Corbin Russwin 596K29 57D1 626 – Frequently Asked Questions

1) Which Corbin Russwin locks does the 596K29 cylinder plug fit?
The 596K29 plug is made for Corbin Russwin CL3300, CL3500, CL3600, CL3700 and CL3800 series mortise lock cylinders. It is a genuine Corbin Russwin cylinder part built to factory specification, so it drops into those cylinders without modification. If your lock is a different Corbin Russwin family, or another brand entirely, this is not the plug for it.
2) Is the 596K29 a complete cylinder or just the plug?
Just the plug. It is sold as an individual plug unit, which lets a locksmith replace the core of the cylinder without buying a whole new cylinder assembly. You supply the pinning, springs and key blanks. If you need a full cylinder rather than a service part, look at a complete mortise cylinder instead, such as the Adams Rite 4036 Grade 1 mortise cylinder.
3) What keyway options are there on the 596K29 plug, and what keys will work?
Two keyway choices are offered, D1 and D2, within the Corbin Russwin 57D key section. The 57D keyway accepts standard Corbin Russwin 57D key blanks and bitting. Pick the same D1 or D2 designation your existing system uses, because the two are not interchangeable keys.
4) I manage a building with Schlage and BEST cylinders too. Will this Corbin Russwin plug work in those?
No. The 596K29 is a Corbin Russwin plug in the 57D key section and only fits Corbin Russwin CL3300 to CL3800 cylinders. For Schlage openings you want a Schlage cylinder such as the 20-021 rim cylinder or the 20-057 full size interchangeable core, and for BEST small format interchangeable core doors a BEST 1C series core. Mixing key sections across brands is not possible at the plug level.
5) If I need a complete mortise cylinder instead of just a plug, what should I order?
The Corbin Russwin 596K29 is an individual X Class cylinder plug, a replacement core component for CL3300, CL3500, CL3600, CL3700 and CL3800 series cylinders rather than a finished cylinder assembly. If the opening needs a whole mortise cylinder, the Adams Rite 4036 is a mortise cylinder with five-pin security in the 4036 Series, and the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder with a Schlage C keyway. Those two are complete cylinders you thread into the lock case; the 596K29 is the plug that goes inside an existing Corbin Russwin cylinder housing.
6) Can I use a BEST interchangeable core in place of the 596K29 plug?
No. The 596K29 is a 5 and 6-pin Individual X Class plug cut for the Corbin Russwin 57D keyway and built to drop into CL3300 through CL3800 series cylinders. BEST interchangeable cores such as the 1C Series standard 5-pin core, the Peaks 1CB 150 Series core, or the 1CDF drill resistant 7-pin 150 Series core are figure-eight interchangeable cores that require an IC-prepped housing. They are a different cylinder architecture, so a BEST core would mean changing the housing, not just the plug.
7) What is the equivalent replacement plug for a Sargent or Schlage key-in-lever lock?
The 596K29 plug is specific to Corbin Russwin CL3300, CL3500, CL3600, CL3700 and CL3800 cylinders with the 57D keyway, so it will not serve another manufacturer's lock. For Sargent knob and lever locks, the Kaba Ilco 1579 Series cylinder is built for Sargent. For a Falcon key-in-lever, the Falcon A23161-05 G is a 6-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys. The Kaba Ilco 1599 is a key-in-knob replacement cylinder and the 1539 Series is a universal key-in-knob/lever cylinder.
8) What finishes does the 596K29 plug come in, and does the finish matter if the plug is hidden?
Two finishes: 606 satin brass and 626 satin chrome, and both are available in either the D1 or D2 keyway. The plug face is visible at the keyhole, so match it to the cylinder ring and lock trim already on the door, 626 satin chrome with chrome or brushed nickel hardware, 606 satin brass with brass.
9) Can I use the 596K29 plug to rekey doors into an existing Corbin Russwin master key system?
Yes, that is its purpose. Individual X Class pinning in 5 or 6 pins lets the plug be keyed into an existing Corbin Russwin master key system on CL3300 through CL3800 mortise locks, which is why facilities with campus-wide masterkeying buy it as a service part rather than replacing cylinders.
10) Do keys come with the Corbin Russwin 596K29 plug?
No keys are included. The 596K29 ships as a bare plug for a locksmith to pin and key to your system using 57D blanks. If you want a cylinder that arrives already keyed with cut keys, a factory keyed unit such as the Falcon A23161-05 G, which comes keyed different with two cut keys, is that kind of product instead.
11) I have an exit device that needs a rim cylinder, not a mortise plug. What are my options?
The Corbin Russwin 596K29 is a mortise cylinder plug for CL series mortise locks and does not fit rim device prep. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. If the facility is standardized on full size interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Choose vertical or horizontal cam to match what the device manufacturer calls for.
12) Does the 596K29 work on an aluminum storefront narrow stile door?
The 596K29 is a plug for Corbin Russwin CL3300 through CL3800 mortise lock cylinders, which is not the hardware set used on narrow stile aluminum entrances. For those openings, Adams Rite offers the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws, both intended for use with the MS1847 deadlock/deadlatch. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock/deadlatch.
13) What do I use for a residential deadbolt or handleset instead of the 596K29?
The 596K29 is a commercial part for Corbin Russwin CL series mortise cylinders. For deadbolts and handlesets, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and Emtek's own CY4 cylinder is sold individually.
14) We are standardizing a facility on interchangeable core. How does that change what I order for the CL series doors?
The 596K29 keeps you in conventional Corbin Russwin cylinders: it is an individual X Class plug in the 57D keyway that rekeys the existing CL3300 through CL3800 cylinders in place, and it comes in 606 satin brass and 626 satin chrome with D1 and D2 keyway variations. Standardizing on full size interchangeable core instead means IC-prepped hardware and cores such as the Schlage 20-057-C full size interchangeable core cylinder in C keyway and 643E aged bronze. The IC route lets staff swap cores by hand; the plug route keeps the existing Corbin Russwin cylinders and keyway system intact.
15) Is the 596K29 plug suitable for a school or hospital, or is it residential hardware?
It is commercial hardware, catalogued for commercial mortise lock service, and it is used in schools, hospitals, government buildings and multi-tenant properties running Corbin Russwin CL series mortise locks. For light residential key-in-knob or deadbolt work a universal replacement cylinder like the Kaba Ilco 1539 or 1599 is the more typical part.
16) Is there a cylinder that just fills the hole without keying, for a door that does not need to lock?
The 596K29 is a keyed plug in the 57D keyway and is always part of a working cylinder. If an opening only needs the appearance of a cylinder, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is a non-functioning unit made for that purpose. Use the 596K29 where the CL series lock has to key into the master key system, and the dummy where it does not.
