Corbin Russwin CL3359 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CL3359 storeroom lever fit a 1-3/4 inch commercial door with a 2-3/4 inch backset?
That's exactly the opening it's built for. The CL3359 covers door thicknesses of 1-3/4 inch to 2 inch with a 2-3/4 inch backset as standard, which is the usual commercial hollow metal or solid core setup. It ships non-handed, so you don't specify left or right, and the standard deadlatch has a square corner front measuring 2-1/4 x 1-1/8 inches. If your doors run thicker than 2 inches, or your existing prep is a 3-3/4 inch or 5 inch backset, those are available as options rather than the stock build.
2) How does a storeroom function lock actually work day to day on a public restroom door?
The outside lever stays locked at all times. A key retracts the latch and unlocks the outside lever, and the key is retained while it's in unlock mode, so nobody walks off leaving the door unsecured by accident. Pull the key and the outside lever locks again on its own. The inside lever is always free, so anyone inside can get out without a key, which is what you want on a restroom or storeroom. There is no thumbturn and no pushbutton to set, which is why facilities pick this function over an entry/office lock: staff cannot leave it unlocked.
3) Is the Corbin Russwin CL3359 approved for a fire rated door opening?
Fire rated, yes, and it carries UL-cUL listing along with ANSI/BHMA A156.2 Grade 1, ANSI A117.1 accessibility, and California State Fire Marshal listing. One ordering detail matters on a fire door: the stock latch has a 1/2 inch throw, and a 3/4 inch fire latch is offered as an option. Check what your door and frame gap actually requires before you place the order.
4) Can I get the CL3359 to work on my existing small format interchangeable core master key system?
Yes, and the cylinder choice is made at order time. Standard build is a conventional 6-pin brass cylinder in the L4 keyway, 0-bitted. If you're on an SFIC system, order it with M08, which is the less-core SFIC prep and takes 6 or 7-pin cores in all designs. For Corbin Russwin large format IC there's CL6 for 6-pin and CL7 for 7-pin, both supplied less core. M69 is less core FSIC for a Schlage system. LC gets you the lock less conventional cylinder if you're supplying your own. The chassis accepts all keying levels, so grand master and construction keying are both on the table.
5) Is the Cal-Royal AG05 or Hager 2580 storeroom lever a drop-in for a 2 inch thick door?
Door thickness decides this one. The Corbin Russwin CL3359 covers 1-3/4 inch to 2 inch doors as standard. The Cal-Royal AG05 storeroom lever lists a 1-3/8 inch to 1-3/4 inch door thickness range, so it stops short of a 2 inch leaf. The Hager 2580 Withnell storeroom lock lists 1-3/8 inch to 2 inch, which does reach 2 inch. On a heavy 2 inch institutional door, the CL3359 and the Hager 2580 are the two storeroom options whose published thickness range covers it.
6) The door does not need to lock at all - what should I use instead of a CL3359?
A storeroom function keys the outside lever, which is wasted on a corridor or closet door that only needs a latch. For a Grade 1 passage lever in the same heavy-duty commercial tier, the Falcon K101 is a Grade 1 passage cylindrical lock with non-handed levers covering 1-3/8 inch to 2-1/4 inch doors, and the Falcon T101 is a Grade 1 heavy-duty passage lever. The Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. Stepping down in grade, the Accentra 5301LN Augusta and the Arrow GL01 Sierra are Grade 2 passage levers. The CL3359 stays on openings that need the key.
7) Storeroom or classroom function for a school corridor door?
They behave differently at the door. The Corbin Russwin CL3359 storeroom function keeps the outside lever locked whenever the key is out, so the opening is secure by default and staff key in. A classroom function leaves the outside lever unlocked between key turns so the room stays open during class. For classroom openings, the Dexter C1000 is a Grade 1 classroom cylindrical lever lock with clutching levers, and the Dexter C1000 classroom security version is a Grade 1 classroom security lock. The Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset. Match the CL3359 to storerooms, mechanical rooms and public restrooms, and a classroom function to the teaching spaces.
8) Can I use an entry/office lock on a storeroom instead of the CL3359?
Entry/office and storeroom are not interchangeable. The CL3359 has no inside pushbutton or thumbturn - the only way the outside lever unlocks is a key, and it relocks when the key comes out. An entry/office function lets an occupant lock or unlock the outside lever from the inside, which is what you want on an office and what defeats the point on a stockroom. The Grade 1 entry/office peer is the Dexter C1000 entry/office cylindrical lever with clutching levers, and Grade 2 options include the Falcon B511CP6D entry/office lever and the Hager 2525 commercial entry lock. Use those where the occupant should control the door, and the CL3359 where only the keyholder should.
9) What keeps the outside lever from being snapped off when someone yanks on a locked restroom door?
When it's locked, the outside lever on the CL3359 freewheels instead of resisting. Force applied to the lever spins it rather than loading the chassis, so the lock mechanism isn't what absorbs the abuse. That is the reason this lock ends up on public restrooms and storerooms in schools and transit buildings. It's a Grade 1 extra heavy duty chassis, steel with a zinc dichromated finish for corrosion resistance, and independent return springs on each side keep the levers from sagging over time.
10) I'm ordering a dozen storeroom locks for one building. Do I have to specify keyed alike or keyed different?
Keying is a required selection on the CL3359, and there are two: KD keyed different, so every lock has its own key, or KA keyed alike, so one key runs the whole group. Storerooms in one facility are usually keyed alike, restrooms often keyed different by floor or tenant. There's a free text field for special cylinder or keying requirements if you're pinning into an existing system and need it done to a specific bitting or keyway.
11) What lever styles and finishes does the Corbin Russwin CL3359 come in, and will they match the other doors in the building?
Three lever designs on the CL3359: Armstrong (AZD), Newport (NZD) and Princeton (PZD), all solid cast. Finishes run to fourteen: bright and satin brass (605, 606), bright and satin bronze (611, 612), oil-rubbed satin bronze (613) plus the 613E and 613L dark oxidized variants, black oxidized bronze oil-rubbed (722), bright and satin nickel (618, 619), bright and satin chrome (625, 626), and two powder coats, Black Suede (BSP) and White Suede (WSP). If you're standardizing a facility, 626 satin chrome is the usual commercial default. Note that the same lever and finish combinations are used across the CL3300 Series, so passage and classroom functions on other doors can be matched to these.
12) Should I use a storeroom lock or a classroom lock on this door?
Different problems. Storeroom, which is what the CL3359 is, keeps the outside lever locked permanently and only a key gets you in, with free egress inside. Nobody can leave it unlocked. A classroom function is meant for a room that gets unlocked for periods of the day. If you specifically need lockdown from inside the room, Corbin Russwin's CL3352 classroom intruder function on the same CL3300 platform is a double-cylinder lockset with always-free egress, keyed from either side. For a straight keyed office door where staff want to secure it as they leave, neither of these is right and an entry/office function is the one to spec.
13) Is there a Grade 1 storeroom lever alternative to Corbin Russwin, or a cheaper Grade 2 one?
Within Grade 1 cylindrical levers there's the Dexter C1000 Series, which covers 1-3/8 inch to 2 inch doors in its asylum function and 1-3/8 inch to 1-3/4 inch in its classroom, classroom security and entry/office functions, though those are different functions rather than a straight storeroom swap. For a lighter-duty storeroom on an interior door where Grade 1 isn't required by spec, the Hager 2580 with Withnell lever is a Grade 2 storeroom lock fitting 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch. On a high-traffic public restroom or a fire rated opening, the Grade 1 CL3359 is the one that holds up.
14) Can I get this Corbin Russwin storeroom lock electrified for access control?
Not this model directly. The CL3359 is a mechanical, key-operated lockset. For access control on the same CL3300 platform, the CL33900 electrified series is the one to order: fail safe or fail secure, 12 or 24VAC/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 field-wiring the connection at the hinge. You'll need a power transfer and a power supply sized to those figures.
15) What should I put on a patient room or holding room door instead of a storeroom lever?
Asylum function is the one to look at. The Corbin Russwin CL3359 keeps the inside lever always free for egress, which is correct for a storeroom or restroom but wrong for a room where the inside must also be controlled. The Dexter C1000 asylum is a Grade 1 asylum/institution/utility cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy-duty asylum cylindrical lock with a ball knob and a conventional Schlage C keyway cylinder. Both key both sides. Where free egress is required by code, the CL3359 is the correct choice.
16) I want keyless entry on a storeroom door - what replaces the CL3359?
A mechanical or electronic keypad leverset removes the key from the equation. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the 2835DC adds a second combination. The Lockey 1150 is a heavy-duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors, with an adjustable-backset version. On the electronic side, the Delaney LP250 is a Grade 2 electronic keypad leverlock. The CL3359 is the conventional-cylinder route: a 6-pin L4 keyway cylinder as standard, with less-core variants for LFIC, SFIC and Schlage FSIC cores if the facility is already on a key system.
17) Does the Accentra 107S adapter let me put a Schlage cylinder in a CL3359?
No - it is built for a different lock. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, so it addresses Yale-brand locksets rather than the Corbin Russwin CL3300 platform. On the CL3359, cylinder compatibility is handled at the lockset itself: it ships with a conventional 6-pin L4 keyway cylinder, and it can be ordered less core for Corbin Russwin LFIC in 6 or 7-pin, SFIC prep accepting 6 or 7-pin cores in all designs, or Schlage FSIC. If the building keys on Schlage cores, the M69 less-core FSIC option is the route, not an adapter kit.
18) Will a Baldwin or Emtek lever match the CL3359 on adjoining doors?
They serve different jobs on the opening. The Baldwin Estate 5103 with 5048 rose comes as a passage lever, a privacy lever, and left or right hand half dummies - none of which is a keyed storeroom function. Emtek Arts and Crafts and Classic Cortina leversets in the set are dummy pairs. The Corbin Russwin CL3359 is the keyed storeroom device, non-handed, in a 14-finish range including 626 satin chrome, 613 satin bronze oil-rubbed and 605 bright brass, with Armstrong, Newport and Princeton lever designs. Pair the CL3359 on the secured openings and use the decorative passage, privacy or dummy levers where nothing has to lock.
19) What is the inactive-leaf or pull-side match for a CL3359 opening?
A dummy trim gives the same lever look on a leaf that has no latch. The BEST 9K Series 1DT is a Grade 1 heavy-duty single dummy trim cylindrical lever, and the BEST 7KC Series 1DT is a Grade 2 medium-duty single dummy trim lever. The Accentra 455LN Augusta is a Grade 1 heavy-duty single dummy cylindrical lever. None of these latch or key - the Corbin Russwin CL3359 is the keyed, deadlocking-latchbolt half of that pairing on the active leaf.
20) Can a residential Grade 3 lever go on a public restroom door instead of the CL3359?
The traffic level is the deciding factor. The Corbin Russwin CL3359 is a commercial Grade 1 heavy-duty cylindrical lever built on a steel, zinc dichromated chassis for corrosion resistance, with a storeroom/public restroom function. The Grade 3 levers in the set are built for lighter service: the Cal-Royal AUS00 entrance/office lever for 1-3/8 inch to 1-3/4 inch doors, the Callan Artino and Bennett entrance leversets, the Kwikset 200BRNL Breton passage and 300BRNL Breton privacy sets for 1-3/8 inch to 1-3/4 inch doors, and the Master Lock RL Series keyed entry lever. Those suit interior residential openings; a public restroom in a school or arena is what the CL3359 is graded for.
21) For a single-occupancy restroom, do I need the CL3359 or a privacy lock?
It depends on who controls the door. A privacy function locks from inside for the occupant: the Arrow MK02-TA is a fire-rated privacy cylindrical lock with a Tudor knob for 1-3/4 inch to 2 inch doors, and the Baldwin Estate 5103 is offered as a privacy lever. The Corbin Russwin CL3359 is the public restroom answer instead - the outside lever is locked and keyed by staff while the inside lever stays always free, so the room is controlled by the facility rather than the user. Multi-stall public restrooms and janitor closets take the CL3359; a single-occupancy restroom where the user needs to lock themselves in takes a privacy function.
22) Is there a lighter-duty storeroom lever if Grade 1 is more than the opening needs?
Yes. The Hager 2580 with the Withnell lever is a Grade 2 storeroom cylindrical lock for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. Both give the storeroom behavior at Grade 2. The Corbin Russwin CL3359 is the Grade 1 heavy-duty version of the same function, non-handed, on a 2-3/4 inch backset with a deadlatch and ANSI curved lip strike. On a low-traffic supply closet the Grade 2 levers cover the function; on a high-traffic or spec-driven opening the grade is the reason to stay with the CL3359.
23) Which storeroom lever works on a 2-3/4 inch backset door prep?
The Corbin Russwin CL3359 is a 2-3/4 inch backset lockset as standard, so it drops into a standard commercial bore without redrilling. Among the peers, the Cal-Royal AG03 classroom lever is also a 2-3/4 inch backset device, while the Cal-Royal AG00 entrance lever is a 2-3/8 inch backset. Backset is the first thing to confirm against the existing prep - a 2-3/8 inch device will not line up on a door bored at 2-3/4 inch.
24) Is there an antimicrobial option for a healthcare or restroom lever?
MicroShield antimicrobial coating is offered on the CL3300 Series under option code C. It's a coating on the lever and trim, which is where hands actually make contact. Healthcare and food service facilities usually spec it on public restroom and corridor doors. It's ordered as a suffix, not a separate model, so the CL3359 storeroom function, lever design and finish selection all stay the same.
25) What holds the CL3359 to the door, and does it need through-bolting?
It uses anti-rotational through-bolts at the 6 and 12 o'clock positions, so the trim is fixed through the door rather than just screwed to a rose. That's what stops the whole assembly turning on the door after a few years of abuse, which is the usual failure on lighter cylindrical locks in high-traffic openings. Corbin Russwin's EZ-Install components cut the install time down; a standard 2-3/4 inch backset cylindrical prep, which is the common commercial bore, is all the door needs.
26) Is a lever trim like the Imperial ED-EL500HD an alternative to the CL3359?
They mount to different things. The Imperial USA ED-EL500HD is heavy-duty escutcheon lever trim with an entry function from the ED-500 exit device series - it is trim that hangs on an exit device, so it needs that device on the door. The Corbin Russwin CL3359 is a complete cylindrical lockset: chassis, deadlocking latchbolt, ANSI curved lip strike and cylinder, bored straight into the door. If the opening already has a rim or mortise exit device, you are shopping trim; if it is a plain bored door, the CL3359 is the whole assembly.
