Weslock 00640JNJNSL23 – Frequently Asked Questions

1) Will the Weslock 0640 Julienne knob fit a door already bored for a standard cylindrical lock?
If the door has a 2-1/8 inch cross bore and a 1 inch edge bore, the 0640 Julienne knob drops straight in. That is the standard residential bored prep, so most existing knob or lever openings take it without redrilling. The latch is adjustable between 2-3/8 and 2-3/4 inch backset, so you do not need to know which backset the door was drilled for before you order.
2) What door thickness does the Weslock 0640 keyed entry knob work on, and what do I order for a thicker door?
Standard build covers 1-3/8 to 1-3/4 inch doors, which is most residential entry and interior door stock. For a heavier door, the 0640 is orderable in a thick-door configuration covering 1-3/4 to 2-1/4 inches. Door thickness is a required selection when you order, so measure the door edge before you place it.
3) Can I get several Weslock Julienne entry knobs keyed alike so one key runs the whole house?
Yes. The 0640 Julienne is offered keyed different as standard or keyed alike at no charge, and there is a key code field on the order if you need it cut to an existing code. It runs a 5 pin cylinder on the Weslock keyway, so keying alike works across Weslock entry hardware sharing that keyway, not across a Kwikset or Schlage keyway. A landlord standardizing a building should order every opening in the same batch keyed alike.
4) Will the strike on the Weslock 0640 cover the mortise cutout my old strike left in the jamb?
The 0640 ships with a 2-1/4 inch full lip strike in both radius and square corner versions, so you pick the one matching the jamb cutout instead of chiseling a new one. The latch faceplate is 1 x 2-1/4 inches and also comes in removable radius and square, meaning the same lock covers a rounded-corner factory prep or a square-corner chiseled prep on the door edge.
5) What is the closest keyed entry knob equivalent to the Weslock 0640 Julienne if a different brand is required?
The Kwikset 400P-CP Polo keyed entry knob is the nearest match in form and function. It is a Grade 3 entrance knob with a round corner adjustable latch and round corner strike, and it fits doors 1-3/8 inch to 1-3/4 inch. The Weslock 0640 Julienne is a single cylinder keyed entry knob with an adjustable 2-3/8 or 2-3/4 inch backset latch, a 2-1/4 inch full lip strike in radius and square, and it adjusts to door thickness from 1-3/8 to 1-3/4 inch with an optional kit to 2-1/4 inch. Both are residential-duty keyed knobs; the Weslock carries a 5 pin cylinder in the Weslock keyway, so the two will not key alike to each other.
6) The Weslock 0640 Julienne is residential grade - what keyed knob holds up on a commercial opening with heavy traffic?
For heavy-duty commercial service, the BEST 8K Series entrance function knob lock is a Grade 1 heavy duty single cylinder knob, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset. The Weslock 0640 Julienne is a residential keyed entry knob in the Traditionale collection with all brass knobs and rosettes. On an entrance opening where the door should stay unlocked when the button is not set, the BEST 8K entrance function matches the 0640's function; the Sargent 8XG04 storeroom function keeps the outside knob locked at all times and requires a key on every entry.
7) Do the Emtek and Omnia knobsets work as a substitute for the Weslock 0640 Julienne keyed entry knob?
No. The Emtek Arts and Crafts Hammered Egg knobset and the Emtek Classic Brass Crystal Georgetown and Providence knobsets are dummy pairs, the Omnia 434/0 and Omnia 458/0 are single dummy latchsets, and the Omnia 434/PA is a passage latchset. Dummy trim has no latch and does not operate; it mounts to the face of the door as a pull. The Weslock 0640 Julienne is a keyed entry knob with a single cylinder and an adjustable 2-3/8 or 2-3/4 inch backset latch, so none of those parts secure an opening.
8) The Weslock 0640 Julienne uses a Weslock keyway - what keyed knob can be ordered to match an existing Kwikset key system?
The Cal-Royal BER00 entrance/office Grade 3 knob lock is supplied with a Kwikset keyway and fits doors 1-3/8 inch to 1-3/4 inch. The Weslock 0640 Julienne carries a 5 pin cylinder in the Weslock keyway, so it will not accept a Kwikset key. Both are single cylinder keyed knobs for an entrance opening, and the 0640 can be ordered keyed alike within its own keyway for a group of doors.
9) Is a Weslock Julienne knob entry lock strong enough for an apartment or office door?
The 0640 is a residential-rated product. Weslock states it exceeds ANSI A156.2 Grade 2 lock standards, which suits a house, a condo unit, or a low-traffic side entrance. For a commercial opening taking constant use, look at a heavy duty Grade 1 knob lock like the BEST 8K Series entrance function or the Corbin Russwin CK4851; both are entrance function keyed knob locks built for that duty.
10) What is the difference between the Weslock 0640 keyed entry and a privacy or passage knob?
Keyed entry means a key operates the outside knob and a push button in the interior rosette locks it from inside. Use it on a front door, a side door, or a garage-to-house door. A bedroom or bathroom wants privacy instead, with a push button and no key, and a hall or closet wants passage, which never locks at all. Weslock's Traditionale range covers all three functions, and among other brands the Dexter C2000 line offers the same knob in entry, privacy and passage versions.
11) If someone is inside, do they need to unlock the Weslock 0640 before they can get out?
No. The 0640 uses a panic-proof keylock, so one turn of the interior knob unlocks and opens the door in a single motion. That matters on a bedroom-side or unit entry door where an occupant needs to leave fast without hunting for the button or a key.
12) What is a good alternative to a Weslock Julienne entry knob if I need a wider door thickness range?
The Weslock 0640 covers 1-3/8 to 1-3/4 inches standard and up to 2-1/4 inches in the thick-door build, which handles almost any residential door. If you want a keyed knob from another brand on a thicker opening, the Corbin Russwin CK4851 entrance/office cylindrical knob covers 1-3/8 to 2 inches and the Falcon X101 covers 1-3/8 to 2-1/4 inches, though the X101 is passage function and does not key. Among direct residential keyed knob alternatives, the Kwikset 400P-CP Polo keyed entry is Grade 3 for 1-3/8 to 1-3/4 inch doors.
13) Does the Weslock 0640 come with the latch and strike, or do I order those separately?
Both are included. The set ships with an adjustable latch, faceplates in radius and square, and a 2-1/4 inch full lip strike in radius and square. Nothing else is needed for a door already bored 2-1/8 inch cross hole and 1 inch edge hole beyond a screwdriver.
14) Which knob matches the Weslock 0640 Julienne on a bedroom or bathroom door that should not take a key?
For a privacy opening, the Baldwin Estate 5077 Bethpage privacy knob and the Deltana 6112 St. Thomas privacy knob both cover bed and bath, with the Deltana 6112 fitting doors 1-3/8 inch to 2 inch. The Pamex FTF Baron privacy knob is a Grade 3 privacy lockset for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C2000 privacy ball knob is Grade 2 for the same thickness range. The Weslock 0640 Julienne is a keyed single cylinder entry knob, so it is the wrong function for an interior bed or bath door.
15) What should be used on a hall or closet door where the Weslock 0640 Julienne keyed entry knob is not needed?
A passage knob is the right part where no locking is wanted. The Kwikset 200P-CP Polo passage knob comes with a round corner adjustable latch and round corner strike, the Dexter C2000 passage ball knob is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, and the Bravura Albany passage knobset is a Grade 2 round trim option. The Weslock 0640 Julienne is a keyed entry knob with a 5 pin cylinder in the Weslock keyway and push button locking in the rosette, which a closet does not use.
16) Which keyed entry knob offers a wider backset range than the Weslock 0640 Julienne for a mixed set of door preps?
The Weslock 0640 Julienne ships with an adjustable latch set to 2-3/8 or 2-3/4 inch backset and fits doors prepared with a 2-1/8 inch cross hole and 1 inch edge bore, so one part covers both common preps. Among other keyed knobs, the Kwikset 400P-CP includes a round corner adjustable latch, while the Corbin Russwin CK4851 entrance/office knob is a fixed-specification Grade 1 lock for doors 1-3/8 inch to 2 inch. Where the openings on a building mix 2-3/8 and 2-3/4 inch backsets, an adjustable latch avoids sorting parts per door.
17) Is a fire rated knob lock needed instead of the Weslock 0640 Julienne on a rated corridor door?
Where a fire rating is required, the Falcon W101 Grade 2 cylindrical knob lock is a fire rated medium duty passage/closet latch with a 2-3/4 inch backset, and the Falcon X101 Grade 1 heavy duty knobset with interchangeable core is fire rated for doors 1-3/8 inch to 2-1/4 inch. The Weslock 0640 Julienne is a residential keyed entry knob in the Traditionale collection, so for a rated opening the Falcon parts are the ones to specify - noting both are passage function and carry no key.
18) What is the difference between the Weslock 0640 Julienne keyed entry knob and a storeroom function knob like the Sargent 6G04?
The Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, and the Imperial USA ED-BKL580 is knob trim in storeroom function. On a storeroom lock the outside knob stays locked and a key is required for every entry. The Weslock 0640 Julienne is a single cylinder keyed entry knob with push button locking in the rosette, so occupants can leave it unlocked for normal traffic and set the button when the door should secure. Its panic-proof design means one turn of the interior knob unlocks and opens the door.
19) Which keyless option replaces a Weslock 0640 Julienne keyed entry knob where keys should not be issued?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors 1 3/16 inch to 2 inch. It opens on a code instead of a key. The Weslock 0640 Julienne is a single cylinder keyed entry knob with a 5 pin cylinder in the Weslock keyway, and it can be ordered keyed alike or keyed different. The Lockey removes key control from the opening entirely, which is the deciding difference for shared access points.
20) For a classroom door, does the Weslock 0640 Julienne entry knob work or is a classroom function required?
A classroom opening calls for a classroom function lock. The Dexter C2000 Series classroom cylindrical ball knob is Grade 2, keyed, non-clutching, for doors 1-3/8 inch to 1-3/4 inch, and the Sargent 28C-KNOB is exit device trim with knob and rose in classroom function for 1-3/4 inch doors. The Weslock 0640 Julienne is a residential single cylinder keyed entry knob with push button locking in the rosette, which lets anyone inside set the lock - the behavior classroom function is designed to prevent.
21) Are the mounting screws visible on the Weslock Julienne knob after installation?
No. Screws come pre-installed and hide behind a snap-on rosette, so the finished face of the door shows no fasteners. The knobs also come off during install to keep from scratching the finish while you are working the trim, which is worth knowing if you are hanging a run of doors in one day.
22) Can I match the Weslock 0640 Julienne knob to other doors in the same house?
The Julienne knob is part of the Weslock Traditionale collection, so the same knob design and rosette carry across the other Traditionale functions for the interior and closet doors on the same floor. Order the entry function where you need a key and the non-keyed functions elsewhere, all in the same finish, and the openings match visually.
23) What non-keyed knob pairs with a Weslock 0640 Julienne keyed entry knob on the same run of doors?
For the openings on the run that do not need a key, the Arrow MK01 and Arrow RK01 are Grade 2 passage cylindrical knob locks for doors 1-3/8 inch to 1-3/4 inch, the Corbin Russwin CK4410 is a Grade 2 passage/closet knob for the same range, and the BEST 6K Series single dummy trim is a Grade 2 medium duty dummy for a door leaf that does not latch. The Weslock 0640 Julienne handles the keyed entrances with its single cylinder, and it fits the same 2-1/8 inch cross bore standard bored prep.
24) Which keyed entry knobs besides the Weslock 0640 Julienne suit a traditional interior look across a set of doors?
Within traditional-styled keyed entry knobs, the Callan Canova and Callan Santo are Grade 3 entrance knobsets and the Callan Edgewood and Callan Roland are Grade 2 entrance knobsets. The Delaney Belton, Galway and Olivia are Grade 3 entrance knobsets, and the Master Lock BC Series biscuit knob is a Grade 3 keyed entry. The Weslock 0640 Julienne is a Traditionale collection knob with all brass knobs and rosettes, offered in oil rubbed bronze and satin nickel, and its concealed installation screws sit behind a snap-on rosette.
