Corbin Russwin 487K19 57A2 626 – Frequently Asked Questions

1) Will the 487K19 plug work in my Corbin Russwin mortise cylinder if my keys are a different keyway?
No. The 487K19 comes factory configured with the 57A2 keyway, so it only accepts keys cut on 57A2. Dropping it into a housing on a different Corbin Russwin keyway means your existing keys won't operate it. Match the keyway to your system before ordering.
2) Is the 487K19 a 6-pin or 7-pin plug, and does that matter for my keying system?
It's a 7-pin plug in Corbin Russwin's X Class configuration. Pin count has to match the system you are keying into, so a 7-pin plug belongs in a 7-pin X Class master key system. If your facility runs 6-pin Corbin Russwin cylinders, the keys and pinning won't carry over.
3) I'm replacing a rim cylinder on an exit device. Is the 487K19 the right part?
No, it isn't. The 487K19 is a mortise cylinder plug; rim cylinders mount through the door behind a rim exit device and use a tailpiece. For that job ZenSupply carries the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal cam, plus the BEST 12E dummy rim cylinder at 1-5/32 inch diameter where no keying is needed.
4) I need a complete mortise cylinder, not just a plug. What should I order instead of the Corbin Russwin 487K19?
The 487K19 is a replacement cylinder plug, the keyed core component that drops into an existing mortise cylinder housing. If the whole cylinder needs to be replaced, look at a complete mortise cylinder instead: the Adams Rite 4036 is a Grade 1 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. Those arrive as a finished cylinder assembly rather than a plug that must be pinned into a housing you already own.
5) My openings use interchangeable cores. Is the Corbin Russwin 487K19 the right part, or do I need something else?
The 487K19 is a 7-pin X Class mortise cylinder plug for a fixed mortise cylinder housing, not an interchangeable core. Facilities standardized on IC keying go a different direction: the BEST 1C Series is a standard 5-pin cylinder core, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in the 150 Series, and the Schlage 20-057-C is a full-size interchangeable core in the C keyway. Those pull and swap with a control key; the 487K19 is pinned into the cylinder.
6) The lock is a rim device, not a mortise lock. Can I use the Corbin Russwin 487K19?
No. The 487K19 is sized for 1-3/4 inch mortise cylinder applications and fits mortise housings. Rim exit devices take 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 cylinder with a horizontal tailpiece cam, while the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to what the device requires.
7) I need a complete mortise cylinder, not a plug. What else does ZenSupply carry?
For a full mortise cylinder rather than a replacement plug, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Neither works in a Corbin Russwin 57A2 key system, so they suit new keying rather than matching existing Corbin Russwin keys.
8) What model number do I give my locksmith to order this Corbin Russwin plug?
Specify model 487K19 57A2, then the finish, either 606 Satin Brass or 626 Satin Chrome. The 487K19 identifies the 7-pin X Class plug and 57A2 identifies the keyway.
9) Does the 487K19 come with keys cut, or do I need to have it keyed?
The plug ships factory configured to the 57A2 keyway, which sets which key blanks fit it, but the pinning and cutting are keying work done to your system. Plan on a locksmith pinning it to your existing 7-pin X Class change or master key. By contrast, some complete cylinders we carry include cut keys, such as the Falcon A23161-05 G keyed different with 2 cut keys.
10) What is the difference between the Corbin Russwin 487K19 plug and a key-in-knob or key-in-lever cylinder?
Different lock bodies entirely. The 487K19 is a mortise cylinder plug with the 57A2 keyway for Corbin Russwin mortise lock systems. Knob and lever locks take a cylinder built for that chassis: the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and 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. None of those go into a mortise cylinder housing.
11) Is a simpler 5-pin cylinder an option if I do not need the X Class key control of the Corbin Russwin 487K19?
Yes, if the opening does not need patented key control. The 487K19 uses a 7-pin X Class plug for enhanced key control and pick resistance. Where that is more than the door calls for, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the BEST 1C Series is a standard 5-pin core. Note that dropping to 5 pins means the opening leaves whatever restricted keyway system the X Class plug was part of.
12) We are replacing cylinders on aluminum storefront doors with Adams Rite deadlocks. Does the Corbin Russwin 487K19 work there?
Not directly. The 487K19 is a plug for Corbin Russwin mortise cylinder housings. Adams Rite narrow stile deadlocks are served by their own parts: the Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock and deadlatch systems, the 4025 is a five-pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five-pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock. The 4036 mortise cylinder covers a minimum door thickness of 1/2 inch, which suits narrow stile work.
13) I need a cylinder for a residential handleset or deadbolt, not a commercial mortise lock. What takes the place of the Corbin Russwin 487K19?
The 487K19 is a commercial part for mortise lock systems. Handleset and deadbolt retrofits are covered by the Medeco rim-type cylinders: 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 lazy motion rim 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. The Emtek CY4 cylinder is sold each as an Emtek part.
14) Some openings only need the look of a cylinder with no key function. Is the Corbin Russwin 487K19 usable that way?
No, the 487K19 is a working keyed plug configured with the 57A2 keyway for Corbin Russwin keying systems. For a non-functioning opening where the hardware just needs to look complete, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter serves that purpose. Use the keyed 487K19 only where the door is actually locked and keyed.
15) For a deadbolt cylinder replacement, what compares to the Corbin Russwin 487K19?
The 487K19 is a mortise cylinder plug rather than a deadbolt cylinder. For deadbolt applications the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the 1539, 1579 and 1599 Series cylinders are also listed with a deadbolt function. Those are complete cylinders for deadbolt chassis, whereas the 487K19 is the keyed plug that goes inside a mortise cylinder.
16) Is this a residential part or is it meant for commercial buildings?
Commercial. The 487K19 plug is a commercial mechanical lock component, used in office buildings, schools, hospitals, government facilities, retail, warehouses, and multi-tenant residential properties where Corbin Russwin mortise hardware is already installed.
