Corbin Russwin 487K15 57A2 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 487K15 plug, and is it a complete cylinder?
It is the plug only, the rotating core piece that carries the pins and accepts the key, not a complete mortise cylinder. The 487K15 is a 7-pin X Class plug sized for 1-3/8 inch Corbin Russwin mortise cylinder housings and keyed to the 57A2 keyway. If you need a whole cylinder with shell, cam and housing, this is not that part; it is a service item for rebuilding or rekeying a cylinder you already have.
2) Will a 57A2 plug work in my existing Corbin Russwin keying system?
Only if that system is on the 57A2 keyway. The plug is factory keyed to Corbin Russwin 57A2, so it interchanges within a 57A2 masterkey system. Corbin Russwin uses many keyways, and a plug cut for one keyway will not accept keys from another, so pull a key and confirm the keyway stamp before you order.
3) Does the 1-3/8 inch refer to the plug or the cylinder body?
It refers to the mortise cylinder length the plug is built for: 1-3/8 inch housings, which is the common commercial mortise cylinder size. A plug cut for a 1-3/8 inch cylinder will not fill a 1-1/4 or 1-1/2 inch shell correctly, so measure the cylinder you are servicing from the face to the back of the shell before ordering.
4) I need a full mortise cylinder, not a plug. What should I be looking at instead?
You want a complete cylinder assembly. The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder on the Schlage C keyway, and Adams Rite makes the 4036 five-pin mortise cylinder, a Grade 1 unit for openings down to 1/2 inch minimum door thickness typical of aluminum storefront. Neither is Corbin Russwin keyed, so if the building is on a Corbin 57A2 system you need a Corbin cylinder instead.
5) Can I use this plug on a rim cylinder or a key-in-knob lock?
No. The 487K15 is cut for a mortise cylinder shell and nothing else. For rim applications look at 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, the Kaba Ilco 1539 universal knob and lever cylinder covers that format.
6) What should I use instead of the Corbin Russwin 487K15 if the opening takes a rim cylinder rather than a mortise cylinder?
The 487K15 57A2 plug fits 1-3/8 inch mortise cylinder housings, so it will not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal tailpiece cam; both ship with two keys. The BEST 12E Series dummy rim cylinder at 1-5/32 inch diameter covers rim openings that need the look without keyed function.
7) If I want to rekey without disassembling the cylinder, what is the alternative to the Corbin Russwin 487K15 plug?
Servicing the 487K15 57A2 means working the plug itself into a 1-3/8 inch mortise cylinder. An interchangeable-core approach removes that step: the BEST 1CB Peaks 150 Series and the BEST 1CDF drill resistant patented 7-pin brass 150 Series are interchangeable core cylinders, and the BEST 1C Series 5-pin core is a standard core. On the Schlage side, the 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 C keyway with a 643E Aged Bronze finish.
8) What finishes does the 487K15 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Since the plug face is the part you see through the trim ring, pick the one that matches the escutcheon or rose already on the door. Satin chrome is the usual match for brushed stainless and aluminum trim; satin brass matches brass and bronze hardware.
9) Why choose a 7-pin plug over a 6-pin for a commercial building?
The extra pin chamber adds key control and pick resistance, which is why the X Class 7-pin format shows up in offices, schools, healthcare and government work where masterkeying depth and restricted keys matter. Six-pin commercial cylinders, like the Detex MC65 mortise cylinder on the Schlage C keyway, are simpler and fine for standalone openings but give you less room in a large master key system.
10) We want to stop rekeying cylinders on service calls. Is this plug the right long-term approach?
A plug swap still means pulling and disassembling the cylinder in the shop or at the door. If the goal is core swaps at the opening in seconds, an interchangeable core platform is the better standard: BEST 1C 5-pin standard cores, the 1CB 150 Series, or the drill resistant 1CDF 7-pin patented core. Schlage's 20-057 full size interchangeable core is another route. The Corbin 487K15 plug makes sense when the building is already committed to conventional Corbin Russwin mortise cylinders on the 57A2 keyway.
11) Will a Kaba Ilco replacement cylinder work in place of the Corbin Russwin 487K15?
They address different hardware. The 487K15 57A2 is a 7-pin X Class plug for 1-3/8 inch mortise cylinders keyed to the Corbin Russwin 57A2 keyway. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, the 1549 is a key-in-deadbolt cylinder, and the 1579 is a knob and lever cylinder for Sargent - all cataloged with a deadbolt function rather than mortise cylinder plug service.
12) I need a keyed cylinder for a Corbin Russwin lever lock, not a mortise plug - what are my options?
The 487K15 57A2 is a mortise cylinder plug, not a key-in-lever cylinder. For key-in-lever service, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different and supplied with two cut keys.
13) What looks like a substitute for the Corbin Russwin 487K15 but is not?
Cylinder pulls are the common mix-up. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 is a five pin tumbler cylinder pull for the Adams Rite 5017 wood door deadlock. Those are pull assemblies tied to specific Adams Rite deadlocks, while the 487K15 57A2 is the 7-pin X Class plug that goes inside a 1-3/8 inch Corbin Russwin mortise cylinder. The Emtek CY4 cylinder, sold as a single piece, is likewise a different item rather than a Corbin Russwin plug.
14) For a residential deadbolt or handleset, is the Corbin Russwin 487K15 the right cylinder?
No - the 487K15 57A2 plug is a commercial part for Corbin Russwin mortise cylinders. Residential-style retrofits are covered by Medeco: the 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 the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
15) Which cylinder option gives me a stated ANSI grade if my spec requires one?
Of the mortise cylinder options, the Adams Rite 4036 Series is listed as Grade 1 with a 1/2 inch minimum door thickness and five-pin security. The Corbin Russwin 487K15 57A2 is a commercial 7-pin X Class plug used to service existing 1-3/8 inch Corbin Russwin mortise cylinders.
16) Is the 487K15 a genuine Corbin Russwin part or an aftermarket copy?
It is an authentic Corbin Russwin cylinder component, built to the same fit and tolerances as the plug that came out of the cylinder. That matters on a plug: an off-spec plug binds in the shell or sits proud of the cylinder face, and the pin chambers have to line up exactly with the shell for the lock to operate.
17) Is this plug meant for residential deadbolts or commercial openings?
Commercial. It is a service part for Corbin Russwin mortise cylinders in offices, schools, hospitals, municipal buildings, retail, warehouses and multi-tenant residential. For a residential deadbolt or handleset, retrofit cylinders like the Medeco 1075127 5-pin rim type for handlesets and deadbolts are the right category instead.
18) Does the Corbin Russwin 487K15 come in a chrome finish or only brass?
The 487K15 57A2 plug is offered in 606 Satin Brass and 626 Satin Chrome. If a different look is needed on a rim opening instead, the Schlage 20-057-C FSIC core is listed in 643E Aged Bronze.
