Corbin Russwin CLX3340 NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CLX3340 patio/privacy function actually work on the door?
The CLX3340 is ANSI function F77. The outside lever locks with a push button, and once locked that outside lever freewheels so pushing or hanging on it doesn't damage the chassis. The inside lever is always free, so anyone inside can leave without unlocking anything. There is no key and no outside override, which is why it shouldn't go on a room with no second way in.
2) Will the CLX3340 fit a 1-3/8 inch door or only a standard 1-3/4 inch commercial door?
Standard build covers 1-3/4 inch to 2 inch doors. For a thinner 1-3/8 inch door you have to order the D138 option, and for doors over 2 inch up to 2-1/4 inch it's the D214 option. The push/turn button is adjustable within the range, so one lock covers 1-3/4 through 2 inch without extra parts.
3) What backset does this Corbin Russwin lever lock need, and can I get it for a 2-3/8 inch bore?
It ships 2-3/4 inch backset as standard, which is the usual commercial layout. Optional backsets are 2-3/8 inch, 3-3/4 inch and 5 inch, so an existing door with a 2-3/8 inch prep or a deep stile can still be covered. Minimum stile width is 4-1/2 inch, so it is not a narrow stile aluminum door lock.
4) Can I use this privacy lever on a fire rated door?
Yes. The CLX3340 is fire rated, with UL/cUL 3-hour listing and NFPA 80 compliance stated for the CLX3300 Series, and the door prep follows ANSI/SDI A250.14. On a fire door you want the 3/4 inch deadlocking fire latch option rather than the standard 1/2 inch throw springlatch.
5) The door has no second exit - what should I use instead of the CLX3340?
The CLX3340 function note states it should not be used in rooms that have no other entrance, since the outside lever locks by push button. For a door that must always be operable from both sides, a passage lockset is the correct swap: the Falcon K101 is a Grade 1 non-keyed passage cylindrical lock, fire rated, for 1-3/8 inch to 2-1/4 inch doors, 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.
6) I need privacy function on a 1-3/8 inch door - what works instead of the CLX3340?
The CLX3340 is built for 1-3/4 inch to 2 inch doors as standard. For a thinner door, the Kwikset 300BRNL RDT Breton privacy leverset is a Grade 3 privacy/bed/bath lever covering 1-3/8 inch to 1-3/4 inch doors, and the Hager 2540 Grade 2 privacy lock covers 1-3/8 inch to 2 inch. Both are lighter-duty than the Grade 1 CLX3340.
7) Is the CLX3340 handed? I have doors swinging both ways in the same corridor.
Non-handed. One part number covers left and right hand doors, so you can stock a single lever lock for a whole floor of openings regardless of swing.
8) Is a Grade 1 privacy lock worth it over a Grade 2 for restroom and dorm doors?
On high traffic openings, yes. The CLX3340 is ANSI/BHMA A156.2 (2022) Series 4000 Grade 1, UL cycle verified to 20 million cycles, and rated past 3,100 in-lb of abusive locked lever torque and 1,600 lbs offset lever pull. The freewheeling Lever Release design is what keeps a kicked or hung-on lever from wrecking the chassis. If the door is a light-duty interior office or closet, a Grade 2 privacy lock such as the Hager 2540 or the Arrow MK02-TA knob version is a cheaper class of hardware for that duty.
9) What lever styles and finishes can I get on the CLX3300 privacy lock to match the rest of my building?
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, plus BSP black suede and WSP white suede powder coat. Since the CLX3300 chassis carries 27 mechanical functions, you can hold one lever style and finish across privacy, passage, classroom and storeroom openings.
10) Does this privacy lock meet ADA lever requirements for a public restroom?
The CLX3300 Series is listed as ADA A117.1 compliant and uses a lever handle rather than a knob, which is what the accessibility requirement calls for on public doors. The series is also windstorm/hurricane certified if the opening is in a coastal jurisdiction.
11) Is the CLX3340 suitable for a behavioral health or patient room door?
The CLX3300 chassis can be ordered with BHSS behavioral health trim and VSL visual status indicators, so the platform covers patient and clinical openings. Note the F77 privacy function itself gives no outside override, so on a patient door where staff need entry you want a function with an outside key or emergency release instead.
12) What is the closest Grade 1 non-keyed lever lock to the CLX3340 if privacy locking is not needed?
The Falcon T101 is a Grade 1 heavy duty cylindrical passage lever lock with pressure release technology, and the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. Both hold the same Grade 1 level as the CLX3340 but are passage function, with no push button locking, while the CLX3340 is ANSI F77 patio/privacy.
13) Which lever lock should I use where the room needs to be locked or unlocked with a key rather than a push button?
The CLX3340 is non-keyed, locked only by push button on the outside lever. For keyed control, the Dexter C1000 classroom is a Grade 1 keyed clutching classroom lever for 1-3/8 inch to 1-3/4 inch doors, the Dexter C1000 classroom security is a Grade 1 keyed classroom security lever, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors.
14) Can a dummy lever be used in place of the CLX3340?
No. Dummy trim such as the BEST 9K Series 1DT Grade 1 single dummy trim or the Accentra 455LN Augusta Grade 1 single dummy is a fixed pull with no latch and no locking. The CLX3340 has a working latchbolt thrown off by the lever and a push button that locks the outside lever, with the inside lever always free.
15) What is the CLX3340 lock body made of, and will it hold up in a humid or wash-down area?
The chassis is steel with a zinc dichromate treatment for corrosion resistance, and the latchbolt is stainless steel. Latch fronts are wrought brass, bronze or stainless steel and strikes are wrought brass or stainless, so you can spec stainless throughout for a damp environment.
16) Can I mix the CLX3340 with keyed CLX3300 locks on the same keyway later?
The CLX3340 itself is non-keyed, so it takes no cylinder. Keyed functions on the same CLX3300 chassis accept all cylinder formats from fixed core through interchangeable core, and ship 6-pin L4 keyway 0-bitted as standard. That means you can put privacy on the restrooms and keyed functions on the corridor doors with identical lever trim and one keying program.
17) Is a keypad lever an alternative to the CLX3340 for a room that needs controlled access?
They solve different problems. The CLX3340 is a mechanical non-keyed patio/privacy lever locked by push button from inside. Code-entry options include the Lockey 2835 mechanical pushbutton keyless lever lock with passage function for 1-3/16 inch to 2 inch doors and the Delaney LP250 Grade 2 electronic keypad leverlock. Those grant entry by code; the CLX3340 controls privacy only.
18) What is a residential-style alternative to the CLX3340 for a decorative interior privacy door?
The Baldwin Estate 5103 privacy lever with 5048 rose is a privacy/bed/bath lever in a decorative estate style. The CLX3340 is a commercial ANSI/BHMA Grade 1 cylindrical lever lock in steel with zinc dichromate treatment, offered in 14 finishes from bright brass through white suede powder coat.
