Weslock 03710I1I1SL20 – Frequently Asked Questions

1) Will the Weslock 3710 Impressa privacy knob fit a 1-3/8 inch interior door, or is it only for 1-3/4?
Both. The 3710 Impressa adjusts across a 1-3/8 inch to 1-3/4 inch door thickness range as standard, which covers the older 1-3/8 inch interior doors and modern 1-3/4 inch stock. If your doors are thicker, there is a second door thickness option covering 1-3/4 inch to 2-1/4 inch, and that choice is made when you order.
2) Do I have to know my backset before ordering the Weslock 3710 privacy knob?
No. The latch that comes with the 3710 Impressa is adjustable and covers both 2-3/8 inch and 2-3/4 inch backsets, with removable faceplates, so one part covers either bore location. Those are the two backsets you will find on residential doors, so you can measure at install rather than at the order form.
3) What door prep does a Weslock Impressa knob need? Can I put it in an existing knob hole?
It drops into standard bored prep: a 2-1/8 inch cross bore in the face of the door and a 1 inch hole in the edge. That is the same prep almost every cylindrical knob is cut for, so if you are pulling out an existing knob lock, measure the face hole. If it is 2-1/8 inch, the Impressa goes straight back in with no new boring.
4) Is the Weslock 3710 a keyed lock or just a bathroom push-button?
Push-button only, no key. The 3710 is a privacy function knob for bedroom and bath doors: you push the button on the inside knob to lock, and the outside has a small emergency release pin so the door can be opened from the hall in a hurry. It is non-keyed, so it is the wrong choice for an exterior door or anything you need to secure with a key.
5) What should I use instead of the Weslock 3710 privacy knob on a commercial corridor or classroom door?
The Weslock 3710 Impressa is catalogued for residential use at Grade 2. For a commercial opening, the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset and single cylinder, and the BEST 8K Series is a Grade 1 heavy duty entrance function knob lock with a single cylinder. For a classroom door specifically, the Dexter C2000 Series classroom knob is a Grade 2 keyed classroom function for doors 1-3/8 inch to 1-3/4 inch. Those are keyed functions, where the 3710 is non-keyed privacy, so they answer a different security need on the door as well as a different duty level.
6) Which knob looks like the Weslock 3710 privacy knob but will not lock a bathroom door?
Passage and dummy knobs share the same look and often the same rose but have no locking mechanism. The Dexter C2000 Series passage knob is a Grade 2 non-keyed passage/hall/closet knob, the Pamex FTF30 is the Grade 3 Baron knob in passage function, and the Corbin Russwin CK4410 is a Grade 2 non-keyed passage/closet lock. Dummy trim goes further and has no latch at all - the Schlage A170 is single dummy trim, and the BEST 6K Series single dummy trim is a Grade 2 medium duty dummy. The Weslock 3710 Impressa is the privacy/bed/bath function with a push-button lock in the interior rosette and an emergency-release pin outside, which is what a bedroom or bathroom door needs.
7) What privacy knob works on a door thicker than the Weslock 3710 Impressa handles?
The Deltana 6112 St. Thomas privacy knob covers doors from 1-3/8 inch to 2 inch as standard. The Weslock 3710 Impressa fits 1-3/8 inch to 1-3/4 inch in its standard build and is offered with an optional door thickness up to 2-1/4 inch, so on a thick door the choice is between ordering the 3710 in the thicker configuration or moving to the Deltana 6112, which reaches 2 inch without a separate option.
8) Which knob lock should I specify instead of the Weslock 3710 Impressa on a fire rated door?
The Falcon X101 is a heavy duty Grade 1 cylindrical passage knobset with an interchangeable core, carries a fire rating, and covers doors 1-3/8 inch to 2-1/4 inch. The Falcon W101 is a Grade 2 medium duty cylindrical knob lock in passage/closet function with a 2-3/4 inch backset and is also fire rated. Both are passage function rather than the privacy/bed/bath push-button of the Weslock 3710 Impressa, so on a fire rated opening that still needs to lock you are matching function and rating separately.
9) Will the Weslock Impressa strike work with my existing door frame mortise?
It ships with a round corner full lip strike. Round corner is the common cut on prefinished residential jambs, and the full lip wraps the jamb edge to protect the wood where the latch rides. If your frame is already prepped for a square-corner strike, the round corner plate will not sit in that mortise without recutting the jamb.
10) I need matching hall and closet knobs to go with a Weslock 3710 privacy set. What do I order?
The 3710 is privacy function only, so it covers bedrooms and baths. Hall and closet doors need a passage knob, which has no locking at all, and a closet with no swing may only need a dummy knob. If you are not matching the Impressa style exactly, Grade 2 passage knobs from Arrow (MK01 or RK01) and Corbin Russwin (CK4410) cover the same 1-3/8 to 1-3/4 inch doors.
11) Does the Weslock 3710 knob need to be ordered for a left or right hand door?
No handing to specify. The 3710 Impressa is a cylindrical bored lockset with a knob on each side, so it works on either swing. The only ordering decision besides finish is the door thickness range, which is a required choice: standard 1-3/8 to 1-3/4 inch, or the 1-3/4 to 2-1/4 inch build.
12) How does the Baldwin Estate 5000 Baltimore privacy knob compare with the Weslock 3710 Impressa?
The Baldwin Estate 5000 Baltimore is a preconfigured privacy lock built around a 2 inch Baltimore knob on a 5148 rose, supplied with a 2-3/8 inch backset and a full lip strike. The Weslock 3710 Impressa is also a privacy lock shipped with a round corner full lip strike, but its latch is adjustable to either a 2-3/8 inch or 2-3/4 inch backset with removable faceplates. That adjustability is the working difference for anyone who has not measured the bore before ordering, since the Baldwin comes fixed at 2-3/8 inch. Baldwin's other privacy knob, the Estate 5077 Bethpage on the R027 rose, is the same privacy/bed/bath function in a different knob shape.
13) Can I put a keyed knob in place of the Weslock 3710 Impressa privacy knob on the same door prep?
Yes, in the sense that these are all cylindrical knob locks in a standard bored door. The Weslock 3710 Impressa needs a 2-1/8 inch cross bore and a 1 inch edge hole and is non-keyed. Keyed alternatives on the same style of prep include the Cal-Royal BER00 entrance/office Grade 3 knob with a Kwikset keyway for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 400P-CP Polo keyed entry knob at Grade 3 with a round corner adjustable latch and round corner strike for the same thickness range, and the Pamex FTF-00 Baron knob in Grade 3 entrance/office function. Going keyed changes the door from a bed and bath push-button to a lock that needs a key from outside, so it suits an office or exterior-adjacent door rather than a bathroom.
14) What finishes does the Weslock Impressa 3710 privacy knob come in?
Two: Satin Nickel and Oil Rubbed Bronze, both on the Impressa knob with the rectangular rose. If you are standardizing a whole unit or a floor of a building, those are the finishes to plan around; there is no polished brass or black option in the 3710 Impressa.
15) Will the screws show on a Weslock Impressa knob after install?
No, the mounting screws are concealed behind the rose, and the knobs come off the spindle for installation so you are not dragging the finished knob against the door face while you set the screws. The rosettes are zinc die-cast.
