Corbin Russwin 487K13 77B1 626 – Frequently Asked Questions

1) Will a 77B1 keyway plug work in my existing Corbin Russwin master key system?
The 487K13 carries the 77B1 keyway, so it keys into a Corbin Russwin system already built on 77B1. If your building runs a different Corbin Russwin keyway, the key will not enter this plug, so match the keyway stamped on your existing cylinders before ordering. It's a 7-pin plug, which also means your pinning and key bitting have to be cut for a 7-pin chamber count.
2) Will the 487K13 plug fit a rim cylinder or a key-in-lever cylinder?
No. It is dimensioned for 1-1/4 inch mortise cylinder housings, so it does not go into rim or key-in-knob/lever cylinders. For a rim application, look at the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam) 6-pin rim cylinders. For key-in-knob or lever replacement, the Kaba Ilco 1599 key-in-knob cylinder covers that case.
3) My Detex exit device uses a 1-1/8 inch Schlage C mortise cylinder. Can I use this plug in it?
No. The 487K13 is a 1-1/4 inch format plug with a Corbin Russwin 77B1 keyway, so neither the size nor the keyway matches a 1-1/8 inch Schlage C cylinder. For that application the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder with the Schlage C keyway.
4) What should I use if I want an interchangeable core instead of a keyed plug like the Corbin Russwin 487K13?
The 487K13 77B1 is a fixed plug for a 1-1/4" Corbin Russwin mortise cylinder body, so rekeying means pinning the plug. If you want a core you can pull and swap by hand, the BEST 1CB 150 Series and the BEST 1CDF drill-resistant patented 7-pin brass 150 Series are interchangeable core cylinders, and the BEST 1C Series standard 5-pin core is the base core in that family. Schlage's 20-057 is a 6-pin full size interchangeable core, with the 20-057-C supplied in the C keyway. Those cores require the matching IC housing rather than a Corbin Russwin mortise cylinder shell.
5) Can the Corbin Russwin 487K13 77B1 be used on an exit device rim cylinder?
No. The 487K13 77B1 is a plug for a 1-1/4" mortise cylinder assembly, which threads into the lock case and drives a cam. Rim cylinders mount through the door face and drive a tailpiece for a rim exit device. For that opening, Schlage's 20-021 rim cylinder uses a vertical tailpiece cam and the 20-022 uses a horizontal tailpiece cam, both 6-pin and supplied with two keys; the 20-057 is the 6-pin FSIC version with a convertible tailpiece cam. Those are separate cylinder types, not substitutes for a mortise plug.
6) I manage a portfolio of commercial buildings. Can I use this plug to rekey doors instead of replacing whole cylinders?
That's exactly what it's for. Swapping the 487K13 77B1 plug into a compatible Corbin Russwin mortise cylinder lets you change key control without pulling the cylinder body or the lock, which keeps the lock case and trim untouched. It's a commercial-duty part intended for service and maintenance on existing Corbin Russwin hardware.
7) What is the difference between this X Class plug and an interchangeable core system?
Two different approaches to key control. The 487K13 is a fixed 7-pin plug that gets pinned and installed into a mortise cylinder, so rekeying means pulling the plug. An interchangeable core system lets you pull and replace the core with a control key and no disassembly, for example the BEST 1CB 150 Series interchangeable core or the 7-pin BEST 1CDF drill-resistant core, or Schlage's 20-057 FSIC rim cylinder. If you're standardizing a large facility for fast rekeying, the IC route is worth considering; if you're servicing existing Corbin Russwin mortise cylinders, stay with the plug.
8) What cylinder do I use for a deadbolt rather than a Corbin Russwin 487K13 mortise plug?
The 487K13 77B1 plug serves Corbin Russwin mortise cylinder assemblies. For deadbolt cylinders, Kaba Ilco's 1549 Series is a key-in-deadbolt cylinder, and Medeco's 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. Medeco's 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. Match the one that names your lock.
9) I need to rekey a key-in-lever lock, not a mortise lock - is the Corbin Russwin 487K13 the right part?
It is not. The 487K13 77B1 is a 7-pin X Class plug for a 1-1/4" mortise cylinder. Key-in-knob and key-in-lever locks take their own cylinder format: the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series 6-pin G keyway, keyed different with two cut keys, and Kaba Ilco offers the 1539 Series key-in-knob/lever universal cylinder, the 1599 key-in-knob replacement cylinder, and the 1579 knob and lever cylinder for Sargent. Those bodies will not seat in a mortise lock case.
10) My aluminum storefront has an Adams Rite deadlock - will the Corbin Russwin 487K13 work there?
Only if the door already carries a 1-1/4" Corbin Russwin mortise cylinder body, since the 487K13 77B1 is the plug for that assembly. For Adams Rite MS1847 deadlock and deadlatch systems, the 4024 cylinder pull mounts with a trim plate and the 4025 five-pin tumbler cylinder pull uses through-screws; the 4026 five-pin tumbler cylinder pull is the version for Adams Rite 5017 wood door deadlocks. The Adams Rite 4036 is the Grade 1 five-pin mortise cylinder itself, with a 1/2" minimum door thickness.
11) What finishes does the Corbin Russwin 487K13 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder housing and the trim on the rest of the opening, since the plug face is the part that shows through the collar.
12) Is this an aftermarket plug or a genuine Corbin Russwin part?
Genuine Corbin Russwin. The 487K13 77B1 is an authentic cylinder component, which matters on a plug because the tolerances and the keyway profile have to match the rest of the factory assembly for the key to turn cleanly.
13) Is there a cheaper non-keyed option if the opening does not actually need to lock?
If the door only needs the look of a cylinder with no keying, the BEST 12E Series dummy rim cylinder at 1-5/32" diameter fills the hole without a working key mechanism. The Corbin Russwin 487K13 77B1 is the opposite case - a working 7-pin X Class plug in the 77B1 keyway, intended where key control inside a Corbin Russwin keying system matters. Note the 12E is a rim format dummy, so it will not fill a 1-1/4" mortise cylinder housing.
