Corbin Russwin 487K13 57B1 626 – Frequently Asked Questions

1) Will the 487K13 plug work in my Corbin Russwin mortise cylinder if my system uses a different keyway?
No. The plug is cut for the 57B1 keyway, so it only accepts keys in that profile. A plug in the wrong keyway will not take your existing keys and will break your master key system. Confirm the keyway stamped on your current cylinder before ordering, and order the matching keyway plug if it is not 57B1.
2) I need a complete mortise cylinder, not a plug. What else do you carry?
For a full mortise cylinder, the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder rated for doors 1/2 inch minimum thickness, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in the Schlage C keyway. Note the difference in diameter: the 487K13 plug is for 1-1/4 inch mortise housings, while the MC65 is a 1-1/8 inch body, so they are not interchangeable in the same prep.
3) Will a mortise cylinder plug like this fit a rim cylinder or a key-in-lever lock?
No. Mortise and rim cylinders are different bodies with different cams and tailpieces, and a key-in-lever lock takes its own cylinder format entirely. For rim applications the Schlage 20-021 six-pin rim cylinder with vertical tailpiece cam or the 20-022 with horizontal cam are the right parts. For key-in-knob or lever replacement, the Kaba Ilco 1539 universal knob/lever cylinder or the Falcon A23161-05 G six-pin G keyway key-in-lever cylinder fit that job.
4) I need a complete mortise cylinder, not just a plug — what should I order instead of the Corbin Russwin 487K13?
The 487K13 is a replacement plug for 1-1/4 inch mortise cylinder housings, so it only helps if you already have the cylinder shell and are rebuilding or rekeying it. If you need a whole mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder with a Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder in the 4036 series. Both arrive as complete cylinders rather than a plug you pin and install into an existing housing.
5) My opening uses a rim device, not a mortise housing — is the 487K13 the right part?
No. The 487K13 plug is dimensioned for 1-1/4 inch mortise cylinder housings. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The cam orientation is dictated by the exit device you are keying, so confirm which your device takes before ordering.
6) We want cores we can swap without disassembling the cylinder — what is the alternative to a pinned plug like the 487K13?
The 487K13 is a 7-pin X Class plug that is pinned into a mortise housing, so rekeying means pulling and repinning the plug. If your goal is field-swappable keying, look at interchangeable core products instead: the BEST 1CB is a 150 series interchangeable core, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in brass, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those let a control key remove the core in seconds, at the cost of moving the whole facility onto an IC platform.
7) What does the X Class 7-pin designation mean for key control in a school or hospital?
X Class is Corbin Russwin's higher security keying classification, and it runs seven pins rather than the more common five or six. That means restricted keyway access and tighter pick resistance, which is what facilities running a disciplined master key system want. It also means keys and plugs are controlled: you cannot substitute a standard-keyway plug into an X Class system and keep the hierarchy intact.
8) Can I use this instead of an interchangeable core to rekey doors quickly?
No, a plug swap is a bench operation on a conventional mortise cylinder, not a tool-free core change. If your goal is fast field rekeying, look at an interchangeable core system instead: the BEST 1CB Peaks 150 Series IC cylinder, the BEST 1CDF drill-resistant patented 7-pin brass core, the BEST 1C five-pin standard core, or Schlage's 20-057 six-pin FSIC rim cylinder and the 20-057-C FSIC core in the C keyway. Those pull and replace with a control key.
9) Do keys come with the 487K13 plug?
The 487K13 is supplied as a cylinder plug component only, so plan on having keys cut to your system by your locksmith or the factory key records. If you want a cylinder that ships with keys, the Schlage 20-021 and 20-022 rim cylinders each come with two keys, and the Falcon A23161-05 G comes keyed different with two cut keys.
10) What is the difference between the 487K13 7-pin X Class plug and a standard 5-pin core?
The 487K13 uses a seven-pin tumbler arrangement with the X Class designation and the 57B1 keyway, which Corbin Russwin uses for restricted key control and added pick resistance. A standard 5-pin product such as the BEST 1C5 core has two fewer pin chambers and correspondingly fewer key differs, which matters when you are expanding a master key system rather than just replacing one cylinder. The Adams Rite 4026 and 4025 cylinder pulls are likewise five pin tumbler designs.
11) I have an aluminum storefront with an Adams Rite deadlock — can I use the 487K13 plug there?
That is a different platform. The 487K13 is a commercial mortise cylinder plug in 1-1/4 inch format. Adams Rite narrow stile deadlocks are served by dedicated parts: the 4024 cylinder pull 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 same MS1847, and the 4026 five pin tumbler pull is built for the 5017 wood door deadlock and deadlatch.
12) Is the Corbin Russwin 487K13 a substitute for a residential deadbolt or handleset cylinder?
No. The 487K13 is specified for commercial applications as a mortise cylinder plug. Residential deadbolt and handleset retrofits are covered by different parts: the Medeco 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.
13) Is the 487K13 suitable for commercial buildings, or is it a residential part?
Commercial. Corbin Russwin lists it as a commercial-grade cylinder component, typically used in office buildings, schools, healthcare and government facilities, multi-tenant residential, retail and warehouse properties. Property managers standardizing a building on one keyway will keep a stock of these plugs so a compromised key can be cut out of the system door by door.
14) I need a cylinder that fills the hole but does not have to be keyed — what instead of the 487K13?
The 487K13 is a functioning 7-pin plug meant to be pinned to a 57B1 keying system, so it is more part than you need for a blank opening. A dummy unit covers that case: the BEST 12E series dummy rim cylinder has a 1-5/32 inch diameter and provides the appearance and hole fill without keyed operation. Confirm the prep diameter on the door before substituting, since the 487K13 is dimensioned for 1-1/4 inch mortise housings.
15) Does finish choice affect which cylinder part I can cross-reference for the 487K13?
The 487K13 plug comes in 606 satin brass and 626 satin chrome, so the plug face can be matched to existing trim on either a brass or chrome opening. Cross-brand parts are not always offered in the same two finishes; the Schlage 20-057-C full size interchangeable core, for example, is a C keyway core in 643E aged bronze. If finish continuity across a floor matters, verify the finish code on the substitute rather than assuming the platform offers it.
16) What should I use for an Emtek opening rather than the Corbin Russwin 487K13?
The 487K13 keys into Corbin Russwin 57B1 systems and is a 1-1/4 inch mortise plug, so it will not serve Emtek trim. Emtek openings are covered by the Emtek CY4 cylinder, sold each, and by the Medeco 1065244, a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece for when you want the opening on a Medeco key system.
