Corbin Russwin 334K01 27B1 626 – Frequently Asked Questions

1) Will a 334K01 plug work in my existing Corbin Russwin master key system?
It will if your system runs on the Corbin Russwin X Class B keyway family. The plug is cut for the B keyway and is made to fit inside the 8000-6 interchangeable core, so it keys into an existing X Class hierarchy without changing your key blanks. A system on a different Corbin Russwin keyway, or on another manufacturer's keyway, will not accept it.
2) What is the difference between the B1 and B2 keyway options on the 334K01?
B1 and B2 are two separate keyway cuts within the Corbin Russwin B family, and they are ordered as distinct plugs. Both are offered on the 334K01. You have to match whichever one your existing keys and cores are built on, because keys cut for one will not operate the other. Both B1 and B2 come in 606 satin brass and 626 satin chrome.
3) What do the 27, 57, 67 and 77 pin depth numbers mean when ordering this plug?
Those are the four pin depth designations available on the 334K01, and they determine how the plug is chambered for your keying system. Facilities standardized on one X Class depth system need the plug that matches it, or the pinning will not follow your existing key bitting. Every depth (27, 57, 67, 77) is offered in both B1 and B2 keyways and in both finishes.
4) Is the 334K01 plug the right part for a rim exit device or a mortise cylinder?
No. It is a plug for an 8000-6 interchangeable core and nothing else. For a rim device you want a rim cylinder such as the Schlage 20-021 with vertical tailpiece cam or the 20-022 with horizontal cam. For a mortise application, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder.
5) Is the Corbin Russwin 334K01 27B1 plug the same thing as a BEST 1CB interchangeable core?
No. The 334K01 27B1 is an individual X Class plug for the Corbin Russwin 8000-6 Interchangeable Core in a B keyway, so it is a component that goes into a Corbin Russwin core, not a finished core. The BEST Peaks 1CB is a complete 150 Series interchangeable core cylinder. If you need a ready-to-drop core rather than a plug for an existing Corbin Russwin 8000-6 housing, the 1CB is the core-level part.
6) Is there a drill resistant alternative if I am specifying for high security key control?
The Corbin Russwin 334K01 27B1 plug provides key control through the Corbin Russwin X Class system with a B keyway and 5 or 6-pin support. If the specification calls for a drill resistant patented core instead, the BEST 1CDF is a drill resistant preferred patented interchangeable core with 7 pins in brass, 150 Series. It is a BEST core and keys into a BEST system rather than a Corbin Russwin hierarchy.
7) Can I rekey 8000-6 cores without pulling the locks apart?
That is the point of the interchangeable core design. The 8000-6 core comes out of the housing with a control key and a replacement core or rebuilt plug drops in, so doors go back in service quickly without disassembling the lockset. It is why schools, hospitals and multi-tenant buildings standardize on IC systems for scheduled rekeying.
8) I need a full interchangeable core, not a Corbin Russwin plug. What else is available?
For a complete IC core rather than a plug, look at the BEST 1CB 150 Series interchangeable core, the BEST 1C Series standard 5-pin core, or the drill-resistant BEST 1CDF patented 7-pin core in the 150 Series. On the Schlage side, the 20-057 6-pin FSIC rim cylinder and the 20-057-C full size interchangeable core in C keyway are the full-size IC options. None of these will key into a Corbin Russwin X Class B system, so they suit a new or separate keying program rather than an add-on to your existing one.
9) I need a cylinder for a deadbolt, not an IC plug. What are my options?
The Corbin Russwin 334K01 27B1 is a plug for the 8000-6 Interchangeable Core and is used inside a master keyed X Class system. For deadbolt service, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the 1599 is a key-in-knob replacement cylinder, both catalogued for deadbolt function. Medeco offers the 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
10) Will a rim cylinder like the Schlage 20-021 or 20-022 work in place of the Corbin Russwin 334K01 plug?
No. The Corbin Russwin 334K01 27B1 is a replacement plug for the 8000-6 Interchangeable Core. The Schlage 20-021 and 20-022 are 6-pin rim cylinders supplied with two keys, differing from each other in tailpiece cam orientation - vertical on the 20-021 and horizontal on the 20-022. Rim cylinders mount through the door to drive a rim exit device and do not seat in an interchangeable core housing.
11) What is the equivalent part for a key-in-lever cylinder rather than an interchangeable core plug?
The Corbin Russwin 334K01 27B1 serves the 8000-6 Interchangeable Core system. For key-in-lever or key-in-knob cylinders, the Falcon A23161-05 G is a key in lever cylinder for the RU/T series with a 6-pin G keyway, keyed different with two cut keys, and the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder. The Kaba Ilco 1579 is a knob and lever cylinder made for Sargent locks.
12) What do I order if a door only needs a non-functioning cylinder for appearance?
The Corbin Russwin 334K01 27B1 is a keyed plug for the 8000-6 Interchangeable Core and is meant to operate within a master key system. For an opening that only needs the look of a cylinder, the BEST 12E Series dummy rim cylinder measures 1-5/32 inch in diameter and is a dummy rather than an operating cylinder.
13) Which cylinder should I use on an Emtek handleset or an Arrow JL interconnected lock?
Not the Corbin Russwin 334K01 27B1, which is a plug for the Corbin Russwin 8000-6 Interchangeable Core. For those openings, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the Emtek CY4 is sold as a single cylinder part.
14) What finishes does the Corbin Russwin 334K01 plug come in?
Two: 606 satin brass and 626 satin chrome. Most commercial openings on satin chrome lever trim take the 626 so the exposed plug face matches the rest of the hardware; 606 is the brass match. Finish here is cosmetic only, the keying is set by the keyway and pin depth you choose.
15) Is the 334K01 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin cylinder part, supplied as a factory replacement component for 8000-6 IC installations. That matters on restricted X Class systems, where key control depends on staying inside the manufacturer's own plug and keyway program.
16) What is the difference between the Adams Rite 4025 and 4026 cylinder pulls?
Both are five pin tumbler cylinder pulls, but they target different locks: the 4025 is designed for the Adams Rite MS1847 deadlock or deadlatch and mounts with through-screws, while the 4026 is designed for the Adams Rite 5017 wood door deadlock or deadlatch. Neither is interchangeable with the Corbin Russwin 334K01 27B1, which is a plug for the 8000-6 Interchangeable Core.
