Corbin Russwin 487K19 27B2 626 – Frequently Asked Questions

1) I need a replacement cylinder for a Sargent or Kwikset lock, not Corbin Russwin. Is this the right part?
No. The 487K19 plug only fits Corbin Russwin mortise cylinder assemblies with a 27B2 keyway. For a Sargent knob or lever, the Kaba Ilco 1579 cylinder is made for Sargent. For a Kwikset single cylinder deadbolt, the Medeco 1012040 6-pin lazy motion rim cylinder is the retrofit part. Neither shares anything with a Corbin Russwin mortise plug.
2) I need a complete mortise cylinder, not just a plug - what should I order instead of the Corbin Russwin 487K19?
The 487K19 is a 7-pin X Class plug for 1-3/4 inch mortise cylinder applications - it is the keyed core assembly that goes inside a Corbin Russwin mortise housing, not a complete cylinder you can thread into a lock case. If the door needs a whole mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder with a Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security. Both are standalone cylinders rather than plugs.
3) My facility uses interchangeable cores rather than fixed cylinders - what is the equivalent of the 487K19 in that system?
The Corbin Russwin 487K19 is a 7-pin X Class plug with the 27B2 keyway, built for Corbin Russwin mortise cylinder assemblies as a fixed-cylinder replacement part. For an interchangeable-core program, the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass core in the 150 series, 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-C is a full size interchangeable core in the C keyway. Cores swap without pulling the housing; the 487K19 plug is serviced inside the Corbin Russwin cylinder.
4) The exit device on my door takes a rim cylinder - will the Corbin Russwin 487K19 work there?
No. The 487K19 is a plug sized for 1-3/4 inch mortise cylinder applications, so it has no cam or tailpiece to drive a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, the 20-022 is the same cylinder with a horizontal tailpiece cam, and the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Confirm which cam orientation your device requires before ordering.
5) What do I order for a key-in-lever or key-in-knob lock instead of the Corbin Russwin 487K19?
The 487K19 is a mortise cylinder plug and does not fit knob or lever lock chassis. For those, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent locks, the 1599 is a key-in-knob replacement cylinder, and 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. For deadbolts, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
6) Why choose a 7-pin X Class plug instead of a standard 5- or 6-pin cylinder?
The X Class 7-pin configuration is a key control platform: keys are restricted, so duplication is controlled, and the plug gives added pick resistance. That matters when you are standardizing keying across a building and do not want blanks cut off-site. A conventional 5- or 6-pin cylinder, like the BEST 1C five-pin core or the Schlage 20-021 six-pin rim cylinder, is simpler but does not give you that level of key control.
7) Do I have to order keys separately with the 487K19 plug?
Plan on it. The 487K19 is supplied as a cylinder plug in the 27B2 keyway; unlike complete cylinders such as the Schlage 20-022 rim cylinder that ship with 2 keys, a plug is a service component and keys come from your 27B2 key system records.
8) Is there a simpler lower-pin-count alternative if I do not need the 7-pin X Class key control of the 487K19?
The 487K19 carries a 7-pin X Class configuration for enhanced key control and pick resistance. Where that level of restricted keying is not required, the Adams Rite 4036 mortise cylinder uses five-pin security, and the Detex MC65 is a 6-pin mortise cylinder. Among cores, the BEST 1C5 is a standard 5-pin cylinder core. Fewer pins means a shorter keying chart and no patented-key control program to administer.
9) I have an aluminum storefront with an Adams Rite MS1847 deadlock - does the Corbin Russwin 487K19 plug apply?
The 487K19 is a Corbin Russwin plug for 1-3/4 inch mortise cylinder assemblies and is not the part that serves an MS1847 opening on its own. For that hardware, the Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock systems, and the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847. For a wood door, the 4026 five pin tumbler cylinder pull is intended for the Adams Rite 5017 wood door deadlock/deadlatch.
10) I need a non-keyed filler for a cylinder hole - is the 487K19 the right part?
No. The 487K19 is a keyed 7-pin X Class plug with the 27B2 keyway, so it is an operating component. For an opening that needs a cylinder present but no key function, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the dummy part. Confirm that your prep is a rim hole before ordering it.
11) For a residential handleset or Kwikset deadbolt retrofit, is the Corbin Russwin 487K19 an option?
The 487K19 is designated for commercial use as a Corbin Russwin mortise cylinder replacement part, so it is not a residential retrofit piece. For those jobs, the Medeco 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 rim lazy motion 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. Emtek's own CY4 cylinder is also a parts-level option.
12) Is the 487K19 suitable for a commercial building or is it residential hardware?
Commercial. The 487K19 plug is classified commercial and is used in office buildings, schools, healthcare, retail, industrial and warehouse space, multi-tenant residential, and government facilities. It's a service part for keeping installed Corbin Russwin cylinders in the existing key system rather than replacing whole locksets.
13) What finishes does the Corbin Russwin 487K19 come in, and can I match it to other brands' cylinders?
The 487K19 plug is offered in 606 Satin Brass and 626 Satin Chrome. Matching across brands depends on what the peer publishes: the Schlage 20-057-C full size interchangeable core, for example, is listed in 643E Aged Bronze, which is a darker bronze tone rather than a satin brass or satin chrome. Where a door mixes hardware, pick the plug finish that matches the visible mortise cylinder ring rather than the lock body.
