Deltana 6172 Round Knob Privacy

Either one. The 6172 privacy knobset ships with an adjustable latch that sets to a 2-3/8 or 2-3/4 inch backset, so you measure from the door edge to the center of the bore and set it on site. That covers both of the backsets used on standard residential bored doors.

Yes. The 6172 is rated for doors from 1-3/8 inch up to 2 inch thick, so older 1-3/8 inch interior doors and standard 1-3/4 inch doors are both covered, along with thicker slabs up to 2 inches.

No key. The 6172 is a privacy function knobset, non-keyed, the type used on bedrooms and bathrooms. It locks from the inside knob and releases with an emergency tool from the outside. If you need a knob that locks with a key, look at a keyed entry function instead, such as the Cal-Royal BER00 entrance/office knob lock.

It is built as a residential knobset in steel and zinc, and no ANSI grade is carried on it, so it suits homes and light interior use. For rental turns and commercial openings where a graded lockset is specified, a Grade 2 privacy knob like the Dexter C2000 privacy ball knob or the Cal-Royal BER20 Grade 3 privacy knob is the closer match.

The Deltana 6172 is a non-keyed tubular privacy/bed/bath knob with an adjustable 2-3/8 or 2-3/4 backset. The closest same-function alternatives are the Pamex FTF Baron knob lockset in privacy function, a Grade 3 set for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal BER20 privacy knob lock, also Grade 3 for 1-3/8 to 1-3/4 inch doors with brass trim. Both do the same bed and bath job; the Deltana carries a wider 1-3/8 to 2 inch door thickness range.

The Deltana 6172 is a residential-duty tubular privacy knob. For a higher-traffic opening, the Dexter C2000 Series privacy cylindrical ball knob lock is a Grade 2 non-keyed privacy set for 1-3/8 to 1-3/4 inch doors. If the same door family also needs passage and entry sets, the Dexter C2000 line covers passage, entry/office and classroom functions at the same Grade 2 level for standardizing a floor.

No. The Deltana 6172 is non-keyed with a privacy/bed/bath function, so it has no cylinder and cannot be keyed. For a keyed opening, look at the Cal-Royal BER00 entrance/office Grade 3 knob lock with a Kwikset keyway, the Kwikset 400P Polo keyed entry knob with 6AL latch and RCS strike, or the Callan Edgewood Grade 2 entrance knobset.

Dummy trim knobs look nearly identical on the door but have no latch and no locking action - they are surface-mounted pulls for inactive or closet doors. Examples are the BEST 6K Series single dummy trim, the Schlage A170 single dummy trim, the Bravura Biloxi round trim dummy knobset, and the Omnia 458/0 single dummy knob latchset. The Deltana 6172 is a working tubular privacy lockset, so only privacy-function sets substitute for it on a bath or bedroom door.

No handing to specify. The 6172 round knob is universal hand, so one part works on a left or right swing door. Set the latch for your backset and go.

It's a tubular bored lockset with an adjustable 2-3/8 or 2-3/4 backset and a 1-3/8 to 2 inch thickness range, so it goes into a standard bored door prep without new holes on most interior doors. Check that your existing cross bore matches a standard tubular prep before pulling the old knob.

The 6172 is the privacy version of Deltana's Round Knob series, so it pairs visually with the passage and dummy versions of the same knob. Use privacy on bedrooms and baths, passage on halls and closets. If you want a single-brand bulk option for a whole floor of passage doors, the Sure-Loc Bergen round knob comes in a 6-pack with an adjustable backset.

Both are privacy function for bed and bath doors. The 6172 is a steel and zinc residential knobset offered in six finishes with an adjustable 2-3/8 or 2-3/4 backset. The Baldwin Estate 5000 Baltimore privacy knob with 5148 rose is a preconfigured set at a fixed 2-3/8 inch backset with a full lip strike, and the Estate 5077 Bethpage is another privacy option in that line.

The Deltana 6172 is privacy function, so it has a bed and bath push or turn lock. For a hall or closet door that only needs to latch, the Pamex FTF Baron knob lockset in passage function is the direct Grade 3 counterpart for 1-3/8 to 1-3/4 inch doors. Other passage knobs include the Kwikset 200P Polo passage knob supplied with a 6AL latch and round corner strike, and the Bravura Albany round trim passage knobset, Grade 2.

The Deltana 6172 fits doors 1-3/8 to 2 inch thick. Among knob locks with a comparable range, the Corbin Russwin CK4310 Grade 1 passage cylindrical lock covers 1-3/8 to 2 inch, the Corbin Russwin CK4851 entrance/office cylindrical lock covers 1-3/8 to 2 inch, and the Falcon X101 Grade 1 passage knobset covers 1-3/8 to 2-1/4 inch. Those three are passage and entrance functions rather than privacy.

The Deltana 6172 is sold as a privacy/bed/bath knobset in six finishes including PVD Polished Brass, Oil Rubbed Bronze, Antique Nickel, Polished Chrome, Brushed Chrome and Antique Brass, so you would pair it with matching Deltana functions. If you prefer a single packaged combo, the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 to 1-3/4 inch doors, and the Sure-Loc Bergen round knob ships as a 6-pack with adjustable backset.

Six: PVD Polished Brass, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, Antique Nickel, and Antique Brass. If you're matching existing hardware through a house or a unit, the PVD polished brass is the one that holds its shine longest of the brass tones.
