Schaub 20015-GM – Frequently Asked Questions

1) Is the Schaub Quadrato knob solid brass or plated zinc?
Zinc. The 20015 uses a zinc base material with the finish applied over it, not solid brass. For a multi-family or hospitality spec where you want solid brass under the finish, the Delaney Solid Brass Cabinet Knob or the Deltana KRB175, a 1-3/4 inch solid brass round knob with a groove, are the brass options. Zinc holds up fine for normal kitchen and vanity duty; the difference shows up in weight in the hand and in how the finish wears at high-touch drawers.
2) I'm replacing knobs across a whole kitchen. Will the Quadrato cover the old screw holes?
A knob is single-hole, so as long as what you are pulling off is also a knob and not a two-hole pull, the existing hole is reused and nothing needs patching. The 1-3/8 inch square base gives you a bit of coverage around a worn or slightly oversized hole. Coming off a pull with two holes on centers, you will be filling and re-drilling, or moving to a Quadrato pull instead of the knob.
3) What is a round alternative to the Schaub 20015 Quadrato knob if the square profile is too contemporary for the cabinetry?
The Schaub 20015 Quadrato is a square knob measuring 1-3/8" x 1-3/8" overall in a contemporary style. For a round face instead, the Orca Hardware CK-18032 Mission Round Cabinet Knob is a round cabinet knob, and the Deltana KRB175 is a round knob with a groove detail in a 1-3/4" diameter solid brass build. Both serve the same cabinet knob function on doors and drawers; the difference is the face geometry and, on the Deltana, the larger grip and brass body.
4) I need a solid brass cabinet knob rather than zinc - what should I order instead of the Schaub 20015?
The Schaub 20015 Quadrato uses a zinc base material. If the specification calls for solid brass, the Delaney Solid Brass Cabinet Knob and the Deltana KRB175, a heavy-duty 1-3/4" diameter solid brass round knob, are both solid brass cabinet knobs. Note that both are round rather than the square 1-3/8" x 1-3/8" Quadrato profile, so the look on the door face will change.
5) How big is the Schaub Quadrato square knob and how far does it stick out from the door?
It is a square 1-3/8 by 1-3/8 inch face with a 1-3/8 inch knob diameter, and it projects 7/8 inch off the mounting surface. The base measures 3/8 inch. That projection is worth checking on a drawer beside an appliance or in a tight galley run, since 7/8 inch is what your knuckles clear by.
6) What finishes does the Schaub 20015 Quadrato knob come in?
Four finishes: Gun Metal (GM), Matte Black (MB), Satin Bronze (SBZ), and Signature Satin Brass (SSB). If you are matching pulls on the same run, order the Quadrato pulls in the identical finish code rather than eyeballing it, since Satin Bronze and Gun Metal read close under warm kitchen light.
7) What is a good alternative if the square Quadrato profile is too modern for my cabinetry?
Square is the whole point of the Quadrato, so if the room is traditional or craftsman, go round. The Orca Hardware CK-18032 Mission round knob and the CK-19032 Whistler are round cabinet knobs; in the Emtek SELECT and Schaub collections there are also the Allerton, the Art Deco, and the Astoria glass knob for a period look. For a heavier traditional round with a groove detail, the Deltana KRB175 at 1-3/4 inch diameter is a step up in scale from the Quadrato's 1-3/8 inch.
8) Are the Emtek Schaub Collection knobs the same thing as the Schaub Quadrato?
Not the same product. The Emtek SELECT 8665, Allerton, Art Deco, and Astoria knobs are carried under a Schaub Collection heading, but each is its own series with its own profile, and they are catalogued as knob/pull items rather than the square Quadrato knob. If you need to match existing Quadrato knobs on a cabinet run, order the Schaub 20015 in the same finish code; do not substitute across those Emtek series expecting the profile to match.
9) Which cabinet knobs are closest in function to the Schaub 20015 for a straight one-for-one swap on kitchen cabinetry?
The Schaub 20015 Quadrato is built purely as a cabinet knob for doors and drawers. The nearest like-for-like items by function are the Orca Hardware CK-18032 Mission and the Orca Hardware CK-19032 Whistler, both catalogued with a cabinet knob function. The Emtek Schaub Collection items such as the 8665 Select are listed as a cabinet knob/pull, so confirm the piece you receive is the knob format before swapping it onto a knob-drilled door.
10) Is the Schaub Quadrato knob suitable for commercial cabinetry, or is it residential only?
It is used in both. The 20015 is specified for kitchen cabinetry, bath vanities, built-in millwork, and commercial casework. The thing to weigh for high-cycle commercial drawers is the zinc base material with plated finish rather than solid brass. Where that matters, the Delaney solid brass knob is the swap.
