Corbin Russwin 293K03 59B1 626 – Frequently Asked Questions

1) Is the Corbin Russwin 293K03 a complete mortise cylinder or just the plug?
It's the plug only. The 293K03 is a 7-pin plug component built for 3 inch mortise cylinder applications, sold as a genuine Corbin Russwin replacement part rather than a full cylinder housing with cam and rings. If you need a complete keyed mortise cylinder to drop into a lock body, this is not it. You'd be buying this to rebuild or re-key an existing Corbin Russwin cylinder assembly and keep the plug matched to the housing.
2) Will the 293K03 plug work in my existing Corbin Russwin keying system?
Only if your system runs the 59B1 keyway. The plug is cut to the Corbin Russwin 59B1 proprietary keyway, so it drops into an existing 59B1 masterkey system and keeps key continuity across the facility. A building keyed to any other Corbin Russwin section will not accept it, so pull a key and confirm the keyway stamp before ordering.
3) I need a mortise cylinder for an exit device but not in the Corbin Russwin 59B1 keyway. What else is there?
The 293K03 plug is locked to Corbin Russwin 59B1, so it is no help on another brand's keying. For a Schlage C keyway mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in Schlage C. If your opening is an aluminum storefront deadlock, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin unit with a 1/2 inch minimum door thickness. Neither will key into a 59B1 system.
4) Can I use the 293K03 in a rim cylinder or a key-in-lever lock?
No. It's dimensioned for 3 inch mortise cylinder applications, which is a different body than a rim cylinder or a knob/lever cylinder. For rim applications use a rim cylinder such as the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam), both 6-pin with two keys. For key-in-knob or lever replacement, the Kaba Ilco 1599 key-in-knob cylinder or the Falcon A23161-05 G 6-pin key-in-lever cylinder are the right family.
5) What finishes does the Corbin Russwin 293K03 7-pin plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Match it to the housing and the surrounding trim, since the plug face is what shows through the cylinder collar. 626 Satin Chrome is the usual choice on openings already running satin chrome or brushed stainless lever trim; 606 is for brass-finish suites.
6) Why choose a 7-pin plug over a 5 or 6-pin cylinder for a commercial building?
Pin count drives how deep a masterkey system can go. The 293K03's 7-pin tumbler arrangement yields more usable key-cut combinations than a standard 5 or 6-pin cylinder, which matters when you are running grand master, master, and sub-master levels across a large facility, and it adds resistance to unauthorized entry. For a single door with two keys, 6-pin is usually enough; for campus-wide or multi-tenant keying hierarchies, the extra chamber is what keeps the system expandable.
7) My facility wants interchangeable cores instead of fixed plugs. Is the 293K03 the right direction?
No. A 293K03 plug is a fixed-cylinder component, so re-keying means pulling the cylinder and repinning the plug. If the goal is core swaps at the door by maintenance staff, look at interchangeable core products instead: BEST 1CB 150 Series interchangeable core, the BEST 1CDF drill-resistant patented 7-pin brass core, or Schlage's 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Those let you rotate cores without disassembling the lock.
8) What is the exact part number I should quote for the 7-pin Corbin Russwin plug in 59B1?
Corbin Russwin model 293K03 59B1, then the finish code: 606 for Satin Brass or 626 for Satin Chrome. Quoting the keyway alongside the model matters, because 293K03 plugs exist in other Corbin Russwin keyway sections and the wrong section will not accept your keys.
9) Is a Schlage 20-021 rim cylinder a substitute for the Corbin Russwin 293K03?
No. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, which mounts through the door face for rim exit devices. The Corbin Russwin 293K03 is a 7-pin plug component for 3 inch mortise cylinder applications on the 59B1 keyway. The threaded mortise body and the rim housing are different mounting formats and do not interchange.
10) Is there a simpler 5-pin alternative to the 293K03 7-pin plug?
The Corbin Russwin 293K03 uses a 7-pin configuration for a greater number of key combinations than standard 5 or 6-pin cylinders. If fewer pins are acceptable, the BEST 1C series standard 5-pin cylinder core and the Adams Rite 4036 five-pin mortise cylinder are both 5-pin designs; note the 4036 is a complete mortise cylinder rather than a plug component.
11) Can I use the 293K03 on a residential handleset or Kwikset deadbolt?
The Corbin Russwin 293K03 is a commercial cylinder component for 3 inch mortise applications on the 59B1 keyway. For residential handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
12) Is this part suitable for high-traffic commercial doors, or is it residential grade?
Commercial. The 293K03 is classified as a commercial mechanical lock component and is used in office buildings, schools, healthcare facilities, government and municipal buildings, retail, industrial and warehouse space, and multi-tenant residential properties. It is a genuine Corbin Russwin part, so it holds fit and function inside the original cylinder assembly rather than approximating it.
13) Which finishes does the 293K03 come in, and how does that compare to the Schlage 20-057-C core?
The Corbin Russwin 293K03 7-pin mortise plug is offered in 606 Satin Brass and 626 Satin Chrome. The Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze with a C keyway, so it will not match a satin brass or satin chrome trim scheme.
14) Is a cylinder pull like the Adams Rite 4025 an alternative to the 293K03?
No. The Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws designed for use with the Adams Rite MS1847 deadlock/deadlatch, and the 4024 is the same pull with a trim plate mounting; the 4026 pull is for the Adams Rite 5017 wood door deadlock/deadlatch. Those are pull assemblies tied to specific Adams Rite deadlocks. The Corbin Russwin 293K03 is a 7-pin plug component on the 59B1 keyway for 3 inch mortise cylinder assemblies.
15) I need a cylinder that fills the hole but does not key - what is that instead of the 293K03?
The Corbin Russwin 293K03 is a working 7-pin plug pinned to the 59B1 keyway. When the opening needs a cylinder body with no keying function, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the blank-off option, though it is a rim format rather than a mortise plug.
