Corbin Russwin 606K77 67B2 626 – Frequently Asked Questions

1) Will the 606K77 plug fit a 1-1/8 inch mortise cylinder?
No. This plug is built for 2-1/2 inch Corbin Russwin mortise cylinders. A short 1-1/8 inch mortise cylinder uses a different plug length, so ordering this one for that housing puts the wrong part in your hand. For a standard 1-1/8 inch mortise cylinder as a complete unit, the Detex MC65 is a 6-pin mortise cylinder in that size with a Schlage C keyway.
2) What keyway does the 606K77 use, and will my existing Corbin Russwin keys work?
The plug is cut for the 67B2 keyway. It will only accept keys and blanks in that Corbin Russwin profile, so it keys into an existing 67B2 system but not into a different Corbin keyway. Full model designation is 606K77 67B2.
3) If I need a complete mortise cylinder rather than just the plug, what should I order instead of the Corbin Russwin 606K77?
The 606K77 is a replacement cylinder plug only - the keyed core component that drops into a 2-1/2 inch Corbin Russwin mortise cylinder housing. If the whole cylinder body needs replacing, order a complete mortise cylinder instead. The Detex MC65 is a mortise cylinder with a Schlage C keyway in a 1-1/8 inch 6-pin format, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Both are full cylinders, so neither will carry a Corbin Russwin 67B2 keyway or interchange with an existing Corbin Russwin key system the way the 606K77 plug does.
4) What is the difference between the Corbin Russwin 606K77 plug and a BEST interchangeable core?
The 606K77 is a 7-pin X Class plug that is rekeyed and installed into a 2-1/2 inch Corbin Russwin mortise cylinder housing, so servicing it means taking the cylinder apart. A BEST interchangeable core is pulled and swapped with a control key while the housing stays in the door - the BEST 1CB is a 150 Series interchangeable core cylinder, and the 1CDF is a drill resistant patented 7-pin interchangeable core in brass. The BEST 1C 5-pin core is the standard 5-pin version. Those are BEST figure-8 cores and are not interchangeable with a Corbin Russwin mortise cylinder.
5) What does X Class mean on a Corbin Russwin 7-pin plug?
X Class is Corbin Russwin's restricted key system classification. Ordered as an Individual plug, it supports controlled key duplication, which is why facilities that police key copying spec it. The 7-pin format also gives more depth for master keying than a 6-pin plug.
6) What finishes does the 606K77 cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the trim and cylinder collar already on the door so the plug face doesn't stand out on a rekeyed opening.
7) I need an interchangeable core instead of a plug I have to pin up. What are my options?
A plug like the 606K77 gets pinned into a mortise cylinder shell, which means bench work every time you rekey. If you'd rather swap cores by hand, look at small format interchangeable core products instead: BEST offers the 1C Series 5-pin core and the 1CDF drill resistant patented 7-pin core in brass, and Schlage's 20-057 is a 6-pin full size interchangeable core with a convertible tailpiece cam.
8) Can I use the 606K77 plug in a rim cylinder or an exit device trim?
No. It's a mortise cylinder plug sized for a 2-1/2 inch Corbin Russwin mortise housing. Rim applications use a different cylinder body with a tailpiece cam. For rim work, the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal tailpiece cam) are 6-pin rim cylinders supplied with two keys.
9) Is a rim cylinder like the Schlage 20-021 a substitute for the 606K77?
No. The 606K77 is a plug for a 2-1/2 inch mortise cylinder, which threads into the lock case. The Schlage 20-021 and 20-022 are rim cylinders that mount through the door behind a rim exit device, differing from each other by vertical versus horizontal tailpiece cam. Rim and mortise cylinders use different bodies and mounting, so a rim cylinder cannot replace a mortise cylinder plug.
10) We want key-swap servicing across a facility instead of rekeying plugs. What is the alternative to the 606K77 approach?
The 606K77 is a 7-pin X Class plug that supports restricted key control within a Corbin Russwin system, but rekeying means pulling and repinning the plug. For swap-in-place servicing, full size interchangeable core hardware is the other path: the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the Schlage C keyway, 643E Aged Bronze. Moving to FSIC means standardizing on that keyway and housing rather than the Corbin Russwin 67B2 system.
11) Can I use the 606K77 plug in a knob or lever cylinder?
No. The 606K77 is dimensioned for 2-1/2 inch Corbin Russwin mortise cylinders. Key-in-knob and key-in-lever cylinders take a different body: the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys. Those serve knob and lever chassis, not mortise cylinder housings.
12) What cylinder do I use for an aluminum storefront deadlock instead of the 606K77?
The 606K77 plug is a Corbin Russwin mortise cylinder component and is not intended for narrow stile storefront deadlocks. For Adams Rite MS1847 deadlock and deadlatch systems, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws. For wood door applications on the Adams Rite 5017 wood door deadlock or deadlatch, the 4026 five pin tumbler cylinder pull applies.
13) Is this an OEM Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin cylinder component, sold as a replacement part for commercial mechanical lock systems. That matters on a keyed system where an off-tolerance plug binds in the shell.
14) Will the 606K77 work in a residential deadbolt or handleset?
No - the 606K77 is a commercial mortise cylinder plug in a 7-pin X Class configuration. Residential deadbolts and handlesets take purpose-built retrofit cylinders: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
15) I need a non-keyed filler for an opening that does not need to lock - is there an option other than the 606K77?
Yes. The 606K77 is a keyed 7-pin plug for a working Corbin Russwin mortise cylinder. Where no keying is needed, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the prep without a working cylinder. Note that it is a rim format, so it suits rim prep rather than a mortise cylinder housing.
16) The 606K77 comes in Satin Brass and Satin Chrome - what if I need a bronze finish cylinder?
The 606K77 plug is offered in 606 Satin Brass and 626 Satin Chrome. If the opening calls for a bronze tone cylinder and the key system allows a change, the Schlage 20-057-C full size interchangeable core cylinder is offered in 643E Aged Bronze with a C keyway. That is a different keyway and a different cylinder format, so it is a hardware change rather than a finish swap.
