Corbin Russwin CR2000-044-6-L4-626 – Frequently Asked Questions

1) Can I use a Corbin Russwin 044 key-in-lever cylinder in an exit device or a rim application?
No. The 044 is a key-in-lever cylinder, shaped and tailed for the lever of a CLX3300 or CL3400 cylindrical lockset. A rim device needs a rim cylinder with a tailpiece, such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam, both 6-pin and supplied with 2 keys. For a mortise lock body you need a threaded mortise cylinder, for example the Adams Rite 4036 five-pin Grade 1 mortise cylinder. The three formats are not interchangeable.
2) Can I get the Corbin Russwin 044 cylinder keyed into our existing building master key system?
That is what it is for. The 044 key-in-lever cylinder is offered across 84 Corbin Russwin keyways, including the 27, 57, 59, 67, 77, N-series, H-series, L-series, D1/D2, G, AR, BL and BR sections, plus 252, 60, 70, 97, 981, 982 and 99. Order the keyway your existing system is built in and the cylinder can be pinned into that master key hierarchy. Pin count is a separate choice: 6 pin or 7 pin. Match both the keyway and the pin count to the rest of your system, because a 7 pin system will not accept a 6 pin cylinder without rekeying.
3) Will swapping the cylinder in a CLX3300 lever lock keep its Grade 1 and fire rating?
The CLX3300 and CL3400 chassis these cylinders serve are ANSI/BHMA A156.2 (2022) Series 4000 Grade 1 and carry a UL/cUL 3-hour rating along with NFPA 80 and ADA A117.1 compliance. Using the manufacturer's own 2000 Series conventional cylinder is how you keep that lockset as specified. Substituting an off-brand cylinder into a fire door lock is what puts the listing in question during inspection.
4) Can a Kaba Ilco 1539 universal cylinder replace a Corbin Russwin 2000-044?
The Kaba Ilco 1539 Series is a key-in-knob / lever universal cylinder, so it is aimed at covering a range of knob and lever chassis rather than one manufacturer's line. The 2000-044 is the conventional key-in-lever cylinder built specifically for Corbin Russwin CLX3300 and CL3400 Series locksets and comes in Corbin Russwin keyways such as L4, N-series and 57-series, in 6-pin or 7-pin. If the opening has to stay on an existing Corbin Russwin master key system, the 2000-044 keeps that system intact; the Ilco 1539 is the choice when the goal is a general-purpose aftermarket cylinder rather than staying native to the Corbin Russwin keyway family.
5) What cylinder do I use if the opening is a rim exit device instead of a lever lockset?
A key-in-lever cylinder will not serve a rim device. For a rim application, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam - the cam orientation is picked to match the device. The Corbin Russwin 2000-044 is a conventional key-in-lever cylinder for CLX3300 and CL3400 Series cylindrical lever locksets, so it belongs in the lever, not the exit device.
6) What is the difference between the Corbin Russwin 2000-044 and a BEST interchangeable core?
They are two different keying architectures. The 2000-044 is a conventional key-in-lever cylinder, so the cylinder itself is pinned and stays in the lever. BEST interchangeable core products such as the 1CB 150 Series core and the 1CDF drill resistant patented 7-pin brass 150 Series core are removable cores that pull with a control key, which is what lets a facility rekey without disassembling hardware. A conventional cylinder like the 2000-044 has to be pulled and repinned instead. If a facility is standardizing on removable-core rekeying, the BEST cores fit that program; if the CLX3300 and CL3400 levers are already keyed conventionally, the 2000-044 keeps the opening on the existing system.
7) Do Corbin Russwin 044 replacement cylinders come keyed, or do I have to pin them myself?
The 2000 Series key-in-lever cylinder is brass with a 6-pin L4 keyway and is supplied 0-bitted as standard, meaning a locksmith pins and cuts it to your system. Two keys come with the cylinder. Other keyways are available to order if your system is not L4, and 7-pin is offered alongside 6-pin.
8) I am replacing a cylinder in a Corbin Russwin lever lock on a 1-3/8 inch door. Does door thickness change the cylinder I order?
No. Door thickness is handled by the lockset, not the cylinder. The CLX3300 and CL3400 chassis is set up for 1-3/4 inch to 2 inch (44 to 51mm) doors as standard, with a D138 option for 1-3/8 inch and D214 for over 2 inch up to 2-1/4 inch, and it uses an adjustable push/turn button to take up the difference. The 2000-044 cylinder itself is specified by keyway, pin count and finish only.
9) Is there a universal key-in-lever cylinder that will work instead of the Corbin Russwin 2000-044?
The 2000-044 is the factory part matched to CLX3300 and CL3400 chassis, and staying with it is the clean route if you are keying into an existing Corbin Russwin system. Aftermarket key-in-knob and lever cylinders do exist: the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, and the Ilco 1579 is the knob and lever cylinder cut for Sargent locks. If your job is Falcon rather than Corbin Russwin, the Falcon A23161-05 G is a 6-pin G keyway key-in-lever cylinder supplied keyed different with 2 cut keys. Check the tailpiece and cam against your chassis before going aftermarket, because that is where these swaps fail.
10) We want to move our building to interchangeable cores. Is the Corbin Russwin 044 the right cylinder for that?
No, and you do not need to change locks to do it. The 044 is a conventional fixed cylinder; the CLX3300 lock chassis supports all cylinder formats from fixed core through interchangeable core, so the same locksets accept an IC housing and core. If you are standardizing a facility on small format IC, look at cores such as the BEST 1C Series standard 5-pin core or the 1CDF drill resistant patented 7-pin core in the 150 Series. Use the 044 where you are staying conventional and simply replacing a worn or compromised cylinder.
11) Is a mortise cylinder the same as the Corbin Russwin 2000-044?
No. A mortise cylinder threads into a mortise lock body - the Adams Rite 4036 is a Grade 1 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 in the Schlage C keyway. The 2000-044 is a conventional key-in-lever cylinder that seats in the lever of a Corbin Russwin CLX3300 or CL3400 cylindrical lockset and is non-handed. The two prep types are not interchangeable, so confirm whether the door carries a cylindrical lever lock or a mortise lock body before ordering.
12) What cylinder goes in a deadbolt rather than a Corbin Russwin CLX3300 lever?
For a deadbolt, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the Kaba Ilco 1599 is a key-in-knob replacement cylinder, both catalogued for deadbolt function. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. The Corbin Russwin 2000-044 is the key-in-lever cylinder for CLX3300 and CL3400 Series locksets, so it goes in the lever and does not serve a separate deadbolt on the same door.
13) What should I order if I need a full size interchangeable core cylinder instead of a conventional one?
For a full size interchangeable core program, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and 2 keys, and the 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E aged bronze finish. The Corbin Russwin 2000-044 is a conventional key-in-lever cylinder for CLX3300 and CL3400 Series locksets, offered in 6-pin and 7-pin and in 606 satin brass or 626 satin chrome. Decide by the keying program the building runs: FSIC lets the core be swapped with a control key, while the conventional 2000-044 is pinned to the Corbin Russwin keyway family the site already uses.
14) Is the Corbin Russwin 2000-044 cylinder rated for commercial traffic like a school or hospital corridor?
It is a commercial cylinder, and the CLX3300 and CL3400 locksets it goes into are tested to 20 million cycles under UL verification and rated Grade 1 to ANSI/BHMA A156.2. Those chassis are also windstorm and hurricane certified. That combination is why the family shows up in educational, healthcare, government and multi-tenant residential work.
15) Is the BEST 12E dummy rim cylinder an alternative to the Corbin Russwin 2000-044?
No - the BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter, meaning it fills the opening for appearance and does not key or operate a lock. The Corbin Russwin 2000-044 is a working conventional key-in-lever cylinder for CLX3300 and CL3400 Series locksets, supplied with 2 keys and available in 6-pin or 7-pin across the Corbin Russwin keyway range. Order the dummy only where a non-functioning cylinder face is wanted; order the 2000-044 where the lever has to be keyed.
16) Can I use a Medeco or Emtek retrofit cylinder on a commercial CLX3300 lever?
Those are built for other hardware. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Emtek CY4 is a cylinder sold each for Emtek parts. The Corbin Russwin 2000-044 is a commercial key-in-lever cylinder for CLX3300 and CL3400 Series locksets in 6-pin or 7-pin, which is the one that seats in that lever.
17) I need a 5-pin core - does the Corbin Russwin 2000-044 come that way?
The 2000-044 is offered in 6-pin and 7-pin. Where a 5-pin core is what the system runs, the BEST 1C Series standard 5-pin cylinder core is the 5-pin option among comparable cores, and the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin unit for mortise prep. Pin count has to match the master key system the building keys to, so confirm the system chart before choosing between the 6-pin and 7-pin 2000-044.
