Baldwin K012190IMR – Frequently Asked Questions

1) Will the Baldwin K012 knob work on a 1-3/8 inch interior door?
Yes. The K012 knob with 5078 rose covers doors from 1-3/8 inches up to 1-3/4 inches thick, so both the common older interior thickness and standard 1-3/4 inch doors are within range. Anything thinner than 1-3/8 or thicker than 1-3/4 is outside what this trim is built for.
2) What is the difference between ordering the K012 knob as a Half Pair versus a Pair?
A Pair gives you knob trim for both faces of the door, which is what you need for a passage or privacy opening or a full dummy. Half Pair is a single knob and rose for one face only, used for a half dummy on a closet or pantry door, or to replace one damaged side of an existing set. There is also a Pair (PINNED) option, where the knob is pinned to the spindle rather than left free.
3) Is this Baldwin knob a complete lockset, or do I need to order more parts?
The K012 with 5078 rose is trim only, the knob and rose. It is not a lock. You add it to the lock body you want: it works on tubular and mortise lock types, so you pair it with a tubular passage or privacy mechanism, or use it as trim on a mortise lock set. Mortise applications can also use handleset trim or an escutcheon plate instead of the round rose.
4) Is the Baldwin K012 knob suitable for a commercial corridor or apartment entry?
It is classified as residential trim, so for a commercial corridor or a code-driven opening in a public building it is the wrong choice. Use it in single-family homes, condo interiors, and multi-family unit interiors where the design matters and traffic is light. For high-traffic or accessibility-driven openings, a lever is the usual answer since a round knob is harder to operate with a closed fist.
5) How far does the Baldwin K012 knob stick out from the door, and how big is the knob?
Projection is 2.375 inches off the door face, and the knob measures 2.44 inches in diameter. Those two numbers matter when the door swings into a tight corner, sits close to a wall or casing, or when a hand rail, cabinet, or adjacent door leaf could contact the knob at full swing.
6) Can I mix this K012 knob with Baldwin levers on the same door or in the same house?
Yes, that is how the Estate Series trim is set up. Knobs and levers are sold individually or in pairs so you can run a lever on the hall side and a knob inside, or keep levers on main passage doors and knobs on closets, and hold one finish across the whole job. Order Half Pair when you only need one face.
7) What finishes can I get the Baldwin K012 knob in to match hardware already in the building?
Fourteen finishes, covering the usual match targets: Polished Brass (003), Non-Lacquered Brass (031), Vintage Brass (033), Satin Brass (044), Satin Brass and Black (050), Polished Nickel (055), Satin Nickel (056), Satin Brass and Brown (060), Graphite Nickel (076), Oil Rubbed Bronze (102), Venetian Bronze (112/11P), Satin Black (190), Polished Chrome (260), and Distressed Oil Rubbed Bronze (402). Order by the number rather than the name, since several brass tones read similarly in photos.
8) Can I use the K012 knob as a dummy handle on a closet or French door?
Yes. The trim is offered in a Full Dummy or Half Dummy configuration: Half Pair for a single non-operating knob on one face, Pair for dummy trim on both faces of an inactive leaf. Dummy trim has no latch, so it is a pull only.
9) Does the Baldwin K012 knob need to be ordered left or right handed?
No handing to specify on the K012. It is a round knob, symmetrical in every direction, so the same part works on a left hand or right hand door. The only choices you make are finish, and whether you need a Pair, a Half Pair, or a Pair (PINNED).
