Corbin Russwin 293K03 59B2 626 – Frequently Asked Questions

1) Will the 293K03 plug work in my existing Corbin Russwin keying system?
Only if your system runs the 59B2 keyway. The plug is cut for 59B2, so it keys into an existing Corbin Russwin 59B2 system and holds key control. A different Corbin keyway means a different plug part number, since the keyway is machined into the plug itself.
2) If I need a whole mortise cylinder instead of a rebuild part, what should I look at?
Go to a complete mortise cylinder rather than a plug. The Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Neither will key into a Corbin Russwin 59B2 system, so if key control matters you want a Corbin Russwin mortise cylinder in 59B2 instead.
3) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 293K03?
The Corbin Russwin 293K03 is a 7-pin plug, a replacement part that goes inside a 3 inch mortise cylinder shell during a rebuild, not a finished cylinder you can thread into a lock body. When the job calls for a whole mortise cylinder, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 series, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Both of those arrive as assembled cylinders; the 293K03 assumes you already have the shell and cam on the bench.
4) Can I use a BEST interchangeable core instead of rebuilding a Corbin Russwin cylinder with the 293K03 plug?
Only if you are changing the keying platform on that opening. The Corbin Russwin 293K03 is a 7-pin plug cut for the 59B2 keyway, so it keeps the door inside an existing Corbin Russwin key system. BEST interchangeable core products are a different architecture: the 1C5 is a standard 5-pin cylinder core, the 1CB is a Peaks 150 series interchangeable core cylinder, and the 1CDF is a drill resistant patented 7-pin brass interchangeable core in the 150 series. Those require the host hardware to accept a BEST-style figure-eight core, and they will not accept 59B2 keys.
5) What finishes does the Corbin Russwin 293K03 plug come in?
Two: 606 satin brass and 626 satin chrome. Match the plug to the cylinder collar and the rest of the trim on the opening, since the plug face is what shows at the keyhole.
6) Can I use a 7-pin plug in a cylinder that was originally 6-pin?
The 293K03 is built as a 7-pin plug sized for 3 inch Corbin Russwin mortise cylinders, so it belongs in a 7-pin 59B2 cylinder of that length. Pin count and keyway both have to match the housing and the keying system you're servicing; a 6-pin cylinder takes a 6-pin plug.
7) I manage a building with interchangeable-core locks. Is this the right part for me?
No. The 293K03 serves conventional 3 inch Corbin Russwin mortise cylinders that get taken apart and re-pinned. If your doors use full size or small format interchangeable cores, you swap the core instead, something like the BEST 1C 5-pin core or the Schlage 20-057 FSIC core, depending on brand.
8) What looks like a substitute for the 293K03 but will not work in a mortise lock?
Rim cylinders are the common mix-up. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same rim cylinder with a horizontal tailpiece cam; the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece. All of those mount to the face of the door and drive a tailpiece. The Corbin Russwin 293K03 is the 7-pin plug that goes inside a threaded 3 inch mortise cylinder shell driven by a cam, so none of the rim parts interchange with it.
9) The cylinder I am servicing is in a knob or lever, not a mortise lock. Is the 293K03 the right part?
No. The Corbin Russwin 293K03 plug is sized for 3 inch mortise cylinder applications. For key-in-knob and key-in-lever bodies, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder made for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, supplied keyed different with two cut keys. Those bodies use a different form factor than a mortise cylinder plug.
10) I am rebuilding a deadbolt, not a mortise lock. What takes the place of the 293K03 there?
The Corbin Russwin 293K03 is a mortise cylinder plug for commercial mortise assemblies. On deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder with a deadbolt function, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for Emtek handleset and deadbolt outside cylinders.
11) My opening is an aluminum storefront with an Adams Rite deadlock. Does the 293K03 apply?
Not directly. The Corbin Russwin 293K03 is a plug for 3 inch mortise cylinders used in commercial mortise lock assemblies. Adams Rite storefront hardware is served by its own parts: the 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch. For the cylinder itself in that family, the 4036 is a Grade 1 mortise cylinder rated for doors 1/2 inch minimum thickness.
12) Is this plug suitable for a house or only commercial locks?
It's a commercial component. The 293K03 is intended for commercial mortise lock servicing, the kind of work done in offices, schools, healthcare buildings and multi-tenant properties where cylinders are rebuilt rather than thrown away.
13) Are cut keys included with the 293K03 plug?
It ships as a bare plug, a rebuild component for a 59B2 cylinder. Cylinders sold as complete units often include keys, for example the Schlage 20-021 rim cylinder comes with two keys, but a plug is pinned and keyed by the locksmith to the existing system.
14) I need a filler where no key function is required. Is a 293K03 plug the cheapest way to fill the hole?
The Corbin Russwin 293K03 is a functioning 7-pin plug meant to restore keyed operation in a 3 inch mortise cylinder during a rebuild. If the opening needs a cylinder appearance with no keying at all, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose. Choose the 293K03 when the door has to key back into a 59B2 system.
15) How do I match the 293K03 finish to the rest of the cylinders on the building?
The Corbin Russwin 293K03 plug comes in 606 satin brass and 626 satin chrome, which covers the two most common commercial cylinder finishes. Among comparable cylinder parts, the Schlage 20-057-C full size interchangeable core is supplied in 643E aged bronze, a darker tone that will not blend with a run of 626 satin chrome trim.
