Corbin Russwin CL3340NT NZD 626 – Frequently Asked Questions

1) What does the Corbin Russwin CL3340NT exit latch function actually do on the door?
The CL3340NT is exit-only. The inside lever always retracts the deadlocking latchbolt so people can always get out, and the outside lever is permanently locked. There is no key and no cylinder on the outside, so there is no way to enter through the door from the exterior side. Use it on stair discharge doors, back-of-house exits, and any opening where you want free egress and zero credential-based entry.
2) Will the CL3340NT fit a 1-3/4 inch commercial door with a 2-3/4 inch backset?
Yes, that is the standard configuration. The CL3340NT covers doors 1-3/4 inches through 2 inches thick and ships with a 2-3/4 inch backset, which is the normal commercial bore layout. For thicker doors, Corbin Russwin offers an over-2-inch option up to 2-1/4 inches, and 3-3/4 inch and 5 inch backsets are available for wide-stile or flush-pull situations.
3) Do I have to specify a hand when ordering the CL3340NT?
No. The CL3340NT is non-handed, so one part number works on left or right hand doors, inswing or outswing. That is useful if you are stocking spares for a building with mixed openings. The only handed item in the CL3300 family is the FZD trim.
4) Can the CL3340NT go on a fire rated door?
Yes. The CL3340NT is fire rated and the CL3300 Series carries UL-cUL listing plus California State Fire Marshal listing. The standard latch has a 1/2 inch throw; an optional 3/4 inch fire latch is available, which is what many fire door assemblies with larger gaps call for. Confirm the throw required by your door and frame manufacturer's listing before you order.
5) I need a non-keyed Grade 1 lever but people have to get in from both sides. Is the CL3340NT the wrong lock?
Yes, it is the wrong function for that. The CL3340NT locks the outside lever permanently, so nobody enters through it. For free operation from both sides on a Grade 1 chassis, look at a passage function lever such as the Falcon K101 (Grade 1, fire rated, 1-3/8 to 2-1/4 inch doors), the Falcon T101 Grade 1 heavy duty passage lever, or the Dexter C1000 Series passage lever. If the opening only needs trim with no latch at all, the BEST 9K Series 1DT single dummy is the Grade 1 option.
6) What is the closest Grade 1 non-keyed cylindrical lever lock to the Corbin Russwin CL3340NT if I need free operation from both sides instead of exit-only?
The CL3340NT is a Grade 1 non-keyed exit latch: the inside lever always retracts the deadlocking latchbolt while the outside lever is always locked and freewheels. If both levers need to operate the latch, look at a Grade 1 passage function instead. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock, fire rated, with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range. The Falcon T101 is also a Grade 1 heavy duty passage cylindrical lever lock in the T Series, and the Dexter C1000 passage is a Grade 1 clutching non-keyed passage lever for 1-3/8 inch to 1-3/4 inch doors. Those give free entry from the corridor side, which the CL3340NT deliberately does not.
7) I need a keyed lock for the same opening rather than the Corbin Russwin CL3340NT exit latch - what should I look at?
The CL3340NT is non-keyed, so there is no outside key access at all. For a keyed opening, the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. For a keyed classroom opening, the Dexter C1000 classroom is Grade 1 clutching and keyed for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway on a 2-3/4 inch backset like the CL3340NT.
8) My door is 1-3/8 inches thick - will the Corbin Russwin CL3340NT fit, and what fits if not?
The CL3340NT covers 1-3/4 inch to 2 inch doors as standard, so a 1-3/8 inch leaf falls below its range. Options that reach down to 1-3/8 inch include the Falcon K101, a Grade 1 heavy duty fire rated passage lever for 1-3/8 inch to 2-1/4 inch doors, the Dexter C1000 asylum function at 1-3/8 inch to 2 inch, and the Hager 2510 passage and Hager 2525 entry at 1-3/8 inch to 2 inch. Confirm the function you need separately, since none of those is an exit latch.
9) Should I order the square corner or rounded corner latch front for the CL3340NT?
Match whatever is already routed into the door edge. The CL3340NT ships standard with the 586F17 square corner deadlatch, 2-1/4 by 1-1/8 inch face, 2-3/4 inch backset. If your existing mortise for the latch face has radiused corners, order the 596F67 rounded corner deadlatch in the same size and backset instead of chiseling the pocket square.
10) What lever styles and finishes does the CL3340NT come in?
Three cast lever designs are offered: Armstrong (AZD), Newport (NZD) and Princeton (PZD). Finishes run from bright and satin brass (605, 606) and bronze (611, 612, 613, 613E, 613L, 722) through bright and satin nickel (618, 619) and bright and satin chrome (625, 626), plus Black Suede and White Suede powder coat. Satin chrome 626 is the usual commercial default if you are matching existing openings.
11) Is the CL3340NT tough enough for a high-abuse exit door where people hang on the outside lever?
That is the case it was built for. It is a Grade 1 extra heavy-duty cylindrical lockset to ANSI/BHMA A156.2 Series 4000, with a steel chassis that is zinc dichromated for corrosion resistance. The outside lever uses the Lever Release design, so when locked it freewheels rather than transmitting force into the chassis, and independent return springs keep the levers from sagging over time. Anti-rotational through-bolts at 6 and 12 o'clock keep the trim from spinning on the door.
12) Can the CL3340NT be electrified so access control can release the outside lever?
Not this model as built, because the CL3340NT is a mechanical non-keyed exit latch. The electrified version within the CL3300 platform is the CL33900 Series, offered fail safe or fail secure at 12 or 24VAC/VDC, drawing 250mA at 12V and 150mA at 24V on a continuous duty solenoid. All electrified units use the ElectroLynx 8-pin connector, so they plug into a matching electric hinge or power transfer without field-splicing.
13) If I am standardizing a school or hospital on the CL3300 platform, what other functions share the same chassis?
The CL3300 Series is one cylindrical platform, so the CL3340NT exit latch shares its chassis, trim and installation with the rest of the family, including the CL3352 classroom intruder function, a double-cylinder lockset that always allows free egress. The chassis accepts 6 or 7-pin conventional cylinders and all keying levels, so keyed functions in the series drop into an existing masterkey system. MicroShield antimicrobial coating is available on the series with option code C, which healthcare specs often call for.
14) Is a dummy lever an acceptable substitute for the Corbin Russwin CL3340NT on the pull side of an exit door?
No. The CL3340NT has a working latchbolt that the inside lever retracts, so it actually latches the door. A dummy trim has no latch and no chassis - the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim lever, the BEST 7KC 1DT is the Grade 2 medium duty equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy in the 5400 Series. Those are surface trim for an inactive leaf or a door held by other hardware. If the leaf needs to latch and be released from inside, you need the CL3340NT function, not a dummy.
15) We only need a light-duty non-keyed lever on an interior office door - is there a simpler option than the Corbin Russwin CL3340NT?
The CL3340NT is a Grade 1 extra heavy-duty commercial exit latch built for high-traffic openings. For an interior door that just needs a latch and no locking, Grade 2 non-keyed levers cover it: the Arrow GL01 is a Grade 2 passage cylindrical lock with a Sierra lever for 1-3/4 inch to 2 inch doors, the Falcon B101 is a Grade 2 medium duty non-handed passage lever, the Hager 2510 is Grade 2 passage for 1-3/8 inch to 2 inch doors, and the Design Hardware J75 is a Grade 2 passage lever for 1-3/4 inch doors. Note these operate from both sides, unlike the CL3340NT's locked outside lever.
16) Can I use a Kwikset or Callan lever in place of the Corbin Russwin CL3340NT on a commercial corridor door?
They are different classes of hardware. The CL3340NT is a Grade 1 commercial cylindrical lockset. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy are Grade 3 for 1-3/8 to 1-3/4 inch doors, and the Callan Asheville passage and Artino entrance leversets are Grade 3 as well. Grade 3 levers are residential-duty and none of them provide the exit-only function where the outside lever is permanently locked. For a commercial opening that has to hold up to traffic, stay in Grade 1 - the Falcon K101 and Dexter C1000 passage are Grade 1 non-keyed alternatives if the function can change.
17) The opening needs code entry rather than a key - what replaces the Corbin Russwin CL3340NT?
The CL3340NT has no outside credential of any kind; the outside lever is always locked and freewheels. If staff need to get in from the outside with a code, mechanical and electronic keypad leversets do that job: the Lockey 2835 and 2835DC are mechanical pushbutton keyless lever locks for 1-3/16 inch to 2 inch doors, the Lockey 1150 and 1150S are heavy duty mechanical keypad lever sets for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. The tradeoff is that the CL3340NT is Grade 1 and fire rated.
18) For a utility or institutional room where both levers must be rigid or key-operated, is the Corbin Russwin CL3340NT the right choice?
Not usually. The CL3340NT leaves the inside lever always free for egress and the outside lever permanently locked and freewheeling. Asylum and institutional functions control both sides instead: the Dexter C1000 asylum is a Grade 1 cylindrical lock in the F87 asylum function for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum cylindrical lock with a ball knob and a conventional Schlage C keyway cylinder. Choose the CL3340NT where free egress from inside is required and the asylum functions where it is not.
19) We want a decorative lever on a residential-style interior door - how does that compare to the Corbin Russwin CL3340NT?
The CL3340NT is a commercial Grade 1 cylindrical lockset in finishes like 626 satin chrome, 613 oil-rubbed satin bronze, and 619 satin nickel with Armstrong, Newport, and Princeton levers - functional rather than decorative. For residential interior doors, the Baldwin Estate 5103 comes in passage, privacy, and left- or right-hand half dummy versions with the 5048 rose, and Emtek offers Arts and Crafts, Hammered, and Cortina dummy lever pairs. Those are trim-led products and none carries the exit latch function.
