Corbin Russwin 293K02 59A1 626 – Frequently Asked Questions

1) Will the 293K02 plug work in my 1-1/8 inch mortise cylinder?
No. The 293K02 plug is machined for 2-3/4 inch mortise cylinder applications. A 1-1/8 inch cylinder is a different length and takes a different plug, so this part won't drop in. If you're working on a 1-1/8 inch commercial mortise cylinder, the Detex MC65 is a complete 1-1/8 inch 6-pin mortise cylinder, though it comes in a Schlage C keyway rather than a Corbin Russwin keyway.
2) What does the 59A1 keyway mean for keying this into my existing Corbin Russwin system?
59A1 is a Corbin Russwin keyway profile, so the plug will accept keys cut on 59A1 blanks and can be pinned into an existing 59A1 masterkey system. If the rest of your building runs a different Corbin Russwin keyway, the key won't enter this plug, so match the keyway stamped on the cylinders you already have before ordering.
3) Does a 7-pin plug matter if my existing Corbin Russwin cylinders are 6-pin?
Yes, it changes the key. A 7-pin plug is cut for 7-pin keys, so a 6-pin key from your existing cylinders will not operate it and it cannot be pinned into a 6-pin system. The 293K02's 7-pin tumbler arrangement is used where tighter key control and more masterkeying levels are wanted. Standardize on one pin count across an opening group or you'll end up carrying two keys.
4) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 293K02?
The 293K02 is a 7-pin plug, a replacement component for 2-3/4 inch mortise cylinders, not a finished cylinder assembly. If the opening needs a whole mortise cylinder, the Detex MC65 is a complete 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 mortise cylinder with five-pin security that works on doors from 1/2 inch thickness up. Choose the complete cylinder when you are not rebuilding an existing Corbin Russwin cylinder shell.
5) Is a rim cylinder like the Schlage 20-021 a substitute for the Corbin Russwin 293K02?
No. The 293K02 is a mortise cylinder plug built for 2-3/4 inch Corbin Russwin mortise cylinders. The Schlage 20-021 and 20-022 are rim cylinders, 6-pin, differing from each other in tailpiece cam orientation - vertical on the 20-021 and horizontal on the 20-022. Rim cylinders mount behind a rim exit device or rim deadlock and are not interchangeable with a mortise cylinder body.
6) The 293K02 is a Corbin Russwin 59A1 keyway. What is comparable if our system is keyed to another manufacturer?
The 293K02 carries the 59A1 keyway for use inside the Corbin Russwin keying system. For other master key systems, the Detex MC65 mortise cylinder is supplied in the Schlage C keyway, the Schlage 20-057-C full size interchangeable core is also C keyway, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series 6-pin G keyway, keyed different with two cut keys. Match the keyway to the existing system before ordering.
7) Will the 293K02 work in an aluminum storefront narrow stile door?
The 293K02 is a plug component for 2-3/4 inch Corbin Russwin mortise cylinders, which is a length used in swinging commercial door mortise locks rather than narrow stile hardware. For Adams Rite storefront deadlocks, the 4024 cylinder pull mounts with a trim plate and the 4025 five pin tumbler cylinder pull uses through-screws, both for the MS1847 deadlock/deadlatch; the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch. The Adams Rite 4036 is a Grade 1 mortise cylinder suited to doors from 1/2 inch thick.
8) What finishes does the 293K02 plug come in, and will it match my trim?
Two finishes: 606 Satin Brass and 626 Satin Chrome. 626 Satin Chrome is the usual match for brushed nickel and satin chrome lock trim, 606 Satin Brass for brass hardware. Since only the plug face shows at the keyway, pick the finish that matches the surrounding cylinder ring and lever trim.
9) I need to re-key a whole building of mortise locks. Is a plug like this the right approach, or should I use interchangeable cores?
Replacing plugs means pulling and disassembling each cylinder, which is fine for one-off repairs and for keeping an existing 59A1 Corbin Russwin system intact. If you want to re-key openings in seconds without taking hardware apart, move to a full-size interchangeable core platform instead: the BEST 1C 5-pin core or the BEST 1CDF drill-resistant 7-pin patented core, or on the Schlage side the 20-057 FSIC rim cylinder. Those require housings prepped for interchangeable cores, so it's a system decision, not a part swap.
10) Are keys included with the 293K02 plug?
The 293K02 is the plug as a bare component, so plan on having 59A1 blanks and pins on hand. That's different from a complete cylinder purchase such as the Schlage 20-021 rim cylinder, which is supplied with 2 keys. Locksmiths ordering this part are normally pinning it to an existing key bitting anyway.
11) Can I use this plug in a rim cylinder or a key-in-lever cylinder?
No. It's cut for mortise cylinder bodies, not rim or key-in-lever housings. For a rim application look at a rim cylinder such as the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam); for key-in-knob or lever replacement, the Kaba Ilco 1539 universal key-in-knob/lever cylinder covers that side.
12) We want to standardize on interchangeable cores instead of rekeying plugs. What are the options?
The 293K02 plug is pinned and serviced inside the cylinder, which means a locksmith pulls the cylinder to rekey. If the goal is core swaps at the door, BEST interchangeable core products cover that approach: the 1C series standard 5-pin core, the 1CB 150 series interchangeable core, and the 1CDF drill-resistant patented interchangeable core in 7-pin brass. Schlage's equivalent is the 20-057 full size interchangeable core rim cylinder with convertible tailpiece cam, also offered as the 20-057-C in C keyway, 643E Aged Bronze.
13) Our doors are key-in-knob or key-in-lever, not mortise. What replaces the cylinder there?
The 293K02 plug only serves 2-3/4 inch mortise cylinders. For knob and lever bodies, Kaba Ilco offers the 1539 series key-in-knob/lever universal cylinder and the 1599 key-in-knob replacement cylinder, plus the 1579 knob and lever cylinder built for Sargent locks. For a keyed deadbolt, the Ilco 1549 key-in-deadbolt cylinder covers that function. Falcon's A23161-05 G is a key-in-lever cylinder in the RU/T series.
14) We need a cylinder that looks keyed but does not operate. Is the 293K02 available that way?
The 293K02 is a functioning 7-pin plug intended to restore an operating 2-3/4 inch mortise cylinder. If the opening needs the appearance of a keyed cylinder with no operation - an inactive leaf or a trim filler - the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose.
15) We need higher pin count for key control. How does the 293K02 compare to other high-security cylinder options?
The 293K02 uses a 7-pin tumbler plug with the 59A1 keyway for controlled key duplication. On the interchangeable core side, the BEST 1CDF is a drill-resistant patented core also in 7-pin brass, versus the BEST 1C standard 5-pin core. Medeco offers 6-pin and 5-pin retrofit cylinders such as the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1065140 5-pin retrofit for Arrow JL interconnected locks and Emtek handlesets.
16) Can I use the 293K02 on an Emtek handleset or deadbolt?
No. The 293K02 is a Corbin Russwin mortise cylinder plug for 2-3/4 inch cylinders and does not fit Emtek trim. For Emtek, the Emtek CY4 cylinder is the direct part, and Medeco offers retrofits: the 1065244 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, the 1065140 5-pin retrofit for Emtek handleset and deadbolt outside cylinder applications, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
17) Is the 293K02 suitable for high-traffic commercial doors like schools and hospitals?
It's a commercial-grade component, made to Corbin Russwin's own cylinder tolerances, and it's used in office buildings, schools, healthcare facilities, government buildings, multi-tenant residential and retail. For a residential handleset or deadbolt, a plug like this is the wrong part.
18) Does the finish on the 293K02 limit which comparable cylinders will match our hardware?
The 293K02 plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to either a brass-tone or chrome-tone trim set. Among the comparable cylinders, the Schlage 20-057-C is specified in 643E Aged Bronze, a darker tone that will read differently alongside satin brass or satin chrome trim. Confirm the finish code on the surrounding hardware before mixing.
