Corbin Russwin 487K17 27B2 626 – Frequently Asked Questions

1) What is the 27B2 keyway, and can it be keyed into our building's existing Corbin Russwin master key system?
27B2 is a Corbin Russwin keyway designation. The plug is cut for that keyway, so it drops into a key system already built on 27B2 and can be pinned to your existing masterkey scheme. If the rest of your facility runs on a different Corbin Russwin keyway, order the plug in that keyway instead, because the keyway is machined into the plug and cannot be changed.
2) Can I use the 487K17 in a rim cylinder or an interchangeable core housing?
No. It is a mortise cylinder plug in the 1-1/2 inch format and belongs in a mortise cylinder shell. For rim applications, look at rim cylinders such as the Schlage 20-021 (6-pin, vertical tailpiece cam) or 20-022 (horizontal tailpiece cam). For interchangeable core work, a full-size or small-format core such as the BEST 1CDF 7-pin drill resistant core or Schlage 20-057 FSIC core is the right family.
3) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 487K17?
The 487K17 is a 7-pin X Class cylinder plug sized for 1-1/2 inch mortise cylinder applications, so it serves a housing that is already in the door. When the whole cylinder has to be replaced, the Adams Rite 4036 is a complete mortise cylinder with five-pin security in the 4036 Series, rated Grade 1, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in the Schlage C keyway. Choose the 487K17 when you are rebuilding an existing Corbin Russwin cylinder and keeping it on its key system; choose a complete cylinder when the housing itself is being swapped.
4) Is the Corbin Russwin 487K17 plug the same thing as an interchangeable core?
No. The 487K17 is a 7-pin X Class plug that drops into a compatible Corbin Russwin mortise cylinder housing as a component-level replacement part. An interchangeable core is a self-contained keyed unit pulled and replaced with a control key, such as the BEST 1CB in the 1CB Series or the BEST 1CDF drill resistant patented 7-pin brass core in the 150 Series. If your hardware is keyed with full-size or small-format cores, you want a core, not a mortise cylinder plug.
5) My lock uses a rim cylinder, not a mortise cylinder. What do I order instead of the 487K17?
The 487K17 is built for 1-1/2 inch mortise cylinder applications, so it will not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. If the rim device is keyed with full-size interchangeable cores, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
6) Why choose a 7-pin X Class plug over a standard 6-pin cylinder?
The seven-pin X Class configuration is a restricted, higher key-control platform, which is what facilities use when they want to limit unauthorized key duplication across a large keyed system. A 6-pin conventional cylinder, like the Detex MC65 mortise cylinder in Schlage C keyway, is the open-keyway alternative: easier to source and key locally, with no key control. Pick X Class when key control matters; pick a standard keyway when it does not.
7) I need a mortise cylinder for a Corbin Russwin lock but we don't run X Class keying. What should I look at?
You need a complete mortise cylinder rather than an X Class plug. The Detex MC65 is a 1-1/8 inch six-pin commercial mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Note the MC65 is 1-1/8 inch, not the 1-1/2 inch length the 487K17 plug is sized for, so confirm the length your mortise lock body and trim require before ordering.
8) I need to rekey a key-in-lever lockset, not a mortise lock. Is the Corbin Russwin 487K17 the right part?
No. The 487K17 is a mortise cylinder plug in the 27B2 keyway for Corbin Russwin mortise lock assemblies. For key-in-knob and key-in-lever hardware, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway supplied keyed different with two cut keys.
9) What is a simpler five-pin alternative if I do not need the 7-pin X Class configuration?
The 487K17 uses a 7-pin X Class plug configuration for enhanced key control. Where a five-pin system is acceptable, the Adams Rite 4036 is a mortise cylinder with five-pin security, and the BEST 1C5 is a standard 5-pin cylinder core in the Standard and Premium Cores line. Note that the 487K17 keys into Corbin Russwin systems on the 27B2 keyway, so a switch to either of those means moving that opening off the existing Corbin Russwin key system.
10) Will the 487H17 plug work in a deadbolt, or do I need a different cylinder for a deadbolt opening?
The Corbin Russwin 487K17 is a mortise cylinder plug intended for mortise lock assemblies, not for deadbolt cylinders. For deadbolt service, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the Kaba Ilco 1599 is a key-in-knob replacement cylinder, both catalogued for deadbolt function. Medeco offers retrofit options as well, including the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
11) For a narrow stile aluminum door with an Adams Rite deadlock, is a mortise cylinder plug like the 487K17 what I need?
No. The 487K17 is a component plug for Corbin Russwin mortise cylinder housings. Adams Rite deadlock systems take dedicated cylinder pulls: 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 wood door applications with the 5017 wood door deadlock and deadlatch.
12) Can I use the 487K17 to rekey an Emtek handleset?
No. The 487K17 is a Corbin Russwin mortise cylinder plug on the 27B2 keyway for commercial mortise lock assemblies. Emtek hardware takes its own cylinder parts, such as the Emtek CY4 cylinder sold each, and Medeco offers retrofit cylinders for that platform including the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1065244 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
13) We are standardizing a facility on interchangeable cores. How does that change whether the 487K17 fits the plan?
The 487K17 is a component-level replacement plug that keeps an existing Corbin Russwin mortise cylinder on its 27B2 key system, which suits maintenance and rekeying of hardware already in place. A core-based standardization program is served by interchangeable core products instead: the BEST 1CB in the 1CB Series, the BEST 1CDF drill resistant patented 7-pin brass core, and the Schlage 20-057-C full size interchangeable core in the C keyway with a 643E Aged Bronze finish. Many facilities run both, using plugs for legacy mortise cylinders and cores on newly standardized openings.
14) Is this part suitable for commercial buildings, or is it residential hardware?
Commercial. The 487K17 plug is a commercial door hardware component intended for mortise lock service in offices, schools, hospitals, government buildings, retail, multi-tenant residential and industrial facilities, which is the environment X Class key control is normally specified for.
15) Do I order the 487K17 by model number including the keyway?
Yes, the ordering designation carries the keyway: 487K17 27B2. Specify the finish alongside it, either 606 Satin Brass or 626 Satin Chrome. Without the keyway suffix a supplier cannot tell which key system the plug is cut for.
16) I need a non-keyed filler for an opening being standardized. Is the 487K17 available as a dummy?
The Corbin Russwin 487K17 is a keyed 7-pin X Class plug for mortise cylinder service, offered in 606 Satin Brass and 626 Satin Chrome. Where a non-operating filler is what the opening calls for, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter covers that role instead.
