Corbin Russwin 487K19 67A2 626 – Frequently Asked Questions

1) Will a 487K19 plug fit my 1-1/8 inch mortise cylinder?
No. The 487K19 plug is dimensioned for 1-3/4 inch mortise cylinder housings. A 1-1/8 inch housing is a different length and the plug will not seat correctly. For a 1-1/8 inch application, look at a complete cylinder in that length, such as the Detex MC65 mortise cylinder, which is a 1-1/8 inch 6-pin unit.
2) Do my existing keys work with the 487K19, or do I need new ones cut?
The plug is built to the 67A2 keyway, so keys must be cut on 67A2 blanks and bitted to your keying schedule. If the cylinder you're servicing is already on 67A2 within a Corbin Russwin master key system, your existing keys will operate it once the plug is pinned to those combinations. If your building runs a different keyway, this plug won't accept those keys.
3) I need a complete mortise cylinder, not just the plug - what should I order?
The Corbin Russwin 487K19 is a replacement plug only, a service part for re-keying or restoring an existing 1-3/4 inch Corbin Russwin mortise cylinder. If the whole cylinder is being replaced, a complete mortise cylinder such as the Adams Rite 4036 five-pin mortise cylinder, listed as Grade 1 in the 4036 Series, or the Detex MC65 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway is the item to specify. Note that those use their own keyways, so they will not key into an existing Corbin Russwin 67A2 system the way the 487K19 plug does.
4) Can I use a BEST interchangeable core instead of the Corbin Russwin 487K19 plug?
No - they solve different problems. The 487K19 is a replacement plug for a 1-3/4 inch Corbin Russwin mortise cylinder, a 7-pin X Class part with the 67A2 keyway that drops into the existing cylinder housing so the housing and its cam stay in the door. A BEST 1CB 150 Series interchangeable core or the 1CDF drill resistant 7-pin brass 150 Series core is a removable core that requires a BEST-prepped interchangeable core housing; it will not seat in a standard Corbin Russwin mortise cylinder shell. If the openings are already Corbin Russwin conventional mortise cylinders, the 487K19 plug keeps that platform intact; moving to BEST cores is a housing change, not a plug swap.
5) For an aluminum storefront door, is the 487K19 the right cylinder part?
Only if the opening already carries a 1-3/4 inch Corbin Russwin mortise cylinder, since the 487K19 is the replacement plug for that housing. Narrow stile aluminum storefront work more commonly calls for Adams Rite hardware: the 4036 mortise cylinder in the 4036 Series is Grade 1 with a 1/2 inch minimum door thickness, and where a pull-mounted cylinder is needed the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both designed for use with the Adams Rite MS1847 deadlock/deadlatch. For a wood door version of the same idea, the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock/deadlatch.
6) Why choose a 7-pin X Class plug over a standard 6-pin cylinder?
The 7-pin X Class setup adds a seventh tumbler position and puts the keyway under X Class restriction, which limits who can get blanks cut and cuts down on unauthorized key duplication. That matters on schools, hospitals, and government buildings where key control is part of the security plan. If key control isn't the driver, a standard commercial cylinder like the Schlage 20-021 6-pin rim cylinder or a BEST 1C5 standard 5-pin core is the simpler route, though those are different cylinder formats, not mortise plug replacements.
7) I need to re-key a whole facility on interchangeable cores instead of pinning plugs. What should I be looking at?
A replacement plug like the 487K19 is pinned on the bench and reinstalled in the housing, which is fine for one-off service but slow across a campus. If you want to swap cores by hand with a control key, go to an interchangeable core platform instead: BEST offers the 1CB Peaks 150 Series interchangeable core, the 1CDF drill-resistant patented 7-pin brass core, and the 1C 5-pin standard core. Schlage's equivalent is the 20-057 full size interchangeable core. Those are separate keying systems, so standardizing means changing the housings too.
8) Does the 487K19 plug come with keys?
The 487K19 is the plug itself, a replacement part for a mortise cylinder. Plan on supplying keys cut on 67A2 blanks to your own keying schedule. If you want a cylinder that ships with keys already, complete cylinders such as the Schlage 20-022 rim cylinder or the Falcon A23161-05 G key-in-lever cylinder are listed with two cut keys.
9) Can the 487K19 be used on a residential deadbolt or handleset?
It is not intended for that. The Corbin Russwin 487K19 is a commercial mortise cylinder plug for commercial mortise lock systems. Residential deadbolts and handlesets take retrofit cylinders built for those chassis - for example the Medeco 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, the Medeco 1065244 5-pin rim lazy motion cylinder with Emtek tailpiece, or the Medeco 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
10) What is the difference between the 487K19 mortise plug and a rim cylinder like the Schlage 20-021?
Format and where it mounts. The Corbin Russwin 487K19 is a mortise plug: a threaded mortise cylinder body screws into the lock case, and the 487K19 is the 1-3/4 inch plug that sits inside it. The Schlage 20-021 and 20-022 are rim cylinders, mounted through the door from the inside face and driven by a tailpiece - the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, each supplied with 2 keys. Rim cylinders serve rim exit devices and similar surface-applied locks; they are not interchangeable with a mortise cylinder plug.
11) If I want key control on a restricted keyway but not Corbin Russwin, what are the alternatives?
The Corbin Russwin 487K19 gets its key control from the 7-pin X Class configuration with the 67A2 keyway, which restricts unauthorized duplication while staying inside the Corbin Russwin keying system. On other platforms, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series, and it delivers its restriction through a patented core rather than a conventional plug. The choice usually follows the existing hardware: the 487K19 keeps conventional Corbin Russwin mortise cylinders in service, while the 1CDF assumes interchangeable core housings.
12) Will the 487K19 work in a key-in-lever or key-in-knob lock?
No. The Corbin Russwin 487K19 is a mortise cylinder plug in the 1-3/4 inch format, intended for mortise cylinder housings in commercial mortise lock systems. Key-in-knob and key-in-lever locks take a different cylinder entirely - for example the Kaba Ilco 1539 Series key-in-knob / lever universal cylinder, the Kaba Ilco 1599 key-in-knob replacement cylinder, or the Falcon A23161-05 G key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with 2 cut keys. Match the cylinder format to the lock chassis before ordering.
13) I need a non-keyed cylinder for a pull side that does not lock - can I use the 487K19?
No. The Corbin Russwin 487K19 is a keyed 7-pin X Class plug on the 67A2 keyway. For a position that only needs the appearance of a cylinder with no keying, a dummy part is the correct item - for example the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter, in the 12E Series. That is a rim format part, so confirm the prep on the door before ordering.
14) We are standardizing a facility on interchangeable cores - how does that change what I order versus the 487K19?
The Corbin Russwin 487K19 is a conventional mortise plug, so re-keying is done by pulling and re-pinning the plug in the 67A2 keyway. Standardizing on interchangeable cores changes the housing as well as the cylinder: the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with 2 keys, the 20-057-C is the matching full size interchangeable core in the C keyway, and on the BEST platform the 1CB 150 Series and 1CDF 150 Series are the core options. Those let a facility swap cores with a control key instead of servicing plugs, but they require FSIC or BEST prepped housings on every opening being converted.
15) What finishes does the Corbin Russwin 487K19 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder collar and the lock trim already on the opening, since the plug face is the visible part around the keyway.
16) Is the 487K19 an OEM Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. It's an OEM cylinder component made to the original tolerances, which is what keeps it interchangeable with the mortise cylinder housings already installed and keeps the keying consistent with the rest of a Corbin Russwin system.
17) Is there a simpler, lower pin count cylinder part if I do not need 7-pin security?
Yes, depending on the housing. The Corbin Russwin 487K19 is a 7-pin X Class plug with the 67A2 keyway. Where a conventional 5-pin part suits the opening, the BEST 1C Series standard 5-pin cylinder core covers interchangeable core housings, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1. Keep in mind the 487K19 is the only one of these that keeps the opening on the existing Corbin Russwin 67A2 keying system.
18) What finishes does the 487K19 come in compared to other cylinder options?
The Corbin Russwin 487K19 plug is offered in 606 Satin Brass and 626 Satin Chrome, the two finishes that coordinate with most commercial mortise trim. Among the alternatives, the Schlage 20-057-C full size interchangeable core cylinder with the C keyway is listed in 643E Aged Bronze, a darker finish that will not match satin trim. If the goal is a visual match to existing Corbin Russwin mortise hardware, pick the 487K19 finish that matches the escutcheon or rose already on the door.
