Kwikset KWI-462DL Delta Lever Storeroom Vestibule Lock with 6AL Latch and RCS Strike

No handing to specify. The Delta 462DL is universal handing and fits both right hand and left hand doors, so one part number covers every opening in the building. For a property manager buying a dozen at once, that removes the usual sorting problem at install time.

The Kwikset 462DL Delta is ANSI/BHMA Grade 3 with a storeroom/vestibule function - outside unlocked only while the key is turned, inside always free. For a heavier commercial storeroom opening, the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, fitting doors 1-3/8 inch to 1-3/4 inch, and the Hager 2580 with the Withnell lever is a Grade 2 storeroom cylindrical lock fitting doors 1-3/8 inch to 2 inch. Both keep the same storeroom keying behavior a stockroom or vestibule door needs while moving up the ANSI grade.

The Kwikset 462DL Delta is keyed storeroom/vestibule function, so it is the wrong choice for a door that stays free both sides. For passage duty, the Arrow GL01 is a Grade 2 non-keyed passage cylindrical lock with the Sierra lever for 1-3/4 inch to 2 inch doors, the Hager 2510 is a Grade 2 passage lever for 1-3/8 inch to 2 inch doors, and the Falcon K101 is a Grade 1 heavy duty passage lock with non-handed levers, fire rated, for 1-3/8 inch to 2-1/4 inch doors.

On the Kwikset 462DL Delta the outside lever is unlocked only while the key is turned, so it cannot be left open. An entrance/office function does what you are describing: 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, the Falcon B511CP6D is a Grade 2 medium duty entry/office cylindrical lever, and the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors.

The Kwikset 462DL Delta is a residential Grade 3 storeroom/vestibule lever with an adjustable 2-3/8 inch to 2-3/4 inch backset latch. For a commercial common-area storeroom, the Hager 2580 Withnell is a Grade 2 storeroom cylindrical lock for 1-3/8 inch to 2 inch doors and the Cal-Royal AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt. For institutional openings where both sides need key control, the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum function lock with a conventional cylinder in Schlage C keyway and the Dexter C1000 asylum is a Grade 1 F87 lock for 1-3/8 inch to 2 inch doors.

Two Grade 2 storeroom options sit a tier above it. The Hager 2580 with the Withnell lever is a Grade 2 storeroom cylindrical lock covering 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. Both keep the same behavior you want, outside always locked and key retracts, with heavier internal parts than a Grade 3 residential set.

No. On a storeroom function the outside lever never unlocks except while the key is held, so staff cannot leave a room open for the day. For a classroom you want a classroom function like the Dexter C1000 Classroom or the Cal-Royal AG03; for an office that gets locked and unlocked by the occupant, an entrance/office function such as the Falcon B511CP6D or the Hager 2525 entry lock makes more sense. Use the Kwikset 462DL where the door should be secure by default, like a supply room or a vestibule.

No. The Kwikset 462DL Delta keeps the outside lever locked at all times, unlocking only while the key is turned, with the inside always free. A classroom function lets the key lock and unlock the outside lever so it can be left in either state - the Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, and the Dexter C1000 classroom is a Grade 1 clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors. Choose classroom only if the outside lever needs to be left unlocked between periods.

You can if you want code access rather than a key. The Kwikset 462DL Delta uses a key on the outside lever. Keyless alternatives include the Lockey 2835 mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 inch to 2 inch, the Lockey 1150 heavy duty mechanical keypad lever set with adjustable backset for 1-1/8 inch to 2 inch doors, and the Delaney LP250 Grade 2 electronic keypad leverlock. These remove key management but also remove the ability to key the door alike with the rest of a Kwikset cylinder set.

Dummy and half-dummy levers mount the same trim but have no latch and no keyed function, so they cannot replace the keyed storeroom Kwikset 462DL Delta. Examples are the BEST 9K Series 1DT single dummy trim lever, Grade 1 non-keyed, the BEST 7KC Series single dummy trim, Grade 2 non-keyed, the Callan Bentley Grade 2 dummy lever, and the Baldwin Estate 5103 half dummy in left and right hand. Use those only on an inactive leaf or a closet face where nothing latches.

The Kwikset 462DL Delta is keyed storeroom function with the inside lever always free, which is not a privacy set. For a bed or bath door use a privacy function: the Hager 2540 with the Withnell lever is a Grade 2 privacy cylindrical lock for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a Grade 2 privacy cylindrical lock with a Tudor knob and a fire rating, and the Baldwin Estate 5103 privacy lever with the 5048 rose covers the decorative side.

Within the same ANSI/BHMA Grade 3 tier as the Kwikset 462DL Delta, the Master Lock BC Series RL01 is a Grade 3 keyed entry return style lever and the Callan Artino is a Grade 3 entrance leverset. The difference to watch is function: the 462DL is storeroom/vestibule, outside unlocked only while the key is turned, while both of those are entrance function, so the outside lever can be left unlocked for traffic.

Two: Bright Chrome and Satin Chrome. If the rest of your doors are on a satin nickel or brass program, these two chromes will not match, so pick the opening carefully or standardize the building on chrome.

The Delta 462DL is built with Microban antimicrobial protection in the finish, which inhibits the growth of stain and odor causing bacteria on the lever surface. It is a finish treatment, not a disinfectant, and it does not change how the lock operates. Worth noting on healthcare, hospitality, or multi-family touch points where hand contact is constant.

A screwdriver does it. The Delta 462DL is a cylindrical lockset that installs in a few minutes into a standard bored door prep, latch in the edge bore and strike on the jamb. No mortising, no specialty tooling.

The Kwikset 462DL Delta comes in bright chrome and satin chrome with the Delta lever style. If the opening calls for a more decorative trim with a keyed entry function, the Deltana Manchester 6201, Morant 6411 and Linstead 6431 levers are entry function and fit doors 1-3/8 inch to 2 inch, and the Deltana Claremont 5851 is also an entry lever. Note these are entry function rather than storeroom function, so the outside lever can be left unlocked.
