Corbin Russwin 606K77 57B1 626 – Frequently Asked Questions

1) Will a 57B1 keyway plug work in my existing Corbin Russwin key system?
Only if your system is already keyed to 57B1. The 606K77 plug is cut for the proprietary 57B1 keyway, so keys from any other Corbin Russwin keyway will not enter it. Locksmiths ordering plugs for a facility key control program need the plug keyway to match the keyway on the rest of the system, otherwise the existing keys are useless in that opening.
2) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 606K77?
The 606K77 is a 7-pin Individual X Class cylinder plug for 2-1/2 inch mortise cylinders with the 57B1 keyway - it is the plug assembly that goes into an existing cylinder shell, not a whole cylinder. If the opening needs 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 Grade 1 five-pin mortise cylinder. Both are full cylinders, and both use their own keyways, so neither will key into a 57B1 system.
3) Is a BEST interchangeable core the same thing as a Corbin Russwin 606K77 plug?
No. The 606K77 is a 7-pin Individual X Class plug for a 2-1/2 inch Corbin Russwin mortise cylinder with the 57B1 keyway, and it is a replacement part that goes inside the cylinder housing. A BEST interchangeable core is a removable core pulled with a control key - the BEST 1C Series is a standard 5-pin core, the 1CB is a 150 Series interchangeable core, and the 1CDF is a drill resistant patented 7-pin brass core in the 150 Series. Those require BEST interchangeable core housings, not a Corbin Russwin mortise shell.
4) My exit device takes a rim cylinder, not a mortise cylinder. What do I use instead of the 606K77?
The 606K77 plug is built for 2-1/2 inch mortise cylinders, so it will not serve a rim application. For rim prep, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. If the facility runs full size interchangeable cores, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
5) I need a whole cylinder, not a plug. What else does ZenSupply carry for commercial mortise applications?
For a complete mortise cylinder rather than a service plug, the Adams Rite 4036 mortise cylinder is a five-pin Grade 1 unit, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Neither of those runs the Corbin Russwin 57B1 keyway, so they suit a new or standalone opening rather than an existing 57B1 key system.
6) Is this an interchangeable core, so I can swap it without pulling the cylinder?
No. The 606K77 is a conventional cylinder plug that goes into a 2-1/2 inch mortise cylinder housing during service or rekeying, not a core you pull with a control key. If you want key changes without disassembly, ZenSupply carries interchangeable cores such as the BEST 1CB 150 Series core, the BEST 1CDF drill-resistant 7-pin brass core, and the Schlage 20-057 six-pin FSIC core.
7) How do I order the right 606K77 plug for a rekey job?
You specify two things: the keyway and the finish. The model is 606K77 57B1, so the 57B1 keyway is fixed on this part, and you choose 606 Satin Brass or 626 Satin Chrome. Confirm the cylinder you are servicing is a 2-1/2 inch mortise body before you order, because that length is what the plug is cut for.
8) I need a cylinder for a Sargent or a key-in-lever lock, not a Corbin Russwin mortise. What are my options?
The 606K77 plug only suits 2-1/2 inch Corbin Russwin mortise cylinders. For key-in-knob and key-in-lever locks, the Kaba Ilco 1539 Series is a universal key-in-knob/lever cylinder, the 1579 Series is a knob and lever cylinder made for Sargent, and the 1599 is a key-in-knob replacement cylinder. For key-in-lever on Falcon, the Falcon A23161-05 G is an RU/T Series 6-pin cylinder in the G keyway, keyed different with 2 cut keys. Kaba Ilco's 1549 Series covers key-in-deadbolt applications.
9) Will the Corbin Russwin 606K77 work in an Adams Rite cylinder pull on an aluminum storefront?
No. The 606K77 is a 7-pin X Class plug sized for 2-1/2 inch Corbin Russwin mortise cylinders in the 57B1 keyway. Adams Rite cylinder pulls are their own assemblies: the 4024 mounts with a trim plate and the 4025 uses through-screws with a five pin tumbler cylinder, both for the MS1847 deadlock/deadlatch, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock/deadlatch. Specify those by the lock they serve rather than adapting a Corbin Russwin plug.
10) Why 7 pins instead of 6 on a commercial mortise cylinder plug?
The extra pin chamber is about key control and master keying depth. The 606K77 uses a 7-pin Individual X Class layout, which gives more usable key differs and tighter control over duplication than a 6-pin plug, which is why it shows up in schools, hospitals, offices, and government buildings running a managed key system.
11) Is the 606K77 rated for commercial door traffic or is it a residential part?
Commercial. It is a genuine Corbin Russwin cylinder part built to original-equipment standards for commercial mortise lock service, and the listed applications are offices, schools, healthcare, government and municipal buildings, retail, multi-tenant residential, and industrial or warehouse facilities.
12) What should I use if the door needs the look of a keyed cylinder but no actual keying?
The 606K77 is a working 7-pin X Class plug keyed in the 57B1 keyway, so it is not the part for a non-keyed opening. For a dummy application, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and fills a rim prep without keying. Note that it is a rim-format dummy, so it does not drop into a 2-1/2 inch mortise cylinder housing.
13) Does the finish choice on the Corbin Russwin 606K77 match what comparable cylinders offer?
The 606K77 plug is offered in 606 Satin Brass and 626 Satin Chrome. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze with the C keyway, a darker finish in a different keyway family - so if a facility is standardizing on satin brass or satin chrome trim, the 606K77 finishes are the ones to specify.
