Corbin Russwin CL3357-KEYED Extra Heavy-Duty Cylindrical Lever Lock | Storeroom/Closet Function, Grade 1, Non-Handed

Commercial-Grade Storeroom Security with Lever Release™ Vandal Resistance

The Corbin Russwin CL3357-KEYED is an extra heavy-duty, Grade 1 cylindrical lever lock engineered for storeroom and closet applications (ANSI function F86) in demanding commercial, industrial, and institutional environments. The deadlocking latchbolt is operated by key in the outside lever or by rotating the inside lever, with the outside lever freewheeling in the locked position while the inside lever remains always free. Designed for doors with a thickness range of 1-3/4" to 2" and a 2-3/4" backset, this lockset features a conventional 6-pin cylinder, two nickel silver keys, and an ANSI curved lip strike measuring 4-7/8" x 1-1/4" x 1-1/4" lip to center. The most common configuration is the NZD Newport lever in 626 Satin Chrome finish. The substrate is steel, zinc dichromated for corrosion resistance, and the product carries a Fire Rating and a 7 Year Limited Warranty.

Corbin Russwin CL3357 NZD 626 – Frequently Asked Questions

1) What does storeroom function actually do on the CL3357 lever lock?
The outside lever on the CL3357 is always locked. You get in with a key in the outside lever; the inside lever is always free, so anyone inside can walk out without a key or a thumbturn. There is no way to leave the outside lever unlocked, which is why this is the function specified for supply closets, mechanical rooms and IT rooms where the door must never be left open by accident. It is ANSI function F86.
2) Is the Corbin Russwin CL3357 handed, or do I need to specify left or right?
Non-handed. One CL3357 works on a left or right hand door with no field reversing, which means you can stock one part for a whole building and not sort them by opening. The only exception is FZD trim.
3) Can the CL3357 go on a fire rated door?
Yes, the CL3357 carries a fire rating and is UL-cUL listed. Note the standard latchbolt is stainless with a 1/2 inch throw; a 3/4 inch fire latch is available as an option, and on many rated openings that longer throw is what the frame prep and the door manufacturer's listing call for. Check which latch your opening was detailed for before you order.
4) Can I get the CL3357 to work on my existing Best or Schlage key system?
Yes, and this is the choice to get right on the order. Standard is a conventional 6-pin cylinder in the L4 keyway, 0-bitted. If your facility runs small format interchangeable core, order M08 (less core, SFIC prep, takes 6 or 7-pin cores of any design). For Schlage full size interchangeable core, order M69 less core. For Corbin Russwin large format IC, CL6 is 6-pin and CL7 is 7-pin, both less core. LC gives you the lock with no conventional cylinder at all so you can supply your own.
5) I need a run of storeroom locks all on one key. Can these be keyed alike?
Yes. The CL3357 can be ordered keyed different or keyed alike across multiple locks, and the chassis takes 6 or 7-pin conventional cylinders and all keying levels, so it drops into an existing master key system. It ships single cylinder with two nickel silver keys. If you need it pinned into a specific master system, put the system details in with the order.
6) What is the difference between the CL3357 and a Grade 2 storeroom lever like the Hager 2580 or Cal-Royal AG05?
All three are storeroom function, but the CL3357 is Grade 1 per ANSI/BHMA A156.2 Series 4000 with a steel, zinc dichromated chassis, and it takes 1-3/4 to 2 inch doors at a 2-3/4 inch backset. The Hager 2580 with the Withnell lever is Grade 2 storeroom and covers 1-3/8 to 2 inch doors; the Cal-Royal AG05 is Grade 2 storeroom with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors. If the opening is a thinner 1-3/8 inch door, the CL3357 will not fit and one of those two will. If it is high-traffic institutional work, Grade 1 is what gets specified.
7) I need a lock a classroom teacher can lock from inside during a lockdown. Is the CL3357 the right one?
No. The CL3357 is storeroom function, always locked outside with no way to lock or unlock it from the inside. For lockdown you want the CL3352 Classroom Intruder function in the same CL3300 Series, a double-cylinder lockset that lets the outside be locked by key from within the room while egress stays always free.
8) What is the closest Grade 1 storeroom-function cylindrical lever lock to the Corbin Russwin CL3357?
Within the commercial cylindrical lever locks carried alongside it, the CL3357 is the Grade 1 storeroom/closet unit, with a deadlocking latchbolt retracted by key in the outside lever or by rotating the inside lever, freewheeling outside lever when locked, and an always-free inside lever. The nearest storeroom-function peers are the Cal-Royal AG05 and the Hager 2580, both Grade 2 storeroom lever locksets. If the door schedule calls for Grade 1 specifically, the CL3357 is the one that meets it; if Grade 2 satisfies the spec, either of those two covers the same storeroom behavior.
9) Is the Cal-Royal AG05 storeroom lever a direct swap for a Corbin Russwin CL3357?
Not on every opening. The AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt, rated for doors 1-3/8 inch to 1-3/4 inch thick. The CL3357 is Grade 1 and covers 1-3/4 inch to 2 inch doors with a 2-3/4 inch backset. On a 1-3/4 inch door the two overlap; on a 2 inch door the AG05 is outside its stated thickness range, so the CL3357 is the one that fits.
10) The storeroom door does not need to be keyed - what Grade 1 lever lock covers a non-keyed opening instead of the CL3357?
The CL3357 is a keyed, single-cylinder storeroom/closet lock, so it is the wrong choice where nobody needs to lock the door. For a Grade 1 passage opening, the Falcon K101 is a heavy-duty non-keyed passage cylindrical lock with non-handed levers, fire rated, covering doors 1-3/8 inch to 2-1/4 inch. The Falcon T101 is another Grade 1 heavy-duty passage lever, and the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. Any of those latches the door without a key cylinder.
11) What Grade 1 cylindrical lever lock should be used instead of the CL3357 on a classroom door?
The CL3357 is storeroom/closet function: the outside lever is always locked and released by key, which is not how a classroom opening is usually specified. The Dexter C1000 Grade 1 classroom cylindrical lever lock is the classroom-function equivalent, with a clutching keyed lever for doors 1-3/8 inch to 1-3/4 inch, and the C1000 classroom security version adds the second cylinder arrangement. Corbin Russwin also builds the classroom intruder function as the CL3352 within the same CL3300 family, a double-cylinder lockset with always-free egress.
12) For an office door where the occupant needs to lock and unlock from the inside, is the CL3357 the right lock?
No - the CL3357 holds the outside lever locked at all times and releases it only by key, which suits a stockroom or closet rather than an office. Entry/office function is the one that lets the occupant secure the door themselves: the Dexter C1000 entry/office lever is Grade 1 for doors 1-3/8 inch to 1-3/4 inch, the Falcon B511CP6D is a Grade 2 medium duty entry/office lever, and the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors.
13) The storeroom needs code access rather than keys - what replaces a keyed lever lock like the CL3357?
Keypad leversets remove the key from the opening entirely. The Delaney LP250 is a Grade 2 electronic keypad leverlock, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination and a passage function covering doors 1-1/8 inch to 2 inch, and the Lockey 2835 is a mechanical pushbutton keyless lever lock, ADA compliant, for doors 1-3/16 inch to 2 inch. The CL3357 takes a conventional 6-pin L4 keyway cylinder and accepts 6 or 7-pin conventional cylinders and all keying levels, so it is the choice when the storeroom has to fall under an existing master key system.
14) If the storeroom lock has to accept an existing interchangeable core, is the CL3357 still the right lock?
Yes. Beyond the standard conventional 6-pin L4 keyway cylinder, the CL3357 can be ordered less core for Corbin Russwin LFIC in 6-pin or 7-pin, less core SFIC prep accepting 6 or 7-pin in all designs, less core FSIC for Schlage, or less conventional cylinder entirely. Among the comparable locks, the Cal-Royal AG05 storeroom and the Arrow MK33 asylum are built around conventional cylinders, and the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware rather than a lockset. For a facility standardized on interchangeable cores, ordering the CL3357 less core keeps it on the existing core system.
15) My door is thicker than 2 inches, or the backset in the door is 5 inches. Can I still use the CL3300 lever?
Yes, but you have to call it out. Standard is 1-3/4 or 2 inch doors at a 2-3/4 inch backset. Doors over 2 inches up to 2-1/4 inches are an option, and backsets of 3-3/4 inches and 5 inches are available as options for wide stile or full glass openings. Neither is what ships by default, so note it on the order.
16) Does the CL3357 storeroom lock have an ADA compliant lever?
The CL3357 is a lever, not a knob, and it is listed to ANSI A117.1 Accessibility. Levers are what accessibility requirements call for on the pull side because they operate without tight grasping or twisting of the wrist, which is why knob-style locks get replaced on these openings.
17) Which lever designs and finishes does the Corbin Russwin CL3357 come in?
Three lever designs on the CL3357: AZD Armstrong, NZD Newport, and PZD Princeton, all solid cast with independent return springs so the lever does not sag over time. Finishes run 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. NZD Newport in 626 satin chrome is the common commercial pick and the one most likely to match existing openings in an office or school.
18) What happens if someone yanks or kicks the locked lever on a storeroom door?
The outside lever on the CL3357 freewheels when locked, which is the Lever Release design. Force applied to the outside lever spins it rather than transmitting into the chassis, so the common vandalism failure on institutional storeroom doors does not break the lock. It also has anti-rotational through-bolts at the 6 and 12 o'clock positions to keep the trim from turning on the door.
19) Can a storeroom lock be released from a card reader or access control panel?
Not the mechanical CL3357. For access control you want the CL33900 electrified version of the CL3300 Series, which comes fail safe or fail secure and runs on 12 or 24VAC/VDC, drawing 250mA at 12V and 150mA at 24V through a continuous duty solenoid. It uses an ElectroLynx 8-pin connector, so it plugs into an ElectroLynx electric hinge or power transfer instead of being hard wired. Decide fail safe versus fail secure by whether the door must unlock or stay locked when power drops.
20) Do I need a rounded corner latch instead of a square one on a metal door?
Yes, if the door was prepped that way. The CL3357 ships with the 586F17 square corner deadlatch, 2-1/4 x 1-1/8 inches at a 2-3/4 inch backset. The 596F67 rounded corner deadlatch at the same size and backset is the alternative and is what most hollow metal doors with a factory routed edge prep need. Look at the existing latch face before you order, since the wrong corner means chiseling the door edge.
21) I only need a passage or dummy lever to match my Corbin Russwin storeroom doors. What do I use?
The CL3357 is keyed storeroom function only, so it is the wrong part for a door that just needs to latch or for a pull-side trim. For a Grade 1 passage lever, the BEST 9K Series and the Falcon K101 and T101 are heavy duty Grade 1 non-keyed options, with the K101 covering 1-3/8 to 2-1/4 inch doors and carrying a fire rating. For a single dummy trim, the BEST 9K Series 1DT is the Grade 1 choice. The lever design will not match the Corbin Russwin Newport or Armstrong profile, so on a run of visible openings that matters.
22) Is a keypad lever a workable substitute for a keyed storeroom lock on a supply room?
Different trade-off. The CL3357 is Grade 1, keyed, storeroom function with a deadlocking latchbolt, and it ties into an existing master key system. The Lockey 2835 and 1150 mechanical keypad lever sets are keyless and passage function, so the latch is not held locked against a credential the way a storeroom lock is; the 1150 fits 1-1/8 to 2 inch doors and the 2835 fits 1 3/16 to 2 inch. If the requirement is code entry with no keys issued, a keypad is the answer. If the requirement is a locked storeroom on the building master, it is not.
23) Does the auxiliary latch on the CL3357 stop someone from carding the door open?
Yes. The CL3357 uses a deadlocking auxiliary latchbolt that depresses against the strike when the door closes and blocks the main latchbolt from being pushed back, so a shim or a card in the gap will not retract it. That is the feature that makes this suitable as the sole lock on a storeroom or IT closet rather than needing a separate deadbolt.
24) Will a BEST 9K dummy trim work as a replacement for a Corbin Russwin CL3357?
No. The BEST 9K 1DT is Grade 1 heavy duty dummy trim - a non-keyed, non-latching lever used as a pull on an inactive leaf. The CL3357 is a keyed storeroom/closet lockset with a deadlocking latchbolt and a conventional 6-pin cylinder. Dummy trim matches the lever appearance but secures nothing; use it only on the inactive leaf of a pair and keep the CL3357 on the leaf that actually latches.
25) Can a Kwikset or Callan lever be used on a commercial storeroom door in place of the CL3357?
They are built to a different duty level. The Kwikset 200BRNL Breton passage lever and the 300BRNL Breton privacy lever are Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and Callan units such as the Artino entrance and Asheville passage leversets are Grade 3 as well. The CL3357 is a Grade 1 commercial storeroom lock, fire rated, on a steel chassis that is zinc dichromated for corrosion resistance. On a storeroom in a school, hospital, or warehouse the Grade 1 keyed unit is the one written into the specification.
26) What goes on a utility or patient room door where a storeroom lock like the CL3357 is not the right function?
Asylum or institutional function is the one specified where the door must be key operated from both sides. The Dexter C1000 asylum lock is Grade 1, ANSI F87, for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a heavy duty asylum knob lock with a conventional Schlage C keyway cylinder. The CL3357 is ANSI F86 storeroom, single cylinder, with the inside lever always free, so it always allows egress rather than restricting it.
27) Is there an antimicrobial option for the lever in a healthcare setting?
Yes, the CL3300 Series levers are available with MicroShield antimicrobial coating, ordered with the suffix option code C. Worth specifying on patient room, clinic and food service openings where touched surfaces are part of the infection control plan.
28) Does the CL3357 hold up in a damp or corrosive environment like a mechanical room or coastal building?
The lock chassis is steel, zinc dichromated for corrosion resistance, and the latchbolt is stainless steel. That is the construction specified for mechanical rooms, warehouses and industrial storerooms. Finish selection still matters for exterior exposure; the plated brass finishes will weather differently than 626 satin chrome.
29) Can a Baldwin Estate 5103 or Emtek leverset be used on the same doors as a Corbin Russwin CL3357?
They serve different openings. The Baldwin Estate 5103 comes in passage, privacy, and half dummy versions with the 5048 rose, and the Emtek Arts and Crafts and Classic Brass leversets are sold as dummy pairs. None of those is a keyed storeroom lock. The CL3357 is a keyed, non-handed Grade 1 storeroom/closet lockset with a deadlocking latchbolt for commercial doors. Decorative leversets suit interior residential-style openings; the storeroom itself needs the keyed commercial unit.
30) What Grade 2 lever lock covers the non-secured doors on the same corridor as a CL3357 storeroom?
For the passage doors around a storeroom, the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever, the Arrow GL01 is a Grade 2 passage cylindrical lock with the Sierra lever for doors 1-3/4 inch to 2 inch, and the Hager 2510 is a Grade 2 passage lever with the Withnell design for 1-3/8 inch to 2 inch doors. The CL3357 stays on the door that has to be locked, since it is the keyed Grade 1 storeroom unit with a deadlocking latchbolt.
