Kwikset 300DL-26D – Frequently Asked Questions

1) Does the Kwikset 300DL Delta privacy lever work with a 2-3/8 inch backset or a 2-3/4 inch backset?
Both. The 300DL ships with the 6AL adjustable latch, which sets to either 2-3/8 or 2-3/4 inches, so you don't have to know the backset before you order. Measure from the door edge to the center of the bore hole on the door you're replacing and set the latch to match.
2) Is the Kwikset Delta privacy lever handed, or will one part number cover both left and right hand doors?
One part number covers both. The Delta 300DL is reversible for left- and right-hand doors, so a property manager stocking replacements for a building only has to carry one lever per finish rather than a left and a right.
3) Can you unlock a Kwikset 300DL privacy lever from the outside if a child locks themselves in the bathroom?
Yes. The privacy function locks with a turn button on the inside, and the outside lever has an emergency release you trip with a small tool or pin. That is the whole reason a privacy set goes on a bed or bath door instead of a keyed entry lock.
4) Is the Kwikset 300DL rated for a commercial building or apartment corridor doors?
It's a residential lock, ANSI/BHMA Grade 3, and Kwikset lists it for interior bedroom and bathroom doors. For multi-family unit interiors or light residential turns it's appropriate. For a commercial opening or a heavily used institutional restroom, step up to a Grade 1 or Grade 2 privacy set like the Arrow MK02-TA or the Hager 2540 with the Withnell lever.
5) What is the closest equivalent to the Kwikset 300DL Delta privacy lever from another brand?
For another privacy-function lever set, the Baldwin Estate 5103 Privacy Lever with 5048 Rose is the direct functional match - both are privacy/bed/bath levers for interior doors. The 300DL Delta is a residential Grade 3 lever with a 6AL adjustable latch covering 2-3/8 inch and 2-3/4 inch backsets and an RCS round corner strike. The Baldwin 5103 is an Estate-collection lever on a 5048 round rose.
6) I need a privacy lever for a commercial restroom instead of a bedroom. What should I use?
The Kwikset 300DL Delta is a residential-rated privacy lever set. For a commercial opening, the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever and a 1-3/8 inch to 2 inch door thickness range. If a knob is acceptable rather than a lever, the Arrow MK02-TA is a privacy/bed/bath cylindrical lock with a Tudor knob that carries a fire rating and a 1-3/4 inch to 2 inch door thickness range.
7) What should I put on a high-traffic door where a Grade 3 residential lever is not enough?
The Kwikset 300DL Delta carries ANSI/BHMA Grade 3 certification for residential use. Where a heavier cycle rating is required, the Falcon K101 is a Grade 1 heavy duty non-handed passage cylindrical lock, fire rated, with a 1-3/8 inch to 2-1/4 inch door thickness range, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever rated for 1-3/4 inch to 2 inch doors. Note both are passage rather than privacy function.
8) Can I use the Kwikset 300DL Delta on a door that needs a key?
No. The 300DL Delta is a non-keyed privacy lever - it locks from the inside with a turn button and releases from the outside with a tool for emergencies. For a keyed opening in a similar residential grade, the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors, and the Master Lock BC Series RL01 is a Grade 3 return style keyed entry leverset.
9) My patient room doors need a lock that cannot be locked from inside. Is the 300DL Delta appropriate?
No. The 300DL Delta is a privacy function lever specifically designed to be locked from the inside, which is the opposite of what a behavioral health or utility opening calls for. Asylum function is the correct choice: the Dexter C1000 Series asylum lock (F87) is Grade 1 for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility cylindrical lock with a ball knob and conventional Schlage C keyway cylinder.
10) What strike comes with the Kwikset Delta 300DL, and will it fit my existing frame prep?
It comes with the RCS round corner strike. That drops straight into a frame already routed for a radius-corner strike, which is what most residential metal and pre-hung wood frames use. If your jamb is mortised for a square corner strike plate, the round corner plate will leave a gap at the corners and you'll want to file the mortise or use a square strike instead.
11) Does the Kwikset 300DL take a key, and can it be keyed to match my other locks?
No key. The 300DL is a non-keyed privacy set, so there is no cylinder and nothing to key alike. If you need a bedroom or office door that keys into an existing system, you want an entry or office function lock instead, such as the Cal-Royal AG00 entrance lever in a 6-pin Schlage C keyway.
12) I need passage levers for closets and hall doors to match these bathroom locks. What pairs with the Kwikset Delta?
The 300DL is the privacy version of the Delta collection, so it's the bed and bath door of the set. For closets and halls you want a passage function lever in the same Delta trim so the building reads consistent. If you're matching by look rather than by brand, Callan's Asheville Grade 3 passage lever in Satin Nickel sits at the same grade level for residential work.
13) Is the Kwikset 300DL Delta the right lever for a hallway or closet door?
No - the 300DL Delta is a privacy lever with an inside turn button, which a hall or closet door does not need. For those openings use a passage lever such as the Callan Asheville, a Grade 3 passage leverset, or the Bravura Atlanta passage leverset with round trim in Grade 2. Both are non-latching-lock passage function and pair well beside a 300DL on the bedroom door.
14) Do I need to order a left-hand and right-hand version of the Kwikset 300DL Delta?
No. The 300DL Delta is reversible and installs on both left- and right-hand doors, so one part number covers the whole job. Some comparable levers are handed and do require you to specify - the Baldwin Estate 5103 half dummy, for example, is sold as separate left hand and right hand parts. Non-handed alternatives include the Falcon B101 Grade 2 passage lever and the Falcon K101 Grade 1 passage lock.
15) I need keyless entry on an interior door instead of a turn-button privacy lock. What are the options?
The Kwikset 300DL Delta locks only with an inside turn button and has no code or key entry. For pushbutton access, 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 Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for 1-1/8 inch to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock if you want a powered keypad rather than mechanical.
16) What finishes does the Kwikset 300DL Delta lever come in?
Four: Venetian Bronze, Satin Nickel, Bright Chrome, and Satin Chrome. Satin Nickel and Venetian Bronze are the usual matches for existing residential trim packages; Bright Chrome and Satin Chrome read cooler and are the ones to pick if the rest of the door hardware is polished or brushed chrome.
17) What does the Microban feature on the Kwikset Delta lever actually do on a bathroom door?
Microban is built into the lever's finish as an antimicrobial treatment. It's a finish-level feature, which is why it turns up most often on bath and bedroom hardware where hands are on the lever constantly. It doesn't change the mechanical function or the Grade 3 rating.
18) Is the Kwikset 300DL Delta a lever or a knob, and does that matter for accessibility?
It's a lever, not a knob. Levers are what you want on interior doors where someone may not be able to grip and twist a knob. If you specifically want a knob privacy set for a residential bath, the Arrow MK02-TA is a privacy knob with a Tudor design.
19) What tools do I need to install the Kwikset 300DL, and can maintenance staff do it without a locksmith?
A screwdriver. It's a cylindrical lockset going into a standard bored door prep, the latch adjusts to the backset on the door, and the levers are reversible, so there's no handing decision and no special tooling. Kwikset publishes an installation guide for the Delta lever set.
20) I want a matching lever on a door with no latch. What pairs with the Kwikset 300DL Delta?
A dummy lever is what goes on a non-latching door such as a closet slab or an inactive leaf. The Callan Bentley is a Grade 2 dummy lever, the BEST 7KC Series 1DT is a Grade 2 medium duty single dummy trim cylindrical lever, and the Baldwin Estate 5103 half dummy is offered in left hand and right hand versions. The 300DL Delta itself is a privacy lever and is not offered as a dummy.
21) What is a more decorative alternative to the Kwikset 300DL Delta for an interior door?
The 300DL Delta is a traditional-style lever from the Delta collection, offered in Venetian Bronze, Satin Nickel, Bright Chrome, and Satin Chrome. For a more ornate look, the Baldwin Estate 5103 privacy lever uses the 5048 rose, and Emtek offers decorative leversets including the Arts and Crafts and Hammered levers and the Classic Brass Cortina lever, though those Emtek trims are dummy pairs rather than privacy function.
