Corbin Russwin CL3352-KEYED Classroom Intruder Extra Heavy-Duty Cylindrical Lever Lock with Deadlocking Latchbolt

ANSI F110 Classroom Intruder Security — Double-Cylinder Control for Commercial & Institutional Applications

The Corbin Russwin CL3352-KEYED is an extra heavy-duty, Grade 1 cylindrical lever lock engineered specifically for classroom intruder security in demanding commercial, industrial, and institutional environments.

Corbin Russwin CL3352 NZD 626 – Frequently Asked Questions

1) What does the Corbin Russwin CL3352 classroom intruder function actually do at the door?
The CL3352 is an ANSI F110 classroom function lock, and the key detail is that the outside lever is locked and unlocked by turning a key in EITHER the inside or the outside lever. That means a teacher can lock the corridor side from inside the room without stepping into the hallway. The inside lever always retracts the latch, so egress is never blocked regardless of lock status. The latchbolt is deadlocking, so it can't be shimmed or carded once the door is closed.
2) Will a Corbin Russwin CL3352 fit my existing 1-3/4 inch classroom door prep?
Standard fit is 1-3/4 inch to 2 inch doors on a 2-3/4 inch backset, which is the normal commercial door and cylindrical lock prep. Corbin Russwin also offers the CL3352 for doors over 2 inch up to 2-1/4 inch, and with optional 3-3/4 inch and 5 inch backsets for wide-stile or unusual preps. It's non-handed, so there is no left/right to specify unless you go with FZD trim.
3) Can I get the CL3352 to work on my existing master key system?
Yes. Four cylinder choices are offered: the standard conventional 6-pin cylinder in the L4 keyway, LC (less conventional cylinder) if you are supplying your own, and CL6 or CL7 for less-core large format interchangeable core in 6-pin or 7-pin Corbin Russwin. If your facility is already on Corbin Russwin LFIC, order the CL6 or CL7 and drop in your own cores. If you're keying from scratch, the standard cylinder ships 0-bitted and can be ordered keyed alike or keyed different.
4) Is the CL3352 approved for a fire-rated classroom door?
It carries a fire rating and is UL-cUL listed, along with ANSI/BHMA A156.2 Grade 1, ANSI A117.1 accessibility compliance, and California State Fire Marshal listing. The lever operation and always-free inside lever satisfy the egress side of the requirement. For fire door assemblies calling for a 3/4 inch latch projection, order the optional 3/4 inch fire latch instead of the standard 1/2 inch.
5) What's the difference between the CL3352 and a plain classroom lock like the Cal-Royal AG03?
Function is the difference. A standard classroom lock is keyed only from the outside, so a teacher has to open the door and reach into the corridor to lock it. The CL3352 is the intruder version: the key works in both the inside and the outside lever, so the room can be secured from inside. The Cal-Royal AG03 is a Grade 2 classroom lever on a 2-3/4 inch backset with a 6-pin Schlage C keyway, which suits lighter traffic or where you are matching an existing Schlage C system. The CL3352 is Grade 1 extra heavy duty on the Corbin Russwin L4 keyway.
6) Would a storeroom lever work in place of the Corbin Russwin CL3352 on a classroom door?
They behave differently. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch; a storeroom outside lever stays locked at all times and is retracted by key. The CL3352 classroom function lets the outside lever be left unlocked or locked by key from either side, which is what a teacher needs to control the door during the day.
7) I'm standardizing a school on one lever. Which finishes and lever designs does the CL3352 come in?
Three cast lever designs are offered on the keyed CL3352: Armstrong (AZD), Newport (NZD) and Princeton (PZD). Finishes run to fourteen: 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. 626 satin chrome is the usual institutional default. Because the CL3300 Series covers passage, storeroom and other functions in the same lever and finish, you can match the whole building and change only the function.
8) Does the CL3352 hold up to students yanking on a locked lever?
That is what the Lever Release design addresses. When the outside lever is locked, it rotates freely instead of resisting, so force applied to the lever isn't transmitted into the chassis. The chassis itself is steel with a zinc dichromate treatment for corrosion resistance, and the lockset is rated ANSI/BHMA A156.2 Series 4000 Grade 1, extra heavy duty. Independent return springs keep the levers from sagging over time, which is the usual failure you see on lighter-grade levers in a school corridor.
9) Is there an electrified or access-control version of the Corbin Russwin CL3300 cylindrical lever?
The CL33900 is the electrified branch of the series, available fail safe or fail secure at 12 or 24 VAC/VDC, drawing 250mA at 12V and 150mA at 24V on a continuous duty solenoid. All electrified products use the ElectroLynx 8-pin connector, which saves you cutting and splicing at the transfer hinge. Pick fail safe where the opening must free on fire alarm, fail secure where it must stay locked. The mechanical CL3352 itself has no electrical option, so specify CL33900 up front if the door is going on access control.
10) Can I use the CL3352 on a healthcare or patient-area door instead of an asylum lock?
Only if you actually want key control from both sides with free inside egress. The CL3352's inside lever is always free, so it will not restrict movement out of the room. Where you need both levers key-controlled and no free operation from either side, that's an asylum function, and the Dexter C1000 Series Asylum (F87) is a Grade 1 cylindrical option for that. Corridor and staff doors that need lockdown from inside the room are where the CL3352 belongs. MicroShield antimicrobial coating is available on the CL3352 under option code C if the finish spec calls for it.
11) How does the CL3352 compare with the Dexter C1000 classroom security lever?
Both are Grade 1 cylindrical classroom-family levers. The Dexter C1000 Classroom Security model is listed for 1-3/8 inch to 1-3/4 inch doors and uses a clutching lever. The CL3352 covers 1-3/4 inch to 2 inch as standard with options past 2 inch, so if your doors are older 1-3/8 inch interior leaves the Dexter range reaches down and the Corbin Russwin does not. On the other hand, if you're already running Corbin Russwin LFIC cores across the facility, the CL3352 in CL6 or CL7 keeps one core standard through the building.
12) The door does not need to be keyed - what should I use instead of the Corbin Russwin CL3352?
For a non-keyed opening in the same heavy-duty class, the Falcon K101 is a Grade 1 heavy-duty passage cylindrical lock with non-handed levers, fire rated, for doors 1-3/8 inch to 2-1/4 inch, and the Falcon T101 is a Grade 1 heavy-duty passage lever with pressure release technology. Both leave the lever always free; the CL3352 is a keyed classroom lock whose outside lever is locked and unlocked by key.
13) What do I use on an office or entry door in the same building as the Corbin Russwin CL3352 classrooms?
For an entry or office opening the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever for doors 1-3/8 inch to 2 inch, and the Falcon B511CP6D is a Grade 2 medium-duty cylindrical lever with an entry/office function. The CL3352 is the Grade 1 classroom function for the teaching spaces; the entry/office locks add push-button or turn control at the door rather than key control of the outside lever from both sides.
14) Is there a keyless alternative to the Corbin Russwin CL3352 for a door where we do not want to issue keys?
The Lockey 2835 is a mechanical pushbutton keyless lever lock with a passage function and ADA compliance for doors 1-3/16 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those release the latch on a code rather than a key. The CL3352 is a keyed cylindrical lockset that accepts conventional 6-pin or 7-pin cylinders and all keying levels, which is what keeps it on a facility master key system.
15) We use Schlage C keyed hardware - how does that affect choosing the Corbin Russwin CL3352?
The CL3352 ships standard with a conventional 6-pin L4 keyway cylinder and can also be ordered less conventional cylinder or less core for 6-pin or 7-pin Corbin Russwin LFIC, so it can be brought onto an existing system. If the building is standardized on Schlage C, the Cal-Royal AG03 classroom lever and the Cal-Royal AG00 entrance lever are both supplied with a 6-pin Schlage C keyway keyed different.
16) I only need a non-keyed passage lever to match these classroom locks on the same corridor. What Grade 1 option works?
The CL3352 is a keyed classroom lock, so it is the wrong part for a door that just needs to push and pull. For Grade 1 non-keyed cylindrical passage on the same corridor, the Falcon K101 is a heavy duty Grade 1 passage lever, fire rated, fitting 1-3/8 to 2-1/4 inch doors, and the Falcon T101 and Design Hardware X75 are other Grade 1 passage options. For a door that only needs a pull with no latch at all, BEST 9K Series 1DT is a Grade 1 single dummy trim.
