Corbin Russwin CLX3372-KEYED Apartment Exit/Public Toilet Cylindrical Lever Lock ANSI F88 Grade 1, 1-3/4" to 2" Doors

Commercial-Grade Cylindrical Lever Lock for Apartment Exit and Public Toilet Applications

The Corbin Russwin CLX3372-KEYED is a heavy-duty, ANSI/BHMA Grade 1 cylindrical lever lock engineered for Apartment Exit and Public Toilet applications (ANSI function F88). Designed for doors ranging from 1-3/4" to 2" in thickness with a 2-3/4" backset, this keyed cylindrical lock features a deadlocking latchbolt operable by lever from either side, except when the key inside locks the outside lever — at which point the outside lever freewheels for vandal resistance. Manufactured from steel with zinc dichromate treatment for corrosion resistance, the CLX3372-KEYED is part of the CLX3300 Series, which has been UL cycle-tested to 20 Million Cycles (Verification ID: V875753) and carries a 7 Year Limited warranty, making it an ideal solution for high-traffic commercial and institutional openings.

Professional Features & Benefits

  • Door Thickness & Backset Compatibility: Designed for 1-3/4" to 2" doors with a standard 2-3/4" backset, accommodating a wide range of commercial door configurations.
  • Exceptional Cycle Durability: UL cycle-tested above and beyond requirements at 20 Million Cycles (Verification ID: V875753), delivering long-term reliability in the highest-traffic environments.
  • Superior Strength Ratings: Exceeds 3,100 in-lb abusive locked lever torque with no entry (2.6 times ANSI/BHMA A156.2 requirements); exceeds 1,600 lbs offset lever pull with no entry (8 times ANSI/BHMA A156.2 requirements); and achieves latch retraction with 100 lb preload (2 times ANSI/BHMA A156.2) while maintaining operation in warped doors.
  • Vandal-Resistant Lever Release™ Design: Standard freewheeling Lever Release™ levers prevent lever damage under abuse; independent return springs allow the lock to exceed ANSI/BHMA A156.2 Grade 1 cycle requirements without lever sag.
  • Innovative Push/Turn Button: Patent-pending adjustable push/turn button design withstands excessive abuse against door stops or walls and allows easy door thickness adjustment.
  • Flexible Cylinder & Key System Support: Lock chassis supports all cylinder formats from fixed core to interchangeable core cylinders.

Corbin Russwin CLX3372 NZD 626 – Frequently Asked Questions

1) What does the Corbin Russwin CLX3372 F88 function actually do on an apartment entry door?
F88 is the Apartment Exit/Public Toilet function. The deadlocking latchbolt retracts by lever from either side, except when the key on the inside locks the outside lever. Once locked from inside, the outside lever freewheels and only the outside key retracts the latch. The inside key unlocks the outside lever again, and the inside lever is always free, so the occupant can always get out without a key. That free-egress behaviour is why it suits apartment exits and public restrooms.
2) Will the CLX3372 fit my 1-3/4 inch commercial door, and does handing matter?
Yes on the door. The CLX3372 covers 1-3/4 inch through 2 inch doors, with an adjustable push/turn button that takes up the difference in thickness. Handing is a non-issue, the lock is non-handed, so one part number works on left and right hand openings. Doors thinner than 1-3/4 inch are out of range for this chassis.
3) Will the CLX3372 latch into the strike already in my frame, or do I need to change the prep?
It ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 x 1-1/4 inch lip to center, with a 1-1/4 inch lip length. If your frame already has standard ANSI 4-7/8 inch strike prep, the included strike drops in. The latch is a deadlatch with a square corner front, 2-1/4 x 1-1/8 inches, on a 2-3/4 inch backset, so the door bore must be prepped at 2-3/4 inch backset, not 2-3/8.
4) Can I order the CLX3372 to take my building's existing interchangeable core?
Yes. Four cylinder choices are offered: the standard conventional 6-pin cylinder in the L4 keyway with two nickel silver keys, CL6 less core for Corbin Russwin 6-pin LFIC, CL7 less core for Corbin Russwin 7-pin LFIC, or LC less conventional cylinder if you are supplying your own. If your property is already on a Corbin Russwin small format or large format interchangeable core program, order the CL6 or CL7 and drop your own cores in. The chassis also supports high security systems such as Access 3 and Pyramid.
5) What is the closest Grade 1 keyed cylindrical lever alternative to the Corbin Russwin CLX3372 for a restroom door?
The CLX3372 is an ANSI F88 Apartment Exit/Public Toilet function, Grade 1 cylindrical lever lock with a deadlocking latchbolt that both levers operate unless the inside key locks the outside lever. Among Grade 1 keyed cylindrical levers, the Dexter C1000 Series Classroom (DEX-C1000-CLRM) and Classroom Security (DEX-C1000-CSEC) are the nearest peers by grade and lock type, but their functions are classroom and classroom security rather than apartment exit/public toilet, so the key behavior differs. If the opening specifically calls for F88 shutdown of the outside lever from the inside, the CLX3372 is the function to hold.
6) If the restroom door does not need to be keyed, what can be used instead of the CLX3372?
The CLX3372 is a keyed lock with a conventional 6-pin L4 keyway cylinder and double cylinder keyed function. For an opening that needs no key at all, the Arrow MK02-TA is a Grade 1 privacy function lock rated for 1-3/4 inch to 2 inch doors with a fire rating, and the Falcon K101 is a Grade 1 heavy duty passage lever for 1-3/8 inch to 2-1/4 inch doors, also fire rated. Privacy gives occupant locking with no key cylinder; passage gives free operation both sides at all times.
7) For a 1-3/8 inch thick door, what should I use instead of the CLX3372?
The CLX3372 covers 1-3/4 inch to 2 inch doors, so a 1-3/8 inch leaf falls outside its range. Cylindrical levers that reach down to 1-3/8 inch include the Falcon K101 Grade 1 passage at 1-3/8 inch to 2-1/4 inch, the Dexter C1000 Asylum at 1-3/8 inch to 2 inch, and the Hager 2510 Grade 2 passage at 1-3/8 inch to 2 inch. Match the function you need, since those three are passage and asylum rather than the CLX3372 apartment exit/public toilet function.
8) For a behavioral health or utility room instead of a public toilet, is the CLX3372 the right function?
The CLX3372 is F88 apartment exit and public toilet function, where the inside lever is always free and an inside key locks the outside lever. For asylum or institutional utility openings, which are keyed both sides with no free inside lever, look to the Dexter C1000 Asylum F87 at Grade 1 for 1-3/8 inch to 2 inch doors or the Arrow MK33-BD-CS asylum function heavy duty knob lock. Choose by whether free egress from the inside is required or must be controlled.
9) Is a cylindrical lever lock like the CLX3372 tough enough for a high abuse public restroom, or should I be looking at a mortise lock?
For public toilets and apartment exits this chassis is built for the abuse. The freewheeling Lever Release levers spin rather than break when someone hangs on a locked lever, it takes over 3,100 in-lb of abusive locked lever torque and over 1,600 lbs offset lever pull without entry, and it has been UL cycle tested to 20 million cycles. The body is steel with a zinc dichromate treatment for corrosion resistance, which matters in a wet restroom. A mortise lock is the step up when you need a separate deadbolt or auxiliary latch in the same lock body; for straight latch-and-key restroom or apartment exit duty, this cylindrical does the job with a simpler door prep.
10) Do CLX3372 locks come keyed alike or keyed different?
They are supplied keyed alike unless a different keying is specified on the order. If you need each apartment or restroom on its own key, or a master key system across the building, that has to be called out when you order. Choosing CL6 or CL7 less core instead lets your locksmith handle keying entirely with your own interchangeable cores.
11) Does anything else need to be ordered with the CLX3372 to complete the install?
Not for a standard opening. The lock comes with the deadlatch, the ANSI curved lip strike, and in the standard cylinder configuration a conventional 6-pin L4 cylinder with two nickel silver keys. If you order LC, CL6 or CL7, you are supplying the cylinder or core yourself. Door prep is a standard cylindrical bore at 2-3/4 inch backset on a 1-3/4 to 2 inch door.
12) What looks like a substitute for the CLX3372 but will not work on the same door?
Dummy trim is the common mix-up. The BEST 9K Series 1DT is a Grade 1 single dummy trim with no latch and no keying, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent; Baldwin Estate 5103 half dummy levers are handed, left hand or right hand. None of these retract a latchbolt. The CLX3372 is a non-handed keyed cylindrical lock with a deadlatch, 2-1/4 inch by 1-1/8 inch square corner front on a 2-3/4 inch backset, so dummy trim cannot replace it on an operating door.
13) We want keyless entry on our public restrooms instead of the keyed CLX3372 - what are the options?
The CLX3372 uses a conventional 6-pin L4 keyway cylinder, with less-core LFIC 6-pin and 7-pin and less-cylinder variants for shops running their own key system. If you would rather drop keys entirely, the Lockey 2835 and 2835DC are mechanical pushbutton keyless lever locks for 1-3/16 inch to 2 inch doors, the 2835 noted as ADA compliant, and the Lockey 1150 and 1150S are heavy duty mechanical keypad lever sets for 1-1/8 inch to 2 inch doors, the 1150S with adjustable backset. The Delaney LP250 is an electronic keypad leverlock at Grade 2.
14) Can I match the CLX3372 with non-locking levers on the interior doors of the same building?
Yes, that is a common pairing. The CLX3372 handles the keyed apartment exit and public toilet openings at Grade 1 on 1-3/4 inch to 2 inch doors, and for the non-locking doors nearby the Design Hardware X75 is a Grade 1 passage lever for 1-3/4 inch doors, while the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release. Lever styles and finishes will not match across brands, so if visual consistency matters, note that the CLX3372 itself comes in Armstrong, Newport and Princeton lever designs across 14 finishes.
15) The CLX3372 comes with an L4 keyway - can I get a Schlage C keyway lock instead?
The CLX3372 ships standard with a conventional 6-pin L4 keyway cylinder, and is also offered less conventional cylinder or less LFIC core if you want to supply your own. If the building is keyed to Schlage C, cylindrical locks cataloged with that keyway include the Arrow MK33-BD-CS asylum function, the Cal-Royal AG00 entrance at 2-3/8 inch backset, and the Cal-Royal AG03 classroom at 2-3/4 inch backset. Note those are different lock functions than the CLX3372 apartment exit/public toilet.
