Corbin Russwin 416K08 57C1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 416K08 plug, and is it a complete cylinder?
It's a cylinder plug, not a finished cylinder or a complete core. The 416K08 57C1 is the 7-pin X Class plug that goes into a Corbin Russwin 8000-7 core with the 57C keyway. If you need a ready-to-install interchangeable core or a mortise cylinder instead, order that assembly, not this plug. Locksmiths buy this one to rebuild or rekey an existing Corbin Russwin core.
2) What keyway and finish choices do I have to specify when ordering the 416K08?
Two things get picked on the order: keyway, C1 or C2, and finish, either 606 satin brass or 626 satin chrome. All four combinations are offered. The keyway has to match the key system already in the building, otherwise your existing keys won't enter the plug.
3) Can I use this Corbin Russwin plug in a Schlage or BEST cylinder?
No. The 416K08 is keyed and machined to the Corbin Russwin 57C keyway and the 8000-7 core, so it is brand-specific. For a Schlage system, a full size interchangeable core such as the Schlage 20-057 FSIC cylinder is the right family. For BEST small format IC, look at the BEST 1CDF 7-pin interchangeable core.
4) Will a Schlage FSIC core work in place of this Corbin Russwin plug?
No. The Corbin Russwin 416K08 57C1 is keyed to the 57C keyway and built for the Corbin Russwin 8000-7 core, so it is not cross-compatible with Schlage core platforms. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the Schlage C keyway - those belong in Schlage FSIC housings. Treat them as separate key systems rather than substitutes for one another.
5) I need a mortise cylinder for a storefront lock, not a plug. What should I order?
The Corbin Russwin 416K08 57C1 is a plug that seats in an 8000-7 core and will not thread into a mortise lock body on its own. For a mortise application, 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 a 1/2 inch minimum door thickness. Pick by the keyway the site is standardized on.
6) If I need a complete interchangeable core rather than just the plug, what 7-pin option is there?
The Corbin Russwin 416K08 57C1 is a cylinder plug - a replacement part that goes into an 8000-7 core, not a finished core you can drop into a housing. If you need a complete 7-pin interchangeable core instead, the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass, 150 Series. The tradeoff is keying system: the 416K08 stays inside Corbin Russwin 57C keying, while the 1CDF puts the opening on the BEST patented platform, so choose based on which key system the facility already runs.
7) Why choose a 7-pin plug over a 5-pin for a facility key system?
More pin chambers give you more room in the masterkeying matrix and tighter key control, which is why institutional systems run 7-pin. The 416K08 is 7-pin on the 57C keyway. A 5-pin cylinder core, like the BEST 1C 5-pin core, is the simpler option where there is no deep master key hierarchy to support.
8) What is a simpler 5-pin core option if 7-pin key control is more than the building needs?
The Corbin Russwin 416K08 57C1 plug is built around a 7-pin tumbler arrangement for tighter key control. Where a building does not need that depth of keying, the BEST 1C5 is a standard 5-pin cylinder core, and the BEST 1CB is a Peaks 150 Series interchangeable core. Both are complete cores rather than plugs, so they are a swap at the core level instead of a bench rebuild of an existing Corbin Russwin cylinder.
9) What do I order if the opening needs a rim cylinder for an exit device instead?
The Corbin Russwin 416K08 57C1 plug is a component of an 8000-7 core and has no tailpiece or cam of its own. For an exit device you want a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, each supplied with two keys. Match the cam orientation to what the device requires.
10) Is there a replacement cylinder that fits a key-in-knob or key-in-deadbolt lock instead of a core?
The Corbin Russwin 416K08 57C1 is a plug for a Corbin Russwin 8000-7 core, so it does not address a knob or deadbolt cylinder directly. For those, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1549 is a key-in-deadbolt cylinder, and the 1599 is a key-in-knob replacement cylinder. If the lock body is Sargent, the Kaba Ilco 1579 is the knob and lever cylinder made for Sargent.
11) For an aluminum storefront with an Adams Rite deadlock, does a Corbin Russwin plug apply?
No. The Corbin Russwin 416K08 57C1 is a 7-pin X Class plug for the 8000-7 core and is not a storefront trim part. For an Adams Rite MS1847 deadlock or deadlatch, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws. On a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part.
12) We use a Falcon key-in-lever cylinder elsewhere. Is that the same kind of part as the 416K08?
They are different pieces. The Corbin Russwin 416K08 57C1 is a bare 7-pin plug carrying the 57C keyway, intended to go inside an 8000-7 core. The Falcon A23161-05 G is a complete key-in-lever cylinder from the RU/T series with a 6-pin G keyway, keyed different and supplied with two cut keys. The Falcon part is ready to install in a lever lock; the Corbin Russwin plug is a bench-level rebuild component within the Corbin Russwin key system.
13) What high-security cylinder options exist if this Corbin Russwin plug is for a residential-style handleset or deadbolt?
The Corbin Russwin 416K08 57C1 is specified for commercial use as a replacement cylinder part, and it is a plug for the 8000-7 core rather than a deadbolt cylinder. For handlesets and deadbolts, Medeco offers the 1075127 5-pin rim type lazy motion single cylinder, the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065244 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
14) Is the 416K08 plug suitable for commercial buildings, or is it a residential part?
It's a commercial part. Corbin Russwin cylinder components like this one are used in offices, schools, hospitals, government buildings, warehouses, retail, and multi-tenant residential where a master keyed Corbin Russwin system is already in place.
15) Does the finish on a cylinder plug matter if it's inside the lock?
Only where the plug face shows through the trim. Pick 626 satin chrome to match satin chrome or brushed nickel hardware, and 606 satin brass to match brass trim. Function is identical between the two.
16) Is there a non-keyed cylinder option for a door that only needs the look of a lock?
The Corbin Russwin 416K08 57C1 is a working 7-pin plug and always carries a keyway - the 57C series, with C1 and C2 keyway choices offered in 606 satin brass and 626 satin chrome. If the opening needs the appearance of a cylinder without keyed operation, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the part designed for that purpose.
