Corbin Russwin 487K17 57B2 626 – Frequently Asked Questions

1) What keyway does the Corbin Russwin 487K17 plug come in, and can it be keyed into my existing master key system?
The plug is cut for the Corbin Russwin 57B2 keyway. If your building already runs 57B2, it drops into that key hierarchy and can be keyed alike, keyed different, or mastered with the rest of the system. If your openings are on a different Corbin Russwin section, the plug won't accept those keys.
2) Can I use the Corbin Russwin 487K17 plug in an Adams Rite or Kaba Ilco cylinder?
No. It's cut for Corbin Russwin 1-1/2 inch mortise cylinder housings and the 57B2 keyway, so it won't seat in another manufacturer's body. For an Adams Rite deadlock you'd want a purpose-built cylinder such as the Adams Rite 4036 five-pin mortise cylinder; for key-in-knob or lever replacement across mixed brands, the Kaba Ilco 1539 universal cylinder is the substitute to look at.
3) What should I order instead of the Corbin Russwin 487K17 plug if I need a complete mortise cylinder rather than just the plug?
The Corbin Russwin 487K17 is a 7-pin X Class replacement plug for 1-1/2 inch mortise cylinder housings, so it assumes the housing is already in the door. If you need a whole mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 Series. Note that both of those are complete cylinders on their own keyways, not Corbin Russwin 57B2 plugs, so they will not key into an existing 57B2 master system.
4) If I want to standardize on interchangeable cores instead of a keyed plug, what are my options?
The 487K17 is a fixed 7-pin X Class plug tied to the Corbin Russwin 57B2 keyway, so rekeying means pinning the plug. If you would rather swap cores by hand, 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 core. On the Schlage side, the 20-057 and 20-057-C are full size interchangeable core cylinders. Each of these runs on its own key system rather than 57B2.
5) I need a cylinder for a key-in-lever or deadbolt, not a mortise lock - what replaces the 487K17 there?
The 487K17 plug fits 1-1/2 inch mortise cylinder housings, which is the wrong format for knob, lever, and deadbolt prep. For those, Kaba Ilco offers the 1539 Series key-in-knob/lever universal cylinder, the 1599 key-in-knob replacement cylinder, the 1549 key-in-deadbolt cylinder, and the 1579 knob and lever cylinder built for Sargent. Falcon also lists the A23161-05 G key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys.
6) What finishes is the 487K17 mortise cylinder plug available in?
Two: 606 Satin Brass and 626 Satin Chrome. Satin Chrome is the one to pick if the rest of your trim is 626 satin chrome or brushed nickel-look hardware; Satin Brass matches 606 brass openings. On a cylinder plug only the visible face shows, so match it to the cylinder ring and rose already on the door.
7) Why choose a 7-pin X Class plug instead of a standard 6-pin cylinder?
The seven-pin X Class configuration gives tighter key control, which makes unauthorized key duplication harder and supports deeper master key hierarchies than a six-pin setup. That matters on schools, hospitals, and government buildings where the key system spans many doors. If you don't need restricted key control, a standard commercial cylinder like the Schlage 20-021 6-pin rim cylinder covers basic keyed function, though it's a rim cylinder rather than a mortise plug.
8) Is a rim cylinder like the Schlage 20-021 an acceptable substitute for a 487K17 mortise plug?
No. The 487K17 is a plug for a 1-1/2 inch threaded mortise cylinder used in Corbin Russwin mortise lock hardware. The Schlage 20-021 and 20-022 are rim cylinders, differing from each other in tailpiece cam orientation - vertical on the 20-021 and horizontal on the 20-022 - and rim cylinders mount through the door behind a rim exit device, not into a mortise lock case. They are different formats and are not interchangeable.
9) Does the 487K17 work on Adams Rite narrow stile deadlocks?
The 487K17 is a Corbin Russwin 57B2 plug for 1-1/2 inch mortise cylinder housings used with Corbin Russwin mortise lock hardware. Adams Rite narrow stile openings are served by their own parts: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws, both for the MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull for the 5017 wood door deadlock/deadlatch.
10) Can I use the 487K17 to upgrade a residential handleset or Kwikset deadbolt to high security?
The 487K17 is a commercial replacement part for Corbin Russwin mortise cylinder housings, so residential handleset and deadbolt prep is outside its format. Medeco covers that side with retrofit cylinders: the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 5-pin lazy motion rim cylinder with Emtek tailpiece, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder sold each.
11) What is the closest 7-pin alternative to the 487K17 if I am not locked into the Corbin Russwin 57B2 system?
Pin count wise, the closest peer is the BEST 1CDF, a 7-pin drill resistant patented interchangeable core in brass, 150 series. The difference is format and key system: the 487K17 is a fixed 7-pin X Class plug on the Corbin Russwin 57B2 keyway that pins into a 1-1/2 inch mortise housing, while the 1CDF is a removable core on the BEST system. Pick the 487K17 to stay inside an existing 57B2 hierarchy, and the 1CDF if you are building a new BEST-keyed program.
12) Is the 487K17 an aftermarket plug or genuine Corbin Russwin?
Genuine Corbin Russwin cylinder component, which is why the fit in existing Corbin Russwin mortise lock assemblies is exact. It's classed as commercial hardware, not residential, and is intended for replacement and rekey work.
13) I only need a non-keyed filler for an opening - is the 487K17 the right part?
No. The 487K17 is a keyed 7-pin X Class plug in the 57B2 keyway, built for real key control in commercial mortise locks. 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-format part. It is a rim-format dummy, so it does not thread into a 1-1/2 inch mortise housing.
