Schaub 250-ABZ – Frequently Asked Questions

1) How big is the Schaub Siena 250 knob and how far does it stick out from the cabinet face?
Knob diameter is 1-1/2 inches with a 1 inch projection off the face, and the base that sits against the wood measures 3/4 inch. The 1 inch projection is what decides finger clearance, so it grips well with a full hand, which matters on heavy pantry or base cabinet drawers. The 3/4 inch base also covers a small amount of wear or finish shadow around an existing bore.
2) Can I swap the Schaub 250 Siena knob straight into the holes my old knobs came out of?
In most cases yes, because the Siena 250 mounts on a single 8-32 machine screw, which is the standard cabinet knob thread, so an existing single knob bore takes it directly. Two things to check on your own doors: the bore must be a single hole (a knob will not cover two pull holes at a center spacing), and the 3/4 inch base has to cover any finish ring left by the old knob. If the previous hardware was a two-hole pull, you are looking at a pull, not this knob.
3) What is the closest round cabinet knob to the Schaub 250 Siena if a different brand is needed?
The Orca Hardware CK-18032 Mission Round Cabinet Knob is the nearest round-profile alternative. Both are cabinet knobs with a round face, and the Schaub 250 carries a 1-1/2 inch knob diameter with a 3/4 inch base and 1 inch projection, threaded 8/32 by 1 inch. The Orca CK-18032 comes from the 18-Mission Collection, so the styling reads Mission rather than the rustic Siena look. Verify the Orca screw length against the door or drawer front thickness before mixing the two on the same run of cabinets.
4) For a heavy-traffic commercial cabinet run, is there a larger or heavier-duty round knob than the Schaub 250?
The Deltana KRB175 is a heavy-duty round knob with a groove, 1-3/4 inch diameter, in solid brass. That is a larger face than the Schaub 250's 1-1/2 inch diameter, and solid brass rather than the Schaub's zinc base. For a hospitality or multi-family cabinet package where grip size and material matter more than matching the rustic Siena styling, the KRB175 is the substitution to price. Note the larger diameter changes spacing on narrow stiles and drawer faces.
5) What finishes does the Schaub 250 Siena knob come in?
Two finishes: Ancient Bronze (ABZ) and Vibra Nickel (VN). Ancient Bronze is the darker, warm option that suits the rustic styling of the Siena line, while Vibra Nickel gives a brushed cool-toned look for pairing with stainless appliances. If you are standardizing a whole kitchen or a run of units, pick one and order the full count in it, since finish lots are best kept together.
6) Is the Schaub 250 Siena knob solid brass or cast metal?
Zinc is the base material on the Siena 250, finished in either Ancient Bronze or Vibra Nickel. Cast zinc holds crisp rustic detail and takes plated and antiqued finishes well. If a spec on your job calls specifically for solid brass, the Deltana KRB175 round knob with groove is solid brass and 1-3/4 inches in diameter, and Delaney also lists a solid brass cabinet knob.
7) I need a rustic-look cabinet knob for a whole apartment turnover. Is the Schaub Siena a good fit?
The Siena 250 is styled rustic and comes in a single round profile at 1-1/2 inches, so every unit matches with no handing, no orientation and no left/right to sort on install. One 8-32 screw per knob, one bore per door. For unit counts, decide the finish first, Ancient Bronze or Vibra Nickel, because that is the only choice on the part.
8) Should I use a cabinet knob or a pull on my drawers?
A knob like the Siena 250 needs one bore and no center-to-center measurement, which makes it the faster install and the easier retrofit into existing single holes. A pull needs two bores at a fixed center spacing and is the better grip on wide, heavy drawers where a single point of pull racks the box. Common practice is knobs on doors and small drawers, pulls on anything wide. The Emtek SELECT 8665 in the Schaub collection is catalogued as a knob/pull if you want the two to come from one design family.
9) What other round cabinet knobs could I look at besides the Schaub Siena 250?
Staying round and similar in feel, Orca Hardware CK-18032 is a Mission round cabinet knob and CK-19032 is the Whistler, both straightforward round knobs from the same category. Deltana KRB175 is a heavier round knob with a groove detail at 1-3/4 inches diameter in solid brass, so it reads larger on the door face than the Siena's 1-1/2 inches. For a different look entirely, Emtek's Art Deco and Astoria Glass knobs in the Schaub collection move away from the rustic profile.
10) What cabinet knob should be used instead of the Schaub 250 Siena when the cabinetry is not rustic?
For a period or decorative opening rather than a rustic one, the Emtek Art Deco Cabinet Knob and the Emtek Astoria Glass Cabinet Knob are the alternatives in the same knob role. The Art Deco knob runs the Art Deco series and the Astoria is a glass knob, both catalogued as cabinet knob/pull, so each can be carried through to matching pulls. The Schaub 250 is the rustic-styled round option at 1-1/2 inch diameter. Match the knob to the door style first; the mounting is a cabinet screw either way.
11) Is the Siena 250 part of a matching collection if I want drawer pulls to go with it?
Siena is the collection name on the 250 knob, and it is a rustic-styled family, so matching pieces come from that same Siena line rather than being mixed in from another series. Schaub designs also carry through the Emtek SELECT program, which lists knob and pull items under the Schaub collection if you want a broader mix of shapes in a coordinated look.
12) Which cabinet knob is comparable to the Schaub 250 Siena for a transitional cabinet package?
The Orca Hardware CK-19032 Whistler Cabinet Knob and the Emtek Allerton Cabinet Knob both serve the same cabinet knob role. The Whistler comes from the 19-Whistler Collection and the Allerton runs the Allerton series as a cabinet knob/pull. The Schaub 250 is the round rustic option, 1-1/2 inch across the knob with a 1 inch projection off the face. Where a project standardizes on one collection across knobs and pulls, the Allerton covers both formats; where a single round knob is what the drawing calls for, the Schaub 250 or the Whistler fills it.
