Corbin Russwin CLX3375 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CLX3375 corridor lock fit a 1-3/4 inch metal door with a 2-3/4 inch backset prep?
That is the standard prep for it. The CLX3375 is built for 1-3/4 inch to 2 inch doors with a 2-3/4 inch backset, and the door prep follows ANSI/SDI A250.14. Optional backsets of 2-3/8, 3-3/4 and 5 inches are available, and a D138 option covers 1-3/8 inch doors while D214 covers over 2 inch up to 2-1/4 inch. Minimum stile is 4-1/2 inches, so it will not go on a narrow stile aluminum door.
2) What does the F90 corridor/dormitory function actually do at the door?
Either lever throws the latch off until someone pushes the button on the inside, which locks the outside lever. From then on the outside lever needs a key. Turning the inside lever releases the button, and so does closing the door, so the room does not stay locked out by accident. The inside lever is always free for egress. That is the behaviour dorm rooms and corridor doors want: staff or a resident can secure the outside without anyone getting trapped in.
3) Can the CLX3375 go on a fire rated corridor door in a dormitory or hospital?
It is fire rated, UL and cUL listed for 3 hours, and meets NFPA 80 and ADA A117.1. The lock is also Windstorm/Hurricane certified. For fire door use, order the 3/4 inch deadlocking fire latch option rather than the standard 1/2 inch throw latch.
4) Will the CLX3375 latch into the strike that is already in my frame?
The standard latch is a stainless steel deadlatch with a 1/2 inch throw and a square corner front measuring 2-1/4 x 1-1/8 inches, shipping with an ANSI curved lip strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center. If your frame already has an ANSI 4-7/8 inch strike cutout, it drops in. A frame prepped for a T-strike or a round corner latch face needs to be changed, or the frame reworked.
5) Can I get the CLX3375 to work with our existing interchangeable core keying system?
Yes, and you pick the core format at order. Options are CL6 for less core LFIC 6-pin Corbin Russwin, CL7 for less core LFIC 7-pin Corbin Russwin, the standard conventional 6-pin cylinder in L4 keyway, or LC less conventional cylinder if you are supplying your own. The chassis takes all cylinder formats from fixed core through interchangeable core. Conventional cylinders ship 0-bitted as standard, and keying is ordered keyed different or keyed alike.
6) Is there a storeroom lever I can order instead of the CLX3375 for a door that must stay locked at all times?
Two storeroom levers cover that opening: the Cal-Royal AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch thick, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for doors 1-3/8 inch to 2 inch thick. Neither offers the CLX3375's pushbutton, which is what lets staff leave a corridor door unlocked during the day and secure it without a key.
7) Which lever locks look like a substitute for the CLX3375 but are not keyed?
Several Grade 1 levers in the same cylindrical family carry no cylinder at all. The Falcon K101 is a Grade 1 heavy duty passage lock, fire rated, non-handed, for doors 1-3/8 inch to 2-1/4 inch; the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology; the Design Hardware X75 is a Grade 1 passage lever for 1-3/4 inch doors; and the BEST 9K Series 1DT is Grade 1 heavy duty single dummy trim with no latch at all. The CLX3375 is keyed with a single cylinder, shipping standard with a conventional 6-pin L4 keyway cylinder. If the door needs to lock, a passage or dummy lever will not do it.
8) For a behavioral health or institutional room, is the CLX3375 the right lock or should I use an asylum function?
An asylum or institution function keys both sides, which the CLX3375 does not do: it is a single cylinder lock whose inside lever is released by turning it or by closing the door. The Dexter C1000 Series Asylum lock is Grade 1 F87 asylum function for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 asylum lock with a ball knob and a conventional Schlage C keyway cylinder at heavy duty. Use one of those where the room must be keyed from both sides.
9) I need a fire rated lever for a rated corridor opening. Which options carry a fire rating besides the CLX3375?
The CLX3375 is fire rated and non-handed. Among the comparable levers, the Falcon K101 Grade 1 passage lock is fire rated with non-handed levers, and the Arrow MK02-TA privacy lock is fire rated for doors 1-3/4 inch to 2 inch. Both of those are non-keyed, so on a rated corridor door that also has to lock, the keyed CLX3375 is the one that does both.
10) We key our building on Schlage C. Does that rule out the CLX3375 in favor of another lever?
The CLX3375 ships standard with a conventional 6-pin L4 keyway cylinder, and it can also be ordered less cylinder or less core for Corbin Russwin 6-pin or 7-pin LFIC. Levers that come on Schlage C include the Cal-Royal AG00 entrance lever, Grade 2, 6-pin Schlage C keyed different, and the Cal-Royal AG03 classroom lever, also 6-pin Schlage C keyed different. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware.
11) Do I have to specify handing when I order a Corbin Russwin CLX3375?
No handing to specify. The CLX3375 is non-handed, so one part number covers left and right hand openings. That is what you want when you are stocking spares for a building full of dorm or corridor doors, since a single lock covers any door in the run.
12) How do I keep multiple CLX3375 locks on one key for a building?
Order keyed alike (KA) instead of the standard keyed different (KD) when a group of doors should share one key. There is also a free-text field for special cylinder or keying requirements, which is where a master key system, an existing keyway, or a specific bitting gets called out. Single cylinder keyed function, so the key operates the outside only.
13) Is a Grade 1 cylindrical lever lock worth it over a Grade 2 for a college dorm corridor?
On high traffic openings the durability gap is the whole point. The CLX3375 meets ANSI/BHMA A156.2 (2022) Series 4000 Grade 1, was UL cycle tested to 20 million cycles, and exceeds 3,100 in-lb abusive locked lever torque and 1,600 lbs offset lever pull. The Lever Release freewheeling design lets the locked lever spin instead of transmitting force into the chassis, which is what saves locks in dorms. If the opening is low traffic and non-critical, a Grade 2 lever such as the Hager 2580 storeroom or the Cal-Royal AG05 storeroom is the lighter class of product.
14) I need a classroom function lock, not corridor. What should I order instead of the CLX3375?
The CLX3375 is corridor/dormitory F90, where the inside pushbutton locks the outside lever. That is the wrong function for a classroom, where the teacher keys the outside lever locked and the button plays no part. Within the same CLX3300 family the CLX3352 Classroom Intruder locks from either side with always-free egress, which is what most schools now specify. From other brands, the Dexter C1000 classroom and C1000 classroom security levers are Grade 1 alternatives.
15) Does a corridor lock need a separate deadbolt on a dorm room door?
The CLX3375 is a single bored cylindrical lock with a 1/2 inch throw deadlatch, not a deadbolt lock. The latch deadlocks against carding but the security is the latch, not a bolt. If the specification calls for a bolt, you are adding a separate deadbolt above the lock and cutting a second bore, or moving to a mortise lock instead. For the fire door version, the 3/4 inch deadlocking fire latch is the option to call out.
16) Can I get the CLX3375 in an electrified version for access control?
The CLX3300 chassis is offered with 27 mechanical and 2 electrified functions. Electrified units run 12VDC or 24VDC, draw 10mA continuous with a 500mA peak, use the ElectroLynx 8-pin molex connector, and are UL294 listed. The CLX33900 EcoFlex version accepts 10.2 to 26.4VDC and operates from -13F to 151F. If the corridor door is going on a card reader, that is the direction, not the mechanical CLX3375.
17) Can I match a Grade 1 passage or dummy lever to these keyed corridor locks on the same run of doors?
Not from the CLX3375 itself, which is a keyed corridor/dormitory lock. Keep the trim consistent by ordering the matching non-keyed function from the same CLX3300 family, since the series covers 27 mechanical functions on the one chassis with the same Armstrong, Newport or Princeton lever. Where a different brand is acceptable on closet and mechanical doors, Grade 1 non-keyed options include the Falcon K101 passage, the Falcon T101 passage, the BEST 9K single dummy trim and the Design Hardware X75 passage lever.
18) Will this lever lock work on a 1-3/8 inch older interior door?
Not as standard. The CLX3375 ships set for 1-3/4 inch to 2 inch doors; 1-3/8 inch requires the D138 option specified at order. The patented adjustable push/turn button is what handles thickness adjustment within the range. If you are buying off the shelf for a mix of older 1-3/8 inch interior doors, a lock rated across that span, such as the Falcon K101 at 1-3/8 to 2-1/4 inches or the Dexter C1000 asylum at 1-3/8 to 2 inches, avoids the option call-out.
19) What do I order to match the CLX3375 on the inactive leaf or a closet door in the same corridor?
For an opening that needs the lever look without any latch, the BEST 9K Series 1DT single dummy trim is Grade 1 heavy duty, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever from the 5400 Series. For a latching but unlocked door, the Design Hardware X75 is a Grade 1 passage lever for 1-3/4 inch doors. The CLX3375 itself is the keyed corridor/dormitory lock and comes in Armstrong, Newport and Princeton lever designs, so match the trim across the run.
20) Can a keypad or keyless lever replace the CLX3375 where I do not want to issue keys?
Keyless options in the same lever format include the Lockey 2835 mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 inch to 2 inch, the Lockey 2835DC double combination version at the same thickness range, and the Lockey 1150 heavy duty mechanical keypad lever set for doors 1-1/8 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The CLX3375 is a keyed mechanical lock using a conventional 6-pin L4 keyway cylinder, so a keypad unit changes how credentials are managed across the building.
21) My doors are 1-3/8 inch thick. Which comparable lever fits when the standard CLX3375 does not?
The CLX3375 covers 1-3/4 inch to 2 inch doors as standard. Levers built for thinner doors include the Falcon K101 Grade 1 passage lock at 1-3/8 inch to 2-1/4 inch, the Hager 2510 Grade 2 passage lever with Withnell design at 1-3/8 inch to 2 inch, the Hager 2525 Grade 2 entry lock at the same range, and the Dexter C1000 Entry/Office Grade 1 lever at 1-3/8 inch to 1-3/4 inch. Note that the passage units do not lock.
22) The dorm room bathroom needs privacy, not corridor function. What takes the place of the CLX3375 there?
Privacy levers and knobs for bed and bath include the Arrow MK02-TA privacy cylindrical lock with a Tudor knob, non-keyed, fire rated, for doors 1-3/4 inch to 2 inch; the Kwikset 300BRNL RDT Breton privacy lever at Grade 3 for doors 1-3/8 inch to 1-3/4 inch; and the Baldwin Estate 5103 privacy lever with the 5048 rose. The CLX3375 is a keyed corridor/dormitory lock, so it belongs on the room entry rather than the bath door.
23) What is the difference between the CLX3375 and a residential-grade entry lever from Kwikset or Master Lock?
The Kwikset 200BRNL Breton passage lever and the Kwikset 200DL Delta passage lever are Grade 3 interior hall and closet locks, and the Master Lock BC Series return style keyed entry lockset is a Grade 3 entrance lock. The CLX3375 is ANSI/BHMA Grade 1 commercial, non-handed, fire rated, keyed with a single cylinder for corridor and dormitory openings on doors 1-3/4 inch to 2 inch. The Grade 3 units are built for interior residential doors rather than institutional corridors.
24) What finishes and lever styles does the Corbin Russwin CLX3375 come in?
Three lever designs, Armstrong (AZD), Newport (NZD) and Princeton (PZD), across fourteen finishes: 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. For matching existing openings in a building, 626 satin chrome is the usual commercial standard. The lock body itself is steel, zinc dichromated for corrosion resistance.
25) Is there a behavioral health or status indicator version of this Corbin Russwin lever lock?
Both are offered on the CLX3300 platform: BHSS behavioral health trim, for ligature-resistant openings in psychiatric and healthcare settings, and VSL visual status indicators that show at a glance whether the door is locked. Those are trim and option selections on the same chassis, so the door prep does not change.
