Corbin Russwin 488K99 57C1 626 – Frequently Asked Questions

1) Which Corbin Russwin cylinders does the 488K99 plug fit?
The 488K99 X-Class plug is built for CK4200, UT5200 (.552 inch) and 2000-051 cylinder applications. If the cylinder on your door is one of those three platforms, the plug drops in as the OEM replacement part. Anything outside those platforms is a different plug.
2) Does the 488K99 plug work in both 5-pin and 6-pin cylinders?
It does. The plug accepts both 5-pin and 6-pin configurations, so the same part covers a 5-pin master keyed system and a 6-pin one. Your pinning kit and key bitting decide which you build it as.
3) Is this a complete cylinder or just the plug?
Just the plug. The 488K99 57C1 is the individual X-Class cylinder plug, a replacement component that goes into an existing CK4200, UT5200 or 2000-051 cylinder shell. You will still need pins, springs and keys to build it up. If you need a whole assembled cylinder, order a complete cylinder instead.
4) What should I use instead of the 488K99 plug if I want to rekey a door without pinning plugs by hand?
The 488K99 57C1 is a pinnable plug for Corbin Russwin CK4200, UT5200, and 2000-051 cylinders, so rekeying means working the plug. Where the goal is swapping a keyed element without pinning work, interchangeable core products cover that approach: the BEST 1CB 150 Series interchangeable core, the BEST 1C Series standard 5-pin core, or the Schlage 20-057-C full size interchangeable core in C keyway.
5) Is the Corbin Russwin 488K99 57C1 a complete cylinder, or do I still need a cylinder body?
The 488K99 57C1 is an individual X-Class cylinder plug - the keyed plug that drops into CK4200, UT5200 (.552 inch), or 2000-051 cylinder applications, not a finished cylinder assembly. If the job needs a complete keyed cylinder instead of a service part, a full mortise cylinder such as the Adams Rite 4036 Grade 1 mortise cylinder or a rim cylinder such as the Schlage 20-021 with vertical tailpiece cam is the item that installs on its own.
6) Will a Schlage C keyway cylinder work in place of the 488K99 57C1?
No. The 488K99 57C1 uses the Corbin Russwin 57C keyway and is offered in C1 and C2 keyway variants for that system. Schlage C keyway parts such as the Detex MC65 6-pin mortise cylinder or the Schlage 20-057-C core are cut for a different keyway family and will not key into a Corbin Russwin system built on 57C.
7) What finishes does the 488K99 cylinder plug come in?
Satin brass (606) and satin chrome (626). Both keyway options are offered in each, so you can match the plug face to the existing cylinder housing on the door.
8) Can I use this Corbin Russwin plug to rekey doors in an apartment or office building?
That is what it is for. Swapping plugs is the standard way to change key control on a Corbin Russwin opening without pulling the whole lock, and the part is a commercial-grade component intended for office, healthcare, education, hospitality and institutional servicing. Just confirm the existing cylinders are CK4200, UT5200 or 2000-051 before you buy a batch.
9) What should I use instead if I need a rim cylinder for an exit device rather than a Corbin Russwin plug?
The 488K99 is a plug only and will not serve as a rim cylinder. For exit device trim, a Schlage 20-021 rim cylinder uses a vertical tailpiece cam and the 20-022 uses a horizontal one, both 6-pin and supplied with two keys. Match the cam orientation to what your device requires.
10) What does the .552 inch reference on UT5200 compatibility mean for fitment?
That is the UT5200 plug diameter the part is cut to. If your UT5200 cylinder takes the .552 inch plug, this one seats correctly; a UT5200 housing built for a different diameter needs a different plug, so verify the bore before you order a quantity.
11) I need a keyed cylinder for a key-in-lever lock, not a plug. What covers that?
The 488K99 57C1 is a replacement plug for Corbin Russwin CK4200, UT5200, and 2000-051 cylinders. For a complete key-in-knob or key-in-lever cylinder, 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, and the Kaba Ilco 1539 Series is a universal key-in-knob/lever cylinder. The Kaba Ilco 1599 is a key-in-knob replacement cylinder.
12) Is the 488K99 plug the right part for an exit device or a rim application?
No. The 488K99 57C1 is a plug for Corbin Russwin CK4200, UT5200, and 2000-051 cylinder applications. Rim applications call for a rim cylinder: the Schlage 20-021 has a vertical tailpiece cam, the 20-022 a horizontal tailpiece cam, and the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Where a non-keyed rim fitting is needed, the BEST 12E Series dummy rim cylinder measures 1-5/32 inch in diameter.
13) The 488K99 57C1 takes 5 and 6 pins. What is available if I want a higher pin count or drill resistance?
The 488K99 57C1 X-Class plug is built to accept both 5-pin and 6-pin configurations in the 57C keyway. For a 7-pin, drill-resistant option in a different platform, the BEST 1CDF is a drill resistant patented interchangeable core with 7 pins in brass, 150 Series. Note it is an interchangeable core rather than a Corbin Russwin plug, so it is a hardware change, not a drop-in swap.
14) Can I use the 488K99 plug in a deadbolt?
The 488K99 57C1 is a plug for Corbin Russwin CK4200, UT5200, and 2000-051 cylinder applications, not a deadbolt cylinder. For deadbolt service the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and Medeco offers rim type lazy motion cylinders for handlesets and deadbolts including the 1075127 and 1065244 in 5-pin and the 1012040 in 6-pin for Kwikset single cylinder deadbolts.
15) Will the 488K99 57C1 work with an Adams Rite MS1847 deadlock?
No. The 488K99 57C1 plug is specified for Corbin Russwin CK4200, UT5200 (.552 inch), and 2000-051 cylinders. Adams Rite MS1847 deadlock and deadlatch openings are served by the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws; for a 5017 wood door deadlock the 4026 five pin tumbler cylinder pull is the wood door version.
