Corbin Russwin 292K98 77B1 626 – Frequently Asked Questions

1) Is the Corbin Russwin 292K98 a complete mortise cylinder or just the plug?
It's the plug only, not a full cylinder. The 292K98 is a 7-pin replacement plug for 1-3/4 inch mortise cylinder applications, sold as a Corbin Russwin cylinder replacement part. If you need a whole cylinder body to drop into a lock, this is not it. If you're rebuilding or re-keying an existing Corbin Russwin mortise cylinder housing, the plug is the piece that carries the keyway and pin chambers.
2) Will the 292K98 plug work in a 1-1/8 inch mortise cylinder?
No. The 292K98 plug is sized for 1-3/4 inch mortise cylinder housings, so it will not serve a shorter 1-1/8 inch cylinder. For a 1-1/8 inch commercial mortise cylinder as a complete unit, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder we carry, though it is cut to the Schlage C keyway rather than a Corbin Russwin keyway.
3) What keyway is the Corbin Russwin 292K98 cut to, and will my existing keys work?
The plug is machined to the 77B1 keyway. Keys already operating a 77B1 system will enter it, but the plug arrives as a plug: pinning determines whether it turns on your key. For any other Corbin Russwin keyway family, 77B1 is the wrong blade profile and the key won't enter.
4) Will the 292K98 plug fit a Schlage or Sargent mortise cylinder housing?
Treat it as Corbin Russwin only. The 292K98 is built to integrate with compatible Corbin Russwin mortise cylinder assemblies, and plug diameter, tailpiece drive, and keyway differ between manufacturers. For Sargent knob and lever work, the Kaba Ilco 1579 cylinder is made for Sargent; for Schlage, the 20-series rim cylinders are the Schlage-native parts.
5) If the whole mortise cylinder needs replacing instead of just the plug, what should I order?
The Corbin Russwin 292K98 is a replacement plug for a 1-3/4 inch mortise cylinder, so it only helps when the existing housing and shell stay in the door. If the cylinder itself is being replaced, a complete mortise cylinder such as the Detex MC65, a 1-1/8 inch 6-pin mortise cylinder with a Schlage C keyway, or the Adams Rite 4036 Grade 1 mortise cylinder is the item to order instead. Those are assembled cylinders, not plugs, and they carry their own keyway rather than the Corbin Russwin 77B1.
6) Is a BEST interchangeable core an equivalent to the Corbin Russwin 292K98 plug?
No. The 292K98 is a 7-pin plug that drops into an existing Corbin Russwin 1-3/4 inch mortise cylinder shell and is machined to the 77B1 keyway. BEST interchangeable cores, such as the 1CB 150 Series core or the 1CDF drill resistant patented 7-pin brass core, are removable cores that require a figure-eight IC housing in the lock. The pin count can match at 7, but the two are not interchangeable in the same hardware.
7) My opening uses a rim exit device, not a mortise lock. Can I use the 292K98?
No. The 292K98 plug is sized for 1-3/4 inch mortise cylinder housings used in commercial mechanical lock systems. Rim exit devices take a rim cylinder, such as the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam; if the building is on full size interchangeable core, the Schlage 20-057 FSIC rim cylinder with convertible tailpiece cam covers that opening.
8) Why choose a 7-pin plug instead of a 6-pin for a school or hospital master key system?
Seven chambers give you more room to build a master key hierarchy and tighter key control than a 6-pin plug, which is why the 292K98 is built for commercial mechanical lock systems in offices, schools, healthcare, government buildings, retail, industrial sites, and multi-tenant residential and hospitality. If your facility is standardized on 6-pin, adding 7-pin plugs means a separate keying scheme, not an extension of the existing one.
9) I need a full cylinder, not a plug. What else does ZenSupply carry for commercial openings?
For complete units rather than a rebuild part: the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder, the Schlage 20-021 and 20-022 are 6-pin rim cylinders differing only in tailpiece cam orientation (vertical versus horizontal), and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible cam. On the interchangeable core side, BEST offers the 1C 5-pin core and the 1CDF drill resistant 7-pin brass core in the 150 series.
10) Can a property manager swap the 292K98 in without a locksmith?
Practically, no. Swapping a cylinder plug means pulling the mortise cylinder, disassembling it, and pinning the new plug to the key system, which is bench work with a follower and pin kit. This is a locksmith-level replacement part. A property manager wanting a straight one-for-one change at the door is better served by a complete cylinder or an interchangeable core, such as a BEST 1CB 150 series interchangeable core, which drops in with a control key.
11) What do I use for a knob or lever cylinder rather than a mortise plug?
The Corbin Russwin 292K98 is strictly a mortise cylinder plug. For key-in-knob and key-in-lever openings, the Kaba Ilco 1539 universal key-in-knob/lever cylinder or the 1599 key-in-knob replacement cylinder handle those housings, and the Ilco 1579 is the knob and lever cylinder made for Sargent locks. The Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys.
12) Is there a simpler 5-pin option than the 7-pin 292K98?
The 292K98 is built as a 7-pin plug for added key control in commercial mortise systems. Where a lower pin count suits the opening and a complete cylinder is wanted, the Adams Rite 4036 mortise cylinder is a five-pin Grade 1 unit, and the BEST 1C5 is a standard 5-pin cylinder core. Both are complete cylinders or cores rather than a plug, so the existing Corbin Russwin shell would not be reused.
13) I need to match a storefront aluminum door deadlock. Will the 292K98 work there?
Not directly. The 292K98 plug serves Corbin Russwin 1-3/4 inch mortise cylinder housings. Aluminum storefront deadlocks are usually served by a cylinder pull or a shallow mortise cylinder: the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both made for the MS1847 deadlock/deadlatch, the 4026 five pin cylinder pull is the wood door version for the 5017 deadlock/deadlatch, and the 4036 mortise cylinder works on doors from 1/2 inch minimum thickness.
14) Can I use the 292K98 on a residential handleset or deadbolt?
The 292K98 is specified for commercial mechanical lock systems and fits mortise cylinder housings, so it is not the part for a residential handleset or deadbolt. For those, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
15) Does the 292K98 come in a finish that matches satin chrome hardware?
Yes. The Corbin Russwin 292K98 7-pin mortise cylinder plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to either brass or chrome trim on the opening. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is cataloged in 643E Aged Bronze, which is a darker match than either.
