Corbin Russwin 606K76 27 626 – Frequently Asked Questions

1) Which Corbin Russwin keyways can I get this 7-pin mortise plug in?
Five keyway choices are offered on the 606K76 plug: 27, 67, 77, 97 and 99. Pick the one that matches the keyway already in service on the building so the new plug takes your existing key system. Ordering a keyway that does not match your master key system means the plug will not accept your keys.
2) I manage a building with 6-pin Corbin Russwin cylinders. Can I drop this 7-pin plug in?
This is a 7-pin plug, so it pins and keys as a 7-pin cylinder. It goes into compatible Corbin Russwin mortise cylinder shells and the key must be cut for the 7-pin X Class configuration in the keyway you order. Do not expect an existing 6-pin key to operate it unless your system is already built around this keyway and pin count.
3) What do I have to specify when ordering the 606K76 plug?
Three things: keyway (27, 67, 77, 97 or 99), mortise length (2-1/4, 2-1/2, 2-3/4 or 3 inch), and finish (606 satin brass or 626 satin chrome). Get the keyway from your existing key system records and the length from the cylinder shell in the door.
4) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 606K76 27?
The 606K76 27 is supplied as an individual plug for rekeying and service of Corbin Russwin mortise cylinders, not a full cylinder assembly. When the whole cylinder is being replaced, the Adams Rite 4036 is a complete mortise cylinder with five-pin security, Grade 1, in the 4036 Series with a 1/2 inch minimum door thickness. The Detex MC65 is another complete mortise cylinder, 6-pin with a Schlage C keyway and a 1-1/8 inch body. Note those are different keyway families than the Corbin Russwin X Class keyways, so existing keys will not carry over.
5) We want to rekey doors without pulling cylinders each time - what is an alternative approach to stocking 606K76 plugs?
The 606K76 27 is a 7-pin X Class plug that is swapped into a Corbin Russwin mortise cylinder as a service part. If the goal is rekeying at the door without cylinder disassembly, an interchangeable core system is the other route: the BEST 1CB is a Peaks 150 Series interchangeable core cylinder, the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass 150 Series, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those require IC-prepped housings rather than conventional Corbin Russwin mortise cylinders.
6) Is a rim cylinder like the Schlage 20-021 a substitute for the Corbin Russwin 606K76 plug?
No. The 606K76 27 is a plug for Corbin Russwin mortise cylinders, which thread into a mortise lock body. The Schlage 20-021 and 20-022 are rim cylinders, 6-pin, that mount behind the door face and drive a tailpiece - the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal one. Rim and mortise cylinders use different housings and prep, so they are not interchangeable.
7) Does the plug finish need to match the rest of my door hardware?
Only the exposed face of the plug shows once the cylinder is installed, but it is visible at the keyhole, so matching matters on front entrances and lobby doors. Two finishes are offered: 606 satin brass and 626 satin chrome. Both are available across all five keyways and all four mortise lengths, so you can standardize a building on one finish without giving up length or keyway choice.
8) What is the advantage of rekeying with a new plug instead of replacing the whole mortise cylinder?
Cost and turnaround on a fleet of doors. Swapping the plug changes the keying and the keyway without pulling and replacing the entire cylinder assembly, so a locksmith can bring plugs in the required keyway and length, re-pin at the bench or on site, and leave the existing shells and cams in the lock. For a property manager rekeying a whole floor after a tenant turnover, that is far fewer parts to buy and stock.
9) I need a complete mortise cylinder, not a plug. What else is there?
Go to a full cylinder rather than this plug. The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder cut to the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder for doors 1/2 inch and thicker, typically aluminum storefront. Neither is a Corbin Russwin keyway, so choose them only where you are not tied into an existing Corbin Russwin key system.
10) My exit device takes a rim cylinder. Is this mortise plug the right part?
No. A rim cylinder mounts through the door and drives a tailpiece into the exit device chassis; this Corbin Russwin part is a plug for a threaded mortise cylinder. For rim applications look at the Schlage 20-021 six-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal cam, each supplied with two keys.
11) What do I use for a key-in-lever or key-in-knob lock instead of the Corbin Russwin 606K76 mortise plug?
The 606K76 27 plug only serves mortise cylinder bodies. For keyed lever and knob locks, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T 6-pin G keyway, keyed different with two cut keys. For a keyed deadbolt, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
12) I have an aluminum storefront with an Adams Rite deadlock - will the Corbin Russwin 606K76 work there?
The 606K76 27 is a plug for Corbin Russwin mortise cylinders and does not address Adams Rite storefront prep on its own. For an MS1847 deadlock or deadlatch, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull using through-screws. For a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matched part.
13) Is a BEST 1C5 core the same kind of part as the Corbin Russwin 606K76 plug?
They are both keyed service components but not interchangeable. The 606K76 27 is a 7-pin X Class plug that is fitted inside a Corbin Russwin mortise cylinder housing. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, which drops into a BEST interchangeable core housing as a complete figure-eight core. Pin count, keyway family, and the housing each one seats in are all different.
14) Our 606K76 plugs are ordered in 2-1/4 through 3 inch mortise lengths - is there a peer that covers residential handleset and deadbolt retrofits instead?
The Corbin Russwin 606K76 27 plug is specified by mortise length in 2-1/4, 2-1/2, 2-3/4 and 3 inch, with keyways 27, 67, 77, 97 and 99 in 606 satin brass or 626 satin chrome - all commercial mortise cylinder service. For residential handleset and deadbolt retrofits the Medeco parts apply instead: the 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, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handlesets and deadbolts. The Emtek CY4 cylinder is sold each as an Emtek part.
15) We are standardizing a facility on one keyway - how does the Corbin Russwin 606K76 compare with a keyway-specific core like the Schlage 20-057-C?
The 606K76 27 plug is ordered by Corbin Russwin X Class keyway, with 27, 67, 77, 97 and 99 offered, so the keyway is fixed at the part number and the plug goes into a Corbin Russwin mortise cylinder. The Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, supplied in 643E aged bronze. Standardizing on one of these means standardizing on that manufacturer's key system and the housing type that accepts it.
16) Is this plug suitable for high-traffic commercial doors or is it a residential part?
It is a commercial-grade cylinder part. Corbin Russwin lists the 606K76 27 for commercial mortise cylinder service in offices, schools, healthcare, government buildings, retail, industrial sites and multi-tenant residential properties, which is where 7-pin key control is normally specified.
17) I need a non-keyed filler for an opening that does not need to lock - what is the alternative to a 606K76 plug?
The 606K76 27 is a keyed 7-pin plug intended for rekeying and service of Corbin Russwin mortise cylinders, so it always carries a keyway. Where an opening only needs the cylinder appearance without keyed function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a rim prep without operating a lock.
