Schaub 251-VN – Frequently Asked Questions

1) Will the Schaub 251 knob cover the old holes if I am replacing existing cabinet knobs?
Cabinet knobs mount on a single hole, so a straight knob-for-knob swap reuses the existing bore. The 3/4 inch base is what sits against the door, so it will hide a standard single knob bore but not the two-hole pattern left by a pull. Coming off pulls means either filling and re-drilling, or moving to a pull with matching centers.
2) What is the closest alternative to the Schaub 251 Siena knob if I want solid brass instead of zinc?
The Schaub 251 Siena square cabinet knob has a zinc base material. If the specification calls for solid brass, Delaney offers a solid brass cabinet knob in its Cabinet Knobs series, and Deltana's KRB175 is a heavy-duty solid brass round knob at 1-3/4 inch diameter. Both are round profiles rather than the square Siena face, so the visual will change where knobs sit side by side on a run of cabinets.
3) I need a larger knob face than the Schaub 251 for oversized drawer fronts. What else works?
The Schaub 251 has a 1-3/8 inch knob diameter. For a larger grip on wide drawer fronts, the Deltana KRB175 round knob measures 1-3/4 inch in diameter and is built heavy-duty in solid brass. It is a round knob with a groove detail rather than a square rustic face, so it reads differently on a shaker or slab door.
4) How far does the Schaub 251 Siena knob stick out from the cabinet door?
Projection is 1 inch, so the knob stands an inch off the face. The base that sits against the door measures 3/4 inch and the knob itself is 1-3/8 inch diameter. That inch of projection matters where doors sit next to an appliance panel, a wall return, or an adjacent door that swings past, and it is enough to get a full hand grip rather than fingertips.
5) What finishes does the Schaub 251 Siena square knob come in?
Two finishes: Ancient Bronze (ABZ) and Vibra Nickel (VN). Ancient Bronze is the dark rustic option and Vibra Nickel the brushed silver-tone one. If you are matching an existing run of Siena hardware across a unit or a whole property, order from the same finish code, and order the full opening count in one go so the plating batch matches.
6) The Siena square knob is too rustic for a traditional or period cabinet job. What should I specify instead?
The Schaub 251 is a rustic-style square knob. For a different design language on the same cabinet doors, Emtek's Schaub-collection knobs give you the Allerton series, the Art Deco series, and the Astoria glass series, each a cabinet knob/pull. The Astoria uses a glass body rather than a metal one, which changes both the look and the cleaning routine in a high-traffic multi-family or hospitality unit.
7) What is a straightforward round cabinet knob to use in place of the Schaub 251 square?
Orca Hardware offers two round-profile cabinet knobs: the CK-18032 Mission round knob from the 18-Mission collection and the CK-19032 Whistler knob from the 19-Whistler collection. Both are cabinet knobs like the Schaub 251, so they serve the same function on a door or drawer front, with a round rather than square face.
8) The Schaub 251 comes in Ancient Bronze and Vibra Nickel. What if I need a brass finish family instead?
The Schaub 251 Siena square knob is finished in Ancient Bronze (ABZ) and Vibra Nickel (VN). Where a brass appearance is required, the Delaney solid brass cabinet knob and the Deltana KRB175 solid brass round knob are brass-bodied instead of the 251's zinc base, which changes how the finish wears and patinas over a long service life.
9) Can the Schaub 251 be used on drawers as well as cabinet doors?
Yes, it is a cabinet knob and mounts the same way on either, single 8/32 screw through a single bore. On wide drawers many designers run two knobs or switch to a pull for balance, but nothing about the 251 restricts it to doors.
10) Can I mix the Schaub 251 with Emtek Schaub-collection knobs and keep one screw size for the crew?
The Schaub 251 uses an 8/32 by 1 inch thread and screw size, the standard cabinet knob thread. Emtek's Schaub-collection pieces such as the 8665 SELECT, Allerton, Art Deco, and Astoria glass knobs are cabinet knob/pull items in the same family of cabinet hardware, so they are ordered against the same kind of drilled cabinet front. Confirm the screw length supplied with each Emtek piece against your door thickness before the crew starts the run.
