Corbin Russwin CLX33905-NZD-626-M92-L4 0BIT 12/24V – Frequently Asked Questions

1) Will the Corbin Russwin CLX33905 electrified lock fit a 1-3/4 inch metal door?

Yes. The CLX33905 cylindrical lock is built for 1-3/4 inch to 2 inch doors as standard, which covers the usual commercial 1-3/4 inch hollow metal or wood door. It needs at least a 4-1/2 inch stile, so it will not go on a narrow stile aluminum door. For thinner or thicker openings the series offers a 1-3/8 inch option (D138) and an over-2-inch up to 2-1/4 inch option (D214), specified when you order. Door prep follows ANSI/SDI A250.14.

2) What happens to a Corbin Russwin CLX33905 fail secure lock when the power goes out?

Fail secure means the outside lever stays locked when power drops. Key access from outside still works through the conventional cylinder, and the inside lever always retracts the latch for free egress. If you need the opening to unlock on a fire alarm or power loss, fail secure is the wrong choice and you want the fail safe version of the same lock instead. Fail secure is the normal pick for a tenant suite, storeroom, or any door that must stay secured when the building loses power.

3) Do I have to order the CLX33905 handed for a left or right hand door?

No handing to specify. The CLX33905 is non-handed, so one part number covers left and right hand openings and a stockroom does not need to carry both. That also means a lock pulled off one door can go back on the opposite hand door without swapping parts.

4) Will the Corbin Russwin CLX33905 latch into the strike already in my frame?

It depends on what is prepped. The CLX33905 ships with a deadlatch on a square corner front, 2-1/4 x 1-1/8 inches, at a 2-3/4 inch backset, and an ANSI curved lip strike with a 1-1/4 inch lip to center in a 4-7/8 x 1-1/4 inch cutout. Standard latchbolt throw is 1/2 inch, with a 3/4 inch deadlocking fire latch available. If your frame is already cut for an ANSI strike, it drops in. If the existing prep is a small round-corner residential strike, plan on a new strike and frame work.

5) My door is bored for a 2-3/8 inch backset. Can I still use the CLX33905?

Not as it ships. The standard build is 2-3/4 inch backset, which is the common commercial bore. A 2-3/8 inch backset is offered as an ordering option on the series, along with 3-3/4 inch and 5 inch for wide stile and special openings, so specify the backset with the order rather than trying to shim a 2-3/4 inch chassis into a 2-3/8 inch prep.

6) What voltage and current does the Corbin Russwin CLX33905 electrified lock need?

The electrified chassis runs on 12VDC or 24VDC, with an operating range of 10.2 to 26.4VDC. Draw is 10mA continuous and 500mA peak at either voltage, so size the power supply for the inrush, not the holding current. Connection is through an ElectroLynx 8-pin molex connector, which mates with a matching electric hinge or power transfer harness instead of hard splicing in the door edge. Rated to operate from -13F to 151F.

7) Can I use a Corbin Russwin CLX33905 on a 3 hour fire rated door?

Yes. The lock is UL/cUL listed for 3 hour fire doors and meets NFPA 80. It also carries ANSI/BHMA A156.2 (2022) Series 4000 Grade 1, UL294 on the electrified units, ADA A117.1 for the lever, and windstorm/hurricane certification. For a fire door, order the 3/4 inch deadlocking fire latch rather than the standard 1/2 inch throw latch.

8) Can I key a Corbin Russwin CLX33905 into my existing master key system?

The standard cylinder is a brass 6-pin L4 keyway shipped 0-bitted, meaning it comes uncut so your locksmith pins it into your existing system. If your facility runs a large format interchangeable core system, order the version prepped less core with the disposable plastic core and drop your own cores in on site. The chassis accepts all cylinder formats from fixed core through interchangeable core, so one lock body covers either approach.

9) The Corbin Russwin CLX33905 needs a 2-3/4 inch backset and a 1-3/4 to 2 inch door. What Grade 1 lever fits a thinner door?

The CLX33905 takes a 2-3/4 inch backset and a 1-3/4 inch to 2 inch door as standard. For a thinner leaf, the Falcon K101 Grade 1 heavy duty passage lever covers 1-3/8 inch to 2-1/4 inch, and the Dexter C1000 Asylum covers 1-3/8 inch to 2 inch, with the Dexter C1000 Classroom, Classroom Security and Entry/Office versions covering 1-3/8 inch to 1-3/4 inch. All of those are keyed or non-keyed mechanical locks rather than electrified, so confirm the door still gets the access control it needs before swapping.

10) What is the closest Grade 1 cylindrical lever lock to the Corbin Russwin CLX33905 if the opening does not need electrification?

For a mechanical-only opening, the Grade 1 cylindrical lever locks in the comparable set are the Dexter C1000 Series, which is offered in Classroom, Classroom Security, Entry/Office and Asylum functions, and the Falcon K101 and T101, both Grade 1 heavy duty cylindrical passage levers. The CLX33905 is an electromechanical cylindrical lock in fail secure configuration with a conventional cylinder and single cylinder keyed function, so it is wired and controlled from an access control system; the Dexter C1000 and Falcon K and T Series units are key and lever operated only. Match the function first: the Dexter C1000 Entry/Office covers an office door, the Classroom Security version covers a room that must lock from inside, and the Falcon K101 or T101 covers a door that only needs to latch.

11) Is a keypad lever lock an alternative to the Corbin Russwin CLX33905 for controlling who gets through a door?

They solve access control differently. The CLX33905 is an electromechanical cylindrical lock, fail secure, wired to a 12VDC or 24VDC supply and released by a signal from an access control system, with a conventional cylinder for key override. A standalone keypad lever such as the Delaney LP250 electronic keypad leverlock, the Emtek Classic Keypad Leverset, or the mechanical pushbutton Lockey 2835 and Lockey 1150 sets carries its credential logic in the lock itself and needs no wiring back to a panel. Choose the CLX33905 when the door has to report to and be released by a central system; choose a keypad set when the door is standalone and a shared code is acceptable.

12) For a classroom that needs a keyed lever rather than a wired one, what replaces the Corbin Russwin CLX33905?

The CLX33905 is a fail secure electromechanical cylindrical lock, meaning the outside lever stays locked when power is removed and the door is released by the access control system, with key override through its conventional cylinder. For a keyed classroom opening with no wiring, the Dexter C1000 Series Grade 1 classroom cylindrical lever with clutching is the closest grade match, and the Dexter C1000 Classroom Security version adds locking of the outside lever by key from inside the room. The Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway and a 2-3/4 inch backset, which matches the CLX33905 backset.

13) What looks like a substitute for the Corbin Russwin CLX33905 but will not do the same job?

Three near-misses come up. A dummy lever such as the BEST 9K 1DT or Accentra 455LN Augusta is Grade 1 like the CLX33905 but is non-keyed fixed trim with no latch at all. A privacy lever such as the Arrow MK02-TA or the Hager 2540 locks from inside with a pushbutton and cannot be keyed or wired for access control, where the CLX33905 is keyed with a single cylinder function. And the Accentra 107S Schlage cylinder adapter kit is a cylinder adapter for Yale hardware, not a lockset. The CLX33905 is an electromechanical cylindrical lockset with a lever, a deadlatch and an ANSI curved lip strike, so a replacement has to be a complete keyed chassis.

14) What is the difference between the request to exit and the plain L4 versions of the Corbin Russwin CLX33905?

Three builds are sold, all fail secure with the Newport (NZD) lever in 626 satin chrome. Two carry request to exit: one prepped for a large format interchangeable core, 6-pin, supplied less core with a disposable plastic core, and one with a conventional L4 6-pin 0-bitted cylinder. The third is the L4 6-pin 0-bit without the REX switch. Take a REX version when the lock has to signal the access control panel that someone left through the door, so the alarm does not trip on legitimate egress. Skip it if the opening is just electrically controlled entry with no monitoring.

15) Is a Grade 1 cylindrical lever lock worth it over Grade 2 for a school or hospital corridor?

For high cycle openings, yes. The CLX33905 tests above 20 million cycles, holds past 3,100 in-lb of abusive locked lever torque (2.6 times the ANSI requirement) and 1,600 lbs of offset lever pull, and uses a freewheeling Lever Release design so a lever hung on or kicked spins instead of breaking the chassis. Grade 2 lever locks like the Falcon B101 or Hager 2510 are medium duty and fine for offices and closets where nobody is abusing the trim. Put the Grade 1 on the classroom, patient room, and public restroom doors.

16) I need a keypad lever lock instead of a wired electric lock. What are my options?

A wired lock like the CLX33905 needs a power supply, transfer hinge, and a panel behind it. If you only want code entry on a single door with no wiring, look at standalone keypad levers instead: the Lockey 1150 heavy duty mechanical keypad lever with double combination fits 1-1/8 to 2 inch doors, the Lockey 2835 mechanical pushbutton keyless lever fits 1-3/16 to 2 inch doors, or the Delaney LP250 electronic keypad leverlock in Grade 2. Those trade the audit trail and central control of a wired system for a far simpler install.

17) Can I match the CLX33905 lever and finish across the rest of the doors on the floor?

The lock is sold with the NZD Newport lever on a D rose in 626 satin chrome, which is the standard commercial finish and will visually match most existing 626 lever trim in a building. The CLX3300 series carries 27 mechanical and 2 electrified functions, so the non-electric passage, privacy, classroom, and storeroom doors around it can be ordered in the same lever and finish and only the access controlled openings carry the electrified chassis.

18) For the inactive leaf or a pull-only door next to a Corbin Russwin CLX33905 opening, what lever matches without the lock?

A dummy trim gives the same lever presence with no latch or chassis. The BEST 9K Series 1DT single dummy trim is a Grade 1 non-keyed heavy duty cylindrical lever, the closest grade match to the Grade 1 CLX33905; the BEST 7KC Series 1DT single dummy is Grade 2 medium duty, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever. Note that a dummy is fixed trim only: it does not latch, so it belongs on a leaf held by flush bolts or a magnetic catch, never on the active leaf the CLX33905 would secure.

19) What should be used on the lower-traffic doors in a building where the Corbin Russwin CLX33905 covers the controlled openings?

The CLX33905 is a Grade 1 commercial electromechanical lock; office, corridor and storage doors behind it rarely need that. For a keyed storeroom door, the Hager 2580 and the Cal-Royal AG05 are both Grade 2 storeroom levers with the AG05 carrying a deadlocking latchbolt. For an office door, the Hager 2525 Grade 2 entry lever or the Falcon B511CP6D Grade 2 entry/office lever suits. For a corridor or closet door that only latches, the Falcon B101, Hager 2510, Design Hardware J75 and Accentra 5301LN Augusta are Grade 2 passage levers, and the Design Hardware X75 is a Grade 1 passage lever if the door sees heavy use.

20) Can a residential-grade lever be used in place of the Corbin Russwin CLX33905?

No. The CLX33905 is a Grade 1 commercial electromechanical cylindrical lock listed by UL and cUL for 3-hour fire doors and built to ANSI/BHMA A156.2 Series 4000. Grade 3 levers such as the Kwikset 200BRNL Breton passage, the Kwikset 300BRNL Breton privacy, the Cal-Royal AUS00 entrance/office and the Callan Artino and Bennett entrance sets, along with the unrated Baldwin Estate 5103 and Emtek and Deltana decorative levers, are built for interior and residential openings. None of them carries the electrified operation, ANSI Grade 1 rating or fire listing that a controlled commercial opening is specified for.

21) Is a lever required, or will a knob lock work on the same opening as a Corbin Russwin CLX33905?

The CLX33905 uses a lever, which is what ADA A117.1 calls for on doors requiring accessible operation, and the lock is ADA compliant per its listed certifications. Knob-operated cylindrical locks in the same size class include the Arrow HK11-BB turn-pushbutton entrance lock with a ball knob and conventional cylinder, the Arrow MK33-BD-CS asylum lock with a ball knob and Schlage C keyway, and the Arrow MK02-TA privacy lock with a Tudor knob. A knob is a fit for a utility or mechanical room outside the accessible route; on an accessible-route door the lever trim is the one to keep.

22) What handles a patient room or utility door that the Corbin Russwin CLX33905 is not configured for?

An asylum or institutional function locks or unlocks from either side by key with no free-turning inside lever, which is a different job from the fail secure electromechanical operation of the CLX33905. The Dexter C1000 Series Asylum, function F87, is Grade 1 and fits doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and a conventional cylinder in Schlage C keyway. Both are mechanical, so a door that must also release from an access control system stays with the CLX33905.

23) Does the CLX33905 need adjustment when the door thickness varies across a building?

The series uses a patented adjustable push/turn button so the same lock covers the 1-3/4 to 2 inch range without ordering a different part for each thickness. That matters on a retrofit where the doors on a floor are not all the same. Outside that range you specify the D138 or D214 option at the time of order, not on site.
