?
No. The 606K76 plug is built for Corbin Russwin 2-1/4 inch mortise cylinders. For an MS1847 deadlock or deadlatch, Adams Rite offers the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws. For a wood door application on the 5017 wood door deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part.
12) I need a keyed cylinder for a residential deadbolt or handleset - is the 606K76 usable there?
The 606K76 is a commercial mortise cylinder plug with the 57B2 keyway, intended for Corbin Russwin mortise assemblies rather than residential deadbolts. For deadbolt and handleset retrofits, Medeco offers the 1012040, a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts; the 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts; the 1065244, a 5-pin lazy motion rim cylinder with an Emtek tailpiece; and the 1065140, a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
13) Is the 606K76 suitable for a school or hospital keying system, or is it a residential part?
It's a commercial part. Corbin Russwin lists it for commercial use, and the 7-pin X Class restricted keyway is the kind of key control schools, hospitals, offices and government buildings specify precisely because unauthorized key duplication is the problem they are managing. It is not a homeowner-grade component.
14) Do I get keys with the Corbin Russwin 606K76 plug?
Treat it as a bare cylinder component. The 606K76 is sold as a replacement plug, so plan on pinning it and cutting keys from your existing 57B2 system. By contrast, cylinders supplied as complete units often include keys, such as the Falcon A23161-05 G, which ships keyed different with two cut keys.
15) The opening only needs the look of a keyed cylinder with no operation - what is the alternative to the 606K76?
A dummy cylinder covers that. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and provides the cylinder appearance without keyed function. The 606K76 is the opposite case: a working 7-pin X Class plug with the 57B2 keyway that carries the pin stack and key control for a Corbin Russwin mortise cylinder.
16) What is the difference between the Schlage 20-057 and the 20-057-C if I am standardizing a facility away from mortise plugs?
Both are full size interchangeable core cylinders. The 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with 2 keys, while the 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E Aged Bronze finish. The Corbin Russwin 606K76 plug is a different approach to keying: it is a 7-pin plug rekeyed inside the mortise cylinder, offered in 606 Satin Brass and 626 Satin Chrome.
