Corbin Russwin CLX3357 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CLX3357 storeroom lever fit a 1-3/4 inch commercial door?
Yes. The CLX3357 is built for doors 1-3/4 inch to 2 inch thick with a 2-3/4 inch backset, which is the standard commercial door and the standard commercial backset. It's non-handed, so one lock covers both left and right swings on a run of storeroom doors.
2) How does a storeroom function lock actually work day to day?
On the CLX3357 the outside lever is always locked and takes a key to retract the deadlocking latchbolt. The inside lever is always free, so anyone inside gets out without a key or a thumbturn. You cannot leave it unlocked, which is the point on a storeroom or supply closet: the door secures itself every time it shuts. In the locked state the outside lever freewheels rather than resisting, so someone hanging on it isn't loading the chassis. It's ANSI function F86.
3) Can the CLX3357 go on a fire rated storeroom door?
It's fire rated and carries a UL/cUL 3-hour rating and meets NFPA 80, so it can go on a rated storeroom or stairwell-side opening. Door prep is to ANSI/SDI A250.14. Also ADA A117.1 compliant, which the lever trim is what earns.
4) Do I need to order a cylinder separately with the CLX3357, or can I put it on my building's existing key system?
The standard build ships with a conventional 6-pin brass cylinder in the L4 keyway, 0-bitted. If your facility is already on an interchangeable core system, order it less core instead: CL6 or CL7 for Corbin Russwin large format 6- or 7-pin, M08 for SFIC prep that takes any 6- or 7-pin small format core, or M69 for Schlage full size IC. LC gets you the lock less conventional cylinder. That covers most existing masterkey systems without changing the chassis.
5) Will the CLX3357 latch reuse the strike already in my frame?
The lock comes with an ANSI curved lip strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center, and a deadlatch with a square corner front measuring 2-1/4 x 1-1/8 inches at 2-3/4 inch backset. Latchbolt throw is 1/2 inch standard. If your frame already has the standard 4-7/8 inch ANSI strike cutout, it drops in. On a rated opening needing more throw there's an optional 3/4 inch deadlocking fire latch.
6) Can I key a group of CLX3357 storeroom locks alike so one key opens every closet?
Yes, keyed alike is an ordering choice on the CLX3357: pick KA for a set of locks that share one key, or KD keyed different if each door needs its own. It's a single cylinder lock, keyed outside only. There's also a free text field for special keying instructions if you're matching an existing masterkey system or bitting.
7) Will this lever fit a narrow aluminum stile door?
Minimum stile for the CLX3357 is 4-1/2 inches. Anything narrower than that, this cylindrical chassis will not fit and you need a narrow stile device instead. That rules out most storefront aluminum stiles, which typically run narrower.
8) What if my storeroom doors are 1-3/8 inch or thicker than 2 inches?
The standard CLX3357 covers 1-3/4 to 2 inch doors. For a thinner 1-3/8 inch door order the D138 option, and for doors over 2 inch up to 2-1/4 inch order D214. Backset options besides the 2-3/4 inch standard are 2-3/8 inch, 3-3/4 inch and 5 inch, which is what you want on a door with an unusual bore location or a wide rail. A patented push/turn button handles the thickness adjustment during install.
9) What is the closest Grade 1 storeroom lever lock to the Corbin Russwin CLX3357 if I need a different brand?
Within the commercial cylindrical lever locks carried alongside the CLX3357, the closest same-grade storeroom peer is not an exact match on function. The CLX3357 is a Grade 1 storeroom/closet cylindrical lever with a deadlocking latchbolt operated by key in the outside lever or by rotating the inside lever, with the outside lever freewheeling when locked. The Hager 2580 is also a storeroom function cylindrical lock with the Withnell lever, but it is Grade 2 and fits doors 1-3/8 inch to 2 inch, where the CLX3357 fits 1-3/4 inch to 2 inch. The Cal-Royal AG05 is likewise storeroom function with a deadlocking latchbolt at Grade 2, for doors 1-3/8 inch to 1-3/4 inch. If Grade 1 is on the spec, stay with the CLX3357; if the opening allows Grade 2, the Hager 2580 and Cal-Royal AG05 hold the same storeroom function.
10) My door is 1-3/8 inch thick - what storeroom lever works there instead of the CLX3357?
The CLX3357 in its standard build covers doors 1-3/4 inch to 2 inch. For a 1-3/8 inch door, the Cal-Royal AG05 Grade 2 storeroom lever lockset with a deadlocking latchbolt covers 1-3/8 inch to 1-3/4 inch, and the Hager 2580 storeroom lock with the Withnell lever covers 1-3/8 inch to 2 inch. Both keep the storeroom function - locked outside lever, key entry, free egress inside - on the thinner door.
11) The opening is a classroom, not a storeroom - what Grade 1 lever should I order?
The CLX3357 is a storeroom/closet function lock: the outside lever is always locked and released only by key. A classroom opening needs the outside lever keyed to lock and unlock, which is a different function. The Dexter C1000 Series classroom lever lock is Grade 1, keyed, with a clutching lever for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom security version is Grade 1 keyed for the same door range. Cal-Royal also builds the AG03 classroom lever in the AG Series with a 6-pin Schlage C keyway keyed different on a 2-3/4 inch backset, which matches the 2-3/4 inch backset the CLX3357 uses as standard.
12) I want an office door where staff can leave the outside lever unlocked during the day - is the CLX3357 the right lock?
No. The CLX3357 keeps the outside lever locked at all times and opens only by key, which is the storeroom function. For an office that gets unlocked in the morning and locked at night, use an entry/office function: the Dexter C1000 Series entry/office cylindrical lever is Grade 1, keyed, with a clutching lever for doors 1-3/8 inch to 1-3/4 inch. At Grade 2 there is the Falcon B511CP6D entry/office cylindrical lever and the Hager 2525 commercial cylindrical entry lock for doors 1-3/8 inch to 2 inch.
13) The door is a utility or patient room that needs to lock from both sides - is the CLX3357 correct?
No. The CLX3357 leaves the inside lever always free for egress, which is what makes it a storeroom lock. An asylum or institutional function locks both levers and requires a key on each side. The Dexter C1000 Series asylum lock is Grade 1, ANSI function F87, for doors 1-3/8 inch to 2 inch. The Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and a conventional Schlage C keyway cylinder. Confirm the egress code for the room type before specifying a both-sides-locked function.
14) We key everything to Schlage C - does that rule out the Corbin Russwin CLX3357?
It does not. The CLX3357 chassis is offered less core for several core formats, including M69 less core FSIC for Schlage, M08 less core SFIC prep that accepts 6 or 7 pin cores in all designs, and CL6 or CL7 less core LFIC for Corbin Russwin, alongside the standard conventional 6-pin L4 keyway cylinder and LC less conventional cylinder. If instead you want a lock that arrives already cut to Schlage C, the Cal-Royal AG03 classroom lever and the Cal-Royal AG00 entrance lever both use a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock uses a conventional Schlage C keyway cylinder - though those are different lock functions, not storeroom.
15) Is a Grade 1 cylindrical lever worth it over a Grade 2 storeroom lock for a back-of-house door?
Depends on the traffic and the abuse. The CLX3357 is ANSI/BHMA A156.2 (2022) Series 4000 Grade 1, UL cycle tested to 20 million cycles, and holds past 3,100 in-lb of abusive locked lever torque and 1,600 lbs of offset lever pull. That's the spec for a high traffic or public-facing opening where people hang on the lever. For a low traffic interior supply closet, a Grade 2 storeroom lever such as the Hager 2580 with the Withnell lever or the Cal-Royal AG05 with a deadlocking latchbolt does the same function at a lighter duty rating.
16) What Grade 1 storeroom alternatives are there if the CLX3357 doesn't suit the door?
On thinner doors the Dexter C1000 Series Grade 1 cylindrical levers run 1-3/8 to 1-3/4 inch, and the Falcon K101 Grade 1 fire rated lever covers 1-3/8 to 2-1/4 inch, though the K101 is passage function and won't secure a storeroom. Watch the function, not just the grade: several Grade 1 cylindrical levers people compare against this one, including the BEST 9K 1DT, are dummy trim with no latch at all.
17) Can I match the CLX3357 to the lever style and finish on the rest of my building's doors?
Three lever designs are offered, Armstrong (AZD), Newport (NZD) and Princeton (PZD), across fourteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 613E and 613L dark oxidized bronze, 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. The common commercial spec is NZD Newport in 626 satin chrome.
18) Can the CLX3357 be swapped to a classroom or electrified function later on the same door prep?
The CLX3300 platform runs 27 mechanical and 2 electrified functions off the same chassis, so a door prepped for the CLX3357 storeroom can take another function in the family later. That includes the CLX3352 classroom intruder, which locks from either side and keeps egress always free. Electrified versions use an ElectroLynx 8-pin molex connector, run 12VDC or 24VDC at 10mA continuous with a 500mA peak, and are UL294 listed.
19) Can I use a passage lever on the closet door instead of the keyed CLX3357?
If the closet does not need to be secured, a passage lever is the simpler build - it latches but never locks, so there is no cylinder and no key to manage. The CLX3357 is keyed with a conventional 6-pin L4 keyway cylinder. Grade 1 passage peers include the Falcon K101 non-handed passage cylindrical lock, fire rated, for doors 1-3/8 inch to 2-1/4 inch, the Falcon T101 heavy duty passage lever, and the Design Hardware X75 passage lever lockset with a flat lever for 1-3/4 inch doors. Choose passage only where the closet contents do not require key control - the CLX3357 exists for the ones that do.
20) Is the Accentra 5301LN Augusta an alternative to the CLX3357?
It is not a substitute. The Accentra 5301LN Augusta is a Grade 2 cylindrical lever in the 5300 Series with passage/hall/closet function, so it has no cylinder and no locking. The CLX3357 is Grade 1 and keyed, with a single cylinder storeroom function - the outside lever stays locked and is released by key. The two look similar as cylindrical levers but they do opposite jobs at the opening.
21) What do I order to match the CLX3357 on a door leaf that does not latch, like an inactive or closet dummy?
A dummy trim is the correct part there - it is a lever on a rose with no latch and no chassis, so it will not accept a key. The CLX3357 by contrast is a 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. For the non-latching leaf, the BEST 9K Series 1DT single dummy trim cylindrical lever is Grade 1 heavy duty, and the BEST 7KC Series single dummy trim is Grade 2 medium duty. The Accentra 455LN Augusta is a Grade 1 heavy duty single dummy in the 5400 Series.
22) I want to get rid of keys on the storeroom door - what keyless lever replaces the CLX3357?
The CLX3357 is a keyed cylindrical lock that ships with a conventional 6-pin L4 keyway cylinder. If the goal is code entry instead of key control, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and Lockey builds mechanical pushbutton lever locks with no batteries or wiring - the 2835 single combination and the 2835DC double combination for doors 1-3/16 inch to 2 inch, and the 1150 heavy duty keypad lever set for doors 1-1/8 inch to 2 inch. Note those Lockey units are passage function, so they release the latch on a code rather than holding a storeroom function with a deadlocking latchbolt.
23) I need the storeroom lock on a restroom or bedroom door - what should I use instead?
A storeroom lock is the wrong function for a restroom or bedroom. The CLX3357 requires a key on the outside at all times and has no inside locking button, since the inside lever is always free. Use a privacy function instead: the Arrow MK02-TA is a privacy bed/bath cylindrical lock with a Tudor knob, non-keyed, fire rated, for doors 1-3/4 inch to 2 inch. Hager builds the 2540 privacy cylindrical lock with the Withnell lever, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever for doors 1-3/8 inch to 1-3/4 inch.
24) Will the Accentra 107S adapter let me put a Schlage cylinder in the CLX3357?
No. The Accentra 107S is a Schlage cylinder adapter kit made for Yale hardware, so it is not a part for a Corbin Russwin chassis. To run a Schlage format core in the CLX3357, order the chassis with the M69 less core FSIC Schlage option, which is a factory cylinder configuration on the lock itself rather than an adapter added later.
25) The architect specified a decorative brass lever for the corridor - can a Baldwin or Emtek lever do the storeroom door too?
Not the same door. The Baldwin Estate 5103 with the 5048 rose is built in passage, privacy, and half dummy versions in left and right hand, and Emtek Classic Brass Cortina and Arts and Crafts levers are sold as dummy pairs - none of those hold a keyed storeroom function. The CLX3357 is the keyed storeroom lock and it is non-handed, so it drops into either swing. It is also offered in 605 Bright Brass, 606 Satin Brass, 611 Bright Bronze, and 612 Satin Bronze among its finishes, with Armstrong, Newport, and Princeton lever designs, if the goal is to keep the secured door visually close to decorative trim elsewhere.
26) Can I put a residential-grade lever on a commercial storeroom door to save a step?
The grade tier is the deciding factor. The CLX3357 is a commercial lock certified Grade 1. The Kwikset 200BRNL Breton passage lever and 200DL Delta passage lever are Grade 3 residential-style interior hall and closet locks, the Master Lock BC Series RL01 is a Grade 3 keyed entry lever, and Cal-Royal AUS00 and Callan Artino are Grade 3 entrance levers. Grade 3 units are built for interior and residential duty and do not carry a Grade 1 storeroom certification, so they will not answer a commercial spec that calls for one.
27) I need a fire rated lever for a labeled opening - which options besides the CLX3357 carry a fire rating?
The CLX3357 is fire rated and is a keyed Grade 1 storeroom lock, which is the usual choice on a labeled storeroom door. Among the peer cylindrical locks, the Falcon K101 Grade 1 passage lock is fire rated for doors 1-3/8 inch to 2-1/4 inch, and the Arrow MK02-TA privacy lock with Tudor knob is fire rated for doors 1-3/4 inch to 2 inch. Those two are passage and privacy functions, so they suit a labeled opening only where no key control is required.
28) What is the difference between the CLX3357 and a knob-style commercial lock like the Arrow HK11?
Trim type and function both differ. The CLX3357 uses a lever handle, which is what ADA-governed openings generally require, and it is a non-handed Grade 1 storeroom lock for doors 1-3/4 inch to 2 inch. The Arrow HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and a conventional cylinder in the RL Series, Grade 2, for doors 1-3/8 inch to 1-3/4 inch. A turn-button entrance function can be left unlocked by the occupant; the storeroom function of the CLX3357 cannot.
29) Will the CLX3357 hold up in a coastal or damp mechanical room?
The lock body is steel with a zinc dichromate treatment for corrosion resistance, and the latchbolt is stainless steel with a wrought brass, bronze or stainless front. It's also windstorm and hurricane certified, which matters on coastal openings that have to hold a pressure rating.
