Corbin Russwin 487K19 57B1 626 – Frequently Asked Questions

1) Will the 487K19 plug work in my Corbin Russwin cylinder if my keys are a different keyway?
No. The 487K19 is cut for the 57B1 keyway, and a plug only accepts keys in the keyway it is machined for. If your building keying system runs a different Corbin Russwin keyway, this plug will not take your keys and cannot be altered to. Match the keyway stamped on your existing cylinder before ordering.
2) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 487K19?
The 487K19 is a 7-pin X Class cylinder plug with the 57B1 keyway, sold as a replacement part for an existing Corbin Russwin mortise cylinder housing rather than as a complete cylinder. If the housing itself is being replaced, a full mortise cylinder is the right order instead: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Both are complete cylinders, so they carry their own keyways and will not run on Corbin Russwin 57B1 keys.
3) We want to stop repinning plugs every time a tenant changes. What is an alternative to the Corbin Russwin 487K19 approach?
The 487K19 is a fixed plug that has to be pulled and repinned by a locksmith to change keying. An interchangeable core system changes keying with a control key instead: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in brass, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Moving to cores means changing the cylinder hardware in the openings, not just the plug, and puts the doors on a different keyway family than Corbin Russwin 57B1.
4) Will the Corbin Russwin 487K19 work in a key-in-lever or deadbolt lock?
No. The 487K19 is sized for 1-3/4 inch mortise cylinder applications. For key-in-knob and key-in-lever bodies the corresponding parts are the Kaba Ilco 1539 universal key-in-knob/lever cylinder, the Kaba Ilco 1599 key-in-knob replacement cylinder, the Kaba Ilco 1579 knob and lever cylinder for Sargent, and the Falcon A23161-05 G key-in-lever cylinder in a 6-pin G keyway. For deadbolts, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
5) What does 7-Pin X Class mean on a Corbin Russwin cylinder plug?
X Class is Corbin Russwin's restricted keyway program, and the 487K19 plug is drilled for seven pin chambers rather than the more common six. The extra chamber adds pick resistance and, more to the point for a facility, the key control that comes with a restricted keyway. It only works inside a 7-pin Corbin Russwin system; a 6-pin cylinder body will not accept it.
6) Can I use this plug to rekey a mortise lock instead of buying a whole new cylinder?
That's exactly what it's for. Swapping the 487K19 plug lets a locksmith change the keying or replace a worn plug without pulling and replacing the full cylinder or the mortise lock body. It's aimed at commercial service work, offices, schools, healthcare, and multi-tenant buildings keeping an existing Corbin Russwin system running.
7) I need a mortise cylinder, not a plug. What else is available?
For a complete mortise cylinder, the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in the Schlage C keyway. Neither will take a Corbin Russwin 57B1 key, so they suit new keying rather than matching an existing Corbin Russwin system.
8) Is a Corbin Russwin 487K19 plug the same thing as a BEST interchangeable core?
No, and they are not interchangeable. The 487K19 is a fixed plug that goes inside a conventional Corbin Russwin mortise cylinder. A BEST small format core such as the 1C5 five-pin core or the 1CDF drill resistant seven-pin core pulls out with a control key and requires a housing prepped for interchangeable core. If your openings run IC housings, a conventional plug is the wrong part.
9) Can a Schlage 20-021 rim cylinder be used in place of the Corbin Russwin 487K19?
No. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam. Rim cylinders mount through the door behind a rim exit device, while the 487K19 is a plug that fits inside a 1-3/4 inch Corbin Russwin mortise cylinder. They are different formats and the rim cylinders cannot be installed in a mortise housing.
10) Is there a lower pin count equivalent to the 7-pin Corbin Russwin 487K19 plug?
The 487K19 uses a 7-pin X Class configuration for key control and pick resistance. Comparable cylinder parts built on five pins include the BEST 1C Series standard 5-pin cylinder core and the Adams Rite 4036 five-pin mortise cylinder. Those are different products in different keying families, so they are options for a new opening rather than drop-in substitutes inside a Corbin Russwin 57B1 mortise housing.
11) Our aluminum storefront uses an Adams Rite deadlock. Is the 487K19 the right cylinder part for it?
No. The 487K19 is a Corbin Russwin mortise cylinder plug for commercial mortise lock assemblies. For Adams Rite storefront deadlocks, the matched parts are 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. The Adams Rite 4036 is the Grade 1 mortise cylinder used in those systems.
12) What is the residential handleset equivalent when the 487K19 is the wrong grade of product?
The 487K19 is a commercial cylinder part for mortise lock assemblies in high-traffic buildings. For residential handlesets and deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. The Emtek CY4 cylinder is also sold individually.
13) What finishes does the Corbin Russwin 487K19 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one matching the rest of the trim on the opening, since the plug face is the part you see through the escutcheon or rose.
14) We need a non-keyed filler for a door that only needs the look of a cylinder. Does the 487K19 cover that?
No. The 487K19 is a functioning 7-pin X Class keyed plug in the 57B1 keyway. For an opening that needs the appearance without keyed operation, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the item built for that purpose.
15) We want an aged bronze cylinder to match existing trim. Does the 487K19 come in that finish?
The 487K19 plug is offered in 606 satin brass and 626 satin chrome. If aged bronze is the requirement, the Schlage 20-057-C full size interchangeable core cylinder is furnished in 643E aged bronze with the C keyway, though it is an FSIC core rather than a Corbin Russwin mortise plug and runs on a different keying system.
