Corbin Russwin CLX3357-NZD-626-CT6D Grade 1 Storeroom Newport Cylindrical Leverset with Status Indicators, 2-3/4in Backset, LFIC 6-Pin, Less Core

Commercial-Grade Cylindrical Lock with Visual Status Indicators for Enhanced Security and Privacy

The Corbin Russwin CLX3300 Series Grade 1 Storeroom Newport Cylindrical Leverset delivers style, security, and enhanced privacy for both new construction and retrofit projects. Featuring six customizable indicator windows that provide instant visibility of the door's lock status on the inside, outside, or both sides of the door, this leverset is engineered for high-traffic commercial environments. Designed for doors with a 2-3/4" (70mm) backset and a standard door thickness of 1-3/4" to 2" (44mm to 51mm), it requires a minimum stile of 4-1/2" (114mm) and ships less the LFIC CR8000 core. The stainless steel latchbolt delivers a 1/2" (13mm) throw, and the unit exceeds ANSI/BHMA Grade 1 standards while carrying UL/cUL listing for 3-hour fire doors.

Professional Features & Benefits

  3. Prepare the door by drilling the required cross-bore and edge-bore holes and routing the latch pocket as specified in manufacturer instructions.
  4. Install the latchbolt assembly and strike plate, then secure the cylindrical lock body and lever trim to the door per manufacturer torque specifications.
  5. Insert the compatible LFIC CR8000 core (sold separately) into the prepared 6-pin LFIC prep and verify proper seating and key operation.
  6. Adjust the latch and strike alignment for smooth latching and verify status indicator windows are functioning correctly.

Corbin Russwin CLX3357-NZD-626-CT6D – Frequently Asked Questions

1) Does the Corbin Russwin CLX3357 storeroom lever come with a cylinder core?
No core is included. The CLX3357 ships less core, prepped for an interchangeable core that you supply from your own key system. Two prep choices exist: Large Format IC 6-pin prep with a disposable plastic core (less LFIC CR8000 core), or Small Format IC 6/7-pin prep with a disposable plastic core (less SFIC core). The plastic core lets the door be used during construction, then you swap in the permanent core. Pick the prep that matches the cores your building already runs, because an SFIC core will not seat in an LFIC prep.
2) Will the CLX3357 lever fit a 1-3/8 inch door?
No. The CLX3300 Series cylindrical lever is built for 1-3/4 inch to 2 inch doors, so a 1-3/8 inch door is out of range. For thinner doors, the Dexter C1000 Series Grade 1 classroom lever covers 1-3/8 inch to 1-3/4 inch, and the Falcon K101 Grade 1 passage lever covers 1-3/8 inch to 2-1/4 inch.
3) What does storeroom function actually do on this Corbin Russwin lever?
Outside lever is always locked and freewheels when you turn it, so no one gets in without a key. Retracting the deadlocking latchbolt from outside takes a key in the outside lever. The inside lever is always free, so anyone inside exits in one motion with no key and no thumbturn. That is the standard setup for stock rooms, mechanical rooms, and back-of-house doors that must stay secure but never trap anyone.
4) Can I use the CLX3357 on a fire-rated door?
Yes. The CLX3300 Series storeroom lever is UL/cUL listed for 3-hour fire doors, and the storeroom function suits fire openings because the inside lever always releases the latch for egress. It also exceeds ANSI/BHMA A156.2 Grade 1, which is the heavy commercial durability level.
5) Will this lever drop into my existing door prep and strike?
It needs a 2-3/4 inch backset bored prep, not the 2-3/8 inch backset common on lighter doors. The deadlatch has a square corner front measuring 2-1/4 x 1-1/8 inches with a 1/2 inch throw, and it comes with an ANSI curved lip strike with a 1-1/4 inch lip. If your frame already has ANSI strike prep and the door has a 2-3/4 inch backset chassis bore, this swaps in. Minimum stile is 4-1/2 inches.
6) What is a comparable storeroom lever if I do not need Grade 1?
Two storeroom-function lever locks sit a grade below the Corbin Russwin CLX3357. The Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever, rated for doors 1-3/8 inch to 2 inch thick, and 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. The CLX3357 is Grade 1 and is built for doors 1-3/4 inch to 2 inch, so on a thinner 1-3/8 inch door the Hager or Cal-Royal covers a range the Corbin Russwin does not.
7) The opening does not need to be keyed. What lever should I use instead of the CLX3357?
The CLX3357 is a keyed storeroom lock with a single cylinder, so it is the wrong choice for a non-keyed opening. For a Grade 1 non-keyed lever, the Falcon K101 is a Grade 1 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. The Design Hardware X75 is another Grade 1 passage lever, for 1-3/4 inch doors.
8) I need a classroom function instead of storeroom on a Grade 1 lever. What are my options?
The Corbin Russwin CLX3357 is storeroom function: the outside lever is always locked and retracts only by key, while the inside lever is always free. For a classroom opening, the Dexter C1000 is offered as a Grade 1 classroom cylindrical lever with a clutching, keyed design, and also as a Grade 1 classroom security version. Both are listed for doors 1-3/8 inch to 1-3/4 inch thick.
9) Do I have to order a left hand or right hand version of the CLX3357?
No handing to specify. The CLX3300 Series cylindrical lever is non-handed and installs on any swing, which is why it works for both new construction and retrofit without stocking two versions.
10) Can the CLX3357 be master keyed into our existing key system?
Yes. It is a single cylinder keyed lock that can be master keyed or grand master keyed, and construction key systems are available for phased jobs. The series standard cylinder is a conventional 6-pin in the L4 keyway, but ordered as shown it takes an interchangeable core, so it picks up whatever keyway your CR8000 or SFIC cores already use.
11) What else do I need to order to finish installing the CLX3357?
Plan on the permanent interchangeable core, since the lever ships with only a disposable plastic core in place. Everything else for the opening is standard with the lock: the deadlatch with the 2-1/4 x 1-1/8 inch square corner front and the ANSI curved lip strike with a 1-1/4 inch lip. Door prep is a bored cross-bore and edge-bore on a 2-3/4 inch backset with a minimum 4-1/2 inch stile.
12) Can a dummy or passage lever be used in place of the CLX3357 storeroom lock?
No. The Corbin Russwin CLX3357 is a keyed storeroom lock with a deadlocking latchbolt. Trims such as the BEST 9K 1DT single dummy, the Accentra 455LN Augusta single dummy, and the Baldwin Estate 5103 half dummy have dummy function only, with no latch at all. The Accentra 5301LN and Arrow GL01 are passage function and latch but never lock. None of them secures a storeroom.
13) I want keyless entry on a storeroom door instead of a keyed cylinder. What else works?
The Corbin Russwin CLX3357 takes an interchangeable core and is set up for master keying, so it suits a facility on key control. If you would rather not issue keys, the Lockey 2835 is a mechanical pushbutton keyless lever lock for doors 1 3/16 inch to 2 inch, the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock.
14) What is the difference between the CLX3357 and the Cal-Royal AG03 classroom lever for a 2-3/4 inch backset door?
Both are cylindrical levers cut for a 2-3/4 inch backset. The Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway supplied keyed different. The Corbin Russwin CLX3357 is Grade 1 storeroom function, supplied less core for Large Format or Small Format interchangeable core prep so it can be pinned into an existing key system.
15) Is an entrance or office function lever an acceptable substitute for the CLX3357?
Only if you want the lock to be left unlocked. Entry and office locks such as the Falcon B511CP6D Grade 2 entry/office lever and the Hager 2525 Grade 2 commercial entry lever let a user set the outside lever unlocked. The Corbin Russwin CLX3357 storeroom function keeps the outside lever locked at all times and retracts the latch only by key, which is why storeroom is specified on secured rooms.
16) What are the status indicator windows on the CLX3300 lever for?
Six customizable indicator windows show whether the door is locked or unlocked, and can be configured to read from the inside, the outside, or both. On a storeroom the outside lever is always locked, so the value is confirming status at a glance in high-traffic buildings without testing the lever. Facilities running restrooms, classrooms, and back-of-house on one platform use the same indicator system across functions.
17) Is the Newport lever ADA compliant, and what finish does it come in?
The Newport (NZD) lever design meets ADA requirements for operation without tight grasping or twisting, which is what pushes most commercial jobs off knobs. It is offered in 626 satin chrome, the standard commercial finish for matching across a building.
18) Will this lock hold up in a corrosive or wash-down area?
The lock body uses steel with a zinc dichromate coating for corrosion resistance, and the deadlatch bolt is stainless steel. That plus Grade 1 durability suits warehouses, mechanical spaces, and institutional back-of-house. It is not a marine or exterior-exposure rating, so for constant salt or moisture exposure treat it as a protected-opening lock.
