Corbin Russwin 487K15 27B2 626 – Frequently Asked Questions

1) Does the 27B2 keyway mean my existing Corbin Russwin keys will work?
The plug is cut for the Corbin Russwin 27B2 keyway, so it accepts keys on a 27B2 system. It is a 7-pin X Class configuration, which is a restricted key control class. If the doors in your building are keyed on 27B2 in 7-pin, this plug drops into that system; if your existing cylinders are a different keyway or a 6-pin setup, the keys will not enter.
2) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 487K15?
The Corbin Russwin 487K15 is a replacement plug for 1-3/8" Corbin Russwin mortise cylinder housings, not a finished cylinder you can thread into a lock body. For a complete mortise cylinder, the Detex MC65 is a 1-1/8" 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Both are assembled cylinders rather than internal plugs, so they key to their own keyways instead of the Corbin Russwin 27B2 system.
3) Can a BEST interchangeable core be used in place of a Corbin Russwin 487K15 plug?
No. The 487K15 is a 7-pin X Class plug that fits inside a 1-3/8" Corbin Russwin mortise cylinder housing. BEST interchangeable cores, such as the 1CB 150 Series core or the 1CDF drill-resistant patented 7-pin brass core, are figure-eight cores that drop into BEST-prepped housings; the 1C5 is a standard 5-pin core in the same family. They serve the same purpose of changing keying without replacing the lock, but they are not dimensionally interchangeable with a Corbin Russwin mortise plug.
4) I need a cylinder for a rim exit device, not a mortise housing. What takes the place of the Corbin Russwin 487K15?
The 487K15 is sized for 1-3/8" mortise cylinder housings, so it will not serve a rim device. Rim applications call for a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Choose the cam orientation the exit device requires.
5) I need a complete mortise cylinder, not a plug. What else does ZenSupply carry?
For a full mortise cylinder rather than a rebuild part, look at the Adams Rite 4036 mortise cylinder, a five-pin Grade 1 unit with a 1/2 inch minimum door thickness, or the Detex MC65, a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Neither is on Corbin Russwin 27B2, so they suit a new or separate keying system rather than matching existing Corbin Russwin keys.
6) Can I use the 487K15 plug in a rim cylinder or an exit device?
No. This is a mortise-format plug for 1-3/8 inch mortise cylinder bodies. Rim cylinders use a different body and tailpiece arrangement entirely. For rim applications, the Schlage 20-021 six-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal cam are the parts to look at, and the BEST 12E Series dummy rim cylinder covers a non-keyed rim opening.
7) If I want interchangeable cores instead of rebuilding fixed cylinders, what should I be looking at?
The 487K15 is a fixed-cylinder plug, so every re-key means pinning the plug. If you would rather pull and swap cores on a facility, the BEST 1C Series five-pin core, the 1CB Peaks 150 Series core, or the drill-resistant 1CDF seven-pin brass core are interchangeable-core options. Schlage's 20-057 FSIC rim cylinder with a convertible tailpiece cam is another route. Moving to IC means changing cylinder housings, not just plugs.
8) Can I re-key a Corbin Russwin mortise lock without replacing the whole lock?
That is exactly what this part is for. Swapping the 487K15 plug lets you change the keying on a 1-3/8 inch Corbin Russwin mortise cylinder while the lock body, trim and prep stay in the door. Useful for tenant turnover or a compromised key, and it keeps the opening's existing hardware intact.
9) What is the difference between the Corbin Russwin 487K15 and a full size interchangeable core like the Schlage 20-057-C?
The 487K15 is a 7-pin X Class plug supplied as a replacement part for Corbin Russwin mortise cylinder assemblies, so re-keying is done at the plug level inside an existing housing. The Schlage 20-057-C is a full size interchangeable core in the C keyway with a 643E Aged Bronze finish, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. FSIC cores are pulled and swapped with a control key rather than serviced as an internal plug.
10) Is the Corbin Russwin 487K15 the right part for a key-in-lever or deadbolt cylinder replacement?
No. The 487K15 is a mortise cylinder plug in the Corbin Russwin 27B2 keyway. For key-in-knob and key-in-lever work, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder and the 1579 Series is a knob and lever cylinder for Sargent; for deadbolts, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway, keyed different with two cut keys.
11) What looks like a substitute for the Corbin Russwin 487K15 but is not a keyed cylinder part at all?
Watch for two categories. The BEST 12E Series dummy rim cylinder with a 1-5/32" diameter is a non-functioning cylinder used for appearance and trim only, so it cannot be keyed into a 27B2 system the way the 487K15 can. Cylinder pulls are also distinct hardware: the Adams Rite 4024 mounts with a trim plate for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler pull for the 5017 wood door deadlock. Those are pull assemblies for specific Adams Rite locks, not mortise cylinder plugs.
12) My spec calls for a Grade 1 cylinder. Does the Corbin Russwin 487K15 satisfy that, or should I look elsewhere?
The 487K15 is a commercial-grade 7-pin X Class plug for Corbin Russwin 1-3/8" mortise cylinders, offered in 606 Satin Brass and 626 Satin Chrome. If the drawing calls out a Grade 1 mortise cylinder as a complete assembly, the Adams Rite 4036 mortise cylinder is stated as Grade 1 in the 4036 Series with a 1/2" minimum door thickness, which gives you a graded assembly to cite against the spec.
13) What finishes does the Corbin Russwin 487K15 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the face of the cylinder ring and the lever or knob trim on the opening, since the plug face is the visible part once the cylinder is assembled.
14) Is this plug suitable for a school or hospital keying system?
Yes. The 487K15 is a commercial-grade part, and the 7-pin X Class arrangement is built for facilities that run master key systems needing key control and security differentiation. Corbin Russwin lists office buildings, schools, healthcare, government, multi-tenant residential, retail and industrial as typical settings for this class of cylinder component.
15) For residential handlesets and deadbolts, what cylinder should I look at rather than the Corbin Russwin 487K15?
The 487K15 is a commercial-grade mortise cylinder plug. For handleset and deadbolt retrofits, Medeco offers rim-type lazy motion cylinders: the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. The Emtek CY4 cylinder is sold individually as a parts item.
