Weslock 009004N4NFR20 – Frequently Asked Questions

1) Do I have to know the backset before ordering the Weslock Mesa passage knob?
No. The latch adjusts between 2-3/8 and 2-3/4 inch backset, the two backsets used on residential doors, so you set it on site to whatever the existing bore gives you. That is what makes it a safe order for a property manager replacing knobs across doors that were not all drilled the same.
2) Can I drop a Weslock Mesa knob into a door that already has a knob in it without redrilling?
If the door is bored the standard way, yes. The Mesa passage set uses a 2-1/8 inch cross bore with a 1 inch edge bore, which is the standard residential prep, and the adjustable latch covers either backset. Measure the hole in the face of the door first; anything other than 2-1/8 inch needs a filler plate or a new door.
3) Will the Weslock Mesa passage knob latch into the strike plate that is already in my jamb?
The latch throws 1/2 inch, and it ships with a 2-1/4 by 1-3/4 inch radius corner full lip strike. If your jamb has a full lip strike with rounded corners, the new one drops into the same mortise. Square corner strikes are also available if the jamb is cut square. The lip matters on a wood jamb: it carries the latch over the edge of the trim instead of chewing it up.
4) Does a passage knob have any lock in it, and can I use one on a bathroom or bedroom door?
Passage means no lock at all. Both knobs turn free at all times, which is what you want on a hallway, a closet, or a pantry. It is the wrong choice for a bathroom or bedroom, where you need a privacy set with a push button inside. For those openings on the same job, the Pamex FTF Baron privacy knob or the Dexter C2000 privacy ball knob are non-keyed privacy sets in the same style of cylindrical trim.
5) Is a Weslock Mesa passage knob heavy duty enough for an apartment building or an office corridor?
It is a residential Grade 3 lockset in zinc alloy, built for a house or a condo interior rather than a commercial corridor. For a building with real traffic, step up: the Corbin Russwin CK4410 is a Grade 2 passage knob, and the CK4310 is Grade 1 and takes doors from 1-3/8 up to 2 inches. The Falcon X101 is another Grade 1 heavy duty passage knobset. Grade 1 is the top ANSI/BHMA cylindrical rating, Grade 3 the light-duty one.
6) Can I use a dummy knob in place of the Mesa passage knob on a closet door?
No. The Weslock 0900 Mesa is a passage set with a working latch that retracts when the knob turns. A dummy knob such as the Schlage A170 single dummy trim or the Cal-Royal BA40 has no latch at all and is surface mounted trim only - it will not hold a door closed. Use a dummy only on an inactive leaf or a door held by a ball catch or roller catch.
7) The bathroom door needs a lock but the hall doors do not - what matches the Mesa knob for a bedroom or bath?
The Weslock 0900 Mesa knob is a passage function with no key and no locking cylinder, correct for halls and closets. For a bedroom or bath opening you need a privacy function. The Pamex FTF Baron in privacy function is a Grade 3 knob for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal BER20 is a Grade 3 privacy knob for the same door thickness range with brass trim.
8) What is the difference between the Weslock Mesa passage knob and the Corbin Russwin CK4310 or CK4410 passage knobs?
The Corbin Russwin CK4310 is a Grade 1 Global knob passage/closet lock fitting doors 1-3/8 inch to 2 inch, and the CK4410 is the Grade 2 version fitting 1-3/8 inch to 1-3/4 inch. The Weslock 0900 Mesa is a Grade 3 residential passage knob for 1-3/8 inch to 1-3/4 inch doors with a square rose and adjustable 2-3/8 or 2-3/4 inch backset. If the door is thicker than 1-3/4 inch, the CK4310 is the one that covers it.
9) For a school or office closet that has to stay locked, what replaces a passage knob?
A passage knob like the Weslock 0900 Mesa is always free on both sides and cannot be locked. For a closet that must stay secured, the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, and the Sargent 8XG04 is the Grade 1 heavy duty storeroom/closet version with a 2-3/4 inch backset.
10) Can a Weslock Mesa passage knob go on a fire rated door?
For a rated opening, specify a lockset that carries a fire rating on its own listing. The Falcon W101 Grade 2 passage knob and the Falcon X101 Grade 1 passage knobset are both fire rated, and the X101 takes doors from 1-3/8 up to 2-1/4 inches.
11) Does the Weslock Mesa knob have a handing, or do I need to specify left or right?
Non-handed. One part works on a left or right hand door, so there is nothing to specify and nothing to get wrong on a bulk order. Field-reversible latches are the norm on residential bored locksets.
12) Can I use a passage knob on a back door if I still want it to lock?
Yes, paired with a deadbolt. The knob itself gives you the latch and the pull, and the deadbolt does the securing. That is a common way to do a service or back entry, and it keeps the keying in one cylinder instead of two.
13) What kind of latch faceplate comes with the Weslock Mesa knob, and can I get a drive-in?
Standard is a 1 by 2-1/4 inch radius corner faceplate. Square corner and drive-in versions are available instead. Drive-in is the one to ask for on a pre-bored door with no faceplate mortise cut, since it seats in the edge bore without routing.
14) What is the closest passage knob to the Weslock Mesa if I want the same thing from a different brand?
Straight swaps at the same duty level: the Pamex FTF Baron passage knob is Grade 3 for 1-3/8 to 1-3/4 inch doors, and the Kwikset 200P Polo passage knob comes with an adjustable round corner latch and round corner strike, which is the same install as the Mesa. Moving up a grade, the Dexter C2000 passage ball knob and the Arrow MK01 are both Grade 2 for the same door thickness range.
15) Is there a passage knob with a round rose instead of a square one?
Yes. The Weslock 0900 Mesa knob uses a square rose. For a round trim in the same passage function, the Bravura Albany and Bravura Lynchburg are Grade 2 passage knobsets with round trim, and the Bravura Dallas is a Grade 2 passage knobset with rectangle trim if you want a rectilinear look in a different proportion.
16) The Weslock Mesa comes in matte black and satin nickel - what if I need a brass passage knob?
The Weslock 0900 Mesa knob is offered in matte black and satin nickel. For a brass passage knob, the Bravura Dallas passage knobset is a Grade 2 set in US4 satin brass, and the Omnia 434/PA egg-shaped knob latchset is a passage function in solid brass with a 3 inch projection.
17) Is a Kwikset Polo passage knob the same thing as the Weslock Mesa passage knob?
They serve the same opening but they are not the same set. The Kwikset 200P Polo is a passage door knob supplied with a 6AL latch and RCS round corner strike, and the 200P-CP is the clear pack version with a round corner adjustable latch and round corner strike. The Weslock 0900 Mesa ships with a 1 inch by 2-1/4 inch radius corner faceplate and a 2-1/4 inch by 1-3/4 inch full lip radius strike, and its backset adjusts between 2-3/8 and 2-3/4 inch. If you are replacing into an existing strike mortise, match the strike shape before you swap brands.
18) I need a keyed knob for the same door style as the Mesa passage knob - what are the options?
The Weslock 0900 Mesa knob is non-keyed, so a keyed opening needs a different set. In Grade 3, the Cal-Royal BER00 is an entrance/office knob lock with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 400P-CP is a keyed entry Polo knob for the same thickness range, and the Pamex FTF Baron entrance/office is a Grade 3 keyed knob for 1-3/8 inch to 1-3/4 inch doors.
19) Is there a decorative passage knob for a period home instead of the Mesa square rose knob?
Yes. The Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Baldwin Estate 5000 Baltimore 2 inch knob with 5048 rose, a passage lock with 2-3/8 inch backset and full lip strike, both cover the same hall and closet function in a traditional profile. The Weslock 0900 Mesa is a square rose zinc alloy knob whose backset adjusts to either 2-3/8 or 2-3/4 inch, which matters if the existing bore is drilled to the deeper backset.
20) What finishes does the Weslock Mesa passage knob come in?
Two: matte black and satin nickel. Both are on the Mesa knob with the square rose trim, so the rose shape does not change between them. If you are matching knobs already on other doors in the unit, satin nickel is the one that pairs with most existing brushed hardware.
21) Are the mounting screws on the Weslock Mesa knob visible from the room side?
No. The screws are concealed, so the rose shows a clean face on both sides. It is the detail that separates it from a builder-grade knob where two screw heads sit on the interior rose.
