Corbin Russwin 487K17 27A2 626 – Frequently Asked Questions

1) Is the Corbin Russwin 487K17 a complete mortise cylinder or just the plug?
It's the plug only, not a complete cylinder. The 487K17 is a 7-Pin X Class replacement plug for 1-1/2 inch mortise cylinder applications, sold as a replacement part. If you need a whole mortise cylinder rather than the rotating plug assembly, look at a complete unit such as the Adams Rite 4036 mortise cylinder or the Detex MC65 mortise cylinder.
2) What keyway does the Corbin Russwin 487K17 plug use, and will it work in my existing key system?
The plug is cut for the Corbin Russwin 27A2 keyway, a proprietary restricted keyway used for controlled key distribution. It will only accept keys blanked for 27A2, so your existing system has to already be on that keyway. If your building is keyed on a different section, this plug won't take your keys.
3) Can I use this plug to rekey an interchangeable core system?
No. The 487K17 is a mortise cylinder plug, not an interchangeable core, so it is swapped by a locksmith servicing the cylinder rather than pulled with a control key. If you want a core you can change out in seconds across a facility, you need an IC system such as the BEST 1CB 150 Series interchangeable core or the Schlage 20-057 full-size interchangeable core.
4) If the whole mortise cylinder needs replacing rather than just the plug, what is a complete mortise cylinder option?
The Corbin Russwin 487K17 is a replacement plug for 1-1/2" mortise cylinder applications, so it goes into an existing Corbin Russwin housing. If the housing itself is damaged, a complete mortise cylinder is the right call instead: the Detex MC65 is a 1-1/8" 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1. Both are full cylinders, not plugs, and neither carries the 27A2 keyway, so they key to their own systems.
5) Is a BEST interchangeable core the same thing as a 487K17 plug?
No. The Corbin Russwin 487K17 is a 7-Pin X Class plug that drops into a 1-1/2" mortise cylinder housing in the 27A2 keyway. BEST interchangeable cores are removable figure-eight cores for BEST housings: the 1C Series is a standard 5-pin core, the 1CB is a Peaks 150 Series interchangeable core, and the 1CDF is a drill-resistant patented 7-pin brass 150 Series core. A core and a plug are not interchangeable parts, even where the pin count matches.
6) What should I use for an exit device rather than a mortise prep?
The Corbin Russwin 487K17 is dimensioned for 1-1/2" mortise cylinder housings, which is the wrong format for a rim-prepped exit device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal cam; the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Choose the cam orientation your device calls for.
7) I need a cylinder for an aluminum storefront narrow stile door - does the 487K17 work?
The 487K17 is a plug for Corbin Russwin 1-1/2" mortise cylinder housings, so on a narrow stile storefront you would be looking at cylinder pulls and deadlock cylinders instead. The Adams Rite 4024 cylinder pull 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 cylinder pull for the 5017 wood door deadlock/deadlatch. The Adams Rite 4036 mortise cylinder with five-pin security lists a 1/2" minimum door thickness.
8) I need a cylinder for an exit device rim application, not a mortise lock. Is this the right part?
No. This plug is for a 1-1/2 inch mortise cylinder body threaded into a mortise lock case. Rim exit devices take a rim cylinder with a tailpiece, such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam, both 6-pin.
9) What if the lock is a key-in-lever or key-in-knob instead of a mortise lock?
A key-in-lever or key-in-knob lock takes a different cylinder body than the Corbin Russwin 487K17, which is built for 1-1/2" mortise cylinders. For key-in-lever, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with two cut keys. For knob and lever retrofits, Kaba Ilco offers the 1539 Series universal key-in-knob/lever cylinder, the 1579 Series knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder.
10) For a deadbolt cylinder, what is the equivalent part?
The Corbin Russwin 487K17 plug serves mortise lock hardware, not deadbolts. For deadbolt applications, Kaba Ilco lists the 1549 Series key-in-deadbolt cylinder with a deadbolt function, and Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts along with the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
11) Can I use a dummy cylinder instead of the 487K17 where no key function is needed?
No - they do different jobs. The Corbin Russwin 487K17 is a keyed 7-Pin X Class plug in the 27A2 keyway, giving controlled key distribution. The BEST 12E Series dummy rim cylinder with a 1-5/32" diameter is a non-operating filler for openings where a cylinder appearance is wanted without key function, and it is a rim format rather than a mortise plug.
12) What is the retrofit cylinder for an Emtek or Arrow interconnected lock?
Those use dedicated retrofit cylinders rather than a mortise plug like the Corbin Russwin 487K17. Medeco lists the 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the 1065244 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece. Emtek also lists the CY4 cylinder as a parts item.
13) Is this a genuine Corbin Russwin part suitable for commercial doors?
Yes, it's an OEM Corbin Russwin cylinder component rated for commercial use, intended for drop-in service of compatible Corbin Russwin mortise lock hardware in offices, schools, healthcare, retail, government and multi-tenant buildings.
14) What are the finish choices on the 487K17 compared with a Schlage FSIC core?
The Corbin Russwin 487K17 plug comes in 606 Satin Brass and 626 Satin Chrome. The Schlage 20-057-C full size interchangeable core in the C keyway is listed in 643E Aged Bronze. If you are matching existing bright or satin trim, that difference in finish family matters as much as the keyway does.
