Corbin Russwin 334K01 57C1 626 – Frequently Asked Questions

1) Is the Corbin Russwin 334K01 a complete interchangeable core or just the plug?
It is the plug only, not a finished core. The 334K01 57C1 is an individual X Class plug for the Corbin Russwin 8000-6 Interchangeable Core system, sold as a replacement component. A locksmith pins and assembles it into the core housing; if you need a drop-in assembled core instead, you want a complete IC core rather than this part.
2) Will the 334K01 plug work in my Corbin Russwin 8000-6 keying system?
Yes, that is exactly what it is built for. The 334K01 X Class plug is engineered for the Corbin Russwin 8000-6 Interchangeable Core platform, which allows tool-free core removal for key control. It will not fit other manufacturers' interchangeable core formats such as BEST-style 1C/1CB cores or Schlage full size IC.
3) Does the 334K01 take 5-pin or 6-pin keying?
Both. The plug accommodates 5-pin and 6-pin configurations, so it can be pinned into an existing 5-pin program or a 6-pin master key system without changing plugs. That flexibility matters when a facility is migrating masterkeying levels across a building.
4) What keyway options come on the Corbin Russwin 334K01 57C1 plug?
Two keyway choices are offered: C1 and C2, within the 57C keyway designation. Order the one that matches the keyway already cut into your existing Corbin Russwin system, otherwise your building keys will not enter the plug.
5) I need a full size interchangeable core on a Schlage C keyway, not a Corbin Russwin plug - what should I order?
The Corbin Russwin 334K01 57C1 is a plug for the Corbin Russwin 8000-6 Interchangeable Core system and is cut to the 57C keyway, so it will not serve a Schlage C keyed facility. For a full size interchangeable core on the C keyway, the Schlage Commercial 20-057-C is an FSIC core in C keyway, supplied in 643E Aged Bronze. If the housing is a rim application and you want to key the core yourself, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys.
6) What is the interchangeable core equivalent to the Corbin Russwin 334K01 57C1 plug if the building is keyed to a BEST small format system?
The Corbin Russwin 334K01 57C1 is an individual X Class plug for the Corbin Russwin 8000-6 Interchangeable Core system with the 57C keyway, so it only works inside a Corbin Russwin 8000-6 keying program. A building keyed to a BEST small format system takes a BEST core instead: the BEST 1C Series standard 5-pin cylinder core, or the BEST Peaks 1CB 150 Series interchangeable core cylinder. Those are complete cores rather than a bare plug, so they drop straight into a BEST-prepped housing.
7) Is a rim cylinder a substitute for the Corbin Russwin 334K01 plug on an exit device?
No. The 334K01 57C1 is a bare X Class plug that goes inside a Corbin Russwin 8000-6 interchangeable core - it is a component, not a complete cylinder, and it has no cam or tailpiece of its own. An exit device that needs a conventional rim cylinder takes something like the Schlage Commercial 20-021, a 6-pin rim cylinder with a vertical tailpiece cam and two keys, or the 20-022, the same rim cylinder with a horizontal tailpiece cam. Confirm which cam orientation the exit device calls for before ordering.
8) Will the Corbin Russwin 334K01 57C1 work in an Adams Rite storefront deadlock?
No. The 334K01 57C1 is a plug for the Corbin Russwin 8000-6 interchangeable core system and has no cylinder body or mounting of its own. Adams Rite MS1847 deadlock and deadlatch openings take a cylinder pull such as the Adams Rite 4024, which mounts with a trim plate, or the 4025, a five pin tumbler cylinder pull with through-screws. On a wood door with the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part.
9) Is this a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. It is an authentic Corbin Russwin cylinder component, which is what keeps it inside the factory keying program and tolerances for the 8000-6 IC system. That matters for institutional key control, where a non-factory plug can break restricted key records.
10) Is the 334K01 plug suitable for a school or hospital, or is it residential grade?
Commercial. The 334K01 57C1 is a commercial-grade cylinder part intended for institutional and commercial access control, including office buildings, schools, healthcare facilities, government buildings and multi-tenant properties. It is also used on retrofit work inside existing Corbin Russwin 8000-6 IC keying programs.
11) Is there a mortise cylinder alternative if my door does not use an interchangeable core?
Yes. Where the lock is prepped for a conventional mortise cylinder rather than an IC core, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated for doors 1/2 inch and up. Neither is keyed into a Corbin Russwin 57C program, so they suit a standalone opening rather than an existing Corbin master key system.
12) Can I use a key-in-knob replacement cylinder in place of the Corbin Russwin 334K01 57C1?
They are not interchangeable. The 334K01 57C1 is an X Class interchangeable core plug built for the Corbin Russwin 8000-6 system, where the whole core pulls with a control key. A key-in-knob replacement cylinder such as the Kaba Ilco 1599 or the 1539 Series key-in-knob and lever universal cylinder is a conventional cylinder that installs into the knob or lever itself, with no core removal feature. For a Sargent knob or lever, the Kaba Ilco 1579 is the corresponding cylinder.
13) The Corbin Russwin 334K01 is a Corbin keyway - what is the equivalent key-in-lever cylinder for a Falcon lockset?
The 334K01 57C1 plug is cut to the Corbin Russwin 57C keyway and belongs to the Corbin Russwin 8000-6 interchangeable core program, so it only keys into Corbin Russwin hardware. For a Falcon lever, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, supplied keyed different with two cut keys.
14) What finishes is the Corbin Russwin 334K01 plug available in?
Satin brass (606) and satin chrome (626). Pick the one that matches the other cylinders on the opening; on a facility standardized to 626 satin chrome trim, a 606 plug face will read as a mismatch even though it functions identically. Both finishes are offered in the C1 and C2 keyways.
15) What finishes does the Corbin Russwin 334K01 plug come in and how does that compare to other interchangeable core options?
The Corbin Russwin 334K01 57C1 plug is offered in 606 Satin Brass and 626 Satin Chrome, each available with a C1 or C2 keyway. Among comparable interchangeable core products, the Schlage 20-057-C full size interchangeable core is supplied in 643E Aged Bronze, so if the other cylinders on the opening are a darker bronze that is a different look entirely.
