Corbin Russwin 487K11 27B1 626 – Frequently Asked Questions

1) What does the pin depth number mean on the 487K11 plug, and which do I need?
The pin depth code sets the master keying position of the plug within the system. Four are offered: 27, 57, 67 and 77. This is an individual X Class plug, meaning it is cut into a specific Corbin Russwin keying system, so the depth code has to come off your keying schedule or bitting list. Guessing it means the plug will not operate on the intended change key.
2) I need a whole mortise cylinder for a 1-1/8 inch prep, not just a plug. What should I order instead of the Corbin Russwin 487K11?
The Corbin Russwin 487K11 27B1 is a replacement cylinder plug, the keyed core barrel that goes into a Corbin Russwin mortise cylinder shell, not a complete cylinder. If the opening needs a full assembled mortise cylinder, the Detex MC65 is a complete 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway. The Adams Rite 4036 is another complete mortise cylinder, five-pin and Grade 1, for doors 1/2 inch thick and up. Choose the 487K11 only when the existing Corbin Russwin shell stays in the lock and you are rekeying or replacing the plug itself.
3) We want to rekey doors without pulling cylinders apart. What is the interchangeable core alternative to a mortise cylinder plug?
The Corbin Russwin 487K11 27B1 plug is pinned and installed into the cylinder shell, so rekeying means working on the cylinder itself. An interchangeable core system changes the keyed element with a control key instead. BEST offers the 1CB Peaks 150 Series interchangeable core and the 1C Series standard 5-pin core, and the 1CDF is a drill-resistant patented 7-pin brass core in the 150 Series. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the C keyway, 643E aged bronze. Those require housings prepped for interchangeable cores, so it is a system change rather than a drop-in for a Corbin Russwin mortise shell.
4) The cylinder I am replacing is in a key-in-lever lock, not a mortise lock. Is the 487K11 the right part?
No. The Corbin Russwin 487K11 27B1 plug is built for 1-1/8 inch mortise cylinder applications. For key-in-knob and key-in-lever cylinders, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder and the 1579 is a knob and lever cylinder for Sargent locks. The Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series with a 6-pin G keyway, keyed different with two cut keys. Confirm the lock chassis type before ordering, because the cylinder body shapes are not interchangeable.
5) Does the 487K11 plug work in both 5-pin and 6-pin Corbin Russwin cylinders?
Yes. The plug is drilled to accommodate both 5-pin and 6-pin configurations, so it can go into either build depending on the security level and keying depth of the system you are matching.
6) I manage a building with Corbin Russwin mortise locks. Is swapping plugs cheaper than replacing cylinders when a key goes missing?
Swapping the plug is the usual route on a Corbin Russwin system. Because the 487K11 is a plug and not a whole cylinder, you keep the shell, cam and mounting in the lock and only change the keyed component, which keeps the rest of the mortise lock untouched. It does require the new plug to match your keying schedule, so keep the system bitting on file. If the cylinder body itself is damaged or worn, replace the full cylinder instead.
7) I need a rim cylinder for an exit device, not a mortise plug. Is this the right part?
No. The 487K11 is a mortise cylinder plug, which threads into a mortise lock case, not a rim cylinder for an exit device. Rim cylinders mount through the door with a tailpiece. For that application look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam, or the 20-022 with a horizontal tailpiece cam, matched to the cam orientation your device needs.
8) Can I use a Schlage 20-021 rim cylinder in place of the Corbin Russwin 487K11 plug?
No. The Schlage Commercial 20-021 is a rim cylinder with a vertical tailpiece cam, supplied with two keys, and it mounts through the door behind a rim exit device. The Corbin Russwin 487K11 27B1 is a plug for a 1-1/8 inch threaded mortise cylinder in Corbin Russwin hardware. The 20-022 is the same rim cylinder with a horizontal tailpiece cam. Rim and mortise cylinders are different mounting types and neither substitutes for the other.
9) I need a keyed cylinder for a deadbolt. Does the Corbin Russwin 487K11 plug work there?
Not directly. The 487K11 27B1 is a mortise cylinder plug with a B keyway in 5-pin and 6-pin depths. For deadbolt applications, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the 1599 is a key-in-knob replacement cylinder, both listed with a deadbolt function. Medeco offers retrofit options as well: 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.
10) What should I use on an aluminum storefront with an Adams Rite deadlock instead of a Corbin Russwin mortise plug?
For Adams Rite MS1847 deadlock and deadlatch openings, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws, both intended for the MS1847. For a wood door with the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull applies. The Corbin Russwin 487K11 27B1 plug serves Corbin Russwin mortise cylinder assemblies in commercial lock systems and is not a storefront pull.
11) Will a Medeco retrofit cylinder replace the Corbin Russwin 487K11 in a mortise lock?
No. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the 1065244 is a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece. The Emtek CY4 is a single cylinder sold as a part for Emtek hardware. Those are matched to specific residential-style hardware, while the 487K11 27B1 is a commercial Corbin Russwin mortise cylinder plug in the X Class individual keying designation.
12) What finishes does the Corbin Russwin 487K11 plug come in, and does the finish have to match my cylinder?
Satin brass (606) and satin chrome (626) are the two options. The plug face is the visible part of the cylinder once installed, so match it to the existing cylinder ring and trim, 626 for brushed chrome and stainless looking hardware, 606 for brushed brass.
13) Is this plug suitable for a commercial or institutional facility?
Yes, it is a commercial-rated part. The 487K11 27B1 plug is used in office buildings, schools, hospitals, government facilities, retail and multi-tenant residential where Corbin Russwin mortise hardware is standardized across the openings.
14) We only need to fill a cylinder hole with no key function. Is there a blank option rather than the 487K11?
Yes. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and provides the cylinder appearance without key operation. The Corbin Russwin 487K11 27B1 is a keyed plug offered in B1 and B2 keyways with pin depths of 27, 57, 67 and 77 in 606 satin brass and 626 satin chrome, so it is the part to order when the opening is actually keyed.
