Kwikset 400P Polo Knob Entry Door Lock with 6AL Latch and RCS Strike

Yes. The 6AL latch on the 400P Polo entry knobset has an adjustable backset that covers both 2-3/8 inches and 2-3/4 inches, which are the two standard residential bore-to-edge dimensions. You do not have to specify the backset when ordering, and you do not need a different latch for a 2-3/4 inch prep.

Neither. The Polo 400P is reversible, so the same lock installs on a right-hand or left-hand door. For a property manager stocking spares across a building, that means one part number covers every swing.

Yes. The 6AL latch ships with two interchangeable faceplates, round corner and square corner, so it matches either existing jamb mortise without recutting. The kit also includes a full lip round strike and a round deadbolt strike.

It is a residential-duty lock. The 400P Polo carries an ANSI/BHMA Grade 3 certification and Kwikset lists it as a residential product, which suits apartment and house entry doors but not a high-traffic commercial opening. For commercial entrance duty look at a Grade 1 cylindrical knob such as the BEST 8K Series entrance lock or the Corbin Russwin CK4851, or a Grade 2 like the Dexter C2000 entry/office knob.

For a like-for-like residential keyed entry knob at the same certification level, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock that uses a Kwikset keyway, so it keys into the same key system family. The Master Lock BC01 is another Grade 3 keyed entry knob, in the BC Series with a biscuit knob shape. Callan also offers Grade 3 entrance knobsets in the Canova and Santo series. All four are keyed entry knobs at Grade 3 like the 400P Polo, differing mainly in knob shape and keyway.

The 400P Polo is a residential Grade 3 entry knob. For a commercial door, step up to a Grade 2 or Grade 1 cylindrical knob: the Dexter C2000 Series entry/office knob is Grade 2 and keyed, the Sargent 6G04 is a Grade 2 storeroom/closet knob with a single cylinder, and the BEST 8K Series entrance function single cylinder knob is Grade 1 heavy duty. The Corbin Russwin CK4851 entrance/office knob with conventional cylinder covers doors 1-3/8 inch to 2 inch thick. Note that storeroom function differs from entrance function - storeroom keeps the outside knob always locked, while the 400P uses an interior turn piece.

The 400P Polo is a residential entry knob with a latch adjustable from 2-3/8 inch to 2-3/4 inch backset to fit standard door preps. If the door is thicker than typical residential stock, look at knobs that state a wider thickness range: the Corbin Russwin CK4851 entrance/office knob and CK4310 passage knob both cover 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch. Deltana's 3381 and 6171 entry knobs also list 1-3/8 inch to 2 inch.

Entrance function. The outside knob is keyed and comes with two keys; the inside knob locks with a turn piece. Turn the interior piece to lock the outside knob, and the key retracts it from the exterior.

The 400P Polo is a keyed SmartKey entry knob on the Kwikset keyway. If you want a single key across a building, the Cal-Royal BER00 Grade 3 entrance knob is also supplied with a Kwikset keyway, so it can be worked into the same key system by a locksmith.

No. The Polo 400P is keyed entrance function, meant for entries and main doors. For a bedroom or bath you want privacy function, such as the Pamex FTF Baron privacy knob or the Dexter C2000 privacy knob, both Grade 3 and Grade 2 respectively. For a hall or closet with no locking at all, the Pamex FTF passage knob or Bravura Albany passage knobset is the right choice.

Same grade and function alternatives include the Callan Canova and Callan Santo Grade 3 entrance knobsets, the Delaney Belton, Galway and Olivia Grade 3 entrance knobs, the Master Lock BC Series Biscuit keyed entry knob, and the Pamex FTF Baron entrance/office knob, which lists a 1-3/8 to 1-3/4 inch door thickness range. All are keyed entry knobs in the same residential duty class rather than heavier commercial locks.

No. The 400P Polo is a keyed entrance knobset with a latch and strike - it actually latches and locks the door. Dummy knobs such as the Schlage A170 single dummy trim, the BEST 6K Series single dummy trim, the Cal-Royal BA40 Barrington dummy knob, and the Bravura Biloxi dummy knobset have no latch mechanism at all; they are surface-mounted pulls for inactive leaves and closet doors. They will not secure an entry door.

The 400P Polo ships as an entry knobset with the 6AL latch and RCS strike, and it does include a round deadbolt strike so a deadbolt can be added above it. If you would rather buy both pieces together, the Schlage Residential F500 Plymouth with Georgian knob is sold as a combo pack with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch. That gets knob and deadbolt keyed alike out of one box.

The 400P Polo is a keyed entry knob, so for halls, closets or bedrooms you want a passage or privacy knob instead. Pamex offers the Grade 3 Baron knob in passage (FTF30) and privacy (FTF10) functions for doors 1-3/8 inch to 1-3/4 inch. Cal-Royal BER20 is a Grade 3 privacy knob with brass trim over the same door thickness range. Bravura Albany and Lynchburg are Grade 2 passage knobsets with round trim. For a bath or bedroom that needs to lock without a key, the privacy versions are the ones to take.

The 400P Polo is a residential Grade 3 entry knobset and no fire rating is carried for it, so for a labeled opening specify hardware that states one. The Falcon W101 Grade 2 cylindrical knob is fire rated and the Falcon X101 Grade 1 knobset with interchangeable core is fire rated as well - both are passage function, so if the opening also needs to lock, pair the rated series with a keyed function from that line.

The 400P Polo is keyed and ships with two keys. If you want to get rid of key management entirely on that opening, the Lockey 3830 is a mechanical keyless combination knob lock with auto-locking passage function, fitting doors 1 3/16 inch to 2 inch. It is a code-entry lock rather than a cylinder lock, so there is no key to rekey or reissue when tenants or staff change.

The 400P Polo is entrance function: the outside is keyed and the inside has a turn piece, so anyone inside can lock or unlock the door by hand. A classroom knob such as the Dexter C2000 Series classroom cylindrical ball knob, Grade 2 and keyed for 1-3/8 inch to 1-3/4 inch doors, has no inside turn piece at all - it is locked and unlocked only by key from the outside so occupants cannot leave it secured or unsecured by accident. Choose by whether you want the occupant to control the lock.

A screwdriver. On a door already bored for a standard cylindrical lock, the 400P goes in with nothing else, and the adjustable latch means no boring change for a 2-3/8 or 2-3/4 inch backset.

Yes, the Polo 400P is listed with Microban protection on the finish. That is a point of interest for multi-family and healthcare-adjacent properties where touched surfaces get specified.

The 400P Polo is a Grade 3 residential entry knob sold in Venetian Bronze, Satin Nickel, Satin Chrome and Antique Brass. For fleet standardizing, Sure-Loc offers the Bergen round knob in a 6-pack with adjustable backset. If the portfolio is mixed-use and you want one higher-grade standard across units and common areas, Callan Edgewood and Callan Roland are Grade 2 entrance knobsets, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom knob with a 2-3/4 inch backset for the back-of-house doors.

The 400P Polo is a traditional-style knob available in Venetian Bronze, Satin Nickel, Satin Chrome and Antique Brass. If you want a more decorative solid-brass look on the same entry function, Deltana offers the 3381 Egg Knob entry and the 6171 Round Knob entry, both for doors 1-3/8 inch to 2 inch, and the 6901 Portland Knob entry for 1-3/8 inch to 1-3/4 inch doors. Delaney also lists Grade 3 entrance knobsets in the Belton, Galway and Olivia designs.
