Kwikset 300CV-15 – Frequently Asked Questions

1) Will the Kwikset 300CV Cove privacy knob work with a 2-3/8 inch backset, or do I need the 2-3/4?
Either one. The 300CV ships with the 6AL adjustable latch, which sets to a 2-3/8 inch or 2-3/4 inch backset, so you don't have to know your bore-to-edge dimension before ordering. Those are the two standard residential backsets, so the latch covers effectively any prepped interior door.
2) Is the Kwikset 300CV Cove knob handed, or can I use it on a left-hand door?
It's reversible, so the same lockset goes on a left-hand or right-hand door without ordering a different part. Useful if you're buying in quantity for a building and don't want to count swings door by door.
3) Can you unlock a Kwikset 300CV privacy knob from the outside if someone is locked in the bathroom?
Yes. The privacy function locks from the inside with a turn button, and there's an emergency release on the outside knob that opens with a small tool. That's the standard bed and bath arrangement and the reason privacy locks are allowed on bathrooms where a keyed lock would not be.
4) Is the Kwikset 300CV Cove knob rated for commercial use in an office building?
No. It's ANSI/BHMA Grade 3 and catalogued for residential use, which is right for apartments, single-family, and light multi-family bedrooms and baths. For a commercial corridor or an institutional restroom you want Grade 2 or Grade 1 hardware instead, such as the Dexter C2000 Grade 2 privacy knob or, for heavy traffic, a Grade 1 cylindrical line like the Schlage D Series.
5) The room needs a key, not a privacy button. What replaces the Kwikset 300CV on an office or entry door?
The 300CV is non-keyed. For a keyed opening at a similar duty level, the Cal-Royal BER00 entrance/office knob lock is Grade 3 and uses a Kwikset keyway, which keeps the door on the same key system as other Kwikset cylinders. The Pamex FTF Baron in entrance/office function is also Grade 3 with a 1-3/8 inch to 1-3/4 inch door thickness range.
6) What is the closest equivalent to a Kwikset 300CV Cove privacy knob from another brand?
The Kwikset 300CV is a Grade 3 non-keyed privacy knobset for bed and bath doors. The closest direct equivalents are the Pamex FTF Baron knob lockset in privacy function, also Grade 3, and the Cal-Royal BER20 privacy knob lock, also Grade 3 with brass trim. Both Pamex and Cal-Royal list a 1-3/8 inch to 1-3/4 inch door thickness range, so they suit the same standard interior doors the 300CV is intended for.
7) I need a privacy knob for a commercial corridor, not a bedroom. What should I use instead of the Kwikset 300CV?
The Kwikset 300CV Cove is a residential Grade 3 privacy knob. For higher-traffic work, the Dexter C2000 Series privacy ball knob is Grade 2, non-clutching and non-keyed, with a 1-3/8 inch to 1-3/4 inch door thickness range. Dexter carries the same privacy/bed/bath function in a Grade 2 build.
8) Does the Kwikset 300CV work on a fire-rated door?
The Kwikset 300CV is a residential Grade 3 privacy knobset. Where a fire rating is required on the opening, the Falcon W101 Grade 2 cylindrical knob lock and the Falcon X101 Grade 1 cylindrical knobset are both listed as fire rated, though both are passage/closet function rather than privacy.
9) My door is thicker than 1-3/4 inches. What knob lock should I order instead of the Kwikset 300CV?
Several knob locks cover thicker doors. The Deltana 6112 St. Thomas privacy knob is listed for 1-3/8 inch to 2 inch doors, the Corbin Russwin CK4310 Grade 1 passage lock for 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset for 1-3/8 inch to 2-1/4 inch. Only the Deltana among these carries the privacy/bed/bath function.
10) What strike comes with the Kwikset 300CV, and will it match my existing door frame prep?
It comes with the RCS round corner strike, which suits frames prepped with a radius-corner mortise, common on metal frames and on doors where a router with a corner-round bit was used. If your jamb has a square-cut strike mortise, the round corner strike will leave gaps at the corners and you'd want a square corner or full lip strike instead.
11) What finishes does the Kwikset Cove 300CV privacy knob come in?
Four: Satin Nickel, Satin Chrome, Venetian Bronze, and Matte Black. If you're standardizing a building, Satin Nickel and Matte Black are the two that most often match modern trim packages, while Venetian Bronze pairs with traditional oil-rubbed looks. The Cove knob itself is a traditional style profile.
12) I need a privacy knob for a bedroom but Kwikset is residential grade. What else do you carry?
Several privacy knobs sit alongside the Cove. Pamex FTF and Cal-Royal BER20 are both Grade 3 privacy knobs rated for 1-3/8 to 1-3/4 inch doors. The Dexter C2000 privacy ball knob steps up to Grade 2 for heavier traffic. On the decorative side, Deltana 6112 St. Thomas and the Baldwin Estate 5077 Bethpage are solid-brass privacy knobs for higher-end residential work.
13) Do I need a privacy knob or a passage knob for a closet door?
Passage. A closet or hall door doesn't need to lock, so a passage latch is the right call and cheaper to buy. The Kwikset 300CV is a privacy function, meant for bedrooms and bathrooms where someone needs to lock the door from inside. For the closets on the same job, Pamex FTF passage or the Dexter C2000 passage ball knob cover it.
14) The door does not need a lock, just a latch. What matches the Kwikset 300CV knob style without the privacy button?
The Kwikset 300CV is a privacy function with an inside turn button. For a closet or hall door that only needs a latch, passage knobsets include the Pamex FTF Baron in passage function, Grade 3; the Bravura Albany round-trim passage knobset, Grade 2; and the Arrow MK01 passage cylindrical knob lock, Grade 2 with a 1-3/8 inch to 1-3/4 inch door thickness range. All are non-keyed with no locking function.
15) Will a dummy knob work in place of the Kwikset 300CV?
No. The Kwikset 300CV is a working privacy lockset with a 6AL adjustable latch and RCS round corner strike. Dummy trims such as the Schlage A170 single dummy, the BEST 6K Series single dummy trim, or the Bravura Biloxi dummy knobset have no latch and no locking function at all - they are surface-mounted pulls for inactive doors. They will not secure a bathroom or bedroom.
16) I want a decorative privacy knob instead of the Kwikset 300CV Cove. What are the options?
The 300CV Cove is a traditional-style knob offered in Venetian Bronze, Satin Nickel, Satin Chrome and Matte Black. For a more ornamental look in the same privacy function, the Baldwin Estate 5077 Bethpage privacy knob with R027 rose and the Deltana 6112 St. Thomas privacy knob are both privacy/bed/bath knobs, with the Deltana covering a 1-3/8 inch to 2 inch door thickness range.
17) I am outfitting a whole unit and need matching knobs on the entry and interior doors. How does the Kwikset 300CV pair with that?
The Kwikset 300CV covers the bed and bath doors only, since it is a non-keyed privacy function. If you would rather buy one package covering both, the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes, listed for 1-3/8 inch to 1-3/4 inch doors. The Sure-Loc Bergen round knob also comes as a 6-pack with adjustable backset for multi-door work.
18) What is the difference between the Kwikset 300CV and a Grade 1 knob lock like the Sargent 8XG04?
The Kwikset 300CV is a Grade 3 residential privacy knobset, reversible for left- and right-hand doors. The Sargent 8XG04 is a Grade 1 heavy duty storeroom function knob lock with a single cylinder and a 2-3/4 inch backset, which means it is keyed and always locked from outside rather than privacy-latched from inside. They serve different openings: the 300CV a bedroom or bathroom, the 8XG04 a secured storage or utility room.
19) What is the Microban feature on the Kwikset Cove knob?
The 300CV is listed with Microban, an antimicrobial treatment built into the finish that inhibits bacterial growth on the knob surface. It's a reason this one gets specified for bathrooms and healthcare-adjacent residential settings over an untreated knob.
20) What tools do I need to install the Kwikset 300CV, and does it include the latch and strike?
A screwdriver is all it takes on a door that's already bored. The set includes the 6AL adjustable latch and the RCS round corner strike, so nothing separate is required to finish a standard interior door beyond the strike screws that come with it.
