Corbin Russwin CLX3381-KEYED Cylindrical Lever Lock - Keyed Lever & Blank Plate, ANSI F113, Grade 1

ANSI/BHMA Grade 1 Cylindrical Lock with Freewheeling Lever Release and 20 Million Cycle Verification

The Corbin Russwin CLX3381-KEYED is a commercial-grade cylindrical lever lock from the CLX3300 Series, engineered to ANSI/BHMA Grade 1 standards for high-traffic interior and exterior door applications. Configured to ANSI function F113, this lock features a keyed lever on one side and a blank plate on the other, with a deadlocking latchbolt that is controlled by the lever except when locked by key — at which point the lever handle freewheels for vandal resistance. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CLX3381-KEYED is manufactured from steel with zinc dichromate treatment for corrosion resistance, and supports a conventional 6-pin cylinder with L4 keyway. The most common configuration features the NZD Newport lever in 626 Satin Chrome finish.

Corbin Russwin CLX3381 NZD 626 – Frequently Asked Questions

1) What does the Corbin Russwin CLX3381 actually do on the door - what is the F113 function?
The CLX3381 is ANSI function F113: a keyed lever on one side and a blank plate on the other, so there is no operating trim on the blank-plate face at all. The deadlocking latchbolt retracts by the lever except when locked by key. Once locked, the lever freewheels instead of resisting force, which is what protects the chassis from someone hanging on the handle. Use it where entry is controlled from one side only and the other side is not meant to be an opening point, for example a service or equipment room off a corridor.
2) Will the CLX3381 lever lock fit a 1-3/8 inch door or a door over 2 inches?
Standard build covers 1-3/4 inch to 2 inch doors, which is the normal commercial range. For a 1-3/8 inch door you have to order the D138 option, and for doors over 2 inches up to 2-1/4 inches you order D214. The chassis uses an adjustable push/turn button so thickness is set during install rather than by picking a different chassis.
3) Does the Corbin Russwin CLX3381 come in a 2-3/8 inch backset for a residential-prep door?
Standard backset is 2-3/4 inches, the usual commercial prep. Corbin Russwin also offers 2-3/8 inch, 3-3/4 inch and 5 inch backsets on the CLX3300 Series, so a 2-3/8 inch prep is covered, but it has to be specified on the order. The 3-3/4 and 5 inch options exist for wide-stile and unusual door conditions.
4) Can I use this Corbin Russwin cylindrical lever lock on an aluminum door with a narrow stile?
Only if the stile is at least 4-1/2 inches. The CLX3300 Series cylindrical chassis needs that minimum stile width, so a typical narrow-stile storefront door will not take it. Standard hollow metal and wood doors are the intended application, and the door prep follows ANSI/SDI A250.14.
5) Is the CLX3381 fire rated, and does the standard latch work on a fire door?
Yes, fire rated, with UL/cUL 3-hour listing and NFPA 80 compliance stated for the CLX3300 Series. The standard latchbolt is stainless steel with a 1/2 inch throw; a 3/4 inch deadlocking fire latch is available as an option, which is what you specify when the opening or the frame gap calls for the longer throw. It is also stated as ADA A117.1 compliant, which the lever trim satisfies.
6) Will the CLX3381 latch into the strike already in my frame?
The lock ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center, and the latch front is 2-1/4 x 1-1/8 inches with a square corner. If your frame already carries a standard ANSI 4-7/8 inch strike prep, the supplied strike drops straight in. With only a 1/2 inch latch throw, a frame that sits back from the door will not hold reliably, which is when the 3/4 inch latch option is worth specifying.
7) I key my building on small format interchangeable core - can I order this lock less core?
Yes. Cylinder choices on the CLX3381 include M08 less core SFIC prep, which accepts 6 or 7-pin cores in all designs, plus CL6 and CL7 less-core Corbin Russwin large format IC, M69 less core Schlage FSIC, and LC less conventional cylinder. The default is a conventional 6-pin cylinder in the L4 keyway, shipped 0-bitted. Pick the less-core option that matches the cores you already stock so the lock can join your existing keying system.
8) Is the CLX3381 a substitute for a storeroom lock, and what if I need egress trim on the inside?
Not the same thing. A storeroom function has a lever on both sides, with the inside lever always free for egress. The CLX3381 has a blank plate on the inside face, so there is no way to operate it from that side at all, which rules it out on any door someone can be behind. For a keyed outside lever with free inside egress, use a storeroom function such as the Cal-Royal AG05 or Hager 2580 in Grade 2, or a Grade 1 storeroom in the same CLX3300 Series.
9) What is the closest Grade 1 keyed cylindrical lever lock to the Corbin Russwin CLX3381 if the opening is a classroom rather than a storeroom-style door?
The CLX3381 is an ANSI F113 keyed lever with a blank plate on the opposite side, so it is a single-cylinder lock with no trim to operate from the far face. For a classroom opening where the inside lever must always retract the latch, the Dexter C1000 Series classroom lock is a Grade 1 cylindrical lever lock in classroom function with a clutching lever, listed for 1-3/8 inch to 1-3/4 inch doors. If the opening needs locking from either side of the door, Dexter also builds the C1000 in Classroom Security function at Grade 1. Both keep you at Grade 1, which is what the CLX3381 carries.
10) I need a lever lock on the same commercial door but the room does not need to be keyed - what do I use instead of the CLX3381?
The CLX3381 is a keyed lock, so for an unkeyed opening you want a passage function instead. Staying at the same ANSI grade, the Falcon K101 is a Grade 1 heavy duty cylindrical passage lock with non-handed levers, fire rated, and covers 1-3/8 inch to 2-1/4 inch doors - a wider thickness range than the CLX3381 standard 1-3/4 inch to 2 inch. The Falcon T101 is another Grade 1 heavy duty cylindrical passage lever, and the Dexter C1000 passage is Grade 1 with a clutching lever. If the door is lower traffic, the Hager 2510 and Falcon B101 are Grade 2 passage levers.
11) If my building is keyed to Schlage, do I have to move off the Corbin Russwin CLX3381?
No. The CLX3381 ships standard with a conventional 6-pin L4 keyway cylinder, but it can be ordered as M69 less core for a Schlage FSIC or M08 less core with SFIC prep that accepts 6 or 7-pin cores in all designs, so your existing cores go straight in. Among comparable locks, the Cal-Royal AG00 entrance and AG03 classroom levers come with a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS uses a conventional Schlage C cylinder, but those are Grade 2 or Grade 3 class sets rather than Grade 1.
12) Do I need to specify handing when ordering the CLX3381 keyed lever lock?
No handing to call out. The CLX3300 Series cylindrical chassis is non-handed, so one part number covers left and right hand openings and the lever is field-reversible at install. What you do have to specify is keying (keyed different or keyed alike), lever design (Armstrong, Newport or Princeton) and finish.
13) Can I get a set of these keyed alike across several doors?
Yes. Keying is a required choice at order: KD keyed different, or KA keyed alike for a group of doors that should open on one key. There is also a free-text field for special cylinder or keying requirements, which is where you note a master key system, a specific keyway, or bitting to match an existing building system. The stock cylinder is a conventional 6-pin L4 keyway.
14) Is a Grade 1 lock like this overkill, or should I use a Grade 2 lever on interior doors?
Grade 1 earns its place on high-traffic and abused openings: the CLX3381 is tested to ANSI/BHMA A156.2 (2022) Series 4000 Grade 1 and carries a UL cycle verification at 20 million cycles, with over 3,100 in-lb locked lever torque and over 1,600 lbs offset lever pull. On low-traffic interior doors that never see that load, a Grade 2 cylindrical lever such as the Hager 2580 storeroom or the Falcon B511CP6D entry/office function does the job. Where the door is keyed, public-facing and gets pulled on, stay Grade 1.
15) I need a Grade 1 lever lock but on a 1-3/8 inch door without ordering a special option - what else could I use?
The Falcon K101 covers 1-3/8 inch to 2-1/4 inch doors as standard and is a Grade 1, heavy duty, fire rated cylindrical lever, but it is passage function, so it does not lock. For a Grade 1 keyed lever on thinner doors, the Dexter C1000 Series classroom and classroom security models are listed for 1-3/8 inch to 1-3/4 inch doors. The CLX3381 itself reaches 1-3/8 inches only with the D138 option, so if you would rather not add an option code, those are the alternatives.
16) Can I standardize a whole facility on the CLX3300 Series and still get classroom and electrified openings?
Yes, that is the usual reason to spec the series. The CLX3300 Series runs 27 mechanical and 2 electrified functions off the same chassis and door prep, including the CLX3352 classroom intruder function that locks from either side with always-free egress. Electrified units use the ElectroLynx 8-pin molex connector and run 12VDC or 24VDC, 10mA continuous with a 500mA peak, and carry UL294. Behavioral health (BHSS) trim and VSL visual status indicators are available where the occupancy calls for them, so one prep and one keyway can cover mixed door types across the building.
17) What pairs with a CLX3381 on the inactive leaf of a pair of doors or a closet that only needs a pull?
The CLX3381 is a working keyed lock, not trim, so for a leaf that only needs a lever to pull on you want a dummy. The BEST 9K Series 1DT single dummy trim is a Grade 1 non-keyed cylindrical lever, which keeps the dummy at the same grade level as the CLX3381. The BEST 7KC Series 1DT is the medium duty Grade 2 equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever. Levers will not match the Corbin Russwin Armstrong, Newport, or Princeton designs across brands, so confirm appearance if the two leaves are seen together.
18) Which alternatives to the CLX3381 suit a privacy door such as a restroom or bedroom?
A privacy set is the right function there, not the keyed CLX3381, which is single cylinder with a blank plate on the reverse. The Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a Grade 2 privacy set with a Tudor knob and is fire rated, and the Baldwin Estate 5103 privacy lever with the 5048 rose covers decorative openings. Privacy sets lock by inside button with an emergency release, so they do not take a keyway or a core the way the CLX3381 does.
19) How does the Design Hardware X75 compare with the Corbin Russwin CLX3381?
The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever, listed for 1-3/4 inch doors, and the J75 is the Grade 2 passage version of the same flat lever. Both are non-keyed, so neither replaces the keyed CLX3381 on a door that has to lock. The CLX3381 is Grade 1, non-handed, keyed to a 6-pin L4 cylinder, and fire rated, for 1-3/4 inch to 2 inch doors. Use the X75 on the corridor or closet leaves of the same project where you want a Grade 1 lever without a cylinder.
20) What finishes does the Corbin Russwin CLX3381 come in for matching existing building hardware?
Fourteen finishes: 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 with the NZD Newport lever is the common commercial configuration, so that is usually the match on an existing institutional job.
21) Will this lock hold up outdoors or in a damp mechanical room?
The chassis is steel with a zinc dichromate treatment for corrosion resistance, and Corbin Russwin lists the CLX3300 Series for both interior and exterior commercial openings, including windstorm and hurricane certified applications. Latch is stainless steel. For coastal exposure, pick the finish accordingly rather than relying on the chassis treatment alone.
