Corbin Russwin 606K76 67B1 626 – Frequently Asked Questions

1) Will the 606K76 plug work in my 1-1/8 inch mortise cylinder?
No. This plug is cut for 2-1/4 inch Corbin Russwin mortise cylinders, and plug length follows the cylinder length, so it won't seat correctly in a 1-1/8 inch housing. For a short 1-1/8 inch mortise cylinder you'd need a part built for that length, like the Detex MC65 1-1/8 inch six-pin mortise cylinder in Schlage C keyway.
2) What does the 67B1 keyway mean for keying this plug into my existing Corbin Russwin system?
67B1 is a specific Corbin Russwin keyway profile, so the plug only accepts key blanks cut on 67B1. If the rest of your building is keyed in a different Corbin Russwin section, this plug won't take those keys and can't be master keyed into that system. Match the keyway stamped on the cylinder you're servicing before ordering.
3) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 606K76?
The Corbin Russwin 606K76 is a 7-pin Individual X Class cylinder plug for 2-1/4" mortise cylinders with the 67B1 keyway - it is the plug itself, a service part for rebuilding an existing cylinder, not a finished cylinder housing. If you need a whole mortise cylinder to drop into the lock, the Detex MC65 is a 1-1/8" 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1 with a 1/2" minimum door thickness. Both are complete cylinders, so they come in their own keyway rather than Corbin Russwin 67B1.
4) Can I use an interchangeable core instead of re-pinning a mortise cylinder plug?
Yes, if the housing accepts a core. The Corbin Russwin 606K76 plug is pinned into a conventional 2-1/4" mortise cylinder, so rekeying means servicing the cylinder itself. An interchangeable core system lets you swap the core with a control key instead: the BEST 1CB is a Peaks 150 Series interchangeable core, the BEST 1CDF is a drill-resistant patented 7-pin brass interchangeable 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. These require IC-prepped housings rather than the conventional mortise cylinder the 606K76 rebuilds.
5) Does the 606K76 come in anything besides satin brass?
Two finishes: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder collar and lock trim already on the door, since the plug face is visible at the keyway.
6) Why choose a 7-pin plug over a 6-pin for a commercial building?
The seventh pin chamber gives you another level of masterkeying depth and tighter key control, which matters when one system has to cover many doors and sub-masters. The 606K76 is a 7-pin Individual X Class plug built for commercial mortise cylinder work. If your system runs 6-pin, don't mix, a 7-pin plug takes 7-pin keys.
7) I need to re-key mortise cylinders across a school. Is a plug like this the right approach?
It works where the mortise housings are sound and already 2-1/4 inch Corbin Russwin, because swapping plugs changes the keying without pulling locks apart further. For facilities that want tool-less rekeying at the door, an interchangeable core system is the other route, for example the BEST 1CB 150 Series interchangeable core or the Schlage 20-057 full size interchangeable core rim cylinder. Those require FSIC-prepped hardware, so they're a standardization decision rather than a drop-in for Corbin Russwin conventional cylinders.
8) Can I use the 606K76 plug in a rim cylinder or a key-in-lever cylinder?
No. It's built for 2-1/4 inch mortise cylinders only. Rim applications need a rim cylinder with a tailpiece, such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam. Key-in-lever work takes a different part again, like the Falcon A23161-05 G six-pin key-in-lever cylinder.
9) What is the difference between the Corbin Russwin 606K76 and a rim cylinder like the Schlage 20-021?
They mount in different places. The Corbin Russwin 606K76 is a plug for a 2-1/4" mortise cylinder, which threads into the lock case. The Schlage 20-021 and 20-022 are rim cylinders, mounted through the door behind rim exit device hardware; the 20-021 is 6-pin with a vertical tailpiece cam and the 20-022 is 6-pin with a horizontal tailpiece cam, each supplied with 2 keys. A rim cylinder is not a substitute for a mortise plug and will not go into a mortise lock body.
10) I need a keyed cylinder for a knob or lever, not a mortise lock - what are my options?
The Corbin Russwin 606K76 is a 7-pin plug sized for 2-1/4" mortise cylinders, so it does not serve key-in-lever hardware. For those, the Kaba Ilco 1539 Series is a key-in-knob/lever universal 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 2 cut keys.
11) Is a BEST 1C5 core the same kind of part as the Corbin Russwin 606K76 plug?
No. The BEST 1C5 is a standard 5-pin cylinder core, a complete core that seats in an interchangeable core housing. The Corbin Russwin 606K76 is a 7-pin Individual X Class plug for a conventional 2-1/4" mortise cylinder in the 67B1 keyway, and it is the rotating plug inside the cylinder rather than a removable core. The two are not interchangeable in the same housing.
12) For an Adams Rite MS1847 aluminum storefront deadlock, do I need the Corbin Russwin 606K76?
No. The 606K76 is a 7-pin plug for 2-1/4" Corbin Russwin mortise cylinders. For 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 with through-screws, both designed for use with the MS1847. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock/deadlatch.
13) I need a replacement cylinder for a residential handleset or deadbolt - is the Corbin Russwin 606K76 appropriate?
The 606K76 is a commercial mortise cylinder plug in the 67B1 keyway for 2-1/4" Corbin Russwin cylinders. For handleset and deadbolt retrofits, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
14) Is the 606K76 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. It's sold as the factory service and replacement part for compatible Corbin Russwin mortise lock cylinders, which is what keeps the pin tumbler fit and key operation matched to the original assembly.
15) What is the exact model designation to order this plug?
Order it as 606K76 with the 67B1 keyway, then state the finish, either 606 Satin Brass or 626 Satin Chrome. The keyway and the finish are both part of the ordering identity, since the same 606K76 plug is produced in more than one keyway section.
16) What finishes does the Corbin Russwin 606K76 plug come in, and can I get a matching cylinder in a darker finish?
The 606K76 is offered in 606 Satin Brass and 626 Satin Chrome. If you need a darker finish on a cylinder for the same opening, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze; note it is a C keyway FSIC core rather than a Corbin Russwin 67B1 mortise plug, so it serves IC-prepped hardware.
17) If the opening does not actually need to be keyed, is there an alternative to a working cylinder plug?
Yes. The Corbin Russwin 606K76 is a functioning 7-pin plug that provides pin tumbler engagement and key operation. Where a cylinder is needed only to fill the prep, the BEST 12E Series dummy rim cylinder with a 1-5/32" diameter is a non-keyed option, though it is a rim-style part and not a 2-1/4" mortise plug.
