Corbin Russwin 488K99 27A1 626 – Frequently Asked Questions

1) What keyway options are available on the Corbin Russwin 488K99 X-Class plug?
Both A1 and A2 keyways are offered. Both sit in the Corbin Russwin A keyway family, so the plug has to match the keyway already in use on the building's system or the existing keys will not enter. Pick the one that matches the key bitting record for that system.
2) Is the 488K99 a complete cylinder or just a replacement part?
Replacement part only. It is the individual plug for a Corbin Russwin cylinder, not a housing, cam or tailpiece. If you need a complete keyed cylinder for an exit device or a deadbolt, look at a full rim or mortise cylinder such as the Schlage 20-021 rim cylinder or the Adams Rite 4036 Grade 1 mortise cylinder instead.
3) Is a Corbin Russwin 488K99 plug the same thing as a complete replacement cylinder?
No. The Corbin Russwin 488K99 27A1 is an individual X-Class plug - the rotating pin tumbler core piece that drops into an existing CK4200, UT5200 (.552 inch) or 2000-051 cylinder housing, supplied in 5 and 6-pin form with an A keyway. If the housing itself is damaged or you need a whole assembly, you are looking at a complete cylinder instead, such as the Adams Rite 4036 mortise cylinder with five-pin security or the Detex MC65 mortise cylinder, a 1-1/8 inch 6-pin unit cut to the Schlage C keyway. Order the plug only when you are rebuilding or re-keying a housing that stays in the door.
4) If I want to move away from keyed plugs to an interchangeable core system, what replaces the 488K99?
An interchangeable core cylinder is the alternative approach. The 488K99 27A1 is a fixed X-Class plug that is pinned into a CK4200, UT5200 or 2000-051 housing, so re-keying means pulling and repinning the plug. With a small-format interchangeable core such as the BEST 1CB Peaks 150 Series core or the BEST 1C standard 5-pin core, the core is pulled with a control key. Schlage's full-size interchangeable core route uses the 20-057 FSIC rim cylinder with convertible tailpiece cam or the 20-057-C FSIC core in C keyway, 643E aged bronze. Switching systems means changing the housings and the key system, not just the plug.
5) Can I use a universal key-in-knob cylinder like the Kaba Ilco 1539 instead of the Corbin Russwin 488K99 plug?
They serve different jobs. The Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, a complete cylinder that replaces the whole cylinder in a knob or lever lock; the 1579 is the version built for Sargent locks and the 1599 is a key-in-knob replacement cylinder. The Corbin Russwin 488K99 27A1 is only the plug, sized for CK4200, UT5200 (.552 inch) and 2000-051 Corbin Russwin cylinder families in an A keyway. If the Corbin Russwin cylinder body stays in the lock and you are matching an existing A-keyway system, the 488K99 plug is the part; if you are replacing the cylinder outright on a non-Corbin lock, the Ilco units are the direction to look.
6) What is the .552 inch dimension on the UT5200 version?
The .552 inch figure is the UT5200 plug dimension the 488K99 is made to, which is what lets it drop into a UT5200 housing without machining. If the cylinder you are rebuilding is a UT5200, that dimension is the one that matters for fit.
7) I manage a building standardized on Corbin Russwin A keyway. Can I keep my existing keys if I rebuild cylinders with these plugs?
Yes, as long as you order the plug in the same keyway your system uses, A1 or A2, and pin it to your existing bitting. The plug carries the keyway and the pin chambers, so your current keys keep working and you stay inside the same controlled key interchange rather than starting a second system.
8) My opening uses an exit device with a rim cylinder, not a mortise housing. Is the 488K99 the right part?
No. The 488K99 27A1 X-Class plug fits Corbin Russwin CK4200, UT5200 (.552 inch) and 2000-051 cylinder families. For a rim application driven by a tailpiece cam, Schlage lists the 20-021 6-pin rim cylinder with vertical tailpiece cam and the 20-022 6-pin rim cylinder with horizontal tailpiece cam, each supplied with two keys; the cam orientation has to match what the device calls for. BEST also lists the 12E Series dummy rim cylinder at 1-5/32 inch diameter where a non-operating filler is needed.
9) We need a higher-security, drill-resistant option instead of a standard plug. What should we look at?
The Corbin Russwin 488K99 27A1 is a standard 5 and 6-pin X-Class plug for CK4200, UT5200 (.552 inch) and 2000-051 housings. For drill resistance and patented key control, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, 150 Series. Medeco's line covers retrofit high-security cylinders for residential-style hardware, including the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Moving to any of these changes the key system, so plan the rekey of the group before you order.
10) Will the 488K99 plug work in a storefront aluminum door deadlock?
Not as a direct fit. The 488K99 27A1 is dimensioned for Corbin Russwin CK4200, UT5200 (.552 inch) and 2000-051 cylinder families. Narrow-stile storefront work is served by Adams Rite parts: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for the MS1847 deadlock/deadlatch, the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch, and the 4036 Series mortise cylinder is a Grade 1 unit with a 1/2 inch minimum door thickness. Match the part to the deadlock model already in the stile.
11) I need a cylinder for a residential-style deadbolt or handleset, not a commercial lever. Is there a better fit than the 488K99?
Yes. The Corbin Russwin 488K99 27A1 is a commercial replacement plug for CK4200, UT5200 and 2000-051 cylinder families. For deadbolt and handleset work, Medeco lists the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 5-pin rim lazy motion cylinder with Emtek tailpiece, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder sold each. The tailpiece style is what decides the fit on those, so confirm it against the lock body.
12) Is this plug rated for commercial use or is it a residential part?
Commercial. The 488K99 is catalogued as a commercial Corbin Russwin cylinder part, the kind used in office buildings, schools, hospitals, government facilities and multi-tenant residential where a keyed system is being maintained across many doors.
