Baldwin TK009 Turn Knob

The TK009 is a thumbturn-style turn knob, not a lockset. It is the inside turn piece that operates a mortise lock, a tubular bolt, or sectional trim. It is non-keyed, so there is no cylinder and no key on this piece. If you need a full knob lock with a latch and strike, this is not it. It can also be paired with Baldwin ER trim to build a custom turn piece.

No. The TK009 is only the turn piece, it has no latch, no strike and no outside knob. For a privacy bed and bath function with everything in the box, look at a privacy knobset such as the Deltana 6112 St. Thomas, which fits 1-3/8 to 2 inch doors, or the Dexter C2000 Grade 2 privacy knob for 1-3/8 to 1-3/4 inch doors.

Yes. It is made for interior and exterior mortise locks as well as tubular deadbolts, so on an entry door it serves as the inside thumbturn that throws the bolt. The keyed cylinder and exterior trim are separate parts, since the TK009 itself is non-keyed.

Yes. The TK009 is a turn piece only, non-keyed, intended to drive an interior or exterior mortise lock, a tubular bolt, or sectional trim - it is not a complete lockset and will not latch a door on its own. If the door is bored for a standard cylindrical lock and you need a self-contained privacy function, the Dexter C2000 privacy ball knob lock is a Grade 2 non-keyed privacy set for doors 1-3/8 inch to 1-3/4 inch, and the Pamex FTF Baron is a Grade 3 privacy knob lockset for the same 1-3/8 inch to 1-3/4 inch range. Both include the latch; the TK009 does not.

No, and they are not interchangeable. A dummy knob is fixed trim that does not rotate or operate anything - the Schlage A170 single dummy trim and the BEST 6K single dummy trim are both Grade 2 dummy-function knobs, and the Omnia 434/0 and Emtek Hammered Egg dummy pair are the same idea in decorative brass. The TK009 rotates: it is a turn piece that throws a mortise lock or a tubular bolt from the inside. If you want a non-operating pull on a closet or false door, a dummy is correct; if you need to throw a bolt, only the turn knob does that.

The TK009 is a residential turn piece and carries no ANSI grade. For commercial and institutional openings that require a graded cylindrical knob lock, the Sargent 8XG04 is a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset and single cylinder, the BEST 8K is a Grade 1 heavy duty entrance knob lock, and the Schlage D10S is a Grade 1 heavy duty passage latch with an Orbit knob. Step down to Grade 2 with the Sargent 6G04 storeroom or the Falcon W101 passage knob, which is fire rated.

Projection is 0.8 inch off the face of the door. That is worth checking against anything mounted close to the opening, a door that swings tight to a return wall, or where a thick casing or an adjacent cabinet could catch the knob.

It's catalogued as residential hardware. For a commercial opening or a high traffic multi-family corridor where a graded lock is required, look at Grade 1 or Grade 2 cylindrical knob locks instead, such as the Schlage D10S passage or the Corbin Russwin CK4310, which is Grade 1 and covers 1-3/8 to 2 inch doors. Those are complete locksets, not turn pieces.

Fourteen finishes: 003 Polished Brass, 031 Non-Lacquered Brass, 033 Vintage Brass, 044 Satin Brass, 050 Satin Brass and Black, 055 Polished Nickel, 056 Satin Nickel, 060 Satin Brass and Brown, 076 Graphite Nickel, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 190 Satin Black, 260 Polished Chrome, and 402 Distressed Oil Rubbed Bronze. Order by the Baldwin finish number and it will match the same number on your other Baldwin trim.

The Baldwin TK009 is non-keyed and provides only inside turn operation, so it is paired with a lock rather than used as the keyed side. For a keyed entry knob, the Kwikset 400P-CP Polo is a Grade 3 entry knob for 1-3/8 inch to 1-3/4 inch doors with a round corner adjustable latch and strike, the Cal-Royal BER00 is a Grade 3 entrance/office knob with a Kwikset keyway on the same thickness range, and the Corbin Russwin CK4851 is an entrance/office cylindrical lock with a conventional cylinder for 1-3/8 inch to 2 inch doors. In brass trim, the Deltana 6171 Round Knob and 3381 Egg Knob are entry function for 1-3/8 inch to 2 inch doors.

No. The TK009 is a turn piece with a 0.8 inch projection that drives a mortise lock, tubular bolt or sectional trim on a residential opening. Exit device trim is a different part that mounts to a panic device: the Sargent 28C-KNOB is knob and rose trim for 1-3/4 inch doors, the Sargent 78-2875 is an outside knob only in the 7800 Series, and the Imperial USA ED-BKL580 is storeroom-function knob trim for the ED-500 Series. Match exit trim to the device family, not to a residential turn knob.

Lifetime Satin Nickel (056) is nickel plating over solid brass, applied as a PVD finish, so you get the brass weight with a matte silver tone. It's a hard-wearing finish rather than a lacquer that can wear through at the turn.
