Kwikset 408CNL-514-RCAL-UL-3031 – Frequently Asked Questions

1) Is the Kwikset 408CNL Carson lever a locking lever or just a passage lever?
The 408CNL Carson is a privacy lever, so it locks. It uses a pushbutton in the inside lever to lock the door for a bedroom or bathroom, and there is no key cylinder for everyday use. If you want a non-locking lever for a hallway or closet in the same Carson look, you want the passage version instead, not this one.
2) What backset does the Kwikset Carson privacy lever use, 2-3/8 or 2-3/4 inch?
Either one. The RCAL latch supplied with the Carson privacy lever is adjustable between a 2-3/8 inch and a 2-3/4 inch backset, which covers both of the standard bore positions used on residential and light commercial doors. You set it at install, so you do not have to measure the existing prep before ordering.
3) Do I need to order a left hand or right hand Carson lever?
Neither. The Carson lever is reversible, so the same set handles a left hand or right hand door. You flip the lever orientation during installation rather than specifying handing on the order.
4) Will the Kwikset Carson privacy lever fit a door prepped with a round corner latch face and strike?
Yes, that is exactly the prep it is built for. The set ships with the round corner adjustable latch (RCAL) and an RCS 3031 round corner full lip strike, which is the prep found on most prehung and metal-frame openings. If your existing latch face and strike are square cornered, you would have to either swap in square corner parts or file the mortise.
5) Is a Kwikset Carson privacy lever heavy duty enough for an apartment building corridor or a school?
It is a residential-duty cylindrical leverset. For apartment interiors, bedrooms and bathrooms in multi-family it is the right class of product, but for high-traffic commercial openings step up to a Grade 1 or Grade 2 commercial lock. From the commercial side, the Arrow MK02-TA is a privacy/bed/bath cylindrical lock rated for 1-3/4 to 2 inch doors, and the Hager 2540 Withnell privacy lock is a Grade 2 cylindrical unit fitting 1-3/8 to 2 inch doors.
6) I need the same Carson lever look on a closet door that should not lock. What do I use?
A privacy set like the 408CNL locks from inside, which you do not want on a closet. For a non-locking opening, passage levers include the Accentra 5301LN Augusta Grade 2, the Falcon B101 Grade 2 non-handed passage lever, the Hager 2510 Grade 2 passage lever for doors 1-3/8 inch to 2 inch, and the Callan Asheville Grade 3 passage leverset in satin nickel.
7) What is a comparable privacy lever to the Kwikset 408CNL Carson for a bed or bath door?
The Baldwin Estate 5103 Privacy Lever with 5048 Rose covers the same privacy/bed/bath function in a lever format. If you need a privacy set on a knob rather than a lever, the Arrow MK02-TA is a Tudor knob privacy/bed/bath lockset that is fire rated and fits doors 1-3/4 inch to 2 inch. The Kwikset 408CNL Carson is a privacy lever with a pushbutton, reversible for left- or right-hand doors.
8) What comes in the box with the 408CNL Carson privacy lever?
Both lever trims, the round corner adjustable latch, and the RCS 3031 round corner full lip strike, plus the mounting screws for a standard cylindrical bore. Since it is a privacy set, there is no key or cylinder in the package; the inside lever has the pushbutton.
9) Can I use this lever on a fire rated bedroom or bathroom door?
The Carson privacy lever is a fire rated set, so it can go on a rated opening. Rated assemblies still need the whole door, frame and closer package to stay within the listing, so match the lever to what the door label calls for.
10) The restroom door is high traffic and the Carson privacy lever keeps failing. What is a heavier option?
For heavier cycle duty in a lever, the Falcon K101 is a Grade 1 heavy duty cylindrical lock, fire rated, with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range, and the Falcon T101 is a Grade 1 heavy duty lever with pressure release technology. Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever, fire rated, for 1-3/4 inch to 2 inch doors. Those three are non-keyed passage function rather than privacy, so if the restroom must lock, the Accentra 107S adapter set is catalogued for apartment exit/public toilet at Grade 1.
11) Can I use a Baldwin 5103 dummy lever in place of the Kwikset 408CNL Carson privacy lever?
No. The Baldwin Estate 5103 half dummy levers are dummy function only - they are handed, sold as left hand (5103-LDM) or right hand (5103-RDM), and have no latch or locking mechanism. The Kwikset 408CNL Carson is a privacy pushbutton lever with a latch that actually retracts and a reversible lever. Dummy trim is for a fixed inactive leaf, not for a bathroom or bedroom door.
12) Is the Hager 2540 privacy lever an equivalent to the Kwikset 408CNL Carson?
The Hager 2540 is a cylindrical lock with the Withnell lever at Grade 2 for doors 1-3/8 inch to 2 inch, but its function is catalogued as entrance, which is keyed operation rather than the inside-pushbutton privacy operation of the Kwikset 408CNL Carson. For a true privacy substitute, the Baldwin Estate 5103 Privacy Lever with 5048 Rose matches the function directly.
13) We want keyless code entry on interior doors instead of a pushbutton privacy lever. What replaces the Carson 408CNL?
Mechanical keypad lever sets cover that. The Lockey 2835 single-combination keyless lever lock is ADA compliant with passage function and fits doors 1-3/16 inch to 2 inch; the 2835DC is the double-combination version of the same range. The Lockey 1150 heavy duty keypad lever set with double combination covers 1-1/8 inch to 2 inch doors. Electronic options include the Delaney LP250 Grade 2 keypad leverlock and the Emtek Classic keypad leverset.
14) The door needs to be keyed from the outside, not just a privacy pushbutton. What do I order instead of the 408CNL Carson?
Keyed lever functions in the same cylindrical format include the Cal-Royal AG00 entrance lever with a 6-pin Schlage C keyway, keyed different, 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors; the Cal-Royal AG05 Grade 2 storeroom lever with a deadlocking latchbolt; the Hager 2525 Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors; and the Falcon B511CP6D Grade 2 entry/office lever. For classrooms, the Dexter C1000 Grade 1 classroom lever is clutching and keyed.
15) I have a 2 inch thick door. Will the Kwikset 408CNL Carson work, or should I look elsewhere?
For thicker doors, peers that publish the range are the safer specification: the Falcon K101 Grade 1 passage lever covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 asylum Grade 1 covers 1-3/8 inch to 2 inch, the Hager 2510 Grade 2 passage lever covers 1-3/8 inch to 2 inch, and the Corbin Russwin CL3110 Grade 1 is built for 1-3/4 inch to 2 inch. The Kwikset 408CNL Carson has an adjustable 2-3/8 inch or 2-3/4 inch backset for standard bores.
16) For a behavioral health or patient room where a privacy lock cannot be used, what takes the place of the 408CNL Carson?
Asylum and institutional functions are specified there instead of privacy. The Dexter C1000 asylum (F87) is Grade 1 for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility lock with a ball knob and a conventional cylinder in Schlage C keyway. Both key from both sides rather than relying on an inside pushbutton like the Kwikset 408CNL Carson.
17) Are there square-rose alternatives to the round-rose Carson lever for a more contemporary interior?
Yes. The Bravura Tampa passage leverset uses square trim at Grade 2, while the Bravura Atlanta, Orlando, and Miramar passage leversets use round trim at Grade 2, the Miramar being offered in US4 satin brass. Design Hardware also offers flat lever passage sets - the J75 at Grade 2 and the X75 at Grade 1, both for 1-3/4 inch doors. The Kwikset 408CNL Carson is a traditional-style lever.
18) Which alternatives to the Carson privacy lever are non-handed so I do not have to specify door swing?
The Falcon B101 Grade 2 passage lever and Falcon K101 Grade 1 passage lever are both non-handed by design, and the Accentra 4601LN Grade 2 passage lever is a 4600 Series cylindrical set. By contrast, the Baldwin Estate 5103 half dummy levers must be ordered left hand or right hand. The Kwikset 408CNL Carson lever is reversible, so one part covers either swing.
