Weslock 01740ININSL23 – Frequently Asked Questions

1) What door thickness does the Weslock 1740 knob lock work on, and what if my door is thicker than 1-3/4 inch?
Standard build covers 1-3/8 to 1-3/4 inch doors. For a thicker slab there is a second door thickness option covering 1-3/4 to 2-1/4 inch, and it is selected when ordering, not swapped in later. A 1-3/4 inch door is the common commercial and solid-core exterior thickness and 1-3/8 the usual older interior one, so most openings take the standard version; measure the edge before you pick.
2) Can I get several Weslock Impressa entry knobs keyed alike so one key runs all the doors?
Yes. Keying is chosen at the time of order: keyed different is the standard, and keyed alike is available at no charge so a set of doors shares one key. There is also a key code field if you need the locks cut to a specific existing code. The cylinder is a 5 pin using the Weslock keyway, so a keyed alike group has to be all Weslock, not mixed with another brand's knobs.
3) Is the Weslock 1740 Impressa knob rated for a commercial building or apartment corridor?
It is a residential lock, built to ANSI A156.2 Grade 2. For a leasing office, corridor, or anything on a commercial maintenance schedule, step up to a Grade 1 cylindrical entrance knob such as the BEST 8K Series entrance single cylinder heavy duty knob lock, or the Corbin Russwin CK4851 entrance/office cylindrical knob. Those are built for the cycle counts a commercial opening sees.
4) What is the closest alternative to the Weslock 1740 keyed entry knob if I want a different brand?
For a like-for-like residential keyed entry knob, the Kwikset 400P-CP Polo keyed entry is the nearest match: Grade 3, 1-3/8 to 1-3/4 inch doors, with an adjustable round corner latch and round corner strike, same as the Weslock arrangement. Stepping up instead of across, the Callan Edgewood is a Grade 2 entrance knobset and the Dexter C2000 entry/office knob is Grade 2 for 1-3/8 to 1-3/4 inch doors. One thing that does not carry over: none of those use the Weslock keyway, so they will not key alike with an existing Weslock system.
5) What is a comparable keyed entry knob to the Weslock 1740 Impressa if I need a Grade 2 lock?
The Weslock 1740 Impressa is an entrance-function knob with a single-cylinder keyed knob on a 5 pin Weslock keyway. For a Grade 2 keyed entry knob from another maker, the Callan Edgewood (CLN-G2KE1001) is a Grade 2 entrance knobset, and the Dexter C2000 Series entry knob (DEX-C2000-ENTR-KNB) is a Grade 2 entry/office cylindrical ball knob, keyed, non-clutching, fitting doors 1-3/8 inch to 1-3/4 inch. The Weslock covers the same 1-3/8 inch to 1-3/4 inch door thickness range with its standard package.
6) I need a keyed knob for a commercial corridor, not a house. What should I use instead of the Weslock 1740?
The Weslock 1740 Impressa is a residential entrance knob meeting ANSI A156.2 Grade 2. For heavier commercial traffic, the BEST 8K Series (BEST-8K-AB) is a Grade 1 heavy duty entrance-function single cylinder knob lock, and the Corbin Russwin CK4851 (COR-CK4851-KEYED) is a Grade 1 entrance/office cylindrical lock with a Global knob and conventional cylinder that fits doors 1-3/8 inch to 2 inch. Sargent's 8XG04 (SGT-8XG04) is a Grade 1 heavy duty storeroom/closet single cylinder knob with a 2-3/4 inch backset, for openings that must stay locked with a key required from outside at all times.
7) Is the Kwikset 400P Polo the same thing as the Weslock 1740 Impressa?
Both are keyed entry knobs. The Kwikset 400P Polo (KWI-400P) is an entrance-function knob supplied with a 6AL latch and an RCS round corner strike; the clear-pack 400P-CP (KWI-400P-CP) is Grade 3 with a round corner adjustable latch and round corner strike, for doors 1-3/8 inch to 1-3/4 inch. The Weslock 1740 Impressa is an entrance knob meeting ANSI A156.2 Grade 2, keyed to a 5 pin Weslock keyway with a round corner full lip strike and an adjustable latch that sets to 2-3/8 inch or 2-3/4 inch backset. If existing keys on the building are Kwikset, the Weslock keyway will not accept them.
8) My building already keys everything to Kwikset. What keyed entry knob matches that keyway?
The Weslock 1740 Impressa uses a 5 pin Weslock keyway, so it keys to Weslock keys, not to another maker's. If the property is standardized on Kwikset keys, the Cal-Royal BER00 (BER00) is a Grade 3 entrance/office knob lock supplied with a Kwikset keyway, for doors 1-3/8 inch to 1-3/4 inch.
9) Which knobs look like the Weslock 1740 Impressa entry knob but will not lock a door?
Dummy trim is the usual mix-up. The Schlage A170 (SCH-A170-NONKEYED), the BEST 6K single dummy trim (BEST-6K-1DT), the Omnia 434/0 (OMN-434/0), and the Emtek Georgetown crystal knob dummy pair (EMTEK-CLASSIC-CRYSTAL-KNOBS-GEORGETOWN-DUMMY-PAIR) are all dummy-function knobs: they mount as a pull with no latch and no cylinder. The Weslock 1740 Impressa is entrance function, keyed with a single cylinder and an adjustable latch, so it actually secures the opening.
10) The door is thicker than 1-3/4 inches. Which entry knob covers it besides the Weslock 1740?
The Weslock 1740 Impressa covers 1-3/8 inch to 1-3/4 inch as standard, with an optional thickness package taking it up to 2-1/4 inch. Other keyed knobs that reach past 1-3/4 inch include the Corbin Russwin CK4851 (COR-CK4851-KEYED), a Grade 1 entrance/office lock for 1-3/8 inch to 2 inch doors, and the Deltana 6171 Round Knob entry (DEL-6171) and Deltana 3381 Egg Knob entry (DEL-3381), both rated 1-3/8 inch to 2 inch. For a non-keyed opening on a thick door, the Falcon X101 (FAL-X101) is a Grade 1 heavy duty passage knobset covering 1-3/8 inch to 2-1/4 inch.
11) Is the Weslock 1740 a single cylinder or double cylinder entry lock?
Single cylinder. Key on the outside, thumbturn or button operation inside, entrance function, so nobody needs a key to get out. That is the arrangement most residential codes expect on a dwelling exit door.
12) What strike comes with the Weslock 1740 knob lock, and will it cover my existing mortise in the jamb?
A round corner full lip strike is included. The full lip extends past the jamb face to protect the casing on the pull side, and the radiused corners match a routed jamb prep rather than a square chiseled one. If your jamb is cut square, the round corner strike will leave the corners of the old mortise showing.
13) Do I have to know my backset before ordering the Weslock 1740, the way I do with some locksets?
No, the latch adjusts between 2-3/8 and 2-3/4 inch, so one part covers both preps. Faceplates are removable too, which lets you match the existing latch face in the door edge. What you do have to specify up front is door thickness (standard 1-3/8 to 1-3/4, or the 1-3/4 to 2-1/4 option) and the keying, keyed different or keyed alike.
14) What is a Grade 3 keyed entry knob alternative to the Weslock 1740 Impressa?
The Weslock 1740 Impressa meets ANSI A156.2 Grade 2. Grade 3 keyed entry knobs in the same residential class include the Cal-Royal BER00 (BER00), entrance/office function for 1-3/8 inch to 1-3/4 inch doors; the Pamex FTF Baron (PMX-FTF-00), Grade 3 entrance/office over the same range; the Master Lock BC Series (BC01), a Grade 3 keyed entry biscuit knob; and the Callan Canova (CLN-360501) and Santo (CLN-360601) Grade 3 entrance knobsets.
15) The door does not need a key, just a latch. What is the non-keyed version to order instead of the Weslock 1740?
The 1740 Impressa is keyed with a single cylinder, so it is more lock than a hall or closet door needs. For a latching, non-locking knob, the Dexter C2000 passage knob (DEX-C2000-PASS-KNB) is a Grade 2 non-keyed passage ball knob for doors 1-3/8 inch to 1-3/4 inch, the Arrow MK01 (AR-MK01) is a Grade 2 non-keyed passage knob over the same thickness range, and the Pamex FTF passage (PMX-FTF30) is a Grade 3 Baron knob in passage function. For a bedroom or bath, the Dexter C2000 privacy knob (DEX-C2000-PRIV-KNB) is a Grade 2 push-button privacy knob rather than a keyed one.
16) I want a decorative solid brass entry knob rather than the Weslock Impressa. What are the options?
The Weslock 1740 Impressa is a brass-substrate entrance knob in the Elegance collection, offered in oil rubbed bronze and satin nickel. For a more traditional decorative look in the same keyed entry function, the Deltana 6901 Portland Knob entry (DEL-6901) fits 1-3/8 inch to 1-3/4 inch doors, and the Deltana 3381 Egg Knob (DEL-3381) and 6171 Round Knob (DEL-6171) cover 1-3/8 inch to 2 inch. Note that the Baldwin Estate 5077 Bethpage (5077.PRIV) and the Emtek porcelain and crystal knobsets are privacy or dummy trim, not keyed entry.
17) I do not want to carry keys for this door. Is there a knob that opens with a code instead of the Weslock 1740?
The Weslock 1740 Impressa opens with a key on a 5 pin Weslock cylinder. If the goal is to stop issuing keys for the opening, the Lockey 3830 (LOC-3830) is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors 1 3/16 inch to 2 inch. It is a code-entry knob rather than a keyed cylinder, so it will not join a keyed-alike system the way the Weslock will.
18) Does a fire-rated opening rule out the Weslock 1740 Impressa knob?
The 1740 Impressa is a residential entrance knob meeting ANSI A156.2 Grade 2. When the opening carries a fire label, specify a knob listed for it: the Falcon W101 (FAL-W101-KNOB) is a Grade 2 medium duty cylindrical knob in passage/closet latch function with a 2-3/4 inch backset and a fire rating, and the Falcon X101 (FAL-X101) is the Grade 1 heavy duty fire-rated passage knobset covering 1-3/8 inch to 2-1/4 inch doors.
19) What finishes does the Weslock Impressa keyed entry knob come in?
Two: oil rubbed bronze and satin nickel, both on the Impressa knob design from the Elegance collection. The rosettes are zinc diecast and the lockset substrate is brass. If you are matching hardware across a house, those are the two Impressa options, so pick the one that lines up with the hinges and the deadbolt already on the door.
20) Does the Weslock 1740 knob have exposed screws on the outside?
No. Installation screws are concealed, and the knobs come off the spindle for install so you are not dragging a finished knob against the door face while you set the rose. That also makes it easier to paint or finish around the rose without marking the knob.
