Corbin Russwin CL3810 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CL3810 passage lever fit a 1-3/8 inch interior door?
Yes. The CL3810 cylindrical passage lever is built for doors 1-3/8 inch through 1-3/4 inch, so it covers both older 1-3/8 inch interior doors and the 1-3/4 inch commercial standard. It works on a 2-3/4 inch backset, which is the usual commercial bore layout. If your doors are thicker than 1-3/4 inch, this is not the right chassis for them.
2) Does the CL3810 lever lock ever need to be keyed, or does it always stay unlocked?
It never locks. The CL3810 is a non-keyed passage function (ANSI F75): latchbolt retracts by lever from either side and both levers are always free. There is no cylinder, no pushbutton, no thumbturn. Use it on corridor, hall and closet doors where you only want a latch to hold the door closed. If the room needs to be secured or privacy-locked, this is the wrong function.
3) Do I have to specify handing when ordering a Corbin Russwin CL3810?
No handing to specify. The CL3810 is non-handed, so one part number covers left and right hand openings and you can stock a single SKU across a building instead of splitting the order. The spring cassette is non-handed as well, which is what keeps the levers from sagging over time.
4) Will a CL3810 fit on an aluminum storefront or narrow stile door?
No. The CL3810 needs a minimum stile of 4-1/2 inches, which rules out typical narrow stile aluminum entrance doors. It's a bored cylindrical lock for wood and hollow metal openings. For a glass front narrow stile opening you want narrow stile rated hardware rather than a bored lever chassis.
5) The CL3810 will not work on my door because it is thicker than 1-3/4 inch. What passage lever fits?
The CL3810 covers 1-3/8 inch to 1-3/4 inch doors. For thicker stock, the Arrow GL01 is a Grade 2 non-keyed passage cylindrical lock with a Sierra lever for 1-3/4 inch to 2 inch doors, the Hager 2510 is a Grade 2 passage cylindrical lever for 1-3/8 inch to 2 inch doors, and the Falcon K101 is a Grade 1 passage cylindrical lock reaching 2-1/4 inch. Confirm the door thickness at the lock edge before ordering, since all three are cylindrical bored preps like the CL3810.
6) What is the closest equivalent to a Corbin Russwin CL3810 passage lever from another brand?
The CL3810 is a Grade 2 non-keyed passage/closet cylindrical lever lock, latchbolt by lever from either side with both levers always free. The Falcon B101 is a Grade 2 medium-duty passage/hall/closet cylindrical lever lock with a non-handed design, matching the CL3810 on grade, function and medium duty level. The Accentra 5301LN Augusta is also a Grade 2 passage/hall/closet cylindrical lever in the 5300 Series, and the Hager 2510 with Withnell lever is a Grade 2 passage cylindrical lever covering 1-3/8 inch to 2 inch doors. Any of the three lands a passage opening at the same grade and function as the CL3810.
7) What passage lever should I use instead of the CL3810 on a heavy-traffic opening?
The CL3810 is a Grade 2 medium-duty passage lever. Where the opening calls for Grade 1, the Falcon K101 is a Grade 1 heavy-duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors, and the Falcon T101 is a Grade 1 heavy-duty passage cylindrical lever with Pressure Release Technology in the T Series. The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. All three keep the passage function while moving to Grade 1.
8) Can I use a dummy lever in place of a CL3810 passage lock?
No. The CL3810 has a working latchbolt operated by the lever from either side, so it holds the door closed. A dummy trim has no latch and no moving chassis; it is surface trim for a door held by other means. The BEST 7KC Series 1DT is a Grade 2 medium-duty single dummy trim cylindrical lever, and the BEST 9K Series 1DT is the Grade 1 heavy-duty single dummy trim. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever in the 5400 Series, and the Callan Bentley is a Grade 2 dummy lever. Use those only on inactive leaves or closet doors with a magnetic or roller catch, not where a latch is required.
9) I need to lock the door, not just latch it. What replaces the CL3810 for a keyed or privacy opening?
The CL3810 is non-keyed with both levers always free, so it never secures the opening. For a keyed office or entry opening, the Falcon B511CP6D is a Grade 2 medium-duty cylindrical lever with entry/office function and the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle for 1-3/8 inch to 2 inch doors. For a storeroom, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt. For a restroom or bedroom, the Baldwin Estate 5103 privacy lever with 5048 rose gives a privacy function. All of these change the function; only the passage models keep the CL3810 free-both-sides behavior.
10) Can a CL3810 lever lock be installed in an existing 2-1/8 inch knob bore?
The CL3810 chassis works on a 2-3/4 inch backset with a 1/2 inch throw latchbolt that suits either a 7/8 inch or a 1 inch edge bore. That means a standard ANSI A156.115 cylindrical prep takes it without redrilling the face bore, which is the common case when you're swapping old knobs for levers to get lever operation on the door. Confirm the edge bore is 7/8 or 1 inch before you pull the old chassis.
11) Is a Grade 2 passage lever heavy enough for a school or hospital corridor, or should I step up to Grade 1?
The CL3810 is a medium duty Grade 2 lockset per ANSI/BHMA A156.2 Series 4000. That's appropriate for office corridors, closets, and multi-family interiors. For a high-traffic institutional corridor where you want Grade 1, look at a heavy duty passage lever like the Falcon K101 or the Falcon T101, both Grade 1 passage function. The trade off is cost against cycle life; a passage latch on a closet door rarely justifies Grade 1.
12) What's the difference between the Corbin Russwin CL3810 and a Grade 2 passage lever like the Accentra 5301LN or Hager 2510?
All three are Grade 2 cylindrical passage levers. The CL3810 works doors 1-3/8 to 1-3/4 inch on a 2-3/4 inch backset, non-handed, with a UL 3-hour fire rating. The Accentra 5301LN Augusta is a Grade 2 passage lever in the 5300 Series, and the Accentra 4601LN is the same function in the 4600 Series with Augusta trim. The Hager 2510 with Withnell lever is Grade 2 passage and covers a wider 1-3/8 to 2 inch door range, which matters if some of your doors run thicker than 1-3/4 inch. Choose on lever style, door thickness, and what the rest of the building is already standardized on.
13) Which lever style and finish do I pick to match the rest of the doors in my building?
Three lever designs are offered on the CL3810: Armstrong (AZD), Newport (NZD) and Princeton (PZD). Finishes run to fourteen: bright brass 605, satin brass 606, bright bronze 611, satin bronze 612, oil-rubbed satin bronze 613, 613E dark oxidized satin bronze equivalent, 613L, bright nickel 618, satin nickel 619, bright chrome 625, satin chrome 626, 722 black oxidized bronze oil-rubbed, BSP black suede and WSP white suede powder coat. For most commercial corridors the match is 626 satin chrome or 630-family satin stainless look; check the number stamped inside your existing rose before ordering.
14) Does the CL3810 lever break if someone hangs on it or pries it?
The levers are solid cast with no plastic inserts and use Corbin Russwin's Lever Release freewheeling design, so force applied to the lever lets it spin free rather than transmitting into the chassis. Thrubolts hold the chassis from rotating in the door, which is the other common failure on abused passage doors. The substrate is steel with a zinc dichromate coating for corrosion resistance.
15) I need a lever on a closet door for looks only, with no latch. Is the CL3810 what I want?
No. The CL3810 has a working latchbolt that keeps the door closed. If you want trim with no latch at all, that's a dummy lever: the BEST 7KC Series 1DT single dummy trim is Grade 2 medium duty, and the BEST 9K Series 1DT is the Grade 1 heavy duty version. Use the CL3810 where the door needs to actually latch shut.
16) Can I standardize a whole building on the CL3800 Series and mix passage with keyed openings?
Yes, that's the point of the series. The CL3810 is the non-keyed passage member of the CL3800 Series, and Corbin Russwin builds it alongside the Grade 1 CL3300 and CL3500 locksets, so you can run the same lever designs and finishes across corridor passage doors and keyed openings while spending Grade 1 money only where the traffic warrants it. Same 2-3/4 inch backset and non-handed chassis keeps the door preps and the spare parts bin consistent.
17) Is there a lighter-duty passage lever than the Corbin Russwin CL3810 for interior residential doors?
The CL3810 is a commercial Grade 2 passage lever. For interior hall and closet doors that do not need commercial grade, the Callan Asheville is a Grade 3 passage leverset in a satin nickel finish, and the Kwikset 200BRNL Breton is a Grade 3 passage lever set for 1-3/8 inch to 1-3/4 inch doors, the same door thickness range the CL3810 covers. The Kwikset 200DL Delta passage lever ships with an adjustable 6AL latch and RCS strike.
18) How do knob locks compare to the CL3810 lever for ADA openings?
The CL3810 uses a lever handle, which is what ADA-compliant openings call for. Several cylindrical peers in the same bored family use knobs instead: the Arrow HK11 is a Grade 2 turn-pushbutton entrance cylindrical lock with a ball knob, the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob and a fire rating for 1-3/4 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy-duty asylum cylindrical lock with a ball knob. Those install into the same style of bored prep but do not give you a lever operator.
19) Is a keypad lever an alternative to the CL3810 for a closet or storage room?
The CL3810 is a non-keyed passage lever, free from both sides at all times, so it controls nothing. If the storage room actually needs restricted access without keys, the Lockey 1150 is a heavy-duty mechanical keypad lever set with double combination and passage function for 1-1/8 inch to 2 inch doors, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. These add code entry that the CL3810 does not have.
20) What is the difference between the Accentra 5301LN and 4601LN as substitutes for a CL3810?
Both are Grade 2 passage/hall/closet cylindrical lever locks, the same grade and function as the CL3810. They differ by series: the 5301LN Augusta is in the 5300 Series and the 4601LN uses Augusta trim in the 4600 Series. Pick by which series the rest of the building is already standardized on, since both meet the CL3810 at Grade 2 passage.
21) Are Design Hardware J75 and X75 interchangeable with a CL3810 passage lever?
Both are passage/hall/closet lever locksets with a flat lever listed for 1-3/4 inch doors, which falls inside the CL3810 range of 1-3/8 inch to 1-3/4 inch. The J75 is Grade 2 in the J Series, matching the CL3810 grade; the X75 is Grade 1 in the X Series. If the spec calls for Grade 2 passage, the J75 sits at the same grade as the CL3810.
22) What passage lever matches a decorative interior scheme instead of the CL3810 commercial trim?
The CL3810 is a commercial Grade 2 lever offered with Armstrong, Newport and Princeton lever designs. For a decorative interior where the trim style drives the choice, the Baldwin Estate 5103 passage lever with 5048 rose is a residential-style passage lever, and Bravura offers Grade 2 passage leversets in several trim designs: the Miramar with round trim in US4 satin brass, the Atlanta with round trim, the Orlando with round trim, and the Tampa with square trim. All keep passage function while changing the look at the door.
