Corbin Russwin 292K98 77A1 626 – Frequently Asked Questions

1) What keyway does the 292K98 77A1 plug use, and will it work in my existing key system?
The plug is cut for the Corbin Russwin 77A1 keyway. It will accept keys from a 77A1 system only, so it works if your building is already keyed in 77A1. A different Corbin Russwin keyway, or another brand's keyway, will not key to this plug.
2) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 292K98 77A1?
The Corbin Russwin 292K98 77A1 is a 7-pin plug replacement cylinder part for 1-3/4 in. mortise cylinder applications - it is the plug alone, for rekeying and cylinder servicing, not a complete housing. If the opening needs a whole mortise cylinder, the Detex MC65 is a 1-1/8 in. 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1. Those are assembled cylinders you install in the lock body; the 292K98 goes inside a Corbin Russwin housing you already have.
3) We want to stop pinning cylinders by hand - what is the interchangeable-core alternative to a 7-pin Corbin Russwin mortise plug?
The 292K98 77A1 is a conventional 7-pin plug, so rekeying means disassembling the cylinder at the bench. If you would rather pull and swap cores in the doorway, BEST interchangeable core products cover that: the 1CDF is a drill-resistant patented 7-pin brass interchangeable core in the 150 series, the 1CB is a Peaks 150 series interchangeable core, and the 1C5 is a standard 5-pin core. Schlage's 20-057 is a 6-pin full-size interchangeable core rim cylinder, and the 20-057-C is an FSIC core in the C keyway. Moving to cores changes the housings you need, so it is a system decision rather than a drop-in for the Corbin Russwin plug.
4) My exit device takes a rim cylinder - can I use the Corbin Russwin 292K98 77A1?
No. The 292K98 77A1 is a plug for 1-3/4 in. mortise cylinder applications, so it will not serve a rim-prepped device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal tailpiece cam; pick the cam orientation the device calls for. The BEST 12E series dummy rim cylinder, at 1-5/32 in. diameter, fills a rim prep where no key function is needed.
5) I need a whole cylinder, not a plug. What else does ZenSupply carry for commercial mortise applications?
For a complete mortise cylinder, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in Schlage C keyway. Note both are on their own keyways, so neither will key into a Corbin Russwin 77A1 system the way the 292K98 plug does.
6) Is the 292K98 plug suitable for a rim cylinder or an interchangeable core system?
No. It's a mortise-type plug sized for 1-3/4 inch mortise cylinder housings. For a rim cylinder, look at the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam), both 6-pin. For an interchangeable core setup, the BEST 1C 5-pin core or the 1CDF 7-pin drill-resistant core are the equivalent parts.
7) Does the 292K98 77A1 come with keys?
No keys are part of the 292K98 77A1 plug. It's a bare 7-pin plug in the 77A1 keyway, intended to be pinned by a locksmith to an existing system. If you need a cylinder supplied with cut keys, the Schlage 20-021 and 20-022 rim cylinders ship with two keys, and the Falcon A23161-05 G key-in-lever cylinder comes keyed different with two cut keys.
8) What do I use for a key-in-knob or key-in-lever cylinder instead of the Corbin Russwin 292K98 mortise plug?
The 292K98 77A1 plug is dimensioned for mortise cylinder housings, not knob or lever cylinders. For knob and lever bodies, Kaba Ilco offers the 1539 universal key-in-knob/lever cylinder, the 1599 key-in-knob replacement cylinder, and the 1579 knob and lever cylinder made for Sargent locks. Falcon's A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, supplied keyed different with two cut keys.
9) Is a 5-pin cylinder an acceptable stand-in for the 7-pin Corbin Russwin 292K98 plug?
Not within a Corbin Russwin 77A1 system. The 292K98 77A1 uses a 7-pin tumbler arrangement in the proprietary 77A1 keyway, which is what carries the key control and keying in that system; a 5-pin cylinder in a different keyway will not accept those keys. Five-pin cylinders such as the Adams Rite 4036 mortise cylinder or the BEST 1C5 standard 5-pin core belong to their own keying systems and are chosen when you are building or matching one of those, not when servicing a 77A1 masterkey system.
10) We have aluminum storefront with Adams Rite hardware - which cylinder product fits that rather than the Corbin Russwin plug?
The Corbin Russwin 292K98 77A1 plug is made for 1-3/4 in. mortise cylinder housings in commercial mortise locks, which is a different prep from a narrow stile storefront lock. Adams Rite covers that opening directly: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for the MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch. The 4036 mortise cylinder is a Grade 1 five-pin cylinder for those lock bodies.
11) What finishes is the Corbin Russwin 292K98 7-pin plug available in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder collar and trim already on the door, since the plug face is the visible part once the cylinder is assembled.
12) Is this Corbin Russwin plug appropriate for commercial buildings or light residential doors?
It's a commercial part. The 292K98 is built for commercial mechanical lock systems, and the typical uses are office buildings, schools, healthcare, government facilities, retail, warehouses and multi-tenant residential. For a house deadbolt, a residential replacement cylinder such as the Kaba Ilco 1549 key-in-deadbolt cylinder is the closer fit.
13) What is the difference between the Corbin Russwin 292K98 77A1 and a Medeco retrofit cylinder for an Emtek handleset?
They serve different lock platforms. The 292K98 77A1 is a Corbin Russwin 7-pin mortise plug in the 77A1 keyway, offered in 606 satin brass and 626 satin chrome, and it goes into commercial Corbin Russwin mortise cylinder housings. The Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Emtek's own CY4 is a replacement cylinder for Emtek hardware. Choose by the lock brand and prep on the door.
