Corbin Russwin 487K21 67B1 626 – Frequently Asked Questions

1) Will the 487K21 plug work in my existing Corbin Russwin keying system?
It is cut for the 67B1 keyway, so it drops into an existing Corbin Russwin 67B1 program and can be pinned into a master key hierarchy. If your facility keys on a different Corbin Russwin keyway section, the 487K21 67B1 plug will not accept your keys and you need the plug in your own keyway.
2) Can I use the 487K21 in a 1-1/8 inch mortise cylinder housing?
No. The 487K21 plug is built for 2 inch mortise cylinder applications, and plug length has to match the housing. For a shorter commercial mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, or the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder.
3) If I need a complete mortise cylinder rather than just the plug, what should I order instead of the Corbin Russwin 487K21?
The 487K21 is a replacement cylinder plug for 2 inch mortise cylinders with the 67B1 keyway - it is the keyed core of the cylinder, not a whole cylinder body. If the existing cylinder shell is damaged or missing, order a complete mortise cylinder instead. The Detex MC65 is a mortise cylinder with a Schlage C keyway in 1-1/8 inch, 6-pin, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness. Both replace the whole cylinder; neither drops into a Corbin Russwin 67B1 keying program the way the 487K21 plug does.
4) Can a BEST interchangeable core be used in place of a Corbin Russwin 487K21 plug?
No. The 487K21 is a fixed 7-pin X Class plug that is pinned into a 2 inch Corbin Russwin mortise cylinder. BEST interchangeable cores such as the 1C Series standard 5-pin core, the Peaks 1CB 150 Series core, or the drill resistant 1CDF 7-pin brass 150 Series core are figure-eight cores that require an interchangeable-core housing and a control key to remove. They are a different servicing system, not a plug swap, so an opening would need IC housings throughout before those cores apply.
5) Does a 7-pin X Class plug mean I need restricted keys?
X Class is Corbin Russwin's higher key control pinning, and the 487K21 uses a 7-pin configuration built for restricted keyway and master keyed programs. Practically, that means keys are controlled rather than freely duplicated, which is why it turns up in schools, hospitals, and government buildings where key issue is tracked. You'll need blanks and cuts sourced through your Corbin Russwin key control program.
6) I just need a keyed cylinder for a rim exit device, not a mortise plug. What should I look at instead?
A plug won't help you there. For a rim device you want a rim cylinder: the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same with a horizontal cam. If you're standardizing on interchangeable cores, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
7) If I want to move away from keyed plugs to interchangeable cores, what are my options?
Interchangeable core lets you swap keying without pulling the cylinder, which a fixed 7-pin plug like the 487K21 does not. BEST offers the 1C Series standard 5-pin core, the Peaks 1CB 150 Series core, and the 1CDF drill resistant patented 7-pin brass core in the 150 Series. Schlage's 20-057-C is a full size interchangeable core in the C keyway, 643E Aged Bronze. Note that switching platforms means rekeying the building, not just changing a part.
8) We use rim exit devices on some doors - is the 487K21 plug the right part for those?
No. The 487K21 is built for 2 inch mortise cylinder bodies. Rim devices take a rim cylinder with a tailpiece: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal tailpiece cam, each supplied with 2 keys. If the facility runs full size interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to the device before ordering.
9) What is the difference between ordering the 487K21 plug and ordering a key-in-lever or key-in-knob cylinder?
They serve different lock bodies. The 487K21 is a 7-pin X Class plug for 2 inch Corbin Russwin mortise cylinders. Cylindrical locks take a knob or lever cylinder instead: the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, keyed different, supplied with 2 cut keys, and Kaba Ilco offers the 1539 Series universal key-in-knob/lever cylinder, the 1579 Series knob and lever cylinder for Sargent, and the 1599 Series key-in-knob replacement cylinder. None of these fit a mortise cylinder shell.
10) Our storefront doors have narrow stile deadlocks - does the 487K21 work there?
The 487K21 is a mortise cylinder plug in 2 inch format for Corbin Russwin mortise cylinders, so it is not the part for a narrow stile deadlock assembly. Adams Rite cylinder pulls cover that opening: the 4024 mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock and deadlatch.
11) I need a high security option for a deadbolt - is the 487K21 comparable to a Medeco retrofit cylinder?
Both address key control, but for different hardware. The 487K21 uses a 7-pin X Class configuration with the 67B1 keyway for restricted keying inside Corbin Russwin 2 inch mortise cylinders. Medeco retrofit cylinders are built for residential-style deadbolts and handlesets: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Choose by the lock body you are servicing.
12) Is this part suitable for residential doors or is it commercial only?
Commercial. The 487K21 is a commercial-grade mortise cylinder component, and it lands in office buildings, schools, healthcare, municipal buildings, retail, multi-tenant residential, and warehouses. For a house deadbolt or handleset you'd be looking at something like the Medeco 1075127 5-pin rim type lazy motion cylinder for handlesets and deadbolts instead.
13) What finishes does the 487K21 come in, and how does that compare with other cylinder options?
The 487K21 mortise cylinder plug is offered in 606 Satin Brass and 626 Satin Chrome. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze with a C keyway, which is a darker finish family if you are matching aged bronze trim rather than brass or chrome.
14) Is there a non-keyed cylinder part I can use where a door only needs the look of a cylinder?
The 487K21 is a keyed 7-pin X Class plug and always operates a key. Where an opening needs the appearance of a cylinder without key function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a rim prep without any keying. Note it is a rim format, so it does not fill a 2 inch mortise cylinder prep.
