Corbin Russwin 487K11 AR 626 – Frequently Asked Questions

1) What keyway does the Corbin Russwin 487K11 AR plug use, and will my existing keys work?
The plug is cut for the AR keyway. Keys and blanks in an AR keyway system will enter it once it's pinned to your bitting. If your building is keyed to a different Corbin Russwin section, an AR plug won't accept those keys, so match the keyway on the cylinder you're rebuilding before ordering.
2) Can I use this Corbin Russwin plug to rekey cylinders from another brand?
No. The 487K11 AR is a genuine Corbin Russwin component machined to fit Corbin Russwin mortise cylinder assemblies. It is not a cross-brand part. For Schlage openings, Schlage's own cylinders such as the 20-021 rim cylinder are the right family; for BEST interchangeable core housings you'd use a core like the BEST 1C 5-pin standard core.
3) If I need a complete 1-1/8" mortise cylinder rather than just a replacement plug, what should I order?
The Corbin Russwin 487K11 AR is a 5 and 6-pin individual X Class plug for 1-1/8" mortise cylinder applications, sold as a replacement part rather than a full cylinder assembly. When the whole cylinder body is needed, the Detex MC65 is a 1-1/8" 6-pin mortise cylinder in a Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1. Those two are complete mortise cylinders keyed to their own keyways, so they would not stay in a Corbin Russwin AR master key system the way the 487K11 AR plug does.
4) Is a BEST interchangeable core a substitute for the Corbin Russwin 487K11 AR plug?
No. The 487K11 AR is an individual X Class plug in the AR keyway that goes into a Corbin Russwin 1-1/8" mortise cylinder housing and is keyed as part of that conventional cylinder. BEST interchangeable cores are a different system: the 1C Series standard 5-pin cylinder core, the 1CB 150 Series interchangeable core, and the 1CDF drill resistant 7-pin brass 150 Series core all drop into BEST-style IC housings and are removed with a control key. If the door has a conventional Corbin Russwin mortise cylinder, the plug is the part that matches it; if the facility is standardized on interchangeable cores, one of the BEST cores fits that program instead.
5) My exit device takes a rim cylinder, not a mortise cylinder. What do I use instead of the 487K11 AR?
The Corbin Russwin 487K11 AR is sized for 1-1/8" mortise cylinder housings, so it will not serve a rim application. For rim prep, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, which covers either cam orientation from one part. Check which cam orientation the device calls for before ordering.
6) Does the 487K11 mortise cylinder plug come in anything besides satin brass?
Two finishes: 606 satin brass and 626 satin chrome. Pick the one that matches the cylinder face and the rest of the trim on the opening, since the plug face shows at the keyhole.
7) Is this plug suitable for commercial master key systems in schools and hospitals?
Yes. It's rated for commercial use and is built for master keying work, with 5- and 6-pin capability in the AR keyway. Typical use is office buildings, schools, healthcare, government buildings, retail, multi-tenant residential, and industrial facilities where a locksmith is rebuilding or rekeying Corbin Russwin mortise cylinders in-house.
8) I need a mortise cylinder for an aluminum storefront door, not a plug. What should I look at?
A plug like the 487K11 won't help you there. For narrow stile aluminum work, the Adams Rite 4036 mortise cylinder is a five-pin Grade 1 cylinder that suits doors from 1/2 inch minimum thickness. If the opening uses an MS1847 deadlock and you need a cylinder pull, the Adams Rite 4024 or 4025 are made for that lock.
9) What is the equivalent part if I am replacing the cylinder in a key-in-knob or key-in-lever lock instead of a mortise lock?
The Corbin Russwin 487K11 AR is a mortise cylinder plug and does not fit knob or lever cylinder cavities. For key-in-knob and key-in-lever work, the Kaba Ilco 1539 Series is a universal key-in-knob/lever cylinder, the 1579 Series is a knob and lever cylinder built for Sargent locks, and the 1599 Series is a key-in-knob replacement cylinder. Falcon also offers the A23161-05 G key-in-lever cylinder, a RU/T Series 6-pin G keyway unit supplied keyed different with two cut keys.
10) For a deadbolt or handleset cylinder swap, is the Corbin Russwin 487K11 AR the right part?
No. The 487K11 AR is a plug for 1-1/8" Corbin Russwin mortise cylinders. Deadbolt and handleset retrofits call for a purpose-built cylinder: the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. Match the part to the lock brand and tailpiece style already in the door.
11) I need a cylinder pull for an aluminum storefront deadlock. Does the 487K11 AR cover that?
No. The Corbin Russwin 487K11 AR is a mortise cylinder plug, not a pull. For storefront deadlock openings, the Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems and the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock. For wood doors, the Adams Rite 4026 five pin tumbler cylinder pull is built for the 5017 wood door deadlock. The choice between 4024 and 4025 comes down to trim plate mounting versus through-screw mounting.
12) What is the difference between the 487K11 AR and a dummy cylinder?
The Corbin Russwin 487K11 AR is a working 5 and 6-pin X Class plug in the AR keyway, pinned to operate a key within a 1-1/8" mortise cylinder. The BEST 12E Series dummy rim cylinder with a 1-5/32" diameter is a non-functioning cylinder used to fill a prep where no keyed operation is wanted. If the door needs key control, the 487K11 AR plug is the keyed component; if the opening only needs the hole covered with matching hardware, the dummy is the part.
13) If my facility is standardizing on full size interchangeable core in a Schlage C keyway, what replaces a Corbin Russwin AR plug?
The 487K11 AR plug is keyed to the Corbin Russwin AR keyway, so it stays inside an AR-keyed program. A facility moving to Schlage C keyway full size interchangeable core would look at the Schlage 20-057-C, a full size interchangeable core in the C keyway supplied in 643E Aged Bronze. The 487K11 AR is finished in 606 Satin Brass or 626 Satin Chrome, so appearance as well as keyway changes when switching between the two approaches.
14) Is the Corbin Russwin 487K11 AR appropriate for residential handleset work?
The 487K11 AR is specified for commercial applications as a Corbin Russwin cylinder replacement part. For residential-style handleset and decorative trim, the Emtek CY4 cylinder is sold each as an Emtek part, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Those match residential trim platforms, while the 487K11 AR is built to drop into commercial Corbin Russwin mortise cylinder assemblies.
