Corbin Russwin 487K15 57B2 626 – Frequently Asked Questions

1) Is the Corbin Russwin 487K15 a complete mortise cylinder or just the plug?
It is the plug only. The 487K15 is a 7-Pin X Class cylinder plug sized for 1-3/8 inch mortise applications, sold as a genuine Corbin Russwin replacement component for rebuilding or rekeying an existing mortise cylinder. If you need a complete mortise cylinder assembly rather than the internal plug, order a full cylinder instead, such as the Adams Rite 4036 mortise cylinder or the Detex MC65 mortise cylinder in Schlage C keyway.
2) What keyway does the Corbin Russwin 487K15 plug use, and will it work in my existing master key system?
The plug is cut for the Corbin Russwin 57B2 keyway. It will operate within a Corbin Russwin system built on 57B2 keys. If your building is keyed on a different Corbin Russwin keyway, or on a Schlage or BEST section, this plug will not accept those keys, so match the keyway stamped on your existing cylinders before ordering.
3) Can I use the 487K15 plug to rekey a mortise lock without replacing the whole lock body?
Yes, that is what it is for. Swapping the plug inside the mortise cylinder lets a locksmith change keying without pulling the mortise lock body out of the door. It is a genuine Corbin Russwin cylinder part sized at 1-3/8 inches for standard mortise lock bodies, so the lock, trim, and door prep all stay as they are.
4) What should I use if the opening takes a rim cylinder instead of a mortise cylinder?
The Corbin Russwin 487K15 is built for 1-3/8" mortise lock bodies, 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 two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
5) If I want an interchangeable core system rather than a pinned plug, what are the alternatives?
The 487K15 is a 7-pin X Class plug keyed into a Corbin Russwin 57B2 keyway, so rekeying means working the plug. For a system where the core is swapped instead, the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass 150 Series core, the BEST 1CB is a Peaks 150 Series interchangeable core, and the BEST 1C5 is a standard 5-pin cylinder core. On the Schlage side, the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and the 20-057-C is a full size interchangeable core in the C keyway, 643E Aged Bronze.
6) My building is keyed to a Schlage C system, not Corbin Russwin. What do I use?
The Corbin Russwin 487K15 is configured with the Corbin Russwin 57B2 keyway for keying into established Corbin Russwin master key systems, so it will not accept Schlage C keys. For a C keyway building, the Detex MC65 is a mortise cylinder in the Schlage C keyway, 1-1/8" and 6-pin, and the Schlage 20-057-C is a full size interchangeable core in the C keyway, 643E Aged Bronze.
7) Why choose a 7-pin plug over a 6-pin for a commercial building?
Seven pins give more possible key combinations, which matters when you are maintaining key control across a large master keyed facility. The 487K15 is a 7-pin X Class plug built for that kind of commercial keying platform. By contrast, a lot of commercial cylinders run 6 pins, like the Schlage 20-021 rim cylinder or the Detex MC65 mortise cylinder. If your Corbin Russwin system is already 7-pin X Class, stay with 7-pin so the existing keys and masters continue to work.
8) Is this plug suitable for an interchangeable core system?
No. The 487K15 is a conventional mortise cylinder plug, not a core. If your facility runs small format or full size interchangeable cores so staff can swap keying without a locksmith, look at the BEST 1C Series 5-pin core, the BEST 1CDF drill resistant 7-pin core, or the Schlage 20-057 full size interchangeable core rim cylinder instead.
9) Can the Corbin Russwin 487K15 plug be used in a key-in-lever or key-in-knob lockset?
No. The 487K15 is a mortise cylinder plug sized at 1-3/8" for mortise lock bodies. Key-in-lever and key-in-knob bodies take their own cylinder format: the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T Series with a 6-pin G keyway, keyed different with two cut keys; the Kaba Ilco 1539 Series is a universal key-in-knob/lever cylinder; the 1579 Series is a knob and lever cylinder for Sargent; and the 1599 is a key-in-knob replacement cylinder.
10) What do I order for a deadbolt rather than a mortise lock body?
The Corbin Russwin 487K15 plug is intended for Corbin Russwin mortise lock assemblies. For deadbolt work, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
11) Which cylinders look like substitutes for the 487K15 but will not work in a mortise lock?
Several nearby cylinder parts serve different hardware entirely. 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 deadlock, and the 4026 is a five pin tumbler cylinder pull for the Adams Rite 5017 wood door deadlock. The BEST 12E Series dummy rim cylinder at 1-5/32" diameter is non-keyed. None of these replace a 1-3/8" Corbin Russwin mortise cylinder plug in the 57B2 keyway.
12) How does the 487K15 pin count compare with the other cylinders I might spec?
The Corbin Russwin 487K15 uses a 7-pin tumbler configuration in the X Class keying platform. The BEST 1CDF is also a 7-pin core, while the Detex MC65, Schlage 20-021, 20-022 and 20-057, and the Falcon A23161-05 G are 6-pin. The BEST 1C5 and the Adams Rite 4036 are 5-pin, as is the Medeco 1065244 rim lazy motion cylinder with Emtek tailpiece.
13) Is the 487K15 rated for high traffic commercial doors, or is it a residential part?
Commercial. It is classified as a commercial door hardware component and built for mortise lock systems in offices, schools, healthcare, government buildings, retail, multi-tenant residential, and industrial facilities where cylinders get heavy daily use.
14) Is the 487K15 appropriate for residential handleset hardware?
The Corbin Russwin 487K15 is a commercial cylinder part built for commercial mortise lock systems in facilities such as offices, schools, and healthcare buildings. For residential-style handleset hardware, the Emtek CY4 cylinder is sold each as an Emtek part, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
