Corbin Russwin 606K76 57C1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 606K76 plug work in my existing mortise cylinder housing?
The 606K76 is a 7-pin cylinder plug built for Corbin Russwin mortise cylinder assemblies using the 57C keyway, and it drops into compatible Corbin Russwin mortise cylinder housings. It is a plug only, not a complete cylinder, so the housing, shell, cam and pins have to already be there. If your housing is a 6-pin body or another manufacturer's, this plug is the wrong part.
2) What mortise cylinder lengths does the Corbin Russwin 606K76 come in?
Four mortise lengths are offered: 2-1/4 inch, 2-1/2 inch, 2-3/4 inch and 3 inch. Match the length to the cylinder body already in the lock, which is driven by door thickness and trim projection. Order the wrong length and the cylinder either sits proud of the trim or does not reach the cam.
3) What is the difference between the C1 and C2 keyway options on this Corbin Russwin plug?
C1 and C2 are the two keyway choices offered. Both are Corbin Russwin 57C family keyway sections, and the plug is machined to accept the 57C keyway. Pick whichever section your building's existing keys are cut on, otherwise the key will not enter the plug even though the cylinder fits the lock.
4) Does the 606K76 keep my existing Corbin Russwin master key system working?
Yes. It is an Individual X Class plug, a 7-pin configuration intended to sit inside an existing Corbin Russwin keying hierarchy without breaking it. That makes it the part a locksmith uses to rekey or repair one cylinder in a masterkeyed facility while every other opening keeps working.
5) I need a whole mortise cylinder, not just the plug - what should I order instead of the Corbin Russwin 606K76?
The 606K76 is a cylinder plug, the keyed core barrel that drops into an existing Corbin Russwin mortise cylinder housing, not a complete cylinder. If the housing is gone or damaged, order a complete mortise cylinder instead: the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Note that both of those bring their own keyway, so they will not run on Corbin Russwin 57C keys the way the 606K76 plug does.
6) Our facility wants to move to interchangeable cores instead of rekeying plugs - what replaces the 606K76 approach?
The 606K76 is a fixed plug that is pinned and installed into a Corbin Russwin mortise housing, so rekeying means pulling and repinning the plug. An interchangeable core program instead lets you swap the core with a control key. Comparable cores include the BEST 1C standard 5-pin cylinder core, the BEST 1CB Peaks 150 Series interchangeable core, the BEST 1CDF drill-resistant patented 7-pin interchangeable core in brass, and the Schlage 20-057-C full size interchangeable core in the C keyway with a 643E aged bronze finish. Moving to cores means changing the housings and the key system, not just the plug.
7) We have aluminum storefront doors with Adams Rite deadlocks - is the 606K76 the right cylinder part?
No. The 606K76 is a Corbin Russwin mortise plug on a 57C keyway. For Adams Rite storefront hardware, the 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws are both made for the MS1847 deadlock/deadlatch, and the 4026 five-pin cylinder pull is for the 5017 wood door deadlock/deadlatch. The Adams Rite 4036 Grade 1 mortise cylinder covers a minimum door thickness of 1/2 inch, which suits thin stile aluminum.
8) Can I use this Corbin Russwin plug in a rim cylinder or an exit device?
No. The 606K76 is machined for mortise-style cylinder assemblies. For rim applications, the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal tailpiece cam) are 6-pin rim cylinders, and the BEST 12E Series is a 1-5/32 inch dummy rim cylinder. Rim and mortise cylinders are not interchangeable.
9) What do I need to specify when ordering the Corbin Russwin 606K76 plug?
Three things: mortise length (2-1/4, 2-1/2, 2-3/4 or 3 inch), keyway section (C1 or C2), and finish (606 Satin Brass or 626 Satin Chrome). The model designation reads 606K76 57C1 for the satin brass C1 build.
10) Will a Schlage 20-021 rim cylinder work in place of the Corbin Russwin 606K76?
No. The Schlage 20-021 and 20-022 are rim cylinders, differing from each other by vertical versus horizontal tailpiece cam, and they mount through the door behind rim exit devices. The 606K76 is a plug for a mortise cylinder assembly, which threads into the lock body. The two are different cylinder formats and are not interchangeable.
11) What do I use if the opening is a key-in-lever or deadbolt rather than a mortise lock?
The 606K76 plug is built for mortise cylinder assemblies only. For a key-in-lever opening, 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. For knob, lever, and deadbolt retrofits, Kaba Ilco offers the 1539 key-in-knob/lever universal cylinder, the 1549 key-in-deadbolt cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder.
12) Can I use the 606K76 on residential handlesets and deadbolts?
The 606K76 is specified for commercial mortise cylinder assemblies. For residential handleset and deadbolt retrofits, Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 5-pin lazy motion rim cylinder with Emtek tailpiece, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder as a replacement part.
13) Between the 606K76 plug and a Schlage 20-057 FSIC rim cylinder, which suits a facility standardizing key control?
They standardize in different directions. The 606K76 is a 7-pin X Class plug on the 57C keyway, supporting individual keying hierarchies inside an existing Corbin Russwin mortise system, and it comes in 606 satin brass and 626 satin chrome with mortise lengths of 2-1/4, 2-1/2, 2-3/4 and 3 inch. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with two keys, which standardizes around swappable full size cores on rim-prepped openings.
14) Is the 606K76 suitable for a high-traffic commercial building, or is it residential grade?
Commercial. It is built to Corbin Russwin's commercial tolerances and is the OEM plug used in office buildings, schools, hospitals, government facilities, multi-tenant residential and retail. The 7-pin stack is what gives it the key control a facility standardizing on one keyway needs.
15) Is there a lower pin count option than the 7-pin 606K76 for a less demanding opening?
The 606K76 is a 7-pin plug, chosen where a deeper tumbler stack supports tighter key control. Where fewer pins are acceptable, five- and six-pin cylinders in the comparable set include the Adams Rite 4036 five-pin mortise cylinder, the Detex MC65 six-pin mortise cylinder, and the BEST 1C standard 5-pin core. Dropping pin count changes the key system, so it is a decision made at the masterkey level rather than door by door.
16) We need a non-functioning cylinder for appearance only - does the 606K76 cover that?
No. The 606K76 is a keyed, operating plug for a mortise cylinder assembly. For a blank, non-operating cylinder used to fill a prep or match appearance, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy option in this group, and it is a rim format rather than mortise.
