Deltana 6112 St. Thomas Knob Privacy

It is a non-keyed privacy set for bed and bath doors. You get a thumbturn or push button inside and an emergency release on the outside, with no cylinder and no keys. If you need a key on the outside for an exterior or office door, this is the wrong function, look at a keyed entry set like the Cal-Royal BER00 entrance/office knob instead.

In most cases yes. It is a tubular bored lockset with an adjustable 2-3/8 or 2-3/4 inch backset, which covers the two standard preps found on residential doors, and it handles 1-3/8 through 2 inch thickness. If the old knob was a standard bored set on a 2-1/8 inch cross bore, no new drilling is needed.

The Deltana 6112 St. Thomas is a non-keyed tubular privacy/bed/bath knobset with an adjustable 2-3/8 or 2-3/4 backset for doors 1-3/8 inch to 2 inch thick. For the same function in another brand, the Pamex FTF Baron knob lockset is a Grade 3 privacy knob for doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal BER20 is a Grade 3 privacy knob with brass trim for the same thickness range, and the Baldwin Estate 5000 Baltimore knob with 5148 rose is a privacy lock supplied with a 2-3/8 inch backset and full lip strike. All lock the same way: no key, turn or button release from inside.

The Deltana 6112 St. Thomas is designated residential and built from steel and zinc, so for commercial traffic look at graded cylindrical hardware. The Dexter C2000 Series privacy ball knob is Grade 2, non-clutching and non-keyed, for doors 1-3/8 inch to 1-3/4 inch. If you want heavy duty, Schlage D Series D10S is a Grade 1 heavy duty cylindrical knob lock, though it is a passage latch rather than privacy, and Sargent 8XG04 is Grade 1 heavy duty in a storeroom function with a 2-3/4 inch backset.

No. The Deltana 6112 St. Thomas is a working privacy/bed/bath lockset with a latch and a tubular lock body. A dummy knob is fixed trim with no latch and no lock at all, used on inactive or closet-pair doors. Items such as the BEST 6K Series single dummy trim, Schlage A170 single dummy trim, Cal-Royal BA40 dummy knob and the Omnia 434/0 egg-shaped single dummy are dummy trim, so none of them will secure a bathroom door.

The Deltana 6112 St. Thomas covers 1-3/8 inch to 2 inch doors, so it does fit a 2 inch door. Among other knob locks with that reach, the Corbin Russwin CK4310 passage cylindrical lock is rated 1-3/8 inch to 2 inch, the Corbin Russwin CK4851 entrance/office lock is also 1-3/8 inch to 2 inch, and the Falcon X101 passage knobset goes to 2-1/4 inch. Many competing knob locks, including the Dexter C2000 and Pamex FTF sets, stop at 1-3/4 inch.

The Deltana 6112 St. Thomas is a residential privacy knobset. For a rated opening, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock carrying a fire rating with a 2-3/4 inch backset in passage/closet latch function, and the Falcon X101 is a Grade 1 heavy duty passage knobset with a fire rating and an interchangeable core for doors 1-3/8 inch to 2-1/4 inch. Both are latch functions rather than privacy, so confirm the function your door schedule calls for.

The Deltana 6112 St. Thomas is a residential tubular privacy knobset. If your spec calls for a stated ANSI/BHMA grade on a privacy knob, the Dexter C2000 Series privacy ball knob is Grade 2, and the Pamex FTF Baron privacy and Cal-Royal BER20 privacy knobs are both Grade 3. Institutional buyers writing a grade into the submittal should order against one of those.

Handing is not a factor. The 6112 is universal, so one part number works on a left or right hand door swinging either direction. Just flip the latch tongue to face the stop if your latch ships the wrong way.

The 6112 St. Thomas works for that if the doors are residential and fall in the 1-3/8 to 2 inch thickness range, since the adjustable backset means you do not have to sort doors by prep before ordering. Pick one of the three finishes and order the same finish across the run. If some of those doors also need passage or dummy trim in a matching look, you would be mixing Deltana functions rather than relying on this single model.

The 6112 St. Thomas is a privacy function, so it is not the right pick where no locking is wanted. For a latching knob with no lock, the Pamex FTF Baron in passage function is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, the Dexter C2000 passage ball knob is Grade 2 and non-keyed, and the Kwikset 200P-CP Polo passage knob comes with a round corner adjustable latch and round corner strike. Bravura Albany and Lynchburg are Grade 2 passage knobsets with round trim if you want a decorative rose closer to the St. Thomas look.

The Deltana 6112 St. Thomas is a privacy knob offered in Polished Brass and Antique Brass among its finishes. In a more ornamental vein, the Baldwin Estate 5077 Bethpage privacy knob uses the R027 rose and is the same privacy/bed/bath function, and the Baldwin Estate 5000 Baltimore 2 inch knob with 5148 rose is a privacy lock preconfigured with a 2-3/8 inch backset and full lip strike. Both are Baldwin Estate line knobs rather than tubular residential sets.

The 6112 St. Thomas is non-keyed, so it will not accept a cylinder. For a keyed knob, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for the same thickness range, and the Pamex FTF Baron in entrance/office is Grade 3. On the commercial side, Corbin Russwin CK4851 is an entrance/office cylindrical knob lock with a conventional cylinder for doors up to 2 inch.

The 6112 St. Thomas privacy knob is offered in Brushed Chrome, Polished Brass and Antique Brass, so the simplest way to keep an apartment consistent is to hold the finish across functions. If you need a multi-pack for a whole unit, the Sure-Loc Bergen round knob ships as a 6-pack with adjustable backset, and the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 inch to 1-3/4 inch doors. Those are different knob designs, so use them where matching the St. Thomas rose is not required.

Not as a functional swap. The Deltana 6112 St. Thomas is a tubular privacy lockset with an adjustable 2-3/8 or 2-3/4 backset. The Emtek porcelain knobs ship as two knobs per set with a threaded rod, and the Emtek Classic Brass Crystal Georgetown and Providence knobs are dummy pairs, as is the Arts and Crafts Hammered Egg knobset in dummy. Those are trim products that need a separate lock body or serve non-latching doors, so they will not give a bathroom door a privacy lock on their own.

Three: brushed chrome, polished brass, and antique brass. Brushed chrome pairs with satin nickel and chrome trim already in a room, while the two brass tones suit traditional interiors. All three are the same knob and latch underneath, so mixing finishes across doors in one house is purely cosmetic.

Steel and zinc. That is typical construction for a residential tubular knobset and it keeps the knob light on the spindle. Buyers looking for solid brass through the knob and rose would be looking at something like the Omnia 434 series instead.
