Corbin Russwin 488K99 27 626 – Frequently Asked Questions

1) Which Corbin Russwin keyways does the 488K99 X-Class plug work with?
The 488K99 plug is built for CK4200, UT5200 (.552 inch) and 2000-051 keyway systems. On the order side you pick the keyway number: 27, 67, 77, 97 or 99. Match the number to the section already in use on the building's key system, because a plug cut for one section will not accept keys from another.
2) Can the 488K99 plug be used in both 5-pin and 6-pin Corbin Russwin cylinders?
Yes. The plug accommodates 5-pin and 6-pin configurations, so one part number covers both chamber counts across the compatible Corbin Russwin cylinder assemblies. Pin it to whatever depth count your existing master key system is built on.
3) I need to rekey a Schlage or BEST cylinder, not Corbin Russwin. Will the 488K99 plug work?
No. The 488K99 is keyed to Corbin Russwin CK4200, UT5200 and 2000-051 keyway systems and will not fit other manufacturers' housings. For Schlage, a full size interchangeable core such as the Schlage 20-057 or the 20-057-C in C keyway is the right path; on a BEST small format system use a core like the BEST 1C5 5-pin core or the 1CB interchangeable core.
4) I need a whole cylinder, not just the plug - what should I order instead of the Corbin Russwin 488K99-27?
The 488K99-27 is a replacement cylinder plug, the pinned barrel that goes inside an existing Corbin Russwin cylinder housing for CK4200, UT5200 (.552 inch) and 2000-051 keyways - it is not a complete cylinder. If you need a full assembly, complete mortise and rim cylinders in the comparable range include the Adams Rite 4036 mortise cylinder with five-pin security, the Detex MC65 mortise cylinder in Schlage C keyway with a 1-1/8 inch length and 6 pins, and the Schlage 20-021 rim cylinder with a vertical tailpiece cam. Those ship as housings with plug and pins together, so no existing shell is required.
5) Can I use a BEST interchangeable core in place of the Corbin Russwin 488K99-27 plug?
No - they solve the same problem in different ways. The 488K99-27 is an individual X-Class plug pinned for Corbin Russwin CK4200, UT5200 and 2000-051 keyways and installed into an existing Corbin Russwin cylinder body. A BEST 1C5 standard 5-pin cylinder core or a BEST 1CB Peaks 150 Series interchangeable core drops into a BEST-prepped figure-eight core housing, not a Corbin Russwin shell. If the door already carries Corbin Russwin cylinders, the plug keeps the existing housings in service; converting to interchangeable cores means replacing the cylinder housings as well.
6) My opening is an exit device with a rim cylinder, not a Corbin Russwin mortise housing - what do I use?
The 488K99-27 X-Class plug serves existing Corbin Russwin cylinder assemblies on CK4200, UT5200 and 2000-051 keyways and does not by itself address a rim application. For rim prep, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 the same cylinder with a horizontal cam; 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 C keyway, 643E aged bronze. Match the cam orientation to what the exit device requires.
7) What finishes does the Corbin Russwin 488K99 plug come in, and will it match my existing cylinders?
Two finishes are offered: 606 satin brass and 626 satin chrome. Both are available in every keyway option (27, 67, 77, 97, 99). Since the plug face is the visible part in the keyhole, pick 626 to match satin chrome and brushed nickel hardware and 606 where the building is standardized on brass.
8) What does the .552 inch spec on the UT5200 keyway mean for fitment?
The .552 inch figure is the plug diameter specification for the UT5200 keyway system, and it is what determines whether the plug seats correctly in the cylinder housing. A housing bored for a different plug diameter will not take it, so confirm the cylinder you are servicing is a CK4200, UT5200 or 2000-051 family unit before pinning.
9) Is this X-Class plug suitable for a commercial master key system in a school or hospital?
Yes, it is a commercial-grade OEM part intended for exactly that kind of service work: rekeying and plug replacement in Corbin Russwin mechanical lock cylinders across offices, schools, healthcare, government and multi-tenant residential buildings. Because it ships as an unpinned individual plug, it lets a locksmith key it into the facility's existing X-Class master system rather than forcing a new key system.
10) Do I get pins, springs or keys with the 488K99 plug?
The 488K99 is the plug by itself, an individual X-Class plug supplied for cylinder service. Plan on supplying your own pinning kit and cutting keys to the system, unlike a factory-keyed cylinder such as the Schlage 20-021, which is listed as coming with two keys.
11) What looks like a substitute for the Corbin Russwin 488K99-27 but will not work?
Two traps. Cylinder pulls such as the Adams Rite 4024 with trim plate mounting and the 4025 five pin tumbler pull with through-screws are built for Adams Rite MS1847 deadlock and deadlatch systems, and the 4026 pull is for the Adams Rite 5017 wood door deadlock - they are door trim that accepts a cylinder, not a plug. The BEST 12E Series dummy rim cylinder at 1-5/32 inch diameter carries no working pinning at all. Neither substitutes for an X-Class plug pinned to a CK4200, UT5200 or 2000-051 keyway.
12) For a high-security spec, how does the Corbin Russwin 488K99-27 X-Class plug compare to a patented-key option?
The 488K99-27 is a commercial-grade X-Class plug intended for high-security keying applications on Corbin Russwin CK4200, UT5200 and 2000-051 systems, and it keeps a facility on its existing Corbin Russwin master key system. If the spec calls for a patented restricted key and drill resistance instead, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. That route changes the key system and the housing type; the X-Class plug preserves both.
