Baldwin BAL-K012.033.PASS – Frequently Asked Questions
1) Does the Baldwin Estate K012 passage knob lock, or is it just a latching knob?
The K012 is a passage function knob, so it latches the door closed but has no lock and no key. Use it on halls, closets, and any interior opening that only needs to stay shut. For a bathroom or bedroom you want the privacy version of the same knob instead, which adds the push-button turn.
2) What door thickness does the Baldwin K012 knob fit?
It covers 1.37 inch through 1.75 inch doors, which takes in both the common 1-3/8 inch interior door and the 1-3/4 inch thickness. No extension kit is needed inside that range; a thicker door than 1-3/4 inch falls outside what this set is built for.
3) Is the Baldwin Estate K012 knob rated for commercial use in an office or apartment corridor?
Baldwin classifies the Estate K012 as residential hardware. It suits homes, model units, and high-end interiors. For a commercial corridor or any opening carrying real traffic and code requirements, specify a commercial-grade cylindrical lockset rather than this one.
4) Can I mix the K012 knob with a lever or a different rose on the other side of the door?
Yes. Baldwin Estate knobs and levers are sold as a pair or individually, so you can run the K012 tulip knob on one face and a lever on the other, or swap the rose. The same mix-and-match applies across passage and privacy interior sets and to mortise trim using handle set trim or escutcheon plates.
5) What finishes does the Baldwin K012 passage knob come in for matching the rest of a house?
Eleven finishes: 003 Polished Brass, 031 Non-Lacquered Brass, 033 Vintage Brass, 044 Satin Brass, 055 Polished Nickel, 056 Satin Nickel, 076 Graphite Nickel, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 190 Satin Black, and 260 Polished Chrome. Note that 031 non-lacquered brass is a living finish and will patina over time, while the lacquered 003 holds its shine.
6) Will the Baldwin K012 with 5078 rose match the other Estate knobs already on my doors?
If the existing doors carry Baldwin Estate trim, the K012 tulip knob on the round 5078 rose will suite with them by design and finish code, since Estate roses and handles are meant to be combined across a set. Match on the finish number, not the finish name, to keep the run consistent.
7) Is the K012 a bored cylindrical set or a mortise lock?
It is bored cylindrical trim, so it installs in a standard bored door prep rather than a mortise pocket. Baldwin Estate knobs of this style can also be applied to mortise lock sets using handle set trim or escutcheon plates, but the K012 passage set as configured here is the cylindrical version.
8) What style is the Baldwin K012 tulip knob, traditional or contemporary?
Transitional. The tulip shape reads traditional in silhouette but the clean rose and finish range let it sit in a modern interior, which is why it gets specified in remodels where old and new millwork meet.
