Corbin Russwin 487K15 57B1 626 – Frequently Asked Questions

1) Does the 487K15 have to match my existing keyway?
Yes, and the 487K15 is cut for the Corbin Russwin 57B1 keyway. A plug in a different keyway won't accept your existing keys, so the 57B1 version only drops into a 57B1 system. It also has to be a 7-pin X Class system, not a 6-pin conventional one.
2) If I need a complete mortise cylinder rather than just the plug, what should I order instead of the Corbin Russwin 487K15?
The Corbin Russwin 487K15 is a replacement plug, an internal component of a mortise cylinder assembly, not a whole cylinder. If the housing also needs replacing, order a complete mortise cylinder such as the Adams Rite 4036 mortise cylinder with five-pin security, listed as Grade 1 in the 4036 Series, or the Detex MC65 mortise cylinder with Schlage C keyway in 1-1/8 inch, 6-pin.
3) Can I use a BEST interchangeable core in place of the Corbin Russwin 487K15 plug?
No. The 487K15 is a 7-pin X Class plug built for 1-3/8 inch Corbin Russwin mortise cylinder housings with the 57B1 keyway, so it drops into the existing Corbin Russwin cylinder body. A BEST interchangeable core, such as the 1CB 150 Series core or the 1CDF drill resistant patented 7-pin brass 150 Series core, is a removable core that requires BEST interchangeable core housings and its own control key, so it is a different keying system rather than a plug swap.
4) My cylinder is in a knob or lever, not a mortise lock. Is the Corbin Russwin 487K15 still the right part?
No. The 487K15 is dimensioned for 1-3/8 inch mortise cylinder housings. For key-in-knob and key-in-lever bodies, use a cylinder built for that format, such as the Kaba Ilco 1539 Series key-in-knob/lever universal cylinder, the Kaba Ilco 1599 key-in-knob replacement cylinder, the Kaba Ilco 1579 knob and lever cylinder for Sargent, or the Falcon A23161-05 G key-in-lever cylinder with 6-pin G keyway supplied keyed different with 2 cut keys.
5) Will the 487K15 plug fit a rim cylinder?
No. It's a mortise cylinder plug, sized to 1-3/8 inch mortise housings. Rim cylinders are a separate body with a tailpiece, such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam. Rebuilding a rim cylinder calls for rim parts, not this plug.
6) I need a full replacement mortise cylinder, not a plug. What should I look at instead?
A complete cylinder is a different item. The Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in the Schlage C keyway. Neither uses the Corbin Russwin 57B1 keyway, so if your building is keyed to 57B1 you want a Corbin Russwin cylinder rather than either of those.
7) Can I swap this Corbin Russwin plug into an interchangeable core system?
No. The 487K15 is a plug for a conventional 1-3/8 inch Corbin Russwin mortise cylinder, not a core. Interchangeable core systems use a removable figure-eight core instead, like the BEST 1C 5-pin core, the BEST 1CDF drill-resistant 7-pin core, or the Schlage 20-057 full-size interchangeable core. Those are not cross-compatible with a conventional plug.
8) How do I identify the right part number when ordering this Corbin Russwin plug?
Order by model 487K15 57B1, then pick the finish. The 487K15 designates the 7-pin X Class 1-3/8 inch mortise plug and 57B1 is the keyway; both parts of that designation matter, because the same plug body in a different keyway won't run your keys.
9) Is a rim cylinder an acceptable substitute for the Corbin Russwin 487K15?
No. The 487K15 serves a mortise cylinder assembly, which threads into the lock case. Rim cylinders mount through the door and drive a tailpiece: examples are the Schlage 20-021 6-pin rim cylinder with vertical tailpiece cam and the Schlage 20-022 6-pin rim cylinder with horizontal tailpiece cam. Those are for rim exit devices, not mortise lock bodies.
10) I want a keying system where cores can be swapped without disassembling the cylinder. What is the alternative to the 487K15 approach?
Replacing a 487K15 plug means servicing the mortise cylinder itself, since the plug is an internal component of that assembly. For facilities that want field-swappable keying, full size interchangeable core products are the alternative: the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam and the Schlage 20-057-C full size interchangeable core in C keyway, 643E Aged Bronze, both use an FSIC core that pulls with a control key.
11) What is the difference between ordering a 5-pin cylinder and the 7-pin Corbin Russwin 487K15 plug?
The 487K15 uses a 7-pin X Class configuration with the proprietary 57B1 keyway, which supports restricted key control within Corbin Russwin keying systems. Five-pin alternatives in the same family of parts include the BEST 1C Series standard 5-pin cylinder core and the Adams Rite 4036 mortise cylinder with five-pin security, Grade 1. Pin count and keyway must match the master key system already in the building, so this is a keying decision, not a like-for-like swap.
12) Does the Corbin Russwin 487K15 work in a residential deadbolt or handleset?
The 487K15 is designated commercial and is a component of Corbin Russwin mortise cylinder assemblies. Deadbolt and handleset retrofits call for cylinders built to those tailpiece patterns, such as the Medeco 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks 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.
13) My storefront uses an Adams Rite MS deadlock with a cylinder pull. Would the 487K15 fit that?
No. The 487K15 plug is made for 1-3/8 inch Corbin Russwin mortise cylinder housings. Adams Rite MS-type storefront hardware uses dedicated cylinder pulls: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for the MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch.
14) What finishes does the Corbin Russwin 487K15 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder ring and the rest of the trim on the door, since the plug face is the part you see.
15) Is this plug suitable for a commercial building or is it residential hardware?
Commercial. The 487K15 is a Corbin Russwin cylinder part built for mechanical lock service in offices, schools, healthcare, government buildings, retail, warehouses, and multi-tenant residential. It's the kind of part a locksmith or in-house maintenance shop keeps for rekeying work on a keyed system.
16) I need a non-keyed filler for an opening. Is the 487K15 usable for that?
No. The 487K15 is a functioning 7-pin keyed plug for Corbin Russwin mortise cylinders. If the opening needs a dummy cylinder that fills the prep without operating, the BEST 12E Series dummy rim cylinder with 1-5/32 inch diameter is built for that purpose.
17) Will the Satin Brass 487K15 match hardware finished in chrome?
The 487K15 plug is offered in 606 Satin Brass and 626 Satin Chrome, so a chrome opening can be matched by ordering the 626 finish rather than substituting another brand. Among comparable cylinder products, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze, a darker tone that would not blend with satin chrome trim.
