Corbin Russwin CL3372-KEYED Apartment Exit/Public Toilet Extra Heavy-Duty Cylindrical Lever Lock with Lever Release Vandal Resistance

Grade 1 Extra Heavy-Duty Cylindrical Lockset for Commercial Apartment and Public Facility Applications

The Corbin Russwin CL3372-KEYED is an extra heavy-duty, Grade 1 cylindrical lever lock engineered for Apartment Exit/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 lockset features a deadlocking latchbolt operable by lever from either side, except when the key inside locks the outside lever—placing the outside lever in a freewheeling position. The key outside retracts the latchbolt, the key inside unlocks the outside lever, and the inside lever remains always free. Constructed with steel and zinc dichromated components for corrosion resistance, the CL3372 is built to deliver quiet, dependable operation across demanding commercial environments.

Corbin Russwin CL3372 NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CL3372 apartment exit function actually work at the door?
The CL3372 is ANSI F88, apartment exit / public toilet. Both levers operate the deadlocking latchbolt normally. The key on the inside locks the outside lever, which then freewheels; the key on the outside still retracts the latchbolt so staff or a manager can get in. Turning the inside key again unlocks the outside lever. The inside lever is always free, so egress is never blocked, which is why this one shows up on public restrooms and apartment corridor doors.
2) Can I use the CL3372 on a fire rated apartment corridor door?
It is fire rated and UL-cUL listed, and it carries California State Fire Marshal listing. Note the latch: the standard latchbolt is stainless steel with a 1/2 inch throw, and a 3/4 inch fire latch is available as an option. On rated openings check what your door and frame listing calls for on latch throw before you pick the latch.
3) Can I get the CL3372 to work on my building's existing key system?
Yes, several ways. Standard build is a conventional 6-pin cylinder in the L4 keyway, 0-bitted, and the series accepts 6 or 7 pin conventional cylinders and all keying levels. If you run a Corbin Russwin large format interchangeable core system, order CL6 or CL7 less core and drop your own cores in. If you key in house or use another cylinder line, order LC, less conventional cylinder. Keyed alike and keyed different are both available.
4) Is this lock tough enough for a high traffic public restroom where levers get yanked on?
That is what the Lever Release design is for. When the outside lever is locked it rotates freely instead of resisting, so someone hauling on it does not break the chassis or spindle. The lock is Grade 1 extra heavy duty under ANSI/BHMA A156.2 Series 4000, with a steel zinc dichromated chassis for corrosion resistance and independent return springs so the levers do not sag over time. Anti-rotational through bolts at 6 and 12 o'clock keep the roses tight to the door.
5) What is the closest Grade 1 alternative to the Corbin Russwin CL3372 for a public restroom door that does not need key control?
If the opening does not need a keyed outside lever, a Grade 1 non-keyed cylindrical lever is the simpler path. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, covering doors 1-3/8 inch to 2-1/4 inch and carrying a fire rating. The Falcon T101 is also a Grade 1 heavy duty cylindrical passage lever. The difference is real: the CL3372 is a keyed double cylinder lock with a deadlocking latchbolt where the key inside locks the outside lever and the inside lever stays always free, so it gives a restroom attendant lockout capability that a passage function does not.
6) Is there a Grade 2 lever lock I can use instead of the Corbin Russwin CL3372 on a lower-traffic apartment door?
For a lighter-duty opening, Grade 2 keyed cylindrical levers include the Hager 2580 storeroom function with the Withnell lever for doors 1-3/8 inch to 2 inch, the Hager 2525 entry function in the same thickness range, and the Cal-Royal AG05 Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. None of those is the apartment exit function: the CL3372 is ANSI F88, where the key outside retracts the latchbolt and the key inside unlocks the outside lever, which is the behavior that lets a unit or restroom be secured from inside and still opened by staff.
7) What should I order instead of the Corbin Russwin CL3372 for a classroom or an institutional opening?
Those are different ANSI functions, not finishes of the same lock. For classrooms, the Dexter C1000 is offered in a Grade 1 classroom clutching keyed lever and in a Grade 1 classroom security version, both for doors 1-3/8 inch to 1-3/4 inch. For institutional and utility openings, the Dexter C1000 asylum function is Grade 1 ANSI F87 for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum knob lock with a conventional Schlage C keyway cylinder. The CL3372 is the Apartment Exit/Public Toilet function, where the inside lever is always free, so it is not a fit where you need key control from both sides at all times.
8) Do I have to specify handing when I order a CL3372?
No. The CL3372 is non-handed, so one lock covers left and right hand openings. The only exception Corbin Russwin calls out is FZD trim. With the Armstrong, Newport and Princeton lever designs offered here, handing is not part of the order.
9) I need matching passage and privacy levers for the rest of the apartment units. What pairs with a Grade 1 cylindrical lever like this?
Stay in the CL3300 series if you want the lever design and finish to match exactly across the unit. If you are filling out lower traffic openings with other lines, Falcon's K101 is a Grade 1 passage cylindrical lock rated for 1-3/8 to 2-1/4 inch doors and fire rated, and the Falcon T101 is a Grade 1 heavy duty passage lever. For closets and interior doors where Grade 2 is enough, the Hager 2510 Withnell passage lever covers 1-3/8 to 2 inch doors. Single dummy trim in Grade 1 is available as the BEST 9K 1DT.
10) Is there an electrified version of the CL3300 cylindrical lock for access control?
Yes, the CL33900 electrified series. It is offered fail safe or fail secure, at 12 or 24 VAC/VDC, drawing 250mA at 12V and 150mA at 24V on a continuous duty solenoid. Every electrified unit uses the ElectroLynx 8-pin connector, so it plugs into an ElectroLynx door loop or hinge without cutting and splicing in the field. The mechanical CL3372 covered here is not electrified.
11) Does the CL3372 meet accessibility requirements for lever operation?
The CL3300 series lever locks are listed to ANSI A117.1 accessibility, and the lever handle itself is the operable form that satisfies the no tight grasping or twisting requirement. That matters on apartment corridor and public restroom doors in particular, which is exactly where this function lands.
12) Would a privacy lever work in place of the Corbin Russwin CL3372 on a public toilet door?
Only for a single-occupancy room where no key control is wanted. Privacy options include the Hager 2540 Grade 2 with the Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA privacy knob lock rated for 1-3/4 inch to 2 inch doors and fire rated, and the Baldwin Estate 5103 privacy lever with the 5048 rose. A privacy set locks from inside with a thumbturn and releases with an emergency tool. The CL3372 is a keyed double cylinder lock with a 6-pin L4 keyway cylinder, so it ties the restroom into a building keying system in a way a privacy set does not.
13) I need a matching inactive leaf or closet door lever alongside the Corbin Russwin CL3372 - what do I order?
For a dummy or passage opening on the same run of doors, Grade 1 options include the BEST 9K Series 1DT single dummy trim cylindrical lever, the Accentra 455LN Augusta Grade 1 single dummy cylindrical lever in the 5400 Series, and the Design Hardware X75 Grade 1 passage lever for 1-3/4 inch doors. The BEST 7KC Series single dummy is the Grade 2 medium duty equivalent. None of these is keyed, so they will not carry the CL3372's L4 keyway cylinder or its deadlocking latchbolt - they are trim and latch only.
14) My openings are keyed to Schlage C - do I have to give up the Corbin Russwin CL3372?
The CL3372 ships standard with a conventional 6-pin L4 keyway cylinder and is also offered less conventional cylinder or less core for Corbin Russwin 6-pin and 7-pin LFIC, so a locksmith can key it to the Corbin Russwin system of your choice. If the building is committed to Schlage C, cylindrical levers already built on that keyway include the Cal-Royal AG00 entrance lever with a 6-pin Schlage C keyway on a 2-3/8 inch backset, the Cal-Royal AG03 classroom lever with a 6-pin Schlage C keyway on a 2-3/4 inch backset, and the Arrow MK33-BD-CS asylum lock with a conventional Schlage C keyway cylinder.
15) Is an entrance or office function lever the same thing as the Corbin Russwin CL3372?
No. Entrance and office function locks such as the Falcon B511CP6D Grade 2 entry/office cylindrical lever, the Hager 2525 Grade 2 commercial entry lever, and the Arrow HK11-BB turn-pushbutton entrance lock lock and unlock the outside lever from a button or turn on the inside. The CL3372 is ANSI F88 apartment exit: the key inside locks the outside lever and the key outside retracts the latchbolt, so control is by key rather than by a pushbutton anyone can set. That distinction matters in multi-family and public restrooms where a resident should not be able to leave the outside lever locked by accident.
16) What is the difference between the Corbin Russwin CL3372 and the Dexter C1000 asylum lock for a utility room?
Both are Grade 1 cylindrical levers. The Dexter C1000 asylum is ANSI F87 and covers doors 1-3/8 inch to 2 inch. The CL3372 is ANSI F88 with a double cylinder keyed function, a 2-3/4 inch backset standard, and doors 1-3/4 inch to 2 inch. The functional split is egress: on the CL3372 the inside lever is always free, so it never traps an occupant, while an asylum function is keyed from both sides. Choose by whether the room requires free egress at all times.
17) Can I get the CL3372 in an antimicrobial finish for a healthcare or restroom application?
Yes. MicroShield antimicrobial coating is available on the CL3300 series using suffix option code C. Beyond that, finishes run from the common commercial 626 satin chrome and 613 oil rubbed bronze through brass and nickel options, plus BSP black suede and WSP white suede powder coat if you are matching painted trim rather than plated hardware.
18) Which Corbin Russwin lever design should I order, and does it change the lock?
Armstrong (AZD), Newport (NZD) and Princeton (PZD) are all solid cast levers on the same Grade 1 chassis, so the choice is appearance and feel, not function or strength. All are non-handed. Armstrong is the plainest institutional shape and the usual pick when standardizing a whole building; Newport and Princeton are more decorative for lobby and hospitality side openings. Keep one design across a property so spare parts and replacements interchange.
19) Do I need a handed lever lock, or is the Corbin Russwin CL3372 non-handed like the Falcon passage locks?
The CL3372 is non-handed, so one part number covers both left and right hand openings. The Falcon K101 Grade 1 passage lock and the Falcon B101 Grade 2 passage lever are also non-handed cylindrical designs. By contrast, the Baldwin Estate 5103 half dummy is ordered as a specific left hand or right hand part, so you have to determine the hand before you order those. If you are stocking a fleet of apartment doors, the non-handed CL3372 keeps a single SKU on the shelf.
