Corbin Russwin 487K13 77B2 626 – Frequently Asked Questions

1) Is the Corbin Russwin 487K13 a complete mortise cylinder or just the plug?
It's the plug only, not a complete cylinder. The 487K13 is a 7-Pin X Class replacement plug sized for 1-1/4 inch mortise cylinder applications, sold as an OEM replacement part for re-keying or restoring an existing Corbin Russwin mortise lock. If you need a whole cylinder to drop into a lock case, a plug won't do the job on its own. For a complete mortise cylinder, the Adams Rite 4036 five-pin Grade 1 mortise cylinder or the Detex MC65 (1-1/8 inch, 6-pin, Schlage C keyway) are full cylinders rather than internal parts.
2) Will the 487K13 plug work with my existing Corbin Russwin keys?
Only if your system is on the 77B2 keyway. This plug is cut for the 77B2 keyway, so keys from a different Corbin Russwin keyway will not enter it. On a master keyed building, match the keyway first, then pin the plug to your existing key bitting when you rebuild the cylinder.
3) Is a 7-pin plug going to fit a 6-pin Corbin Russwin cylinder housing?
No. Pin count has to match the housing. The 487K13 is a 7-Pin X Class plug built for 1-1/4 inch X Class mortise cylinders; a 6-pin housing takes a 6-pin plug. Count the chambers in the shell you're rebuilding before ordering.
4) Can I use the 487K13 in a rim cylinder or an exit device?
No. This is a mortise-format plug at 1-1/4 inch and it belongs in a mortise cylinder housing. Rim applications take a rim cylinder with a tailpiece, for example the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal cam, depending on how the device's cam is oriented.
5) The exit device takes a rim cylinder, not a mortise cylinder - what replaces the Corbin Russwin 487K13 there?
The 487K13 is sized for 1-1/4 inch mortise cylinder housings, so a rim application needs a rim cylinder. Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. If the opening is standardized on full size interchangeable cores, Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to the device.
6) Why choose an X Class plug over a standard Corbin Russwin plug?
Key control. The X Class plug design is specified for enhanced key control and pick resistance in commercial work, so blanks and duplicates stay restricted. That matters in schools, hospitals, offices and multi-tenant buildings where you don't want keys copied at a hardware store. If your existing cylinders are standard, a single X Class plug will not integrate with them; convert by keyway, not one door at a time.
7) I need to re-key a Corbin Russwin mortise lock. Do I need a new plug or can I reuse the old one?
You can re-pin an existing plug if the keyway and pin count stay the same. A new 487K13 plug is what you want when the old plug is worn, damaged, drilled, or when you're moving that cylinder onto the 77B2 keyway and a 7-pin X Class configuration. It's an OEM part cut to Corbin Russwin tolerances, so it seats in the 1-1/4 inch mortise shell without fitting.
8) What's the difference between this Corbin Russwin plug and an interchangeable core like the BEST 1C?
Different rekeying philosophy. The 487K13 is a plug you install inside a conventional 1-1/4 inch mortise cylinder shell, so rekeying means pulling and rebuilding the cylinder at the bench. An interchangeable core such as the BEST 1C Series 5-pin core or the 7-pin BEST 1CDF drill resistant patented core pops out with a control key and swaps in seconds, no disassembly. If you rekey often across a large portfolio, a core system saves labor; if you're maintaining existing Corbin Russwin mortise hardware, stay with the plug.
9) Can a Medeco retrofit cylinder be used where a Corbin Russwin 487K13 plug is called for?
No - the Medeco retrofit cylinders are built for specific residential-style hardware rather than commercial mortise shells. The 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Corbin Russwin 487K13 is a commercial 7-pin X Class plug for 1-1/4 inch mortise cylinder applications.
10) What is the simpler alternative if a facility does not need 7-pin X Class key control?
A five-pin cylinder is the plainer route. The BEST 1C5 is a standard 5-pin cylinder core, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder. The Corbin Russwin 487K13 differs in being a 7-pin X Class plug with the 77B2 keyway, intended to keep an existing Corbin Russwin keying system intact when a shell is re-keyed or restored.
11) For a keyed lever or knob rather than a mortise lock, what cylinder is used in place of the 487K13?
Key-in-lever and key-in-knob locks take their own cylinder format. The Falcon A23161-05 G is a key-in-lever cylinder for RU/T Series with a 6-pin G keyway, keyed different with two cut keys. Kaba Ilco offers the 1539 Series key-in-knob/lever universal cylinder and the 1579 Series knob and lever cylinder for Sargent locks. The Corbin Russwin 487K13, by contrast, is a plug for 1-1/4 inch mortise cylinder applications.
12) What looks like a cylinder substitute for the 487K13 but will not key a deadbolt?
A dummy cylinder. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and fills a cylinder hole without keyed function. For a keyed deadbolt you want a deadbolt cylinder such as the Kaba Ilco 1549 Series key-in-deadbolt cylinder or the 1599 Series key-in-knob replacement cylinder, both catalogued for deadbolt function. The Corbin Russwin 487K13 itself is a keyed 7-pin X Class plug for 1-1/4 inch mortise cylinders, not a deadbolt cylinder.
13) On an aluminum storefront with an Adams Rite deadlock, is the Corbin Russwin 487K13 the right part?
Only if the existing 1-1/4 inch Corbin Russwin mortise cylinder shell is being re-plugged, since the 487K13 is a replacement plug for that format. Where the storefront needs a cylinder pull, Adams Rite offers the 4024 with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws, both for the MS1847 deadlock/deadlatch; the 4026 is the five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock/deadlatch.
14) For standardizing a facility on removable cores instead of re-plugging cylinders, what is the alternative to the 487K13?
Interchangeable core hardware. The Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, finished 643E Aged Bronze, and BEST offers the 1CB Peaks 150 Series interchangeable core and the 1CDF 7-pin brass patented core. Those let a core be pulled with a control key. The Corbin Russwin 487K13 takes the other approach: a 7-pin X Class plug with the 77B2 keyway that re-keys an existing 1-1/4 inch mortise cylinder, available in 606 Satin Brass and 626 Satin Chrome.
15) What finishes does the Corbin Russwin 487K13 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder face and the rest of the trim on the door, since the plug face is the visible part around the keyway.
