Schaub 659-AD 1-7/8" x 1-1/4" Square White Mother of Pearl Diamond Avalon Bay Cabinet Knob

The body is solid brass, which is what carries the load and the screw threads. The face is a natural shell inlay from Schaub's Symphony Inlays line, so it's a decorative surface, not a scratch-resistant one. For high-turnover multi-family or heavy commercial cabinetry, an all-metal knob like the Deltana KRB175 solid brass round knob or the Orca CK-18032 Mission round knob gives you a face with nothing to chip.

The Schaub 659 Avalon Bay knob is a solid brass knob in the Symphony Inlays style, with a mother of pearl face. For a plain brass knob with no inlay, the Delaney Solid Brass Cabinet Knob and the Deltana KRB175, a heavy-duty round knob with a groove in a 1-3/4 inch diameter and solid brass construction, both give you brass without a decorative face. The Deltana at 1-3/4 inch is close in size to the Schaub's 1-7/8 inch knob diameter, so the visual footprint on the drawer front stays similar.

Projection is 1-1/4 inches off the face. The knob itself is 1-7/8 inches across with a 7/8 inch base footprint where it meets the door, so on a narrow stile or a tight galley run, check swing clearance against opposing doors and appliance handles.

Both are Aged Dover finish over solid brass with a shell inlay: 659-WP-AD is white mother of pearl, 659-YP-AD is yellow mother of pearl. Same body, same size, only the inlay color changes, so you can mix them across upper and lower runs if you want contrast.

It's a single-screw knob, so one bore through the door or drawer front is all the prep it needs. If you're replacing bar pulls with two holes on center, you'll have a spare hole to plug and finish.

No, they are different shapes. The Schaub 659 is a square knob with a 1-7/8 inch knob diameter, a 7/8 inch base dimension and a 1-1/4 inch projection, with a mother of pearl inlay face. The Deltana KRB175 is a round knob with a groove at 1-3/4 inch diameter in solid brass. Both are single-screw cabinet knobs, but if you are matching an existing run of square Avalon Bay knobs the Deltana will read as a different profile on the door.

Yes. Emtek lists several cabinet knobs under its Schaub Collection, including the Emtek 8665 Select cabinet knobs in the Emtek SELECT series, the Allerton cabinet knob, the Art Deco cabinet knob, and the Astoria glass cabinet knob. All four are catalogued as cabinet knob/pull function, so they cover the same cabinet duty as the Schaub 659 Avalon Bay knob while keeping the specification under the Emtek name.

The Schaub 659-AD uses a mother of pearl inlay face, which is a natural material with its own variation from piece to piece. If you want a uniform look across many units, the Orca Hardware CK-18032 Mission round cabinet knob and the Orca CK-19032 Whistler cabinet knob are both cabinet knob function and have plain metal faces, so repeat orders match one another more predictably.

The Schaub 659 Avalon Bay knob is offered with a White Mother of Pearl or a Yellow Mother of Pearl face, both opaque shell. For a translucent face, the Emtek Astoria glass cabinet knob in the Schaub Collection uses glass instead of shell and is catalogued as cabinet knob/pull function, so it mounts to a drawer or door front the same way.

The Schaub 659 Avalon Bay knob takes an 8/32 by 1 inch machine screw, which is the standard cabinet knob thread. The Emtek Allerton and Art Deco cabinet knobs in the Schaub Collection are single-point cabinet knob/pull items as well, so they land in a single bored hole rather than a two-hole pull pattern. Confirm the screw length against your drawer front thickness on any swap, since a thicker front or added panel can call for a longer screw.

Yes. Schaub publishes a Proposition 65 warning for this knob, linked from their product stewardship page. If you're shipping into California on a commercial or multi-family order, plan on passing that notice through.
