Corbin Russwin 487K13 57A1 626 – Frequently Asked Questions

1) Is the Corbin Russwin 487K13 a complete mortise cylinder or just the plug?
It is the plug only, not a full cylinder. The 487K13 is a 7-Pin X Class replacement plug for 1-1/4 inch mortise cylinder housings, cut for the 57A1 keyway. If your cylinder shell, cam, and springs are fine and you only need to change the keying core of the plug, this is the part. If the whole cylinder body is damaged or you need a cam and shell too, order a complete mortise cylinder instead.
2) Will a Detex MC65 or Adams Rite 4036 key the same as the Corbin Russwin 487K13?
No. The 487K13 plug uses the proprietary Corbin Russwin 57A1 keyway and accepts the matching Corbin Russwin key blanks and master key systems. The Detex MC65 is cut for the Schlage C keyway, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder, so neither will run on a 57A1 key. Keep the keyway consistent if the opening is on an existing Corbin Russwin master key system.
3) We want to be able to rekey doors without pulling cylinders. What should we use instead of the 487K13?
The 487K13 is a fixed plug that has to be pinned into a 1-1/4 inch mortise cylinder housing. For swap-in-place rekeying, look at interchangeable core products: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill resistant patented 7-pin brass interchangeable core in the 150 Series, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
4) My opening uses a rim exit device, not a mortise lock. Can I use the 487K13?
No. The 487K13 plug is built for 1-1/4 inch mortise cylinder housings. Rim devices take a rim cylinder: 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. Pick the cam orientation your device calls for.
5) What finishes does the Corbin Russwin 487K13 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick to match the cylinder collar and lock trim already on the door, since the plug face is the visible part around the keyhole. 626 Satin Chrome is the usual match for brushed chrome or satin nickel trim; 606 for brass openings.
6) What does X Class mean on a Corbin Russwin 7-pin plug?
X Class is Corbin Russwin's high-security pin class. On the 487K13 the 7-pin X Class arrangement is what gives the added key control and pick resistance the description calls out, and it means the plug has to be keyed on X Class blanks in the 57A1 section, not standard blanks. Plan the keying with your locksmith or key control records before installing.
7) Can I use this plug in a residential deadbolt or knob lock?
No. The 487K13 is a commercial mortise cylinder part, made for mortise lock assemblies. For a residential key-in-knob or deadbolt replacement, a key-in-knob type cylinder such as the Kaba Ilco 1599 key-in-knob replacement cylinder or the Kaba Ilco 1549 key-in-deadbolt cylinder is the right family of part.
8) Is a rim cylinder the same thing as this mortise plug?
No, and they are not interchangeable. A mortise cylinder threads into the lock case and drives a cam; a rim cylinder mounts through the door and drives a tailpiece, as on the Schlage 20-021 with vertical tailpiece cam or the 20-022 with horizontal cam. If your device is an exit device or a rim latch, you want a rim cylinder, not the 487K13 mortise plug.
9) What is the simpler option if I only need to rekey a key-in-knob or key-in-lever lock?
The 487K13 is a mortise cylinder plug and will not serve a knob or lever cylinder. For those, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway supplied keyed different with two cut keys.
10) The door is an aluminum storefront with an Adams Rite MS1847 deadlock. Is the 487K13 what I need?
Not for that hardware. The 487K13 is a plug for 1-1/4 inch mortise cylinder housings. For MS1847 deadlock and deadlatch openings, the Adams Rite 4024 is a cylinder pull with trim plate mounting and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws. On a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is made for the 5017 wood door deadlock and deadlatch.
11) I need seven pins for key control. Which comparable parts also run 7-pin?
The Corbin Russwin 487K13 is a 7-Pin X Class plug, which is where its pick resistance and key control come from. Among the alternatives, the BEST 1CDF is a 7-pin drill resistant patented interchangeable core in brass. Most of the other cylinder options are 5- or 6-pin, such as the BEST 1C5 standard 5-pin core and the Schlage 20-021 6-pin rim cylinder.
12) Is the 487K13 suitable for a school or hospital keying program?
Yes, that is its intended use. It is a commercial-grade part used in office buildings, schools, healthcare, government and municipal buildings, retail, industrial facilities, and multi-tenant residential, where the 7-pin X Class plug and 57A1 keyway support restricted master key systems across many doors.
13) I need a non-keyed filler for an opening. Is the 487K13 an option?
No, the 487K13 is a working 7-pin plug that gets pinned and keyed. If you need a cylinder that fills the prep without operating, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the piece for that application.
14) Can I match the 487K13 finish to other cylinders on the same door?
The 487K13 plug comes in 606 Satin Brass and 626 Satin Chrome, so it can be matched to most commercial trim on a mortise opening. If the door also carries a full size interchangeable core, the Schlage 20-057-C is supplied in 643E Aged Bronze with the C keyway, which is a different finish family than the two the 487K13 offers.
