Corbin Russwin 606K76 27B2 626 – Frequently Asked Questions

1) Will a 606K76 plug work in a 1-1/8 inch mortise cylinder?
No. This plug is sized for 2-1/4 inch Corbin Russwin mortise cylinders only. A shorter cylinder body, like the 1-1/8 inch size used on many exit devices, takes a shorter plug and this one will not seat. For a 1-1/8 inch mortise cylinder in a different keyway, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C.
2) Does the 27B2 keyway on this Corbin Russwin plug mean it will work in our existing master key system?
Only if your system is already built on the Corbin Russwin 27B2 keyway. The plug is factory cut for 27B2, so it drops into an existing 27B2 keying and master key program and can be pinned by your locksmith to the change key and master. A cylinder keyed to any other Corbin Russwin section will not accept 27B2 keys, so check the keyway stamp on the cylinder you are servicing before ordering.
3) I need a whole mortise cylinder, not just a plug — what should I order instead of the Corbin Russwin 606K76?
The Corbin Russwin 606K76 27B2 is a 7-pin plug, a component that goes inside a 2-1/4 inch mortise cylinder shell, so it will not serve as a complete cylinder on its own. For a complete mortise cylinder, the Adams Rite 4036 is a mortise cylinder with five-pin security in the 4036 Series, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway. Choose the complete cylinder when the existing shell is damaged or missing; choose the 606K76 plug when the shell stays in the lock and only the keyed plug is being replaced.
4) My Corbin Russwin opening uses a rim device, not a mortise cylinder — what do I use there?
The 606K76 27B2 plug is sized for 2-1/4 inch mortise cylinders, so it does not fit a rim application. For rim cylinders, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Match the cam orientation to the exit device you are servicing.
5) Is a BEST interchangeable core the same thing as the Corbin Russwin 606K76 plug?
They are different parts. The 606K76 27B2 is an individual X Class 7-pin plug for a 2-1/4 inch Corbin Russwin mortise cylinder, keyed to the 27B2 keyway, and it is pinned and installed as part of a mortise cylinder assembly. The BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, 150 Series, and the BEST 1C5 is a standard 5-pin cylinder core; interchangeable cores are removed and swapped with a control key rather than pinned into a mortise shell. Order the 606K76 for Corbin Russwin mortise cylinder service and a BEST core only if the housing is built for interchangeable cores.
6) Will the Corbin Russwin 606K76 plug work in a key-in-lever or key-in-knob lock?
No. The 606K76 27B2 plug is built for 2-1/4 inch mortise cylinders used in commercial mortise lock assemblies. Key-in-knob and key-in-lever bodies take a different cylinder format: the Falcon A23161-05 G is a key-in-lever cylinder on a 6-pin G keyway supplied keyed different with two cut keys, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. For Sargent knob and lever hardware the Kaba Ilco 1579 is the cylinder for that application.
7) We use interchangeable cores elsewhere. Can this Corbin Russwin plug be used as an IC core?
No. The 606K76 is a conventional plug that goes inside a fixed 2-1/4 inch mortise cylinder body, not a removable core. If you want core-swap re-keying instead, that calls for an interchangeable core product, such as the BEST 1CB 150 Series interchangeable core or the BEST 1CDF 7-pin drill resistant core, or a full size interchangeable core cylinder like the Schlage 20-057.
8) Does the 606K76 plug come with keys?
It is sold as the plug itself in the 27B2 keyway, a genuine Corbin Russwin cylinder component for rebuilding a 2-1/4 inch mortise cylinder. Pins, springs and keys are pinned and cut by whoever is servicing the system to match your existing 27B2 change and master keys, so plan on your locksmith supplying those. If you want a cylinder that ships with cut keys, the Falcon A23161-05 G is supplied keyed different with 2 cut keys.
9) We only need 5-pin or 6-pin keying, not 7-pin — what are the simpler alternatives?
The Corbin Russwin 606K76 27B2 is a 7-pin X Class plug, a configuration used where deeper masterkeying levels and factory key control matter. If a shallower pin stack suits the system, the BEST 1C5 is a standard 5-pin cylinder core, the Adams Rite 4036 mortise cylinder is five-pin, and the Detex MC65 is a 6-pin mortise cylinder on the Schlage C keyway. Note that these are different keyways and core formats, so they will not key into an existing Corbin Russwin 27B2 system.
10) We are re-keying deadbolts, not mortise locks — is the 606K76 the right part?
The 606K76 27B2 plug is a mortise cylinder component for commercial mortise lock service, not a deadbolt cylinder. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Kaba Ilco 1539 key-in-knob/lever universal cylinder is also listed for deadbolt function. On residential handlesets and deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
11) Is the 606K76 plug what I need for an Adams Rite cylinder pull on a storefront door?
No. The 606K76 27B2 is a plug for a 2-1/4 inch Corbin Russwin mortise cylinder. Adams Rite cylinder pulls are separate assemblies tied to specific deadlocks: the 4024 cylinder pull mounts with a trim plate and is designed for the Adams Rite MS1847 deadlock/deadlatch, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 five pin tumbler cylinder pull is for the Adams Rite 5017 wood door deadlock/deadlatch. Select by the deadlock already in the door and, on the 4024 versus 4025, by whether you are mounting to a trim plate or through-bolting.
12) I need a non-keyed part for a pull-side trim where no key operation is required — what takes the place of the 606K76?
The 606K76 27B2 is a keyed plug pinned to the 27B2 keyway for working mortise cylinders, so it is the wrong choice where no key function is wanted. The BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a cylinder opening on a rim application without key operation. Keep the 606K76 for openings that must remain keyed into the Corbin Russwin master key program.
13) Is this part suitable for a commercial building or is it a residential repair part?
Commercial. The 606K76 plug is a service part for commercial mechanical mortise lock assemblies, the kind used in offices, schools, hospitals, municipal buildings and multi-tenant properties where key control has to be maintained during re-keying. Facilities running Corbin Russwin mortise hardware use it to rebuild cylinders rather than replace whole locks.
14) What finishes can I match to the Corbin Russwin 606K76, and do the alternatives come in the same?
The 606K76 27B2 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, which is a different appearance. For a Corbin Russwin mortise cylinder where the plug face is visible and needs to match surrounding trim, pick between the Satin Brass and Satin Chrome options.
15) What do I use for an Emtek handleset instead of the Corbin Russwin 606K76?
The 606K76 27B2 plug is a commercial mortise cylinder part and is not intended for Emtek trim. For Emtek, the Emtek CY4 cylinder is sold each as a parts item, the Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock as well as Emtek handleset and deadbolt outside cylinder positions.
