Corbin Russwin 334K00 59B1 626 – Frequently Asked Questions

1) What is the difference between the B1 and B2 keyway options on the Corbin Russwin 334K00?
Both are options on the same 334K00 standard plug, and they are two different keyway sections in the Corbin Russwin 59B family. The plug has to match the keyway already cut into your key system, so order the section your existing keys are made in. If your system was set up on 59B1, a B2 plug will not accept those keys.
2) Can I use this plug for both 5-pin and 6-pin Corbin Russwin master key systems?
Yes. The 334K00 standard plug supports both 5-pin and 6-pin configurations, so it can be pinned into a five-pin system or a six-pin one depending on how your master key schedule is built. That makes it usable across mixed installations where older five-pin openings and newer six-pin openings share the same key system.
3) What is the interchangeable core equivalent to the Corbin Russwin 334K00 if the building is keyed on a BEST system instead?
The Corbin Russwin 334K00 59B1 is a standard plug built for the Corbin Russwin 8000-6 interchangeable core platform in the 59B keyway, so it only works inside a Corbin Russwin IC system. A building keyed on BEST small format cores would instead use a BEST interchangeable core such as the BEST Peaks 1CB, a 1CB Series interchangeable core cylinder, or the BEST 1CDF drill resistant patented interchangeable core, a 7-pin brass 150 Series core. Those are complete cores, not individual plugs.
4) I need a whole core, not just a plug. What should I order?
The Corbin Russwin 334K00 59B1 is supplied as an individual standard plug for component-level replacement rather than a complete core assembly. If you want a ready-to-install core, the BEST 1C Series standard 5-pin cylinder core and the Schlage 20-057-C full size interchangeable core in the C keyway are both supplied as cores. Note that neither will key into a Corbin Russwin 59B system, so match the core to the key system already in the building.
5) For a mortise lock body rather than an IC housing, what cylinder should I use instead of the 334K00?
The Corbin Russwin 334K00 59B1 is an IC plug for the 8000-6 platform and is not a threaded mortise cylinder. For a mortise prep, the Adams Rite 4036 mortise cylinder is a five-pin Grade 1 cylinder in the 4036 Series with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway.
6) I manage a building with Corbin Russwin IC locks. Do I need a new core or just this plug?
If the core body and housing are sound and you only need to change the keying or replace a worn or damaged plug, the 334K00 handles it as a component-level replacement. It is catalogued as a replacement part for exactly that reason. If the core body itself is damaged, or you are moving to a different key system entirely, you need a complete interchangeable core instead of a plug.
7) Is this a residential deadbolt cylinder or a commercial part?
Commercial. The 334K00 is a cylinder component for Corbin Russwin's commercial mechanical lock line and the 8000-6 IC key control platform, the kind of system used in offices, schools, hospitals and multi-tenant buildings. For a residential deadbolt or key-in-knob replacement you want a different part altogether, such as a Kaba Ilco 1549 key-in-deadbolt cylinder or a 1599 key-in-knob replacement cylinder.
8) Is a standard plug the same thing as a rim or mortise cylinder?
No, and this is a common mix-up. The 334K00 is the plug that sits inside an interchangeable core, the part that carries the pins and the keyway. A rim or mortise cylinder is a complete housing that mounts in or on the door, like the Schlage 20-021 rim cylinder with a vertical tailpiece cam, the 20-022 with a horizontal cam, or the Detex MC65 1-1/8 inch 6-pin mortise cylinder. If you are replacing hardware in the door rather than rekeying a core, you want one of those, not a plug.
9) Does the Corbin Russwin 334K00 come keyed, or do I pin it myself?
It is supplied as an individual standard plug for the 8000-6 core, meaning it is the component a locksmith pins to your own 59B key schedule in either 5-pin or 6-pin. Plan on pinning kit, springs and key blanks on your side of the bench; the plug itself is the only thing in the order.
10) Will the Corbin Russwin 334K00 plug work in an exit device rim application?
The 334K00 59B1 is a plug for the Corbin Russwin 8000-6 interchangeable core, not a rim cylinder housing, so it does not mount to a rim exit device on its own. For rim applications the Schlage 20-021 rim cylinder uses a vertical tailpiece cam and the 20-022 uses a horizontal tailpiece cam, both 6-pin with two keys, while the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Choose the cam orientation the exit device requires.
11) What looks like a substitute for the Corbin Russwin 334K00 but is not?
Key-in-knob and deadbolt replacement cylinders are the common mix-up. The Kaba Ilco 1539 key-in-knob/lever universal cylinder, the 1549 key-in-deadbolt cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder are all complete cylinders for deadbolt and knob/lever applications, not plugs for a Corbin Russwin 8000-6 interchangeable core in the 59B keyway. Dropping one of those into an IC housing will not work.
12) Does the Corbin Russwin 334K00 fit an Adams Rite MS1847 deadlock?
No. The 334K00 59B1 is a standard plug for the Corbin Russwin 8000-6 interchangeable core in the 59B keyway. For Adams Rite MS1847 deadlock and deadlatch systems, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws; for a wood door, the 4026 five pin tumbler cylinder pull is made for the Adams Rite 5017 wood door deadlock/deadlatch.
13) Is there a 6-pin key-in-lever cylinder alternative if the doors are Falcon rather than Corbin Russwin?
The 334K00 59B1 plug supports 5-pin and 6-pin configurations but is keyed to the Corbin Russwin 59B keyway and belongs in an 8000-6 interchangeable core. On Falcon key-in-lever hardware, the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series with a 6-pin G keyway, keyed different and supplied with two cut keys.
14) What cylinder replaces the 334K00 for Emtek or Kwikset residential-style handlesets and deadbolts?
The Corbin Russwin 334K00 59B1 is a commercial IC plug for the 8000-6 platform and does not fit residential handleset hardware. Medeco covers those openings: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder, sold each.
15) What finishes does the Corbin Russwin 334K00 standard plug come in?
Two: 606 satin brass and 626 satin chrome. Both are offered in the B1 and B2 keyway sections, so you can match the plug face to the surrounding trim on the door. 626 satin chrome is the usual pick where the rest of the hardware is brushed chrome or satin stainless.
