Corbin Russwin 487K15 27A2 626 – Frequently Asked Questions

1) 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 7-pin X Class plug for a 1-3/8 inch mortise cylinder, sold as a replacement part rather than a whole cylinder body. If you need a full mortise cylinder assembly, the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder with a Schlage C keyway. Both are complete cylinders, so they carry their own keyway and will not key into a Corbin Russwin 27A2 system.
2) My exit device takes a rim cylinder, not a mortise cylinder. What do I order instead of the 487K15?
The Corbin Russwin 487K15 is a plug for a 1-3/8 inch mortise cylinder and will not serve a rim application. For rim devices, 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. If you want a keyed-removable core in the rim position, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Match the cam orientation to what your device requires.
3) For an aluminum storefront with an Adams Rite deadlock, is the Corbin Russwin 487K15 the right cylinder part?
No. The 487K15 is a 7-pin X Class plug for a 1-3/8 inch Corbin Russwin mortise cylinder. For Adams Rite storefront deadlocks, 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 MS1847, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock. The Adams Rite 4036 is the matching mortise cylinder, Grade 1 in the 4036 Series with a 1/2 inch minimum door thickness.
4) What does the 27A2 keyway mean for keying this plug into my building's master key system?
27A2 is the Corbin Russwin keyway this plug is cut for, so it will interchange only within an X Class keying system using that same keyway. For a facility standardizing on one system, that's the point: order all plugs in the same keyway and they key alike or master key together. Order a different keyway and the key won't enter.
5) Why choose a 7-pin X Class plug over a standard 6-pin cylinder for a commercial building?
Seven pins plus X Class keying gives you more key control, which matters where keys are issued to staff and unauthorized duplication is the real risk - schools, hospitals, government buildings, multi-tenant residential. A conventional 6-pin cylinder like the Detex MC65 in Schlage C is a much more common, openly available keyway, which is fine for a single opening but weak for controlling a fleet of doors.
6) If I want to be able to swap cores without a locksmith, is this plug the right approach?
No. A plug is rebuilt into the cylinder, so changing keying means pulling and repinning the cylinder. If you want field-swappable keying across a facility, go with an interchangeable core system instead: the BEST 1CB 150 Series interchangeable core or the 1CDF drill resistant 7-pin brass core, or Schlage's 20-057 full size interchangeable core.
7) I want a 7-pin option outside Corbin Russwin for higher key control. What else is 7-pin?
Within cylinders of this kind, the Corbin Russwin 487K15 plug is 7-pin X Class in a 1-3/8 inch mortise format with the 27A2 keyway. The other 7-pin option is the BEST 1CDF, a drill resistant patented interchangeable core in brass, 150 Series. The difference is format: the 487K15 rebuilds an existing Corbin Russwin mortise cylinder, while the 1CDF is a removable interchangeable core for BEST-prepped housings. Most other cylinders in this class are 5- or 6-pin, such as the Schlage 20-021 rim cylinder and the Falcon A23161-05 G six-pin G keyway lever cylinder.
8) What is the difference between the Corbin Russwin 487K15 plug and a Kaba Ilco replacement cylinder?
The 487K15 is a genuine Corbin Russwin 7-pin X Class plug that restores keying in a compatible 1-3/8 inch mortise cylinder. The Kaba Ilco line covers different lock types entirely: the 1539 Series is a key-in-knob and lever universal cylinder, the 1549 Series is a key-in-deadbolt cylinder, the 1579 fits Sargent knobs and levers, and the 1599 is a key-in-knob replacement cylinder. Choose an Ilco part when you are recylindering a knob, lever, or deadbolt; choose the 487K15 when the housing is a Corbin Russwin mortise cylinder.
9) I need a non-keyed cylinder for a dummy or inactive leaf. Can I use the 487K15?
The 487K15 is a keyed 7-pin X Class plug with the 27A2 keyway, intended to maintain key control in a working Corbin Russwin mortise cylinder. For an inactive or pull-only application where no key function is wanted, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is built for that purpose.
10) Does the Corbin Russwin 487K15 work in a residential handleset or deadbolt?
It is a commercial component, a 7-pin X Class plug for a 1-3/8 inch Corbin Russwin mortise cylinder. For residential handlesets and deadbolts, 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, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Emtek CY4 cylinder is also sold individually.
11) What finishes does the Corbin Russwin 487K15 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick to match the cylinder face and the lock trim on the rest of the opening - 626 Satin Chrome is the usual match for satin stainless and chrome lever trim, 606 for brass hardware.
12) Is this plug suitable for residential door hardware?
It's specified for commercial use, in commercial mortise lock assemblies. For a house, a key-in-knob or deadbolt cylinder is the usual part instead, such as the Kaba Ilco 1539 key-in-knob/lever universal cylinder or the 1549 key-in-deadbolt cylinder.
13) Can I match the satin chrome or satin brass on a 487K15 plug with a Schlage interchangeable core?
The Corbin Russwin 487K15 plug comes in 606 satin brass and 626 satin chrome. The Schlage 20-057-C is a full size interchangeable core in the C keyway supplied in 643E aged bronze, a darker finish, and it is an interchangeable core rather than a mortise cylinder plug, so it is not a finish match or a functional substitute for the 487K15.
