Corbin Russwin CLX3352 NZD 626 – Frequently Asked Questions

1) How does the CLX3352 classroom intruder function actually work during a lockdown?
The outside lever is locked and unlocked by turning a key in either the inside or the outside lever, so a teacher can secure the door from inside the room without stepping into the corridor. The inside lever always retracts the deadlocking latchbolt, so egress is never blocked whether the outside is locked or free. That is ANSI function F110, single cylinder keyed.
2) Can I get the CLX3352 to work on my existing small format interchangeable core key system?
Cylinder format is an ordering choice. Standard is a conventional 6-pin cylinder in the L4 keyway, 0-bitted. You can instead order CL6 less core for a Corbin Russwin 6-pin large format interchangeable core, CL7 less core for the 7-pin LFIC, or LC less conventional cylinder if you are supplying your own. Order less core when the building already runs an LFIC system and you want these classrooms on the existing keying.
3) Can a Grade 1 classroom lever like the CLX3352 go on a fire rated door?
It is fire rated, and the CLX3300 platform carries UL/cUL 3-hour listing and meets NFPA 80. For a fire door you want the 3/4 inch deadlocking fire latch option rather than the 1/2 inch standard throw latch, since deeper throw is what holds the leaf in the frame under positive pressure. The lock also meets ADA A117.1 for lever operation.
4) Will the CLX3352 latch into the strike that is already in my frame?
The lock ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 x 1-1/4 inch lip to center, with a 1/2 inch latchbolt throw. If your frames already carry ANSI strike prep, the existing cutout takes it. The latch front is a square corner deadlatch, 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset, so a door edge already mortised for a standard ANSI front will not need rework. Round corner edge preps will.
5) Is there enough stile on my aluminum or narrow rail door for a CLX3352?
You need at least 4-1/2 inch stile for the CLX3300 chassis. Anything narrower than that, a typical narrow stile storefront leaf, will not take this cylindrical lock and you should be looking at a narrow stile device instead. Backset options of 2-3/8, 3-3/4 and 5 inches exist alongside the 2-3/4 inch standard, which is how you get the lock centered correctly on deeper stiles and glass lites.
6) Is there a Grade 2 classroom lever lock instead of the Corbin Russwin CLX3352?
Yes. The Cal-Royal AG03 is a classroom lever from the AG Series with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset — the same 2-3/4 inch backset the CLX3352 uses as standard, so the door prep centerline matches. The CLX3352 is ANSI/BHMA Grade 1 and ships standard with a conventional 6-pin cylinder in the L4 keyway, which matters if the building is keyed into a Corbin Russwin system; the AG03's Schlage C keyway suits a facility already keyed that way.
7) What is the closest Grade 1 classroom cylindrical lever lock to the Corbin Russwin CLX3352?
The Dexter C1000 Series classroom cylindrical lever lock is the nearest equivalent: it is a Grade 1 keyed cylindrical lever lock with a Classroom function, the same duty class and lock type as the CLX3352. The difference that decides an opening is door thickness — the Dexter C1000 classroom lock covers 1-3/8 inch to 1-3/4 inch doors, while the CLX3352 is built for 1-3/4 inch to 2 inch doors as standard. On a 2 inch door the Corbin Russwin is the one that fits without an optional thickness kit; on a 1-3/8 inch door the Dexter covers it out of the box.
8) Do I need to specify a hand when ordering a Corbin Russwin CLX3352 lever?
No handing to specify. The CLX3352 is non-handed, so one part number covers left and right hand openings. That is what makes it practical to stock a single lock for a whole corridor of classrooms swinging both ways. You do still choose lever design, Armstrong, Newport or Princeton, and finish.
9) What do I order if my classroom doors are 1-3/8 inch or thicker than 2 inches?
Two suffixes cover it. D138 handles 1-3/8 inch doors, and D214 handles anything over 2 inches up to 2-1/4 inches. Inside the standard 1-3/4 to 2 inch band you adjust with the patented push/turn button on the lock itself, no extra part. Survey the doors before you order a run, mixed-thickness buildings are where the wrong suffix shows up on install day.
10) Is a Grade 1 lock like the CLX3352 overkill for a school corridor, or should I save money with Grade 2?
For classroom doors that get hit hundreds of times a day, Grade 1 is the right call. The CLX3300 chassis is UL cycle tested beyond 20 million cycles, exceeds 3,100 in-lb abusive locked lever torque and 1,600 lbs offset lever pull, and the Lever Release freewheeling design lets an abused lever spin instead of breaking the chassis. Grade 2 classroom options exist, the Cal-Royal AG03 for one, and they suit lower-traffic interior openings, not a high school corridor.
11) Can I get a behavioral health or ligature resistant version of the Corbin Russwin CLX3300 classroom lock?
The CLX3300 platform offers BHSS behavioral health trim and VSL visual status indicators, which is what healthcare and behavioral units specify so staff can read occupancy from the corridor without trying the lever. Those are trim selections on the same Grade 1 chassis, so the door prep and the 2-3/4 inch backset stay the same across the facility.
12) I need an electrified version for access control on some of these doors. What does the CLX3300 offer?
The series runs 27 mechanical and 2 electrified functions, so you can keep one chassis family across mechanical and card-reader openings. Electrified units take 12VDC or 24VDC with a working range of 10.2 to 26.4VDC, draw 10mA continuous and 500mA peak, use the ElectroLynx 8-pin molex connector, and are UL294 listed. Rated operating temperature is -13F to 151F. The CLX3352 itself is the keyed mechanical classroom function.
13) Does the CLX3352 need a special door prep, or does it fit a standard commercial bore?
Door prep follows ANSI/SDI A250.14, the standard commercial hollow metal prep, on a 2-3/4 inch backset. If your doors were previously fitted with a Grade 1 cylindrical lock on that prep, this goes back in the same holes. Minimum stile is 4-1/2 inches, and the latch front is 2-1/4 x 1-1/8 inches square corner.
14) I need matching non-keyed levers for the corridor and closet doors alongside a classroom lock. What works?
For the openings that need no key, a Grade 1 passage lever keeps the duty level consistent with the CLX3352's Grade 1 heavy duty rating. 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; the Falcon T101 is a Grade 1 heavy duty cylindrical passage lever with Pressure Release Technology. Both are non-keyed, so they carry no cylinder to key into the classroom's system. The CLX3352 itself is non-handed as well, so lever orientation is not a variable on either side of the order.
15) Will a dummy lever work on the inactive leaf of a pair with a CLX3352 on the active leaf?
A dummy trim has no latch and no chassis — it is surface trim only, so it cannot substitute for the CLX3352 anywhere the door has to latch. On an inactive leaf it is the right part. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, matching the CLX3352's Grade 1 heavy duty rating, and the Accentra 455LN Augusta from the 5400 Series is a Grade 1 dummy cylindrical lever. The BEST 7KC Series 1DT single dummy trim is Grade 2 medium duty if the leaf sees lighter handling.
16) Can I use a Grade 3 residential lever on a school or commercial corridor door?
The Corbin Russwin CLX3352 is a commercial Grade 1 heavy duty lever built to ANSI/BHMA Grade 1 for institutional traffic. The Cal-Royal AUS00 entrance/office lever is Grade 3, the Callan Artino and 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. Those are residential-duty cycles and none carries a classroom function, so on a corridor or classroom door under a commercial spec they will not satisfy the drawing.
17) Does a Schlage cylinder adapter let me put my existing key system into a Corbin Russwin CLX3352?
No. The Accentra 107S is a Schlage cylinder adapter kit made for Yale hardware, not for Corbin Russwin chassis. The CLX3352 ships standard with a conventional 6-pin cylinder in the L4 keyway and is also ordered less core for Corbin Russwin LFIC 6-pin or 7-pin cores, or less conventional cylinder if the cylinder is being supplied separately. Ordering it less cylinder is the route to putting an existing core into it.
18) What Grade 1 lever should I use for a privacy or restroom door in the same building as a CLX3352?
The Arrow MK02-TA is the closest match in the set for a privacy opening — a fire rated privacy/bed/bath cylindrical lock for 1-3/4 inch to 2 inch doors, the same door thickness range the CLX3352 covers as standard, so both prep into the same doors. It uses a Tudor knob rather than a lever, which is the detail to check against an ADA requirement; the CLX3352 is a lever throughout, offered in the Armstrong, Newport, and Princeton designs.
19) Is a Design Hardware X75 a substitute for the Corbin Russwin CLX3352?
Not for a keyed opening. The Design Hardware X75 from the X Series is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors — it matches the CLX3352's Grade 1 rating but carries a passage function, meaning no cylinder and no locking. The CLX3352 is a keyed single cylinder classroom lock. Where the two do line up is duty class on a 1-3/4 inch door, so the X75 is a sensible companion for the non-locking openings on the same job. The Design Hardware J75 is the Grade 2 flat-lever passage equivalent.
20) What finishes does the Corbin Russwin CLX3352 come in for matching the rest of a building?
Fourteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E and 613L dark oxidized bronze, 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. 626 satin chrome is the usual institutional standard, so that is what most school and healthcare specs land on.
21) Will the CLX3352 hold up in an exterior or coastal opening?
The chassis is steel with a zinc dichromate treatment for corrosion resistance, and the platform is windstorm and hurricane certified. That covers heavy-duty commercial exterior doors. The latchbolt itself is stainless steel, and the front comes in wrought brass, bronze or stainless.
22) What matching passage or dummy levers can I use on the non-locking doors in the same building?
Keep the trim family consistent by ordering the CLX3300 in one of its other functions, the series runs 27 mechanical functions on the same Armstrong, Newport or Princeton lever designs and the same finish list. If you are working across brands and only need Grade 1 non-keyed openings, ZenSupply stocks the Falcon K101 Grade 1 passage lock, fire rated and fitting 1-3/8 to 2-1/4 inch doors, and the BEST 9K Series 1DT single dummy trim.
