Corbin Russwin 334K01 27A1 626 – Frequently Asked Questions

1) Which keyway do I have to specify when ordering the 334K01 plug?
Two keyway choices are offered, A1 and A2, both within the Corbin Russwin A keyway family. Pick the one that matches the existing keys on the building, since a plug in the wrong keyway section will not accept your key even though the core body is the same.
2) Can I use this plug in a Best or Schlage interchangeable core?
No. The 334K01 is made for the Corbin Russwin 8000-6 interchangeable core and the Corbin Russwin A keyway, and it does not interchange with other manufacturers' core platforms. For a Best small format core, the BEST 1C Series standard 5-pin core or the 1CB 150 Series interchangeable core are the parts to look at; for Schlage full size interchangeable core, the Schlage 20-057 FSIC cylinder.
3) Is the Corbin Russwin 334K01 27A1 plug the same thing as a complete interchangeable core?
No. The 334K01 27A1 is an individual X Class cylinder plug for the Corbin Russwin 8000-6 interchangeable core in the A keyway, sold as a replacement part for rekeying or core servicing rather than as a finished core. If you need a complete, ready to install interchangeable core instead of a plug, the BEST 1CB Peaks 150 Series interchangeable core cylinder or the BEST 1C Series standard 5-pin cylinder core are supplied as cores. Those are BEST figure-eight cores and key into BEST keyways, so they replace a core in BEST-prepped hardware, not in Corbin Russwin 8000-6 housings.
4) We need a full size interchangeable core rim cylinder, not a loose plug. What should I look at?
The 334K01 27A1 is a bare X Class plug for Corbin Russwin 8000-6 interchangeable cores and has no housing, cam or tailpiece of its own. For an FSIC rim application, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E aged bronze finish. Both are Schlage keyway products, so they stand outside a Corbin Russwin A keyway master key system.
5) What do I use for a narrow stile aluminum storefront instead of the Corbin Russwin 334K01 plug?
A storefront deadlock takes a mortise cylinder or a cylinder pull, not an interchangeable core plug. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated for doors 1/2 inch minimum thickness. For a pull-and-cylinder combination on an MS1847 deadlock, the Adams Rite 4024 mounts with a trim plate and the 4025 is a five-pin tumbler cylinder pull with through-screws; the Adams Rite 4026 is the five-pin cylinder pull for wood door applications with the 5017 deadlock.
6) What are the 27, 57, 67 and 77 options on this Corbin Russwin plug?
Those are design designations offered alongside the finish and keyway selections, and all four are available. If you are matching existing Corbin Russwin cylinder parts already in service, specify the same designation as the parts you are rebuilding so the keying and part call-out stay consistent across the site.
7) I manage an office building and just need the lock rekeyed. Is a plug the right thing to buy?
Only if you or your locksmith are servicing the interchangeable cores themselves. The plug is the pinned part inside the core and requires pinning kit work and a key machine. Most property managers are better served ordering complete interchangeable cores keyed to their system; buy the plug when a locksmith is rebuilding cores in house for a Corbin Russwin 8000-6 system.
8) What is an alternative if I need a keyed mortise or rim cylinder rather than a core plug?
A plug will not serve there. For a mortise application, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin option, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway. For rim devices, the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) are 6-pin rim cylinders.
9) If the opening takes a standard rim cylinder instead of an interchangeable core, what替 do I order?
Order a conventional rim cylinder rather than the 334K01 27A1 plug. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Pick the cam orientation that matches the exit device or auxiliary lock the cylinder drives.
10) The lock I am servicing is a key-in-lever, not an interchangeable core. Is the 334K01 plug still the right part?
No. The 334K01 27A1 plug fits the Corbin Russwin 8000-6 interchangeable core. For key-in-knob and key-in-lever housings, the Kaba Ilco 1539 Series 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 6-pin key-in-lever cylinder in the G keyway, keyed different with two cut keys. Match the replacement to the lock brand and keyway already in service.
11) We want higher key control than a standard A keyway plug. What are the options?
The 334K01 27A1 is supplied in the standard Corbin Russwin A keyway, in A1 and A2 variations. If the facility wants patented or drill resistant key control instead, the BEST 1CDF is a drill resistant patented interchangeable core with 7 pins in brass, 150 Series. Medeco cylinders such as the 1012040 6-pin lazy motion rim cylinder are another restricted-key route for retrofit work. Both move the opening into a different keyway family, so a whole-system changeover is the practical way to adopt them.
12) Our exit devices are Schlage C keyway. Can we use the Corbin Russwin 334K01 27A1 plug to match them?
No. The 334K01 27A1 is cut for the Corbin Russwin A keyway in A1 and A2, so it will not accept a Schlage C key. For C keyway work, the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, and the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in the Schlage C keyway. Keep one keyway family across the building so the master key hierarchy stays intact.
13) What finishes does the Corbin Russwin 334K01 X Class plug come in?
Two: 606 satin brass and 626 satin chrome. On an interchangeable core, only the plug face shows, so choose the one that matches the surrounding trim (626 is the usual pick alongside satin chrome and brushed stainless lever hardware).
14) Is the Corbin Russwin 334K01 plug rated for commercial use?
Yes, it is a commercial-grade Corbin Russwin cylinder part, used in offices, schools, healthcare, government buildings, multi-tenant residential, industrial and retail sites where cores are rekeyed in service.
15) I need a non-keyed filler where the cylinder used to be. Is a plug the right part?
No. The 334K01 27A1 is a functional keyed plug for the 8000-6 interchangeable core and is meant for rekeying or core servicing. For a non-functional opening, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the prep without operating hardware.
16) What retrofit cylinders exist for residential style handlesets and deadbolts if the 334K01 plug does not apply?
The 334K01 27A1 is a commercial X Class plug for Corbin Russwin 8000-6 cores. For handleset and deadbolt retrofits, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied 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. Emtek's own CY4 cylinder is sold each as a parts item.
