Schaub 664-MOP 1-1/2" x 1-1/4" Mother of Pearl Cabinet Knob

It's a genuine inlay. The knob body is solid brass in a polished nickel finish, and the mother of pearl is set into it as part of Schaub's Symphony Inlays styling. Because it's natural shell, expect variation in the pattern and iridescence from knob to knob, which is normal for inlay hardware and is why you order a full run at once rather than piecemeal.

Yes. It mounts on a single 8/32 screw through one hole, and the 1/2 inch base sits over that hole. Any standard single-bore cabinet knob prep takes it directly. What it will not do is cover a two-hole pull prep on center spacing; if you're converting drawers from pulls to knobs, you'll be filling and refinishing the old holes.

Projection is 1 inch from the face of the door or drawer. The base that sits against the wood measures 1/2 inch, and the knob itself is 1-1/2 inch diameter. That 1 inch stand-off gives a full grip for a hand, which matters on drawers in a tight galley or a passage where someone brushes past a run of cabinets.

Polished nickel is the only finish offered on the 664-MOP, paired with the mother of pearl inlay. If your job is specified in an unlacquered brass, oil rubbed bronze, or satin finish, this knob won't match and you'd want to look at a plain metal knob line instead. For matching adjacent pulls on the same run, stay within Schaub's Symphony program.

A 1-1/2 inch diameter is on the larger side for a wall cabinet door, where 1 to 1-1/4 inch is the common size, and it reads as a statement knob rather than a quiet one. On drawer fronts and on a pantry or island run it looks proportionate. A frequent approach is the 664 on drawers and a smaller knob or a pull on the upper doors, so long as the finish and inlay line up.

For a plain solid brass knob with no shell inlay, the Deltana KRB175 is a heavy-duty round knob with a groove detail at 1-3/4 inch diameter, or Delaney's solid brass cabinet knob line. If you want something with a design profile rather than an inlay, Orca's CK-18032 Mission round knob and CK-19032 Whistler knob are both straight cabinet knobs. None of those carry the mother of pearl look, so don't mix them into a run that already has 664-MOP on it.

Emtek carries the Schaub Collection, so the design families line up on the same program. Emtek's Astoria Glass cabinet knob is the closest in spirit if you want a decorative material set into a knob rather than a shell inlay, and the Emtek 8665 SELECT, Allerton, and Art Deco knobs are the other Schaub Collection options. Each of those is a cabinet knob/pull, so confirm the finish designation matches polished nickel before mixing them on one kitchen.

The body is solid brass, which holds up to repeated use better than a zinc or plated pot-metal knob, and it fastens with a single 8/32 machine screw that can be retightened rather than a wood screw that strips out. The consideration for high-turnover property is the mother of pearl inlay itself: it's a natural shell face, so it's a decorative element, not an abuse-rated one. For hard-use back-of-house or maintenance-heavy runs, a plain solid brass knob such as the Deltana KRB175 is the more forgiving choice.

The Schaub 664-MOP uses a mother of pearl inlay from the Mother of Pearl collection. For a different decorative face, the Emtek Astoria Glass Cabinet Knob in the Schaub collection uses glass, and the Emtek Art Deco Cabinet Knob offers a period styled profile. Both are catalogued as cabinet knob/pull items in the Schaub collection.

The 664-MOP sits in the Symphony Inlays style with a polished nickel body. The Emtek Allerton Cabinet Knob in the Schaub collection is the nearest traditional-profile alternative in the same design family, catalogued as a cabinet knob/pull. It carries no mother of pearl inlay, so the face reads as plain metal rather than the shell inlay of the 664-MOP.
