Corbin Russwin 487K11 67 626 – Frequently Asked Questions

1) If I need a complete 1-1/8 inch mortise cylinder rather than just the plug, what can I use instead of the Corbin Russwin 487K11 27?
The Corbin Russwin 487K11 27 is a replacement plug component for 1-1/8 inch mortise cylinders, so it does not give you a working cylinder on its own. For a complete 1-1/8 inch mortise cylinder, the Detex MC65 is a 6-pin commercial mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Both are full cylinders that thread into a mortise lock body, while the 487K11 27 replaces only the keyed plug inside an existing Corbin Russwin cylinder.
2) Does the 487K11 plug work in both 5-pin and 6-pin cylinders?
Yes. The 487K11 supports 5-pin and 6-pin configurations, so it covers both the shorter 5-pin keying and the deeper 6-pin systems used for larger master key programs.
3) I manage a building with Corbin Russwin mortise locks. Can I re-key a whole floor with these plugs?
That's the normal use. Swapping the plug lets you change the keying, or move a cylinder to a different X Class keyway, without pulling the mortise lock body or buying complete cylinders. Order all the plugs in the same keyway number so the floor stays on one key system, and keep the pinning consistent at 5 or 6 pins across the group.
4) Do I need a locksmith to install a 487K11 mortise cylinder plug?
Practically, yes. The plug arrives as a keying component, so it has to be pinned to your key and assembled into the cylinder shell, which means pinning kit, follower and a key cut in the matching X Class keyway. A maintenance tech who doesn't pin cylinders is better off ordering a complete keyed mortise cylinder such as the Detex MC65.
5) Is a Schlage 20-021 rim cylinder a substitute for the Corbin Russwin 487K11 27 plug?
No. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, which mounts through the door behind a rim exit device rather than threading into a mortise lock. The Corbin Russwin 487K11 27 is a 5 and 6-pin X Class plug that goes inside a 1-1/8 inch Corbin Russwin mortise cylinder. If your opening uses a rim device, look at the 20-021 or the 20-022 with its horizontal tailpiece cam; if you are rekeying or changing the keyway of a mortise cylinder, the 487K11 27 is the part that changes.
6) We want to stop swapping plugs and move to interchangeable cores instead. What should we look at?
Replacing the Corbin Russwin 487K11 27 plug means disassembling the mortise cylinder each time keying changes. If you would rather pull and swap a core by hand, the BEST 1C Series standard 5-pin cylinder core and the BEST 1CB 150 Series interchangeable core are small format interchangeable cores, and the BEST 1CDF is a drill resistant patented 7-pin interchangeable core in brass. On the full size side, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those change the cylinder architecture of the opening, where the 487K11 27 keeps the existing Corbin Russwin mortise cylinder in service.
7) The door has a key-in-lever or key-in-knob lock, not a mortise lock. Can I use the 487K11 27?
No. The Corbin Russwin 487K11 27 plug is built for the 1-1/8 inch mortise cylinder format used with mortise locksets. For key-in-knob and key-in-lever bodies, the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder and the Kaba Ilco 1599 is a key-in-knob replacement cylinder; the Kaba Ilco 1579 is the knob and lever cylinder for Sargent locks. Falcon offers the A23161-05 G key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with two cut keys.
8) What do I order for a deadbolt instead of the Corbin Russwin 487K11 27?
The Corbin Russwin 487K11 27 is a plug for a mortise cylinder and is not a deadbolt cylinder. For deadbolt openings, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder. Medeco lists the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
9) What finishes does the Corbin Russwin 487K11 plug come in?
Two: 606 satin brass and 626 satin chrome. Match the plug face to the cylinder ring and the rest of the trim on the door, since the plug face is the part visible through the cylinder collar.
10) Is the 487K11 plug rated for commercial traffic or is it a residential part?
Commercial. It's built as an OEM component for commercial mechanical lock systems and is used in offices, schools, healthcare, government buildings, retail and multi-tenant residential.
11) I need a non-keyed filler for an unused cylinder hole, not a working plug. What is the alternative?
The Corbin Russwin 487K11 27 is a keyed X Class plug in 5 and 6-pin configurations, so it is meant to operate. If the opening needs a blank that fills the hole without keying, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy option in the set. Note it is a rim format part, not a mortise plug.
