Corbin Russwin CL3140NT Non-Keyed Exit Latch Cylindrical Lever Lock | Grade 1 Vandal Resistant with T-Zone Construction

Commercial-Grade Exit Latch Security with Patented T-Zone Durability

The Corbin Russwin CL3140NT is a patented Grade 1 non-keyed cylindrical lever lock engineered for demanding commercial exit applications under ANSI function F89 (Exit Latch). Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this leverset features a deadlocking latchbolt operated by the inside lever, while the outside lever remains always locked in a freewheeling position for secure one-way egress. The CL3100 Series T-Zone construction interlocks the aligning and latch tubes to form a rugged torque-resistant “T” in the critical twist area, tested to over 15 million cycles and exceeding ANSI/BHMA A156.2 Series 4000 Grade 1 standards by 15 times. The unit is fire rated and non-handed, retrofitting most standard 161 cylindrical lock door preps for straightforward installation.

Corbin Russwin CL3140NT NZD 626 – Frequently Asked Questions

1) Will the CL3140NT fit a 1-3/8 inch door?
No. The CL3140NT is built for 1-3/4 inch to 2 inch doors only, with a 2-3/4 inch backset. On a 1-3/8 inch interior door you need a lock rated down to that thickness, such as the Falcon K101 Grade 1 cylindrical, which covers 1-3/8 inch to 2-1/4 inch.
2) Can I drop this Corbin Russwin exit latch into an existing cylindrical lock prep?
Yes, it retrofits most standard 161 cylindrical preps with a 2-3/4 inch backset, and it's non-handed, so the same unit works on a left or right swing without conversion. Door thickness has to be in the 1-3/4 to 2 inch range.
3) Can I use the CL3140NT on a fire rated door?
Yes, the CL3140NT is fire rated for use in fire-rated door assemblies. As an exit latch with a deadlocking latchbolt and free inside lever, it also keeps egress unimpeded on the push side.
4) I need a non-keyed lever that lets people through from both sides - is the CL3140NT the right one?
No. Although it's non-keyed, the CL3140NT locks the outside lever permanently, so nobody gets in from the pull side. If you want free operation from both sides, order a passage function instead, for example the Falcon K101 Grade 1 cylindrical passage lever or the Dexter C1000 Grade 1 passage lever. Use the CL3140NT only where the outside face must stay secured.
5) What is the closest Grade 1 non-keyed cylindrical lever alternative to the Corbin Russwin CL3140NT if both levers need to be free?
The CL3140NT is an exit-only lock: the inside lever is always free and the outside lever is always locked and freewheeling. If both sides must always operate, a Grade 1 non-keyed passage lever is the right swap. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors, and the Falcon T101 is a Grade 1 heavy duty passage cylindrical lever in the T Series. Dexter C1000 also offers a Grade 1 clutching passage lever for 1-3/8 inch to 1-3/4 inch doors.
6) I need a keyed lever for the same door instead of an exit-only function - what should I look at?
The CL3140NT is non-keyed, so there is no cylinder to key. For a keyed opening, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever, and the Dexter C1000 is offered as a Grade 1 classroom and Grade 1 classroom security clutching keyed lever. Dexter C1000 also covers Grade 1 asylum function for 1-3/8 inch to 2 inch doors.
7) Is a dummy lever an acceptable substitute for the CL3140NT on the outside of the door?
No. The CL3140NT outside lever is locked but still part of a working cylindrical lock with a deadlocking latchbolt operated from inside, so the door latches. A dummy trim has no latch at all - the BEST 9K 1DT is a Grade 1 single dummy trim, the BEST 7KC 1DT is the Grade 2 medium duty equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy. Those are pull-only trims for inactive leaves, not exit hardware.
8) What should I use instead of the CL3140NT if the door is thinner than 1-3/4 inch?
The CL3140NT covers 1-3/4 inch to 2 inch doors. For thinner leaves, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 asylum function covers 1-3/8 inch to 2 inch, and the Hager 2510 passage lever covers 1-3/8 inch to 2 inch.
9) Is this lock tough enough for a high traffic school or hospital exit door?
It's Grade 1 commercial hardware with T-Zone construction, where the aligning and latch tubes interlock into a torque-resistant T at the point levers get abused. Corbin Russwin cycle tested that to over 15 million cycles, 15 times the ANSI/BHMA A156.2 Series 4000 Grade 1 requirement. The internals are steel, zinc dichromated for corrosion resistance, and a Microshield antimicrobial coating is offered across the finish range for healthcare use.
10) What rose size should I pick if the door has a narrow stile or existing trim to cover?
The standard D rose is 3-1/2 inches in diameter, which is the larger footprint and hides more of an old prep. If trim space is tight, the C and K roses are both 2-3/4 inch diameter, and the E rose is 3-1/8 inch square for a squared-off look. All four work with the same 2-3/4 inch backset chassis.
11) Can I standardize a whole building on the CL3100 Series and still mix functions?
Yes. The CL3140NT exit latch is one function within the CL3100 Series, so the same lever designs (Armstrong, Newport, Princeton), the same four roses and the same 14 finishes carry across the series, letting stairwell exits, offices and classrooms match visually. All CL3100 units in this configuration share the 2-3/4 inch backset and 1-3/4 to 2 inch door range, so preps stay consistent across the openings.
12) Can I use a Grade 2 or Grade 3 lever instead of the CL3140NT on a high-traffic commercial exit door?
The CL3140NT is a Grade 1 commercial lock with T-Zone construction tested past 15 million cycles. Lighter options exist but carry lower grades: the Arrow GL01 and Falcon B101 are Grade 2 passage levers, the Hager 2510 is a Grade 2 passage lever for 1-3/8 inch to 2 inch doors, and the Callan Asheville and Kwikset 200BRNL are Grade 3 passage levers. For a lighter-duty passage opening those work; for a Grade 1 specification they will not meet it.
13) If I want keypad access rather than the exit-only function of the CL3140NT, what lever locks cover that?
The CL3140NT has no keypad or credential - it is a mechanical non-keyed exit latch. For code entry on a lever, the Lockey 1150 heavy duty mechanical keypad lever set fits 1-1/8 inch to 2 inch doors, the Lockey 2835 mechanical pushbutton keyless lever covers 1-3/16 inch to 2 inch and is ADA compliant, and the Delaney LP250 is a Grade 2 electronic keypad leverlock.
14) Does a privacy lever do the same job as the Corbin Russwin CL3140NT?
No. A privacy lever locks from the inside for bath and bedroom use; the CL3140NT keeps the outside lever permanently locked and freewheeling with the inside lever always free, which is one-way egress rather than occupant privacy. Privacy options include the Arrow MK02-TA for 1-3/4 inch to 2 inch doors, the Hager 2540, and the Kwikset 300BRNL Grade 3 privacy lever.
15) Are there other Grade 1 non-keyed levers rated for fire doors besides the CL3140NT?
The CL3140NT is fire rated and Grade 1. Among non-keyed peers, the Falcon K101 is also listed fire rated at Grade 1 with heavy duty classification and non-handed levers. The Design Hardware X75 is a Grade 1 passage lever for 1-3/4 inch doors if a Grade 1 passage function is what the opening needs.
16) Does this Corbin Russwin lever lock count toward LEED credits?
The CL3140NT is made from 68% post-consumer recycled content under LEED MR credit 4, which is why it turns up on institutional and government specs with recycled-content requirements.
