Corbin Russwin 487K19 27A2 626 – Frequently Asked Questions

1) What keyway does the Corbin Russwin 487K19 plug come in, and will it work with my existing keys?
The plug is cut for the 27A2 keyway, a Corbin Russwin profile. It will accept keys from a 27A2 system once it's pinned to your combination. If your building is keyed to a different Corbin Russwin section, or to a Schlage or BEST keyway, this plug is the wrong part; the keyway has to match the system you're maintaining.
2) Will the 487K19 plug fit a rim cylinder or a key-in-knob cylinder?
No. It is built for 1-3/4 inch mortise cylinder housings and will not serve a rim or key-in-lever application. For rim work, look at a rim cylinder such as the Schlage 20-021 (6-pin, vertical tailpiece cam) or 20-022 (horizontal tailpiece cam). For a key-in-knob or lever replacement, the Kaba Ilco 1599 key-in-knob replacement cylinder is the type you want.
3) I'm rekeying mortise locks across a commercial building. Can I use this plug instead of buying whole cylinders?
Yes, that's exactly its purpose. Swapping the plug in an existing 1-3/4 inch Corbin Russwin mortise housing keeps the housing, cam, and ring in place and changes only the keying core, which is faster and cheaper than replacing complete cylinders across a facility. It's a genuine Corbin Russwin cylinder part built for commercial mechanical lock work, so the housings you already have stay in service.
4) I need a complete mortise cylinder, not just a plug — what should I order instead of the Corbin Russwin 487K19?
The Corbin Russwin 487K19 27A2 is a replacement cylinder plug, a part that goes into an existing mortise housing rather than a whole cylinder. If you need a complete mortise cylinder assembly, the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1, and the Detex MC65 is a 6-pin mortise cylinder with a Schlage C keyway in the 1-1/8 inch size. Those are full cylinders you thread into the lock body; the 487K19 only replaces the keyed plug inside a Corbin Russwin housing.
5) Can I use a Schlage 20-021 or 20-022 rim cylinder in place of the Corbin Russwin 487K19?
No. The Schlage Commercial 20-021 and 20-022 are rim cylinders, mounted through the door behind a rim device with a tailpiece cam — the 20-021 uses a vertical tailpiece cam and the 20-022 a horizontal one. The Corbin Russwin 487K19 27A2 is a 7-pin plug for a 1-3/4 inch mortise cylinder format, so it neither fits a rim prep nor substitutes for a rim cylinder.
6) I have a Sargent or Schlage key-in-lever lock to re-key — does the Corbin Russwin 487K19 fit?
No. The 487K19 27A2 plug is built to Corbin Russwin specifications for the 1-3/4 inch mortise cylinder format and the 27A2 keyway. For key-in-knob and key-in-lever bodies, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Kaba Ilco 1539 is a universal key-in-knob/lever cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys.
7) What does 7-pin X Class mean on a Corbin Russwin cylinder plug?
X Class is Corbin Russwin's high-security pin-tumbler platform, and this plug uses a 7-pin configuration for tighter key control than a standard 5- or 6-pin plug. More pin positions mean more usable combinations in a master key system, which matters on a large campus or multi-building masterkey. A 7-pin plug also has to be pinned with 7-pin hardware and keyed on the matching X Class system.
8) Is a 7-pin plug interchangeable with the 6-pin cylinders already in my doors?
Not as a keying match. A 7-pin X Class plug belongs to a 7-pin system and won't key alongside 6-pin cylinders such as the Detex MC65 (Schlage C keyway, 6-pin) or the Falcon A23161-05 G 6-pin G keyway cylinder. Keep the pin count and keyway consistent across the openings you want on one key.
9) We want to standardize on interchangeable cores instead of replacing plugs one at a time — what are the options?
Replacing the keyed plug, as with the Corbin Russwin 487K19 27A2, means the housing stays in the door and the plug is swapped. An interchangeable-core approach instead pulls the whole core with a control key: the BEST 1CB is a 1CB Series interchangeable core cylinder in the 150 Series, the BEST 1CDF is a drill-resistant patented 7-pin brass interchangeable core in the 150 Series, and the Schlage 20-057-C is a full size interchangeable core in the C keyway with a 643E Aged Bronze finish. Those change the keying platform, so they are a system decision rather than a drop-in for a Corbin Russwin mortise housing.
10) Is a BEST 1C5 core the same kind of part as the Corbin Russwin 487K19 plug?
They are both the keyed element rather than the full cylinder, but they are not interchangeable. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, made to drop into a BEST figure-eight core housing. The Corbin Russwin 487K19 27A2 is a 7-pin X Class plug cut for the 27A2 keyway and the 1-3/4 inch Corbin Russwin mortise format.
11) For an aluminum storefront with an Adams Rite deadlock, do I use the 487K19 or something else?
Use the Adams Rite parts. The 4024 cylinder pull mounts with a trim plate and the 4025 five-pin tumbler cylinder pull mounts with through-screws, both made for the Adams Rite MS1847 deadlock/deadlatch; the 4026 five-pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch. The Corbin Russwin 487K19 27A2 is a 7-pin plug for a Corbin Russwin 1-3/4 inch mortise cylinder housing.
12) Which cylinders in this family ship with keys, and does the 487K19?
The Corbin Russwin 487K19 27A2 is a replacement plug in the 27A2 keyway, keyed into your existing Corbin Russwin system rather than supplied as a keyed-different assembly. By contrast the Schlage 20-021 and 20-022 rim cylinders and the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam each come with 2 keys, and the Falcon A23161-05 G is keyed different with 2 cut keys.
13) What is the difference between a 7-pin plug like the 487K19 and a 5-pin cylinder for key control?
Pin count drives how many differs a keying system can carry. The Corbin Russwin 487K19 27A2 uses a 7-pin X Class plug configuration in the 27A2 keyway, and the BEST 1CDF is likewise a 7-pin interchangeable core, described as drill resistant and patented. Five-pin options such as the Adams Rite 4036 mortise cylinder and the BEST 1C5 core work on shorter bitting, which suits smaller keying schedules.
14) What kinds of buildings is the Corbin Russwin 487K19 plug meant for?
It's a commercial part, aimed at office buildings, schools, healthcare, government and municipal facilities, retail, industrial and warehouse space, and multi-tenant residential. Anywhere a facility already runs Corbin Russwin mortise locks and needs rekeying or key-control upgrades without replacing lock bodies.
15) Is there a non-keyed option if I only need to fill the cylinder hole?
The Corbin Russwin 487K19 27A2 is a keyed 7-pin plug and always operates with a key. If an opening needs a cylinder present but no keyed function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter serves that purpose on a rim prep. It is a dummy, so it provides no key control at all, unlike the 7-pin X Class plug.
16) What are the finish choices on the Corbin Russwin 487K19 compared with a Schlage FSIC core?
The Corbin Russwin 487K19 27A2 plug comes in 606 Satin Brass and 626 Satin Chrome. The Schlage 20-057-C full size interchangeable core is offered in 643E Aged Bronze, so if you are matching darker trim the two lines land in different finish families.
17) Is there a simpler part number if I just need a generic cylinder for an Emtek or deadbolt-style lock?
Yes. The Emtek CY4 is a cylinder sold each under the Parts line, and the Kaba Ilco 1549 is a key-in-deadbolt cylinder while the Kaba Ilco 1599 is a key-in-knob replacement cylinder. Those are simpler, non-mortise replacements; the Corbin Russwin 487K19 27A2 is specific to the 1-3/4 inch Corbin Russwin mortise cylinder format and the 27A2 keyway.
