Corbin Russwin 487K21 67A2 626 – Frequently Asked Questions

1) Will the 487K21 plug work in my existing Corbin Russwin keying system?
It's cut for the 67A2 keyway, so it drops into a Corbin Russwin 67A2 keying system and keeps existing key control. If your building is keyed on a different Corbin Russwin keyway, this plug will not accept those keys and you need the matching keyway version instead.
2) Can I use this plug in a rim cylinder or a key-in-lever cylinder?
No. The 487K21 is sized for 2 inch mortise cylinders. For rim applications you'd look at a rim cylinder such as the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam); for a key-in-knob or lever replacement, the Kaba Ilco 1599 is the knob-cylinder route.
3) We standardize on interchangeable cores. Is the 487K21 an IC core?
No, it's a fixed 7-pin plug for a 2 inch Corbin Russwin mortise cylinder, not a removable core. If you want small-format interchangeable core so maintenance can rekey by swapping cores, look at the BEST 1CB 150 Series interchangeable core or the BEST 1CDF drill-resistant 7-pin core; for full-size interchangeable core, the Schlage 20-057 FSIC rim cylinder.
4) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 487K21?
The 487K21 is a 7-pin X Class cylinder plug for 2 inch mortise cylinders - a replacement component that goes into an existing Corbin Russwin mortise cylinder body, not a finished cylinder. If the opening needs a whole mortise cylinder, the Detex MC65 is a mortise cylinder with a Schlage C keyway in a 1-1/8 inch 6-pin commercial configuration, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1. Those two ship as complete cylinders; the 487K21 restores or rekeys one you already have.
5) Can I use the Corbin Russwin 487K21 plug in a rim cylinder application?
No. The 487K21 plug is built for 2 inch mortise cylinder bodies, which thread into a mortise lock case. Rim devices take a rim cylinder instead - for example the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam, or the 20-022 with a horizontal tailpiece cam. Choose the tailpiece orientation your exit device or rim lock requires.
6) I need a cylinder for a key-in-lever lock, not a mortise case. What is the right part?
The 487K21 plug fits 2 inch mortise cylinders and will not serve a key-in-lever lock. For lever and knob locks, look at the Kaba Ilco 1539 key-in-knob and lever universal cylinder, the Kaba Ilco 1579 knob and lever cylinder for Sargent, the Kaba Ilco 1599 key-in-knob replacement cylinder, or the Falcon A23161-05 G key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys. For deadbolts specifically, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
7) Why choose a 7-pin plug over a 5- or 6-pin?
The 7-pin X Class configuration gives tighter key control and more security than standard 5- or 6-pin plugs, which is why it shows up in facilities running restricted keying. It also means the plug is not interchangeable with a 6-pin build, for example the Schlage 20-021 rim cylinder or the Detex MC65, both 6-pin. Pin count has to match the system you are servicing.
8) How does the 487K21 7-pin plug compare with an interchangeable core if I want to rekey doors quickly?
The 487K21 is a plug that is serviced inside the cylinder - the 7-pin X Class configuration gives key control beyond standard 5- or 6-pin plugs, but changing it is a bench operation. An interchangeable core system swaps keying at the door instead: the BEST 1CB is a 150 series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those require a housing prepped for cores; the 487K21 keeps an existing Corbin Russwin mortise cylinder in service.
9) Will the Corbin Russwin 487K21 work in an Adams Rite storefront deadlock setup?
The 487K21 is keyed to the 67A2 keyway and built for compatible Corbin Russwin mortise lock assemblies, so it is not the part for an Adams Rite storefront system. Adams Rite MS1847 deadlock and deadlatch installations use the 4024 cylinder pull with trim plate mounting or the 4025 five pin tumbler cylinder pull with through-screws, and the 4026 five pin tumbler cylinder pull covers Adams Rite 5017 wood door deadlocks. The Adams Rite 4036 five-pin mortise cylinder is the mortise cylinder within that family.
10) What cylinder should I use for a residential handleset or deadbolt retrofit instead of the 487K21?
The 487K21 is a commercial mortise cylinder plug, so for handleset and deadbolt retrofits the Medeco range fits better: the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
11) Is this plug suitable for high-traffic commercial doors, or is it a residential part?
Commercial. Corbin Russwin classifies the 487K21 for commercial use, and it is used on office, school, healthcare, government, retail, warehouse and multi-tenant residential openings. It is a genuine Corbin Russwin cylinder component, so fit and function match original equipment on compatible mortise lock assemblies.
12) Is there a simpler lower-pin option than the 487K21 7-pin X Class plug?
The 487K21 uses a 7-pin X Class configuration for tighter key control than standard 5- or 6-pin builds, and it stays within Corbin Russwin 67A2 keying. If the facility does not need that level of key control, 5-pin and 6-pin cylinders exist in other families - the BEST 1C5 is a standard 5-pin core, the Adams Rite 4036 is a five-pin mortise cylinder, and the Detex MC65 is a 6-pin mortise cylinder. Moving to any of those means leaving the 67A2 keying system, so confirm the master key plan first.
13) I need the plug in satin chrome rather than satin brass - and does a chrome-toned peer exist if I switch families?
The 487K21 plug is offered in 606 satin brass and 626 satin chrome, so a finish change is handled within the same part. If you end up switching to an interchangeable core instead, the Schlage 20-057-C is a full size interchangeable core with a C keyway in 643E aged bronze, which is a darker tone than either 487K21 finish.
