Corbin Russwin 564K59 27B1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 564K59 27B1 - a complete cylinder or just the plug?
It is the cylinder plug only, not a complete cylinder. The 564K59 27B1 is an Individual X Class plug made for the Corbin Russwin CK4429 lock cylinder, supplied with a new tailpiece so no extra parts are needed to finish the swap. If you need a whole cylinder rather than a plug, this is the wrong part.
2) Will this plug work in a 6-pin Corbin Russwin cylinder, or only 5-pin?
Both. The plug accepts 5-pin and 6-pin configurations, so a locksmith can use the same part whether the building is keyed to a 5-pin or 6-pin system on the B keyway.
3) What do the 27, 57, 67 and 77 pin depth choices mean when ordering this plug?
Pin depth designates the chamber depth system the plug is cut for, and the 564K59 is offered in 27, 57, 67 and 77. It has to match the depth system your Corbin Russwin masterkey system was built around, otherwise the plug cannot be pinned to your existing keys. Get that number from your key records or the system bitting list before you order.
4) Is the Corbin Russwin 564K59 27B1 a complete cylinder, or do I need a full cylinder like the Schlage 20-021?
The 564K59 27B1 is a plug only - the keyed plug assembly for a Corbin Russwin CK4429 cylinder, supplied with a new tailpiece and cut to the B keyway in 5-pin and 6-pin configurations. If the housing itself is damaged or you are building a new opening, you need a complete cylinder instead: the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same rim cylinder with a horizontal tailpiece cam.
5) We want to be able to swap keying without pinning plugs - what should we use instead of the Corbin Russwin 564K59 27B1?
The 564K59 27B1 is a keyed plug that is pinned to a B keyway and installed into a CK4429 cylinder, so rekeying means working the plug. If you want field-swappable keying, look at an interchangeable core platform instead: the BEST 1CB is a Peaks 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core 7-pin brass 150 Series core, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
6) My lock is a key-in-lever, not a Corbin Russwin CK4429 - is the 564K59 27B1 plug the right part?
No. The 564K59 27B1 is engineered specifically for the Corbin Russwin CK4429 cylinder. For key-in-knob and key-in-lever replacements, the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with two cut keys.
7) I need a mortise cylinder with a Grade 1 rating for a storefront - is the Corbin Russwin 564K59 27B1 what I want?
No. The 564K59 27B1 is a replacement plug for a CK4429 cylinder in the Corbin Russwin X Class key system. For a mortise cylinder on a storefront, the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1 with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch 6-pin commercial-grade mortise cylinder in the Schlage C keyway.
8) I manage a building with Corbin Russwin X Class keys. Does replacing a plug break the key system?
No, provided you order the matching keyway section and pin depth. The X Class designation is a controlled key section, and using the genuine 564K59 plug keeps that key control intact rather than opening the cylinder up to an uncontrolled blank. It gets pinned to your existing system, so the same keys keep working across the other doors.
9) I need a complete replacement cylinder, not a plug. What else does ZenSupply carry?
Depends on the cylinder type in the door. For a rim device, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same in horizontal cam. For an interchangeable core system, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and BEST offers the 1C5 standard 5-pin core and the 1CB Peaks 150 Series core. For a mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin in Schlage C keyway. None of these are on a Corbin Russwin B keyway, so keys would not interchange with your existing system.
10) Do I have to buy a tailpiece separately with the 564K59 plug?
No. A new tailpiece ships with the plug, so it goes in as a complete ready-to-install replacement for the CK4429 cylinder without sourcing hardware separately. Keep the old tailpiece as a spare if the cam orientation on your cylinder is anything unusual.
11) Will this plug fit a Corbin Russwin cylinder other than the CK4429?
It is engineered specifically for the CK4429 lock cylinder, and that is the fitment we can confirm. If the cylinder in your door carries a different Corbin Russwin designation, verify the housing before ordering rather than assuming the plug drops in.
12) What is the difference between the Corbin Russwin 564K59 27B1 plug and a BEST 1C5 core?
Both are the keyed working element rather than a complete lock, but they belong to different systems. The 564K59 27B1 is a Corbin Russwin X Class individual plug for the CK4429 cylinder, offered in 606 satin brass and 626 satin chrome with B1 and B2 keyways and pin depths of 27, 57, 67 and 77. The BEST 1C5 is a standard 5-pin cylinder core from the BEST Standard and Premium Cores range and drops into BEST interchangeable core housings.
13) Will the Corbin Russwin 564K59 27B1 work in a deadbolt?
The 564K59 27B1 is a plug for the Corbin Russwin CK4429 cylinder, not a deadbolt cylinder. For deadbolt applications the Kaba Ilco 1549 is a key-in-deadbolt cylinder listed with a deadbolt function, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
14) The tailpiece on my cylinder is for an Emtek or Arrow lock - can I use the Corbin Russwin 564K59 27B1 tailpiece?
The new tailpiece supplied with the 564K59 27B1 is matched to the Corbin Russwin CK4429 cylinder, not to other manufacturers' trim. Where an Emtek or Arrow tailpiece is required, 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 and Emtek handleset and deadbolt outside cylinder. The Emtek CY4 is also carried as an Emtek cylinder part.
15) I need a non-functioning cylinder just to fill a hole - is a plug like the 564K59 27B1 the cheap way to do it?
The 564K59 27B1 is a functioning keyed plug for the CK4429 cylinder and is meant for real key operation in the X Class system. When you only need to fill and dress a rim cylinder prep, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose.
16) Can the Corbin Russwin 564K59 27B1 be used on an Adams Rite MS1847 deadlock?
No - it is built for the Corbin Russwin CK4429 cylinder. Adams Rite deadlocks take their own cylinder pulls: the 4024 cylinder pull mounts with a trim plate 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.
17) Our facility standardizes on a restricted keyway - how does the Corbin Russwin 564K59 27B1 compare to the Schlage 20-057-C on key control?
The 564K59 27B1 keeps you inside the Corbin Russwin X Class key control program, with B keyway plugs offered in B1 and B2 and pin depths 27, 57, 67 and 77 for CK4429 cylinders. The Schlage 20-057-C is a full size interchangeable core cylinder in the Schlage C keyway with a 643E aged bronze finish, and the BEST 1CDF is a drill-resistant preferred patented interchangeable core in 7-pin brass. Choose by which key system your facility already holds.
18) Which finishes does the Corbin Russwin 564K59 cylinder plug come in?
Two: 606 satin brass and 626 satin chrome. Since the plug face is the visible part of the cylinder, match it to the trim on the door, 626 with satin chrome or brushed nickel hardware, 606 with brass.
19) Is this Corbin Russwin plug suitable for high-traffic commercial doors or is it a residential part?
Commercial. It is built for institutional and commercial use, the kind of service you see in offices, schools, hospitals, government buildings, retail and multi-tenant residential, and is not a light-duty residential component.
