Corbin Russwin CLX3340NT NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CLX3340NT exit latch lever lock actually work from each side of the door?
The CLX3340NT is an exit-only function. The inside lever is always free and retracts a deadlocking latchbolt, so anyone can leave at any time. The outside lever is always locked and freewheels when turned, so there is no key and no way in from the outside. Use it where you need one-way egress, like a stair discharge, service exit, or a back door that should never be an entry point.
2) Will the CLX3340NT fit a 1-3/4 inch commercial door with a 2-3/4 inch backset?
Yes. The standard configuration covers doors 1-3/4 inch to 2 inch thick with a 2-3/4 inch backset, which is the normal commercial hollow metal and wood door setup. It ships with a square corner deadlatch, 2-1/4 x 1-1/8 inch front, cut for the 2-3/4 inch backset.
3) Can I use this exit latch lever lock on a labeled fire door?
Yes, the CLX3340NT is fire rated, and the deadlocking latchbolt plus always-free inside lever is the arrangement a labeled egress door needs. Since there is no key override or hold-open, nothing on the lock defeats the latching requirement.
4) Does the CLX3340NT take a cylinder or a key?
No cylinder and no key. It is a non-keyed lock, so there is nothing to key into a masterkey system and nothing to rekey later. If you need key access from the outside on that opening, an exit latch is the wrong function, look at a storeroom or classroom lock instead.
5) Will this exit latch lock fit a narrow aluminum storefront stile?
Not typically. The CLX3300 Series cylindrical locks need a minimum stile of 4-1/2 inches, which rules out most narrow stile aluminum doors. Narrow stile storefront usually calls for a mortise or rim exit device with lever trim instead.
6) What is the closest Grade 1 non-keyed lever alternative to the Corbin Russwin CLX3340NT if the opening needs to operate from both sides?
The CLX3340NT is an exit-only function - the deadlocking latchbolt retracts by the inside lever while the outside lever stays always locked in a freewheeling position. If the door needs to be opened from both sides, step to a Grade 1 passage lever such as the Falcon K101, a heavy duty Grade 1 non-handed passage cylindrical lock that is fire rated and covers 1-3/8 inch to 2-1/4 inch doors, or the Falcon T101 Grade 1 heavy duty passage lever. Both retract the latch from either side with no locking at all.
7) We only need a lever on the outside with no latch at all - is the CLX3340NT the right part?
No. The CLX3340NT is a functioning cylindrical lockset with a deadlocking latchbolt and an ANSI curved lip strike. For a pull-only application with no latch, use a dummy trim instead: the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim lever, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent. The Accentra 455LN Augusta is another Grade 1 single dummy lever.
8) Do I need to order a left or right hand version of the CLX3340NT?
No handing to specify. The lock is non-handed, so the same part works on a left or right swinging door. That makes it easier to stock one SKU across a building and pull it for whichever opening fails.
9) What lever styles and finishes does the Corbin Russwin CLX3340NT come in?
Three lever designs: Armstrong (AZD), Newport (NZD), and Princeton (PZD). Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 613L dark oxidized satin bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze oil-rubbed, BSP black suede, and WSP white suede powder coat. Matching an existing building standard is usually a matter of picking the same lever design and finish code as the keyed locks already on the floor.
10) Is a Grade 1 exit latch worth it over a Grade 2 lever on a high traffic back door?
On a door that gets kicked, leaned on, and pulled all day, yes. The CLX3340NT is ANSI/BHMA Grade 1, built from steel with a zinc dichromate treatment for corrosion resistance, and the outside lever freewheels when locked so torquing it does not break the chassis. Most commercial passage and entry levers in this class, like the Hager 2510 or the Falcon B101, are Grade 2. If you want Grade 1 but a different function, the Falcon K101 is a Grade 1 fire rated passage lock, though passage leaves both levers free and gives you no security on the outside.
11) My doors are thinner than 1-3/4 inch or thicker than 2 inch. Can I still use the CLX3300 exit latch?
The standard build covers 1-3/4 to 2 inch. The series offers a D138 option for 1-3/8 inch doors and a D214 option for doors over 2 inch up to 2-1/4 inch, plus optional backsets of 2-3/8, 3-3/4, and 5 inches if your bore is not at 2-3/4. Those are order options, so specify them when you place the order rather than trying to adapt in the field.
12) Is a dummy lever a cheaper substitute for an exit latch on a one-way door?
No, and it is a common mistake. A dummy trim such as the BEST 9K 1DT or the Accentra 455LN Augusta is a fixed pull with no latch at all, so the door will not latch or stay shut. The CLX3340NT has a deadlocking latchbolt retracted by the inside lever, which is what keeps the opening secured while still letting people out. Use dummy trim only on an inactive leaf or a door held by other hardware.
13) What latchbolt throw does the CLX3300 Series use, and can I get a longer one?
The standard stainless steel latchbolt has a 1/2 inch throw, which suits a normal frame with a typical reveal. A 3/4 inch deadlocking fire latch is available as an option if your opening has a deeper gap between door and frame or the spec calls for the longer throw on a labeled door.
14) Is there a lighter-duty non-keyed lever to use instead of the CLX3340NT on low-traffic interior doors?
The CLX3340NT is an ANSI/BHMA Grade 1 commercial lockset. Where the traffic does not call for Grade 1, non-keyed Grade 2 levers include the Arrow GL01 passage lock with the Sierra lever, rated for 1-3/4 inch to 2 inch doors, the Falcon B101 Grade 2 non-handed passage lever, the Hager 2510 Grade 2 passage lever covering 1-3/8 inch to 2 inch doors, and the Design Hardware J75 flat-lever passage set for 1-3/4 inch doors. Note these are passage function, free from both sides, not exit-only.
15) For a classroom or institutional door, what Grade 1 lever should we look at instead of the Corbin Russwin CLX3340NT?
The CLX3340NT covers exit-only openings where egress is always free and entry is never permitted. For classroom and institutional control at the same Grade 1 level, the Dexter C1000 Series offers a clutching keyed Classroom lever and a Classroom Security lever, both for 1-3/8 inch to 1-3/4 inch doors, plus a C1000 Asylum (ANSI F87) function for 1-3/8 inch to 2 inch doors where both sides need key operation.
16) Would a keypad lever like the Lockey 2835 work in place of the CLX3340NT?
They solve different problems. The CLX3340NT is a mechanical non-keyed exit latch: free egress inside, no entry from outside at all. The Lockey 2835 is a mechanical pushbutton keyless lever with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the 2835DC adds a double combination - both grant entry to anyone with the code. Choose the keypad units when controlled entry is wanted; choose the CLX3340NT when the outside must stay locked.
17) The door needs a privacy lock for a restroom - can the CLX3340NT be used?
No. The CLX3340NT leaves the inside lever always free and the outside always locked, with no privacy pushbutton for occupant control. For privacy openings, the Arrow MK02-TA is a fire rated privacy knob lock for 1-3/4 inch to 2 inch doors, and the Hager 2540 Withnell privacy lock covers 1-3/8 inch to 2 inch doors.
