Corbin Russwin 292K98 77B2 626 – Frequently Asked Questions

1) Is the Corbin Russwin 292K98 a complete mortise cylinder or just the plug?
It is the plug only, not a full cylinder. The 292K98 77B2 is a 7-pin plug meant to be installed into a compatible Corbin Russwin mortise cylinder housing sized for 1-3/4 inch mortise applications. If you need a complete keyed cylinder for a mortise lock body, order a full mortise cylinder instead. For a full cylinder from another line, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin unit, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in Schlage C keyway.
2) I need a replacement cylinder for a rim exit device, not a mortise lock. Is this the right part?
No. The 292K98 is a plug for a mortise cylinder, and mortise cylinders thread into a mortise lock body. Rim exit devices take a rim cylinder with a tailpiece. For that application look at the Schlage 20-021 rim cylinder with vertical tailpiece cam or the 20-022 with horizontal tailpiece cam, both 6-pin and supplied with two keys.
3) Is the 292K98 an interchangeable core, so I can swap it without pulling the cylinder?
No. It is a mortise cylinder plug, a rebuild component that goes into a cylinder shell, not a small-format or full-size interchangeable core you turn out with a control key. If you want core-swap serviceability across a facility, that is an IC system: the BEST 1C 5-pin core, the BEST 1CDF drill-resistant 7-pin core, or Schlage full-size interchangeable cores such as the 20-057 with convertible tailpiece cam.
4) I want 7-pin key control but on an interchangeable core system instead of a mortise plug - what is the alternative to the Corbin Russwin 292K98?
The 292K98 77B2 uses a 7-pin tumbler design with the Corbin Russwin 77B2 keyway for controlled key duplication, but it is a plug for a mortise cylinder assembly. For 7-pin key control in an interchangeable core format, the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass core in the 150 series. The BEST 1CB Peaks 150 series core is another interchangeable core option, and the BEST 1C is a standard 5-pin core.
5) My exit device takes a rim cylinder - can I use the Corbin Russwin 292K98 for that?
No. The 292K98 77B2 is sized for 1-3/4 inch mortise cylinder housings, which are threaded and distinct from rim cylinders that mount behind the door with a tailpiece. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the Schlage 20-022 is the same in a horizontal tailpiece cam. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
6) What is the 77B2 keyway and can a locksmith cut keys for it?
77B2 is a Corbin Russwin keyway used for restricted key duplication and system-level keying in commercial and institutional buildings. Ordering the plug in 77B2 keeps a replacement on the same key system as the rest of the openings, which is the point of specifying it rather than an open keyway. Keys have to be cut on 77B2 blanks.
7) Why choose a 7-pin plug over a 6-pin for a commercial lock system?
Seven pins give more usable key differs and tighter key control than a 5- or 6-pin plug, which matters when you are running a master keyed system across a whole facility. It also means the plug is not interchangeable with 6-pin hardware. A 6-pin comparison point in the same category is the Detex MC65 mortise cylinder.
8) I need to rekey a key-in-lever or key-in-knob lock, not a mortise cylinder - what should I order instead of the Corbin Russwin 292K98?
The 292K98 77B2 serves mortise cylinder assemblies only. For key-in-knob and key-in-lever bodies, the Kaba Ilco 1539 is a universal key-in-knob/lever cylinder and the Kaba Ilco 1599 is a key-in-knob replacement cylinder; the Kaba Ilco 1579 is the knob and lever cylinder for Sargent locks. 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.
9) For a narrow stile aluminum storefront with an Adams Rite deadlock, is the Corbin Russwin 292K98 the right cylinder part?
The 292K98 77B2 is a 7-pin plug for 1-3/4 inch Corbin Russwin mortise cylinder assemblies and is aimed at commercial mechanical lock systems generally. For Adams Rite deadlock hardware specifically, the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847. On wood doors, the 4026 five pin tumbler cylinder pull is built for the Adams Rite 5017 wood door deadlock and deadlatch.
10) I need a keyed deadbolt cylinder for a residential handleset - is the Corbin Russwin 292K98 usable there?
The 292K98 77B2 is classified for commercial mechanical lock applications and fits Corbin Russwin mortise cylinder assemblies. Handleset and deadbolt retrofits call for a different family: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. The Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
11) What finishes does the Corbin Russwin 292K98 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the visible face of the cylinder and the surrounding trim, since the plug face sits flush at the keyhole. 626 Satin Chrome is the usual match for brushed chrome or satin nickel hardware; 606 goes with brass trim.
12) Is this plug suitable for high traffic institutional doors?
Yes. It is a commercial-rated replacement part intended for high-traffic institutional and commercial facilities, including schools, hospitals, government buildings, offices, retail, multi-tenant residential and warehouses. It is not a residential item.
13) The opening only needs a keyed appearance, not real keying - is the Corbin Russwin 292K98 overkill?
The 292K98 77B2 is a working 7-pin plug built for key control and system-level key management, so it is more than a blank opening needs. Where a non-functioning cylinder will do, the BEST 12E series dummy rim cylinder has a 1-5/32 inch diameter. Note the 12E is a rim format, not a mortise one.
14) Does the Corbin Russwin 292K98 come in a chrome finish, or do I have to switch brands to match satin chrome hardware?
No brand change is needed. The 292K98 77B2 plug is offered in 606 Satin Brass and 626 Satin Chrome. For comparison, the Schlage 20-057-C full size interchangeable core cylinder with C keyway is supplied in 643E Aged Bronze.
