Corbin Russwin 487K17 57B1 626 – Frequently Asked Questions

1) Will the 487K17 plug work in my existing Corbin Russwin keying system?
It is cut for the 57B1 keyway, so it keys into a Corbin Russwin system already running 57B1 and nothing else. The 57B1 is a proprietary restricted keyway, which is the point of it: key duplication stays controlled. If the rest of your building is on a different Corbin Russwin keyway section, this plug will not accept those keys.
2) Can I use the 487K17 in a rim cylinder or a key-in-knob lock?
No. It is dimensioned for 1-1/2 inch mortise cylinder housings, so it goes in a mortise cylinder body and nowhere else. For a rim device you 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, a knob cylinder like the Kaba Ilco 1599 replacement or the 1579 for Sargent 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 Corbin Russwin 487K17 is a 7-pin X Class plug for 1-1/2 inch mortise cylinders, sold as a replacement part rather than a full cylinder. When the whole cylinder has to come out of the lock, a complete mortise cylinder is the right item: 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 five-pin mortise cylinder in the 4036 series rated Grade 1. Both are assembled cylinders with their own keyway, so they would not carry an existing Corbin Russwin 57B1 key system the way the 487K17 plug does.
4) Can a Schlage 20-057 interchangeable core be used in place of the Corbin Russwin 487K17 plug?
No. The Corbin Russwin 487K17 is a 7-pin X Class plug with the 57B1 keyway that goes inside a 1-1/2 inch Corbin Russwin mortise cylinder housing. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the Schlage C keyway. FSIC cores drop into housings prepped for interchangeable cores and are keyed to Schlage keyways, so they are a different system rather than a plug swap in a Corbin Russwin mortise cylinder.
5) The 487K17 is for a mortise lock — what do I use if the opening has a rim exit device or a rim deadbolt instead?
The Corbin Russwin 487K17 fits 1-1/2 inch mortise cylinder housings, so it is not the part for rim prep. Rim applications call for a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, each supplied with 2 keys. Cam orientation is what matches the cylinder to the device, so confirm which the device requires before ordering.
6) Is the Corbin Russwin 487K17 the right part for a key-in-lever or key-in-knob lockset?
No. The Corbin Russwin 487K17 is a mortise cylinder plug, dimensioned at 1-1/2 inch for mortise cylinder housings. Key-in-knob and key-in-lever locks take a different cylinder body: the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent locks, the 1599 is a key-in-knob replacement cylinder, 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 2 cut keys.
7) What finishes does the Corbin Russwin 487K17 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder collar and lock trim already on the door, since the plug face is what shows at the keyhole. Satin chrome pairs with 626 satin chrome lock trim, satin brass with 606 brass hardware.
8) Why choose a 7-pin plug instead of a 6-pin for a commercial masterkey system?
The extra pin chamber gives a deeper masterkeying tree and more key change combinations, which is what you want when one system has to cover a lot of doors with multiple levels of master. The 487K17 is 7-pin X Class. If you are working a smaller system, 5- and 6-pin cylinders such as the BEST 1C 5-pin core or a 6-pin cylinder like the Falcon A23161-05 G in the G keyway cover it with fewer pinning steps.
9) If I want interchangeable cores instead of re-pinning plugs, what should I look at?
A plug like the 487K17 means pulling the cylinder and repinning at the bench. Interchangeable core systems let you swap the core with a control key and no disassembly. Options in that direction include the BEST 1CB 150 Series interchangeable core, the BEST 1CDF drill-resistant patented 7-pin core, or Schlage full-size interchangeable core cylinders such as the 20-057 with convertible tailpiece cam. Note those are different keyways and different cylinder formats, so it is a system change, not a drop-in.
10) I want to standardize on interchangeable cores instead of rekeying plugs like the 487K17 — what are my options?
The Corbin Russwin 487K17 is a fixed 7-pin X Class plug that is rekeyed at the cylinder, which suits facilities already running a Corbin Russwin 57B1 system. If the goal is to pull and swap cores in the field instead, BEST interchangeable core cylinders cover that approach: the 1C series standard 5-pin core, the Peaks 1CB in the 150 series, and the 1CDF, a drill resistant patented 7-pin brass interchangeable core in the 150 series. Interchangeable cores require housings prepped for them, so this is a keying-system decision rather than a one-part substitution.
11) What cylinder should I use on an aluminum storefront narrow stile door rather than the Corbin Russwin 487K17?
The Corbin Russwin 487K17 is a 7-pin X Class mortise cylinder plug for Corbin Russwin mortise lock assemblies in commercial openings. Narrow stile aluminum doors running Adams Rite hardware are served by cylinder pulls matched to the deadlock: the Adams Rite 4024 mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws, both for the MS1847 deadlock/deadlatch, while the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock/deadlatch.
12) If a door needs to look keyed but not actually lock, is the 487K17 plug what I want?
No. The Corbin Russwin 487K17 is a functional 7-pin X Class plug with the 57B1 keyway, intended for key control in working mortise cylinders. For an opening that only needs the appearance of a cylinder, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the item built for that purpose.
13) Can I use the Corbin Russwin 487K17 in a residential deadbolt or handleset?
The 487K17 is a commercial 7-pin X Class plug for 1-1/2 inch Corbin Russwin mortise cylinders. Residential deadbolts and handlesets use rim-type lazy motion cylinders instead: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
14) Is this plug suitable for high-traffic commercial buildings, or is it residential-grade?
Commercial. The 487K17 is specified as a commercial mechanical lock component and is used in offices, schools, healthcare facilities, retail, industrial and warehouse buildings, multi-tenant residential and government properties. For a property manager standardizing mortise locks across a portfolio, the value is being able to re-key in place rather than pull whole locks.
15) Is the Kaba Ilco 1549 an alternative to the Corbin Russwin 487K17 for a deadbolt cylinder?
They serve different openings. The Corbin Russwin 487K17 is a mortise cylinder plug in the 7-pin X Class with the 57B1 keyway, offered in 606 Satin Brass and 626 Satin Chrome. The Kaba Ilco 1549 is a key-in-deadbolt cylinder in the 1549 series with a deadbolt function, so it addresses deadbolt bodies rather than mortise cylinder housings. Choose by what the door is prepped for.
