ANSI/BHMA Grade 1 Commercial Cylindrical Lever Lock with Deadlocking Latch and Freewheeling Vandal Resistance

Corbin Russwin CLX3393 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CLX3393 fit a 1-3/4 inch commercial door?
Yes. The CLX3393 service station lever lock is built for doors 1-3/4 inches to 2 inches thick, with a 2-3/4 inch backset as standard. That covers the usual commercial hollow metal or solid core opening, plus the thicker 2 inch leaves you find on some exterior and institutional doors. If your door is thinner than 1-3/4 inches, this is not the right configuration.
2) What does the Service Station function actually do on a lever lock?
Service station (ANSI F92) means the outside lever is locked and unlocked by a slotted push button on the inside. Push the button in and turn it, and the outside lever goes freewheeling while the deadlocking latch is activated, so twisting or wrenching the outside lever does not retract the latch. You unlock it with a key from outside, or by rotating the inside lever with the button returned to its original position. Inside always retracts the latch, so egress is never blocked. It suits a room a staff member locks behind them and re-enters with a key, a stockroom, a service closet, a copy or utility room.
3) Can the CLX3393 go on a fire rated door?
It is fire rated, and the standard latch is a deadlatch with a square corner front measuring 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset. It is an ANSI/BHMA Grade 1 cylindrical lock, which is the heavy duty commercial classification and the one specified for high traffic openings in schools, hospitals and office buildings.
4) Will the CLX3393 latch into the strike that is already in my frame?
The lock ships with an ANSI curved lip strike with a 1-1/4 inch lip length, which is the standard commercial strike prep. If your frame already has an ANSI strike cutout, the replacement drops in. The latch is a deadlatch on a 2-3/4 inch backset, so the bore centerline has to match too, the common alternative being 2-3/8 inch on lighter duty doors.
5) Can I get the Corbin Russwin CLX3393 to work with our existing interchangeable core system?
Yes, and you pick that at order time. Four cylinder choices are offered: the standard conventional 6-pin cylinder in the L4 keyway, CL6 for less core LFIC 6-pin Corbin Russwin, CL7 for less core LFIC 7-pin Corbin Russwin, or LC for less conventional cylinder if you are supplying your own. If your facility is already on Corbin Russwin small format cores, order the CL6 or CL7 and drop your own cores in. It is a single cylinder keyed lock, keyed outside only.
6) My door is 1-3/8 inches thick. Can I still use a Grade 1 lever lock?
Not this configuration of the CLX3393, which starts at 1-3/4 inches. For a thinner leaf, the Falcon K101 is a Grade 1 heavy duty cylindrical passage lock rated 1-3/8 to 2-1/4 inches and fire rated, though it is passage function with no keying. If you need a keyed Grade 1 on a 1-3/8 inch door, the Dexter C1000 entry/office lever covers 1-3/8 to 1-3/4 inches.
7) What is the closest Grade 1 cylindrical lever lock to the Corbin Russwin CLX3393 if I need a keyed function rather than service station?
The CLX3393 is a Grade 1 keyed cylindrical lever lock with the Service Station function, where pushing and turning the slotted button makes the outside lever freewheel and activates the deadlocking latch. If the opening needs a different keyed Grade 1 function, the Dexter C1000 Entry/Office lever lock is Grade 1 with an Entry/Office function and clutching levers, and the Dexter C1000 Classroom lever lock is Grade 1 with a Classroom function. Entry/Office is locked and unlocked from the inside, Classroom is locked and unlocked by key from the outside only, and Service Station is button-set from the inside with key release from the outside.
8) I need Grade 1 lever locks on a corridor but the doors do not need to lock. What matches the CLX3393 without a cylinder?
The CLX3393 is a keyed lever lock with a single cylinder, so it is more lock than an unsecured corridor door needs. For a Grade 1 non-keyed passage lever, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range, and the Falcon T101 is a Grade 1 heavy duty passage lever with Pressure Release Technology. The Design Hardware X75 is another Grade 1 passage lever lockset, listed for 1-3/4 inch doors. All three latch only and carry no cylinder, so they keep the Grade 1 cycle expectation on the door without adding a key to the system.
9) My door is 1-3/8 inch. Will the CLX3393 fit, or do I need a different lever lock?
The CLX3393 is built for 1-3/4 inch to 2 inch doors as standard. On a thinner door, the Falcon K101 Grade 1 passage lever covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 Asylum Grade 1 lock covers 1-3/8 inch to 2 inch, and the Dexter C1000 Entry/Office Grade 1 lever covers 1-3/8 inch to 1-3/4 inch. Confirm the function you need is offered in whichever chassis you pick, since those three cover passage, asylum and entry/office rather than service station.
10) The CLX3393 comes with a Corbin Russwin L4 keyway. What if my building is keyed to Schlage C?
The CLX3393 ships with a conventional 6-pin cylinder in the L4 keyway as standard, and it can also be ordered less cylinder or less core so the chassis takes the cylinder your system already uses. If the door is better served by a lock supplied on Schlage C from the factory, the Cal-Royal AG03 classroom lever is a Grade 2 set with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, and the Cal-Royal AG00 entrance lever is the same keyway on a 2-3/8 inch backset. Keying an existing system across both a Corbin Russwin and a Schlage C keyway means two key sections, so a locksmith should confirm the plan before the doors are split.
11) For a behavioral health or utility room, is the CLX3393 the right function or should I look at an asylum lock?
The CLX3393 is a Service Station lock: the inside lever always retracts the latch and the outside lever is button-locked and key-released. On an opening where both sides must be key-controlled, the Dexter C1000 Asylum lock is a Grade 1 asylum function for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 asylum lock with a ball knob and a conventional Schlage C keyway cylinder. Asylum function keys from both sides, which is the opposite of the always-free inside egress the Service Station gives you.
12) Do I need to specify a hand when I order a Corbin Russwin CLX3393?
No handing to specify. The CLX3393 is non-handed, so one lock covers a left or right hand opening, inswing or outswing. That is worth knowing if you are stocking spares for a building: one part number covers every door in the run.
13) Can I have several CLX3393 locks keyed alike so one key opens them all?
Yes. Keying is a required selection: KD keyed different is standard, KA keyed alike is there for a run of locks that should share one key, which is what you want across a set of service closets or a tenant suite. There is also a free text field for special cylinder or keying requirements if the locks have to fit an existing master key system.
14) What lever styles and finishes does the Corbin Russwin CLX3393 come in?
Three lever designs: AZD Armstrong, NZD Newport and PZD Princeton. Fourteen finishes run from 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 and 626 satin chrome, through to 722 black oxidized bronze oil-rubbed, BSP black suede and WSP white suede powder coat. If you are matching existing openings in a commercial building, 626 satin chrome is the most common commercial finish and the usual match for existing hardware.
15) Should I use a service station lock or a storeroom lock for a supply room?
Depends on whether staff need to leave the room unlocked sometimes. A storeroom function is always locked outside, key every time, no way to leave it free. Service station like the CLX3393 gives you the choice: with the push button out, the outside lever works freely for the workday, and when you push and turn the button the outside lever freewheels and the deadlocking latch sets. If you want it locked permanently with no user override, look at a storeroom lever such as the Hager 2580 with the Withnell lever or the Cal-Royal AG05 with a deadlocking latchbolt, both Grade 2 rather than Grade 1.
16) How well does the CLX3393 hold up to abuse on a high traffic door?
The chassis is steel, zinc dichromated for corrosion resistance, which matters on exterior and damp openings. The bigger point for vandalism is the function itself: once locked, the outside lever freewheels, so someone hanging off it or wrenching it is turning a lever that is not connected to the latch. That is the failure mode that kills locks in schools and multi-tenant corridors. It carries ANSI/BHMA Grade 1, the heavy duty commercial rating.
17) Is a cylindrical lever lock like the CLX3393 the right choice, or do I need a mortise lock?
A cylindrical lock like this bores through the door face, two holes and an edge prep, and it is the faster and cheaper install. A mortise lock needs a pocket routed into the door edge and is what you go to for heavier security or when you need functions a bored lock cannot do. For a service station opening on a standard 1-3/4 to 2 inch door with a 2-3/4 inch backset, the cylindrical is the normal specification and it hits Grade 1 anyway. Retrofitting a mortise-prepped door with a cylindrical lock means filling the pocket, so match the lock to the prep already in the door.
18) Is a Grade 3 residential lever an alternative to the Corbin Russwin CLX3393?
No. The CLX3393 is a Grade 1 commercial cylindrical lever lock. The Cal-Royal AUS00 entrance/office lever is Grade 3, the Callan Artino and Callan Bennett entrance leversets are Grade 3, and the Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. Grade 3 sets are tested to the lowest ANSI/BHMA tier and are a different class of hardware from a Grade 1 commercial chassis, so they are not a like-for-like replacement on an opening specified for Grade 1.
19) Can I use a Grade 2 lever lock instead of the Corbin Russwin CLX3393 on a lower-traffic door?
The CLX3393 is certified to ANSI/BHMA Grade 1 for commercial use. Where the traffic on the opening allows a Grade 2 chassis, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, the Hager 2525 is a Grade 2 commercial entry lock with a lever handle in the same thickness range, 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. Grade 2 chassis are tested to a lower cycle and strength threshold than Grade 1, so match the grade to the door's duty rather than swapping across a whole facility.
20) What do I order for the inactive leaf or a pull-only door where I am installing CLX3393 lever locks elsewhere?
The CLX3393 is a functioning keyed lockset and is not the part for a leaf that only needs matching trim. For dummy trim at Grade 1, the BEST 9K Series 1DT single dummy trim lever is a Grade 1 heavy duty non-keyed dummy, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever. The BEST 7KC Series 1DT is the medium duty Grade 2 equivalent. Dummy trim has no latch and no chassis, so it mounts to the face of the door for appearance and pull only.
21) I want keyless access instead of the keyed CLX3393. What lever locks work without a key?
The CLX3393 uses a conventional 6-pin cylinder in the L4 keyway. For openings you would rather run on a code, the Lockey 2835 mechanical pushbutton keyless lever lock has a passage function and is ADA compliant for 1-3/16 inch to 2 inch doors, the Lockey 2835DC adds a double combination in the same thickness range, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for 1-1/8 inch to 2 inch doors. The Delaney LP250 is an electronic keypad leverlock at Grade 2. Mechanical keypad sets carry no cylinder, so they sit outside a master key system rather than joining one.
22) Is a privacy lever lock the same thing as the Service Station function on the CLX3393?
They are not the same. On the CLX3393 the outside lever is locked with a slotted push button and is released by key from the outside or by turning the inside lever, and it is a keyed single-cylinder lock. A privacy set has no key. The Arrow MK02-TA is a privacy knob lock for 1-3/4 inch to 2 inch doors with a fire rating, the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever. Privacy sets suit a restroom or a bedroom; they will not give staff key access to a service opening.
23) I need a lever, not a knob. Which of the cylindrical locks are knob sets rather than lever sets?
The CLX3393 is a lever lock, offered with the Armstrong, Newport and Princeton lever designs. Several cylindrical alternatives are knob sets and will not satisfy a lever requirement: the Arrow HK11-BB is a turn-pushbutton entrance lock with a ball knob, the Arrow MK02-TA privacy lock uses a Tudor knob, and the Arrow MK33-BD-CS asylum lock uses a ball knob. Where ADA lever operation is required on the opening, those knob sets are the wrong trim regardless of function.
24) Are the decorative brass leversets an equivalent to the CLX3393 for a commercial opening?
They serve a different opening. The CLX3393 is a commercial Grade 1 cylindrical lock with a fire rating and a steel, zinc dichromated chassis. The Baldwin Estate 5103 with 5048 rose comes in passage, privacy and half dummy versions, the Emtek Classic Brass Cortina and Arts and Crafts leversets are dummy pairs, and the Deltana Manchester, Morant and Linstead levers are entry sets for 1-3/8 inch to 2 inch doors. Those are decorative residential-style trim; for a fire-rated commercial door the Grade 1 cylindrical chassis is what the spec calls for.
25) I need a matching dummy lever on an inactive leaf to go with my Grade 1 lever locks. What works?
A dummy trim has no latch at all, it is a pull mounted to the face for an inactive leaf or a closet door. In Grade 1, the BEST 9K Series 1DT single dummy trim lever and the Accentra 455LN Augusta heavy duty single dummy from the 5400 Series both cover that. They are separate brands from Corbin Russwin, so the lever shape and finish will not be an exact visual match to an AZD, NZD or PZD lever, worth weighing if the two doors sit side by side.
