Corbin Russwin 487K17 57A2 626 – Frequently Asked Questions

1) Will the 487K17 plug work in my existing Corbin Russwin mortise cylinder?
It fits 1-1/2 inch Corbin Russwin mortise cylinder housings and is keyed to the 57A2 keyway with a 7-pin X Class configuration. Two conditions have to line up: the housing has to be the 1-1/2 inch mortise format, and your key system has to be on 57A2. A plug in a different keyway will not accept your existing keys, and a 6-pin housing will not take a 7-pin plug.
2) Can I use the 487K17 to re-key a Schlage or BEST cylinder?
No. The 487K17 is a Corbin Russwin plug on the 57A2 keyway and it will not go into another manufacturer's cylinder. For Schlage-based openings, a Schlage 20-021 or 20-022 rim cylinder (6-pin, vertical or horizontal tailpiece cam) is the parallel part, and the 20-057 FSIC rim cylinder if you run full-size interchangeable cores. For BEST small-format interchangeable core systems, the BEST 1C 5-pin core or the 1CDF drill-resistant 7-pin core are the replacements.
3) Will the Corbin Russwin 487K17 work in a key-in-knob or key-in-lever lock?
No. The 487K17 is a plug for 1-1/2 inch mortise cylinder housings. Key-in-knob and key-in-lever locks take a different cylinder body entirely. For those, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder on the RU/T Series 6-pin G keyway, keyed different with two cut keys. For a key-in-deadbolt, the Kaba Ilco 1549 Series is the matching part.
4) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 487K17?
The 487K17 is a replacement plug for 1-1/2 inch mortise cylinder applications, so it goes into an existing Corbin Russwin cylinder housing rather than replacing the whole cylinder. If the housing itself is damaged or missing, a complete mortise cylinder is the right call: 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. Both are full cylinders that thread into a mortise lock body, and neither uses the Corbin Russwin 57A2 keyway, so they would start a separate key system from the 487K17.
5) My exit device takes a rim cylinder, not a mortise cylinder. What do I use instead of the 487K17?
The 487K17 is sized for 1-1/2 inch mortise cylinder housings, which thread into a mortise lock body and are not interchangeable with rim prep. 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 6-pin rim cylinder with a horizontal tailpiece cam; pick the cam orientation your device calls for. If the facility runs interchangeable cores, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
6) I have an aluminum storefront door with an Adams Rite deadlock. Is the 487K17 the right cylinder part?
The 487K17 is a mortise cylinder plug for commercial mortise lock hardware and is not the storefront part. For an Adams Rite MS1847 deadlock or deadlatch, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws. For a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching item. If the storefront lock takes a standard threaded mortise cylinder, the Adams Rite 4036 Grade 1 mortise cylinder is the direct option.
7) What is X Class and does it matter for a building I'm re-keying?
X Class is Corbin Russwin's restricted key control platform. The 487K17's 7-pin X Class plug means keys are controlled rather than freely duplicated, which is the point of using it in offices, schools, healthcare, government buildings and multi-tenant residential where you need to know who holds a key. It only works as key control if the rest of your system is on the same X Class 57A2 keyway, so it is a part for extending or repairing an existing X Class system, not for starting a generic one.
8) I need a mortise cylinder for an aluminum storefront deadlock, not a plug. What should I use?
A plug like the 487K17 only serves an existing Corbin Russwin housing. For an aluminum storefront deadlock, the Adams Rite 4036 mortise cylinder is the five-pin Grade 1 unit built for that application, down to a 1/2 inch minimum door thickness. Adams Rite also makes cylinder pulls if the door has no other trim: the 4024 and 4025 for MS1847 deadlocks and the 4026 for the 5017 wood door deadlock.
9) How do I order the right 487K17 for my keying system?
Specify three things: the 57A2 keyway to match your existing X Class system, the 1-1/2 inch mortise format for your housing, and the finish (606 Satin Brass or 626 Satin Chrome). The model designation to reference is 487K17 57A2. Keying to your existing system is handled through your X Class key records, so have your key system on hand when you place the order.
10) I'm standardizing cylinders across a facility on interchangeable cores. Is the 487K17 the right approach?
No, it's the opposite approach. The 487K17 is a fixed keyed plug for a conventional Corbin Russwin mortise cylinder, so re-keying means pinning the plug. If your goal is field-swappable cores across a whole facility, look at an interchangeable core platform instead: BEST's 1CB 150 Series interchangeable core, the 1CDF 7-pin drill-resistant core, or Schlage's 20-057 full-size interchangeable core rim cylinder. Use the 487K17 where you are maintaining an existing conventional X Class system.
11) Can a BEST interchangeable core be used in place of the Corbin Russwin 487K17 plug?
They solve the key-control problem in different ways. The 487K17 is a 7-pin X Class plug that is pinned into a Corbin Russwin mortise cylinder housing on the 57A2 keyway. BEST interchangeable cores such as the 1C Series standard 5-pin core, the Peaks 1CB 150 Series core, and the 1CDF drill resistant patented 7-pin brass 150 Series core pull out with a control key and drop into BEST-prepped housings instead. To move to an interchangeable core system you would be changing the cylinder housing and the key system, not swapping a plug.
12) What is a simpler, lower-security alternative if I do not need X Class key control on a mortise cylinder?
The 487K17 uses a 7-pin X Class plug for elevated pick resistance and key control. Where a standard commercial pin stack is enough, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the Detex MC65 is a six-pin mortise cylinder on the Schlage C keyway. Both are conventional keyways rather than a restricted key control program, so keys can be duplicated without the controls an X Class system imposes.
13) What looks like a substitute for the 487K17 but will not actually function as a keyed cylinder?
Watch for dummy and residential-pattern cylinders. The BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter, so it fills the hole without keyed operation. The Emtek CY4 is a cylinder sold as a parts item for Emtek hardware. Medeco retrofit cylinders are also matched to specific residential platforms rather than commercial mortise housings: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. None of those serve as the 7-pin X Class plug for a 1-1/2 inch Corbin Russwin mortise cylinder.
14) Is this part suitable for high-traffic commercial doors, or is it residential grade?
Commercial. The 487K17 is a commercial-grade cylinder component built to Corbin Russwin's mortise cylinder tolerances, and the typical placements are office buildings, schools, hospitals, municipal buildings, retail, warehouses and multi-tenant residential. It is not a residential retrofit part.
15) The 487K17 comes in satin brass and satin chrome. What are my finish options if I need something else on a cylinder?
The 487K17 plug is offered in 606 satin brass and 626 satin chrome, which cover the two most common commercial trim finishes. If the opening calls for a darker finish and the application allows a full size interchangeable core, the Schlage 20-057-C is an FSIC cylinder on the C keyway in 643E aged bronze. Note that is a different cylinder format and key system, not a finish variation of the Corbin Russwin plug.
