Corbin Russwin 487K13 27B1 626 – Frequently Asked Questions

1) Will the 487K13 plug work in a 1-1/8 inch mortise cylinder?
No. The 487K13 is built for 1-1/4 inch mortise cylinder housings. A 1-1/8 inch housing is a different length and the plug will not seat correctly. Measure the cylinder body from the face to the back before ordering - if you're working with a 1-1/8 inch six-pin mortise cylinder such as the Detex MC65, you need a cylinder sized to that housing instead.
2) Does the 27B1 keyway on this Corbin Russwin plug key into our existing building master system?
Only if your system is already on the 27B1 keyway. The plug is factory cut for 27B1, which is part of the Corbin Russwin keying system, so it will pin into an existing 27B1 masterkeyed system. If your facility runs a different Corbin Russwin keyway section, the keys won't enter this plug - match the keyway stamped on your current cylinders.
3) I need a whole mortise cylinder, not just the plug - what should I order instead of the Corbin Russwin 487K13?
The 487K13 27B1 is a replacement cylinder plug for 1-1/4 inch Corbin Russwin mortise cylinder housings, so it is the internal keyed component rather than a complete cylinder. If you need a full mortise cylinder assembly, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 series, and the Detex MC65 is a 6-pin commercial mortise cylinder in a 1-1/8 inch size with a Schlage C keyway. Note the diameter difference: the 487K13 plug is built for the 1-1/4 inch mortise format, while the MC65 is a 1-1/8 inch cylinder.
4) Would a BEST interchangeable core work in place of the Corbin Russwin 487K13 plug?
No - they solve the same maintenance problem in different ways. The 487K13 27B1 is a 7-pin X Class plug that drops into an existing Corbin Russwin 1-1/4 inch mortise cylinder housing and keeps keying inside the Corbin Russwin 27B1 system. A BEST interchangeable core such as the 1CB from the 150 series, or the 1CDF drill resistant patented 7-pin brass core, is removed and replaced with a control key and requires a housing prepped for BEST small format cores. If your doors are already on Corbin Russwin mortise cylinders, the 487K13 plug is the in-system part; converting to interchangeable cores is a hardware change, not a swap.
5) What is the difference between the Corbin Russwin 487K13 and a Schlage 20-021 rim cylinder?
Format. The 487K13 27B1 is a plug for a 1-1/4 inch mortise cylinder, which threads into a mortise lock body. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam - rim cylinders mount through the door behind a rim exit device or rim deadlock. Check which the door actually has before ordering; a rim cylinder will not serve a mortise housing.
6) Is this part suitable for a residential deadbolt rekey?
It's a commercial part. The 487K13 plug is specified for commercial Corbin Russwin mortise cylinder assemblies in offices, schools, healthcare, and multi-tenant buildings. For a residential knob or deadbolt rekey you'd want a replacement cylinder built for that lock - for example the Kaba Ilco 1549 key-in-deadbolt cylinder or the 1599 key-in-knob replacement cylinder.
7) We want interchangeable cores so we can rekey without pulling cylinders - is this the right direction?
No. A plug swap like the 487K13 means disassembling the mortise cylinder each time you rekey. If the goal is rekeying at the door in seconds, move to an interchangeable core platform instead: BEST 1CB 150 Series or the drill-resistant 1CDF 7-pin core, or Schlage's 20-057 6-pin FSIC rim cylinder. Those are a different keying system, so plan the changeover facility-wide rather than door by door.
8) Will this plug fit a rim cylinder or a key-in-lever cylinder?
No, it's a mortise plug only. The 487K13 is cut for 1-1/4 inch Corbin Russwin mortise cylinder bodies. Rim cylinders are a different body and cam arrangement - for those, look at the Schlage 20-021 vertical tailpiece or 20-022 horizontal tailpiece rim cylinders. Key-in-lever applications take something like the Falcon A23161-05 G 6-pin lever cylinder.
9) Does the 487K13 plug come with keys or pins?
The 487K13 is sold as the plug itself, a replacement component for Corbin Russwin mortise cylinder assemblies. Plan on supplying your own pinning and cutting keys to your 27B1 system. If you want a cylinder that arrives with keys, the Schlage 20-021 and 20-022 rim cylinders are listed as supplied with two keys.
10) I have a 5-pin system - is there a simpler alternative to the 7-pin Corbin Russwin 487K13?
The 487K13 27B1 is specifically a 7-pin X Class plug for Corbin Russwin 1-1/4 inch mortise cylinders, so the pin count is fixed with the part. For 5-pin commercial work, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the BEST 1C5 is a standard 5-pin cylinder core. Both are complete units rather than plugs, so they change what you are installing as well as the pin count.
11) Can the Corbin Russwin 487K13 plug be used to rekey a key-in-knob or lever lock?
No. The 487K13 27B1 is built for 1-1/4 inch Corbin Russwin mortise cylinder housings. Key-in-knob and lever locks take a different cylinder form: the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key in lever cylinder with a 6-pin G keyway supplied keyed different with 2 cut keys. Match the cylinder form to the lock body you are servicing.
12) For an aluminum storefront door, is the Corbin Russwin 487K13 the right cylinder part?
Only if the storefront lock already uses a Corbin Russwin 1-1/4 inch mortise cylinder, since the 487K13 27B1 is the plug that goes inside that housing. Narrow stile storefront hardware is often Adams Rite: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both made for the MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull suits the 5017 wood door deadlock/deadlatch. Identify the deadlock before choosing.
13) What finishes does the 487K13 cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one matching the cylinder face and the rest of the trim on the opening, since the plug face is visible at the keyway.
14) Does the Corbin Russwin 487K13 come in a chrome finish to match other hardware, or do I need a different brand?
The 487K13 27B1 plug is offered in 606 Satin Brass and 626 Satin Chrome, so both common commercial finishes are covered within the Corbin Russwin part itself. If you are matching a full interchangeable core instead, the Schlage 20-057-C is a full size interchangeable core cylinder with a C keyway in 643E Aged Bronze - a different keyway family and a different finish, so it is a coordination decision rather than a like-for-like finish swap.
15) I need a non-keyed cylinder for a pull-only door - is the 487K13 an option?
No. The 487K13 27B1 is a keyed 7-pin X Class plug, so it operates a lock. For a door that needs the look of a cylinder without function, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the non-functional part, and it is a rim format rather than a 1-1/4 inch mortise plug.
