Corbin Russwin 606K77 57A1 626 – Frequently Asked Questions

1) What keyway does the Corbin Russwin 606K77 plug take, and can I pin it to my existing keys?
The plug is machined for the Corbin Russwin 57A1 keyway. It will accept keys cut on a 57A1 blank, so it can be pinned into an existing 57A1 master key system. If your building's Corbin Russwin system runs a different keyway section, this plug will not accept those keys.
2) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 606K77?
The 606K77 is a replacement cylinder plug for 2-1/2 inch Corbin Russwin mortise cylinders, so it only helps if the cylinder shell is staying in the door. For a complete mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder. Both are whole cylinders rather than internal service parts, and neither carries the Corbin Russwin 57A1 keyway, so keys will not interchange with an existing 57A1 system.
3) Is a BEST interchangeable core a substitute for the Corbin Russwin 606K77 plug?
No. The 606K77 is a 7-pin Individual X Class plug that goes inside an existing Corbin Russwin 2-1/2 inch mortise cylinder. A BEST 1CDF is a drill resistant patented interchangeable 7-pin core in the 150 series, and the 1C5 is a standard 5-pin core; those drop into figure-eight interchangeable core housings, not into a conventional mortise cylinder shell. If the housing in the door is a standard Corbin Russwin mortise cylinder, the plug is the service part; if you are converting to removable core, you are changing the cylinder and the keying system, not just the plug.
4) My opening uses a rim exit device, not a mortise lock. What cylinder do I use there?
The Corbin Russwin 606K77 plug is built for 2-1/2 inch mortise cylinders and will not serve a rim 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 6-pin rim cylinder with a horizontal tailpiece cam; the cam orientation is dictated by the exit device you are keying. If you want a removable core rim cylinder, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
5) Does the 606K77 come in anything besides Satin Brass?
Two finishes: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder collar and the rest of the trim on the opening, since the plug face is the visible part once it's assembled.
6) Why choose a 7-pin plug over a 6-pin for a commercial building?
Seven chambers give you more differs and deeper master keying levels, which matters when you're maintaining a large system across many openings. The 606K77 is a 7-pin Individual X Class plug built for commercial use. If your existing Corbin Russwin cylinders are pinned 6-chamber, stay with 6-pin parts rather than mixing, since the key bitting lengths differ.
7) I need a whole mortise cylinder, not a plug. What else does ZenSupply carry?
For a complete mortise cylinder, look at the Adams Rite 4036, a five-pin Grade 1 mortise cylinder that works on doors from 1/2 inch minimum, or the Detex MC65, a 1-1/8 inch six-pin mortise cylinder cut for the Schlage C keyway. Neither is a Corbin Russwin 57A1 part, so if you're keying into an existing Corbin Russwin system the 606K77 plug in your own shell is the way to stay on the same key.
8) Should a facility standardizing on interchangeable core use this plug instead?
No, these are different systems. The 606K77 is a conventional plug that gets pinned into a mortise cylinder shell, which means service requires disassembly. If you want cores a facility manager can swap by hand, look at full-size or small-format interchangeable core products such as the BEST 1CB 150 Series core, the BEST 1CDF drill resistant 7-pin brass core, or the Schlage 20-057 six-pin FSIC rim cylinder with convertible tailpiece cam.
9) What is the difference between the 606K77 plug and a key-in-knob or key-in-lever replacement cylinder?
The 606K77 is a mortise cylinder plug, the pinned core that carries the 57A1 keyway inside a 2-1/2 inch Corbin Russwin mortise cylinder. A key-in-knob or key-in-lever cylinder is a different form factor that seats in the knob or lever itself: the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys. None of those go into a mortise cylinder shell.
10) We have aluminum storefront doors with Adams Rite deadlocks. Will the Corbin Russwin 606K77 work on those?
No. The 606K77 is a service plug for Corbin Russwin 2-1/2 inch mortise cylinders. Adams Rite storefront hardware takes its own cylinder parts: the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch. Match the pull to the deadlock family already in the stile.
11) For a residential-style handleset or deadbolt in one of our units, is the 606K77 the right cylinder part?
The 606K77 is specified for commercial use as a Corbin Russwin mortise cylinder replacement part. Handlesets and residential deadbolts take different retrofit cylinders: 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 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Pick by the lock body brand you are retrofitting.
12) Is this a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. The 606K77 is an authentic Corbin Russwin cylinder component, so it matches the tolerances of the mortise cylinder assembly it goes into. That matters on a factory-keyed system where an aftermarket plug can cause binding or inconsistent key pull.
13) Does the 606K77 plug come with keys or pins?
The 606K77 is sold as the plug itself. Plan on supplying your own top and bottom pins, springs, and 57A1 blanks cut to the bitting you want, which is normal for a locksmith rekeying a system in the shop. If you'd rather receive a keyed unit ready to install, a complete cylinder such as the Adams Rite 4036 is the different route.
14) I need a non-keyed cylinder for the inactive side of a pair. Does the 606K77 cover that?
No. The 606K77 is a pinned 7-pin plug that carries a working 57A1 key. Where you only need the look of a cylinder with no keying, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills the prep without operating anything. Use the 606K77 only where the mortise cylinder actually has to key.
15) Does the finish choice on the 606K77 have an equivalent among other cylinder options?
The Corbin Russwin 606K77 plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to either brass-tone or chrome-tone trim already on the door. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core cylinder is supplied in 643E Aged Bronze with a C keyway, which is a darker tone and a different keyway family, so it is a finish and keying change rather than a match.
