Corbin Russwin 487K11 57D1 626 – Frequently Asked Questions

1) Will the 487K11 plug work in a 5-pin cylinder, or only 6-pin?
Both. The 487K11 plug is drilled to accept 5-pin and 6-pin configurations, so the same plug covers either keying depth in a Corbin Russwin 1-1/8 inch mortise cylinder. That is useful if a building mixes 5-pin and 6-pin cylinders across a master key system.
2) What keyways can I order this Corbin Russwin mortise plug in?
Two keyway choices: D1 and D2, both within the Corbin Russwin 57D keyway family. Pick the one that matches the section your existing key system is cut to, since a plug in the wrong section will not accept your keys.
3) Does the 487K11 plug fit rim cylinders or knob cylinders too?
No. It is machined to 1-1/8 inch mortise cylinder dimensions only. For rim applications you would want a rim cylinder such as the Schlage 20-021 with vertical tailpiece cam or the 20-022 with horizontal cam; for key-in-knob or lever replacement, something like the Kaba Ilco 1599 key-in-knob cylinder.
4) I need a complete 1-1/8 inch mortise cylinder, not just the plug. What should I order instead of the Corbin Russwin 487K11?
The 487K11 57D1 is an individual X Class cylinder plug machined for 1-1/8" mortise cylinder housings - it is the keyed core piece, not a full cylinder assembly. If the housing is not already in hand, the Detex MC65 is a complete 1-1/8" 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 for doors from 1/2" minimum thickness. Both are whole cylinders that thread into a mortise lock body; the 487K11 assumes you are rebuilding an existing Corbin Russwin cylinder and keeping its shell.
5) Is the Corbin Russwin 487K11 plug the same idea as a BEST interchangeable core?
They solve re-keying differently. The 487K11 57D1 is a plug that is pinned and installed inside a 1-1/8" mortise cylinder body, supporting 5-pin and 6-pin builds in the 57D keyway. A BEST 1C Series standard 5-pin core or the 1CB 150 Series interchangeable core is removed and swapped with a control key, with no disassembly of the cylinder. If your doors already carry Corbin Russwin mortise cylinders, the 487K11 keeps that hardware in place; moving to a BEST core means the housing has to accept a figure-eight core.
6) My opening uses a rim exit device, not a mortise lock. Can I use the 487K11 there?
No. The 487K11 57D1 is cut to 1-1/8" mortise cylinder dimensions. Rim exit devices take a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, and the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation the device calls for.
7) What finishes does the 487K11 plug come in, and does it need to match the cylinder?
Satin brass (606) and satin chrome (626). The plug face is the visible part once the cylinder is installed, so order the finish that matches the cylinder housing and the rest of the trim on the opening.
8) Can a property manager use this to re-key doors without buying new cylinders?
That is the intent. Swapping the plug lets a locksmith bring an existing Corbin Russwin 1-1/8 inch mortise cylinder into a different keyway or keying scheme while keeping the housing and the lock in the door. It is a commercial-grade part aimed at re-keying and maintenance programs, not a DIY item, since pinning the plug to a master key schedule takes a keying kit and the system's bitting.
9) What is an X Class plug and why does it matter for key control?
X Class is Corbin Russwin's controlled keying designation. The 487K11 is an individual X Class plug, meaning it is built for restricted, professionally administered key systems where blanks and duplication are controlled rather than open to any hardware store. For facilities running healthcare, education, or government key control programs, that restriction is the point of choosing this plug over a generic one.
10) If I want interchangeable cores instead of re-plugging cylinders, what should I look at?
Re-plugging a mortise cylinder means pulling the cylinder and pinning a new plug. An interchangeable core system lets you pull and swap the core with a control key instead, which is faster across a large building. ZenSupply carries BEST small format cores such as the 1C Series standard 5-pin core and the drill-resistant 1CDF 7-pin patented core, plus Schlage full size interchangeable core options like the 20-057 FSIC rim cylinder. Those are a system change, not a drop-in for an existing Corbin Russwin mortise cylinder.
11) What do I use for a key-in-knob or key-in-lever cylinder instead of the 487K11?
The 487K11 57D1 only serves mortise cylinder housings. For knob and lever cylinders, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. On Falcon RU/T levers, the A23161-05 G is a 6-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys.
12) I need a deadbolt cylinder rather than a mortise plug - what is the closest alternative?
Go to a purpose-built deadbolt cylinder rather than the 487K11 plug. The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and Medeco offers 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 Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
13) For a narrow stile aluminum storefront with an Adams Rite deadlock, does the Corbin Russwin 487K11 apply?
Not directly - the 487K11 57D1 is a replacement plug for Corbin Russwin mortise cylinder assemblies. For Adams Rite MS1847 deadlock and deadlatch openings, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws. On wood doors with the Adams Rite 5017 deadlock/deadlatch, the 4026 five pin tumbler cylinder pull is the matching part.
14) I want higher key control than a standard plug. What are the options next to the 487K11?
The 487K11 57D1 is an X Class plug built for controlled, professional keying programs in the 57D keyway. If the program calls for patented key control at the core, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, in the 150 Series. The trade-off is format: the 487K11 stays inside your existing Corbin Russwin mortise cylinders, while the 1CDF requires housings that take a BEST interchangeable core.
15) What is the difference between the Schlage 20-057 and 20-057-C when I am comparing FSIC options to the 487K11?
Both Schlage parts are full size interchangeable core products: the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E Aged Bronze finish. Either replaces the whole keyed unit. The Corbin Russwin 487K11 57D1 instead rebuilds the inside of an existing 1-1/8" mortise cylinder and comes in 606 Satin Brass and 626 Satin Chrome with D1 and D2 keyway options.
16) Can I use a dummy cylinder in place of the 487K11 where no key function is needed?
If the opening needs the look of a cylinder without keyed operation, a dummy is the right part, not the 487K11 - that plug is pinned for live 5-pin or 6-pin keying in the 57D keyway. The BEST 12E Series dummy rim cylinder measures 1-5/32" in diameter and is a rim format part, so confirm the prep is rim and not a mortise threaded hole before ordering.
