Corbin Russwin 487K21 67B2 626 – Frequently Asked Questions

1) I need a whole mortise cylinder, not a plug. What else does ZenSupply carry?
For a complete mortise cylinder, look at the Detex MC65, a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, or the Adams Rite 4036 five-pin mortise cylinder, which is Grade 1 and rated for a 1/2 inch minimum door thickness. Both are assembled cylinders rather than plugs, so they suit a new opening or a housing swap. Neither runs the Corbin Russwin 67B2 keyway, so they will not key into an existing Corbin Russwin X Class system.
2) If I need a complete 2 inch mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 487K21?
The Corbin Russwin 487K21 is a replacement plug for 2 inch mortise cylinder applications, so it goes into an existing housing rather than standing alone. When the opening needs a whole cylinder, the Adams Rite 4036 is a complete mortise cylinder with five-pin security, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Both are ordered as assembled cylinders, not as plugs to be pinned into a Corbin Russwin housing.
3) What is the equivalent for a rim exit device instead of a mortise application?
The Corbin Russwin 487K21 plug is built for the 2 inch mortise cylinder format and will not serve a rim device. For rim applications the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam. If the facility runs full size interchangeable cores, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
4) Is a BEST interchangeable core the same thing as a Corbin Russwin 487K21 plug?
No. The 487K21 is a 7-pin X Class plug that is pinned into a 2 inch Corbin Russwin mortise cylinder housing. A BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass from the 150 series, and the BEST 1CB is a Peaks 150 series interchangeable core; those cores drop into BEST figure-eight core housings and are removed with a control key rather than being assembled into a mortise shell. The BEST 1C 5-pin core is a standard core in the same interchangeable family. None of them use the Corbin Russwin 67B2 keyway.
5) What does 7-Pin X Class mean on a Corbin Russwin cylinder plug?
X Class is Corbin Russwin's high security pinning platform, and this plug is built in the 7-pin configuration for added key control and pick resistance. Practically, that means it has to be pinned into an X Class system with the matching 67B2 keyway; it is not a drop-in for a standard 6-pin conventional Corbin Russwin cylinder.
6) If I want a rekeyable core I can swap without pinning, is this the right part?
No. The 487K21 plug has to be pinned by a locksmith to your bitting. If your goal is cores you can pull and change on the fly, an interchangeable core platform is the better route: the BEST 1C Series 5-pin core, the BEST Peaks 1CB 150 Series core, or the drill resistant BEST 1CDF 7-pin brass 150 Series core. Schlage's 20-057 FSIC rim cylinder is another full size interchangeable core option.
7) For a key-in-lever or key-in-knob lock, is the 487K21 the right cylinder?
No. The 487K21 is a mortise cylinder plug, and key-in-lever and key-in-knob locks take a different cylinder body. 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. Kaba Ilco offers the 1539 series key-in-knob and lever universal cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder.
8) What are the options if the opening is a deadbolt rather than a mortise lock?
The Corbin Russwin 487K21 plug serves 2 inch mortise cylinder housings. For deadbolt cylinders, the Kaba Ilco 1549 is a key-in-deadbolt cylinder listed for deadbolt function, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. The Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
9) Is there a lower-pin-count alternative if I do not need a 7-pin high security plug?
The Corbin Russwin 487K21 is a 7-pin X Class plug intended for high security keying systems with controlled key duplication. Where a standard five-pin cylinder is acceptable, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the BEST 1C is a standard 5-pin cylinder core. Those use their own keyways rather than the Corbin Russwin 67B2 profile, so they would not key into an existing 67B2 master system.
10) Which cylinder products look like substitutes for the 487K21 but are not?
Several cylinder-family items are not interchangeable with the Corbin Russwin 487K21 2 inch mortise plug. The BEST 12E series dummy rim cylinder at 1-5/32 inch diameter has no working pinning at all. The Adams Rite 4024 and 4025 are cylinder pulls for MS1847 deadlock and deadlatch systems, and the 4026 is a cylinder pull for the 5017 wood door deadlock, so they are pull trim rather than a plug. The Emtek CY4 is a residential-style parts cylinder sold each.
11) Do I get keys with the Corbin Russwin 487K21 plug?
Treat it as an unkeyed OEM component. It is sold as a replacement plug for Corbin Russwin cylinder parts, to be pinned into your existing keying system by a locksmith. If you need a cylinder that arrives cut and keyed, look at a complete keyed cylinder instead, such as the Falcon A23161-05 G six-pin key-in-lever cylinder, which ships keyed different with two cut keys.
12) Is this Corbin Russwin plug suitable for residential door hardware?
It is a commercial part. The 487K21 is built for commercial mechanical lock systems and gets specified in office buildings, schools, healthcare, government facilities, retail, warehouses and multi-tenant residential properties where a keyed system is already in place. For a single house door, a standard residential cylinder is the simpler buy.
13) Can I match the satin chrome or satin brass finish of the 487K21 with another brand's cylinder?
The Corbin Russwin 487K21 plug is offered in 606 satin brass and 626 satin chrome. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is cataloged in 643E aged bronze, which is a darker finish and will not visually match either 487K21 option. When finish continuity matters on a door face, pairing the 487K21 with the housing and trim already in the door is the closer match.
