Corbin Russwin CL3391-KEYED Extra Heavy-Duty Cylindrical Lever Lock with Keyed Lever & Turnpiece Function

Grade 1 Commercial Cylindrical Lockset for High-Traffic Institutional and Commercial Applications

The Corbin Russwin CL3391 is an extra heavy-duty, Grade 1 cylindrical lever lock from the CL3300 Series, engineered for demanding commercial, industrial, and institutional environments. This keyed lever and turnpiece function lock features a deadlocking latchbolt operated by lever or turnpiece, except when the lever is locked by key — at which point the latchbolt is operated by key in the lever or by the turnpiece, with the lever handle freewheeling in the locked position. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CL3391 is built from steel with zinc dichromated corrosion-resistant construction and includes a conventional 6-pin cylinder with two nickel silver keys. The most common configuration features the NZD Newport lever in a 626 Satin Chrome finish.

Corbin Russwin CL3391 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CL3391 lever lock fit a 1-3/4 inch commercial door with a 2-3/4 inch backset prep?
That is exactly the standard prep for the CL3391. It ships for 1-3/4 inch to 2 inch doors with a 2-3/4 inch backset, and the standard deadlatch is a square corner front measuring 2-1/4 x 1-1/8 inches. If your existing openings are bored on the wider 3-3/4 inch or 5 inch backset, those are available as options instead of the standard. Doors thicker than 2 inch, up to 2-1/4 inch, are also an option.
2) Do I need to specify handing when I order a CL3391 lever lock?
No handing to specify. The CL3391 is non-handed, so the same lock works on a left or right hand opening and one part number covers both swings across a building. The only exception in the CL3300 Series is FZD trim.
3) Can I put a Corbin Russwin CL3391 on a fire rated door?
Yes, the CL3391 carries a fire rating and the CL3300 Series is UL-cUL listed. For a fire door you generally want the optional 3/4 inch throw fire latch rather than the standard 1/2 inch stainless steel latchbolt, since the longer throw is what fire door assemblies typically call for. The series also lists ANSI A117.1 accessibility and California State Fire Marshal.
4) Can I get the CL3391 keyed into my existing master key system or interchangeable core system?
Yes, and the cylinder choice is made at order time. Standard is a conventional 6-pin brass cylinder in the L4 keyway, 0-bitted. If you run cores, order it less core for Corbin Russwin LFIC in 6-pin (CL6) or 7-pin (CL7), less core SFIC prep (M08) which accepts 6 or 7-pin in all designs, or less core FSIC for Schlage (M69). LC gets you the lock with no conventional cylinder at all so your locksmith supplies it. Keying is specified as keyed different or keyed alike when several locks need to run on one key.
5) My doors are 1-3/8 inch. Can I still use the Corbin Russwin CL3391?
No. The CL3391 starts at 1-3/4 inch and runs to 2 inch, so a 1-3/8 inch door, common on older interior openings, is below its range. For that thickness look at the Falcon K101, rated 1-3/8 inch to 2-1/4 inch, or on the Grade 2 side the Hager 2525 entry lever at 1-3/8 inch to 2 inch. Cal-Royal's AG05 storeroom lever also covers 1-3/8 inch to 1-3/4 inch.
6) What is the equivalent for a classroom door if the CL3391 keyed lever and turnpiece function is not right?
On a classroom door the teacher usually needs to lock the outside lever by key without a turnpiece on the inside face. The Corbin Russwin CL3391 uses a keyed lever and turnpiece function, so the latchbolt can also be released by the turnpiece. Classroom-function alternatives include the Dexter C1000 Series Grade 1 classroom cylindrical lever lock and the Dexter C1000 Series Grade 1 classroom security lever lock, both clutching and keyed, and the Cal-Royal AG03 classroom lever with a 6-pin Schlage C keyway and a 2-3/4 inch backset, matching the CL3391 2-3/4 inch backset.
7) What is the closest Grade 1 cylindrical lever lock to the Corbin Russwin CL3391 if I need a keyed function from a different manufacturer?
The Corbin Russwin CL3391 is a Grade 1 cylindrical lever lock with a keyed lever and turnpiece function, where the deadlocking latchbolt is operated by lever or turnpiece except when the lever is locked by key. The nearest keyed Grade 1 cylindrical lever lock from another brand is the Dexter C1000 Series Entry/Office lock, which is Grade 1, keyed, with a clutching lever and an entry/office function. The functions differ: the CL3391 locks and unlocks the outside lever from an inside turnpiece plus key, while the Dexter C1000 entry/office lock is an entrance function. Both are cylindrical lever locks, so both use a standard bored door prep.
8) I need a storeroom function instead of a keyed lever and turnpiece - what lever lock should I use?
A storeroom function keeps the outside lever locked at all times and is entered by key only, with no inside turnpiece to unlock it. The Corbin Russwin CL3391 is instead a keyed lever and turnpiece function, so the latchbolt can be released by the turnpiece as well as by key. For a storeroom opening, the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt, and the Hager 2580 with the Withnell lever is a Grade 2 storeroom cylindrical lock for doors 1-3/8 inch to 2 inch thick. Both are Grade 2 where the CL3391 is Grade 1.
9) What lock matches the CL3391 for a psychiatric or utility room where both sides must be keyed?
That is an asylum or institution function, where both the inside and outside levers are locked and released by key with no free egress. The Corbin Russwin CL3391 is a single cylinder lock with the inside controlled by a turnpiece, so it does not serve that opening. The Dexter C1000 Series asylum lock is a Grade 1 cylindrical lock with an asylum function for doors 1-3/8 inch to 2 inch thick, matching the CL3391 Grade 1 rating, and the Arrow MK33-BD-CS is a heavy duty asylum lock with a ball knob and a conventional Schlage C keyway cylinder rather than a lever.
10) Can I use a passage lever like the Falcon T101 or K101 in place of the CL3391?
No - those are non-keyed. The Corbin Russwin CL3391 is keyed, single cylinder, with a deadlocking latchbolt controlled by key or turnpiece. The Falcon T101 is a Grade 1 heavy duty cylindrical passage lever lock and the Falcon K101 is a Grade 1 heavy duty passage lock with non-handed levers for doors 1-3/8 inch to 2-1/4 inch thick. Both match the CL3391 Grade 1 rating and heavy duty level, but a passage function has no lock at all - the lever always retracts the latch. Use a passage lever only on an opening that never needs to secure.
11) My doors are 1-3/8 inch thick - which lever locks fit if the CL3391 does not?
The Corbin Russwin CL3391 covers 1-3/4 inch to 2 inch doors as standard. For a thinner 1-3/8 inch door, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 Series asylum lock covers 1-3/8 inch to 2 inch, and the Hager 2510 Grade 2 passage lever with the Withnell design covers 1-3/8 inch to 2 inch. The Cal-Royal AG05 Grade 2 storeroom leverset covers 1-3/8 inch to 1-3/4 inch. Match the function you need as well as the thickness - those four are passage, asylum, passage, and storeroom respectively, not the CL3391 keyed lever and turnpiece function.
12) Our building is keyed to Schlage - does that rule out the Corbin Russwin CL3391?
It does not. The CL3391 ships standard with a conventional 6-pin L4 keyway cylinder, but it is also offered with an M69 less core FSIC prep for Schlage cores, an M08 less core SFIC prep that accepts 6 or 7-pin cores in all designs, and an LC less conventional cylinder option so the cylinder can be supplied from the existing system. Among the comparables, the Cal-Royal AG03 classroom lever and the Cal-Royal AG00 entrance lever come with a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS carries a conventional Schlage C keyway cylinder.
13) Is a Grade 1 cylindrical lever like the CL3391 overkill for an office door, or should I step down to a Grade 2?
Grade 1 is the extra heavy duty tier under ANSI/BHMA A156.2 Series 4000, and it is what you want on doors that get cycled hard: schools, healthcare corridors, warehouses, multi-tenant common doors. On a low-traffic interior office or closet a Grade 2 lever is the usual spec, and Hager's 2525 entry lever or the Falcon B511CP6D entry/office lever are Grade 2 cylindrical options. Standardizing a whole facility on one Grade 1 chassis is often the cheaper move over time than mixing grades, since the trim, latch and strike stay common.
14) What lever designs and finishes can I get the Corbin Russwin CL3391 in to match the rest of my building?
Three lever designs are orderable: Armstrong (AZD), Newport (NZD) and Princeton (PZD), all solid cast. Fourteen finishes run from 605 bright brass and 606 satin brass through 611 and 612 bronze, 613 satin bronze oil-rubbed with 613E and 613L variants, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze oil-rubbed, plus BSP black suede and WSP white suede powder coat. Most commercial jobs land on the NZD Newport lever in 626 satin chrome, which is the common configuration.
15) I need a lever lock that can be released from a card reader or access control panel. Does the CL3391 do that?
The CL3391 itself is a mechanical lock. For access control, the CL33900 electrified option in the same series is what you order: fail safe or fail secure, 12 or 24VAC/VDC, drawing 250mA at 12V and 150mA at 24V on a continuous duty solenoid, with an ElectroLynx 8-pin connector on every electrified product. Fail safe unlocks when power drops, fail secure stays locked, so egress and life safety on that opening decides which one you spec.
16) Will this lever lock hold up in a healthcare or school corridor where levers get abused?
That is the environment the CL3300 Series chassis is built for. The chassis is steel, zinc dichromated for corrosion resistance, with anti-rotational through-bolts at the 6 and 12 o'clock positions so the trim cannot be spun off the door, and independent return springs so the levers do not sag after heavy use. When the lever is locked it freewheels rather than transmitting force into the chassis. There is also a MicroShield antimicrobial coating option (suffix C) that facilities frequently add on patient-side and food-service doors.
17) Is the CL3391 the right function for a classroom, or do I need a classroom security lock?
For a classroom where staff need to lock the door from inside without stepping into the corridor, the CL3391 is not the function you want. Its turnpiece retracts the latch but the outside is keyed for entry, so it reads as a storeroom-style secured opening rather than an intruder function. The CL3352 Classroom Intruder function in the same series is the one built for that: double cylinder with always-free egress. Across brands, the Dexter C1000 Series classroom security lever is another Grade 1 option for that condition.
18) If I am standardizing a building on Grade 1 lever hardware, which non-keyed levers pair with the CL3391 on the interior doors?
Keep the same grade across the openings so the whole set carries the rating. The Corbin Russwin CL3391 is Grade 1 heavy duty and handles the keyed doors. For interior doors that only need to latch, the Falcon K101 is a Grade 1 heavy duty passage lock with non-handed levers, the Falcon T101 is a Grade 1 heavy duty passage lever, and the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. On inactive leaves, the BEST 9K Series 1DT is Grade 1 heavy duty dummy trim. The CL3391 itself is non-handed, as is the Falcon K101.
19) Is a Grade 2 entry lever a workable substitute for the Corbin Russwin CL3391 on a lower-traffic office door?
It can be, provided the opening does not need Grade 1 performance. The Corbin Russwin CL3391 is Grade 1, heavy duty, and fire rated. Grade 2 keyed lever options include the Falcon B511CP6D, a medium duty Grade 2 cylindrical lever lock with an entry/office function, and the Hager 2525, a Grade 2 commercial cylindrical entry lock for doors 1-3/8 inch to 2 inch thick. Both are entry/office functions rather than the CL3391 keyed lever and turnpiece function, so the inside turnpiece control is not carried over.
20) A dummy lever is listed at the same grade as the CL3391 - are they interchangeable?
They are not. The Corbin Russwin CL3391 is a keyed cylindrical lever lock with a deadlocking latchbolt and a 2-3/4 inch backset. The BEST 9K Series 1DT single dummy trim is Grade 1 and heavy duty like the CL3391, and the Accentra 455LN Augusta is a Grade 1 dummy from the 5400 Series, but a dummy trim is a fixed pull with no latch and no chassis - it does not bore into the door the way a cylindrical lock does and it cannot latch or lock. Dummy trim is for an inactive leaf or a closet face where the door is held by a catch.
21) What should I use instead of the CL3391 if I do not want to issue keys to tenants or staff?
A mechanical keypad lever removes keys from the opening entirely. The Corbin Russwin CL3391 is keyed with a conventional 6-pin L4 keyway cylinder. Keyless alternatives include the Lockey 1150 heavy duty mechanical keypad lever set with double combination for doors 1-1/8 inch to 2 inch thick, and the Lockey 2835 mechanical pushbutton keyless lever lock with an ADA compliant lever for doors 1-3/16 inch to 2 inch thick. Both are passage function, so they release the latch on a code rather than deadlocking the way the CL3391 does. The Delaney LP250 is an electronic keypad leverlock at Grade 2.
22) Is a residential-style entry leverset like the Kwikset or Baldwin an option for a commercial opening that calls for the CL3391?
The Corbin Russwin CL3391 is a commercial Grade 1, heavy duty, fire rated cylindrical lever lock. The Kwikset 200BRNL Breton passage lever and the Kwikset 300BRNL Breton privacy lever are Grade 3 for doors 1-3/8 inch to 1-3/4 inch thick, and the Master Lock RL Series keyed entry lever is Grade 3 entrance function. The Baldwin Estate 5103 is offered in passage, privacy, and half dummy versions with the 5048 rose. These are lighter-grade or non-keyed trims aimed at residential and light interior use, and none carries the CL3391 Grade 1 rating or its keyed lever and turnpiece function.
23) I need a privacy function for a restroom, not a keyed lock - what replaces the CL3391 there?
A restroom needs privacy, which locks from the inside with a thumbturn and releases with an emergency tool from outside, not a cylinder. The Corbin Russwin CL3391 is keyed with a 6-pin cylinder, so it is the wrong function. The Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed, fire rated, for doors 1-3/4 inch to 2 inch thick - the same thickness range the CL3391 covers. In lever trim, the Hager 2540 with the Withnell lever and the Baldwin Estate 5103 privacy lever are the privacy options.
24) Can I replace a knob lock with the CL3391 lever, and what if I want to stay with knobs?
The Corbin Russwin CL3391 is a lever handle cylindrical lock on a 2-3/4 inch backset for 1-3/4 inch to 2 inch doors, and lever trim is what an ADA-governed opening generally calls for. If the opening is staying on knobs, the comparable knob-trim cylindrical locks are the Arrow HK11 turn-pushbutton entrance lock with a ball knob and conventional cylinder for 1-3/8 inch to 1-3/4 inch doors, the Arrow MK02-TA privacy lock with a Tudor knob for 1-3/4 inch to 2 inch doors, and the Arrow MK33-BD-CS asylum lock with a ball knob. Confirm the backset and door thickness before swapping trim styles, since those knob locks list different thickness ranges.
25) Can one person install a CL3391 lever lock without special tools if the door is already bored?
On an ANSI/DHI A115.18 prepped door with a 2-3/4 inch backset, it goes in with the EZ-Install components the series uses, which cut installation time, and it is non-handed so there is nothing to reverse on the bench. The through-bolts land at 6 and 12 o'clock. The one thing to confirm before you start is the latch front shape, square or rounded corner, against what is already mortised into the door edge.
26) What is the difference between the CL3391 and a Grade 2 lever from the same kind of commercial line?
Grade is the ANSI/BHMA durability tier, and the Corbin Russwin CL3391 sits at Grade 1, heavy duty, fire rated, with a steel chassis that is zinc dichromated for corrosion resistance. Grade 2 commercial levers in the same cylindrical format include the Accentra 5301LN Augusta passage lever from the 5300 Series, the Accentra 4601LN passage lever with Augusta trim from the 4600 Series, the Arrow GL01 Sierra lever passage lock for 1-3/4 inch to 2 inch doors, and the Falcon B101 medium duty passage lever from the B Series. Those are all passage function and non-keyed, where the CL3391 is keyed single cylinder.
