Corbin Russwin 487K13 27A1 606 – Frequently Asked Questions

1) Will the 487K13 plug fit any 1-1/4 inch mortise cylinder, or only Corbin Russwin?
Corbin Russwin only. The plug is machined as a genuine Corbin Russwin cylinder component and drops into qualifying Corbin Russwin mortise cylinder housings in the 1-1/4 inch format. Other brands' mortise cylinders use different plug diameters, tailpiece and cam arrangements, and keyway profiles, so this will not serve as a generic 1-1/4 inch plug. For a non-Corbin opening, buy a complete cylinder to suit that brand, such as the Detex MC65 mortise cylinder in Schlage C keyway.
2) What does 7-Pin X Class mean on a Corbin Russwin cylinder plug?
X Class is Corbin Russwin's high security pin system, and this plug is drilled for 7 pins rather than the more common 6. The extra chamber plus the X Class configuration gives tighter key control and added pick resistance, which is why it shows up on office, institutional, and multi-tenant systems. Practically, it means the plug only accepts X Class 7-pin keying, so your pinning kit, keys, and master key program all have to be on the same system.
3) Do I have to key the 487K13 plug to the 27A1 keyway I already use?
The keyway is fixed at 27A1, so it's only usable inside a Corbin Russwin system running that keyway section. If your building's existing X Class master key program is cut on a different keyway, this plug will not accept those keys and you need the matching keyway version. Confirm the section stamped on your current key or cylinder before ordering, particularly if you are standardizing a facility on one key system.
4) My exit device takes a rim cylinder - will the Corbin Russwin 487K13 work?
No. The 487K13 is a plug for a 1-1/4 inch mortise cylinder housing, which threads into a mortise lock case. Rim cylinders mount through the door behind rim exit devices and drive the device with a tailpiece. For those openings, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the Schlage 20-022 is the same cylinder with a horizontal tailpiece cam, each supplied with two keys. Match the cam orientation to what the device requires.
5) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 487K13?
The 487K13 is a replacement cylinder plug only - the keyed core that drops into an existing 1-1/4 inch Corbin Russwin mortise housing. If the whole cylinder body needs replacing, a complete mortise cylinder is the right part: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder for doors 1/2 inch minimum thickness. Both are full cylinders keyed to their own systems, so they will not carry over a Corbin Russwin 27A1 master key program the way the 487K13 plug does.
6) I want to rekey doors without pulling cylinders apart - is there an alternative to the 487K13 plug?
The 487K13 is a fixed plug: rekeying means removing the cylinder and repinning the plug on the bench. If the goal is swapping key control in seconds at the door, an interchangeable core platform does that instead. The BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in brass, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those are different key systems from the Corbin Russwin 27A1 keyway, so moving to them means converting the openings rather than servicing them.
7) What finishes does the Corbin Russwin 487K13 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Since the plug face is the part you see through the cylinder ring, pick the one that matches the surrounding trim. 626 Satin Chrome is the usual match for brushed chrome and satin stainless lever and escutcheon hardware, 606 for brass trim.
8) I need to swap keying on a lot of doors quickly. Is replacing plugs the right approach?
Not usually, no. Pulling and repinning plugs like the 487K13 is bench work on each cylinder, which is fine for a handful of Corbin Russwin mortise cylinders but slow across a building. If speed of rekeying is the real goal, an interchangeable core system is the better fit, for example BEST 1CB 150 Series interchangeable core cylinders or the BEST 1CDF drill resistant patented 7-pin core, where a control key pulls the core in seconds. Choose the 487K13 when you are maintaining an existing Corbin Russwin X Class system rather than converting away from it.
9) The lock is a key-in-lever, not a mortise lock - what replaces the cylinder there?
A key-in-knob or key-in-lever chassis takes a small cylinder that seats in the knob or lever, not a mortise plug like the 487K13. Kaba Ilco offers the 1539 universal key-in-knob/lever cylinder, the 1579 knob and lever cylinder for Sargent locks, and the 1599 key-in-knob replacement cylinder. 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. Confirm the lock chassis brand before ordering, since these cylinders are chassis-specific.
10) I need a keyed cylinder for an aluminum storefront deadlock - is the 487K13 the right part?
It is not. The 487K13 serves Corbin Russwin mortise lock assemblies in commercial openings. Narrow-stile aluminum storefront deadlocks are typically served by Adams Rite parts: the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the 4025 is a five-pin tumbler cylinder pull using through-screws for the same MS1847. For a wood door deadlock, the Adams Rite 4026 five-pin cylinder pull is built for the 5017 wood door deadlock and deadlatch.
11) How does the 7-pin 487K13 plug compare to 5-pin and 6-pin cylinder options for key control?
The 487K13 uses a 7-pin X Class plug with the 27A1 keyway, a configuration aimed at tighter key control and pick resistance in large master key programs. Among other cylinders, the BEST 1C5 is a standard 5-pin core and the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core, while the Detex MC65 and the Schlage 20-021 rim cylinder are 6-pin. More pin chambers give a master key system more depth to work with; the practical decision is which key system the facility already standardizes on.
12) What cylinder should I use on a residential-style handleset or deadbolt instead of the 487K13?
The 487K13 is a commercial mortise plug and will not serve a handleset or a residential deadbolt. Medeco offers retrofit cylinders built for those: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065140 is a 5-pin retrofit for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. Emtek also lists the CY4 cylinder as a single part.
13) Is a deadbolt cylinder an acceptable substitute for the 487K13 mortise plug?
No - they are different parts despite both being called cylinders. The 487K13 is the plug that carries the pins and keyway inside a 1-1/4 inch Corbin Russwin mortise cylinder. The Kaba Ilco 1549 is a key-in-deadbolt cylinder built for deadbolt function, as are the Ilco 1539 and 1599 cylinders. Those replace the cylinder in a bored deadbolt or knob chassis and do not thread into a mortise lock case.
14) Is this plug suitable for high traffic commercial doors, or is it a residential part?
It's a commercial part. The 487K13 is built to Corbin Russwin's commercial cylinder standards and is used in office buildings, schools, hospitals, retail, government facilities, warehouses, and multi-tenant residential. For a house or light residential deadbolt, a replacement cylinder like the Kaba Ilco 1549 key-in-deadbolt cylinder is the more sensible route than rebuilding an X Class mortise cylinder.
15) I need a non-keyed cylinder to fill an opening - does the 487K13 have a dummy version?
The 487K13 is a keyed 7-pin plug, so it is not the part for a blank or non-operating application. The BEST 12E Series dummy rim cylinder, with a 1-5/32 inch diameter, is built specifically as a non-keyed rim cylinder for filling a prep where no key function is needed.
16) Can I match the 487K13 plug finish if I switch to a different brand cylinder?
The 487K13 plug comes in 606 Satin Brass and 626 Satin Chrome to coordinate with Corbin Russwin trim. Cross-brand cylinders are catalogued in their own finish ranges - the Schlage 20-057-C full size interchangeable core, for example, is a C keyway core supplied in 643E Aged Bronze. If visible finish continuity across a fleet of doors matters, staying with the Corbin Russwin plug in 606 or 626 keeps the exposed face consistent with the existing hardware.
