Schaub 657 1-5/8" x 1-1/8" Fair Isle Imperial Shell Cabinet Knob

Yes, in most cases. It mounts with a single 8-32 screw through one bore, the same single-hole pattern nearly every cabinet knob uses, so it drops into an existing knob hole without new drilling. The one thing to watch is the 3/8 inch base footprint, which may not fully cover marks or finish shadow left by a much larger previous knob.

The Schaub 657 is a solid brass oval knob from the Fair Isle collection in the Symphony Inlays style, with an Imperial Shell inlay face. For an undecorated solid brass knob in the same material, the Delaney Solid Brass Cabinet Knob is a straight brass cabinet knob, and the Deltana KRB175 is a heavy-duty solid brass round knob with a groove at 1-3/4 inch diameter, slightly larger than the 657's 1-5/8 inch knob diameter. Both give the brass body without an inlaid face.

Projection is 1 inch from the face of the door, with a 3/8 inch base. That's enough clearance for fingers on an inset or overlay door, and it's worth checking against anything that swings past the knob, like an adjacent appliance panel or a door in a corner run.

The body is solid brass, and the face carries an Imperial Shell inlay. It's part of Schaub's Symphony Inlays line, where a natural inlay material is set into a brass knob body. Because each shell piece is natural, expect slight variation in color and figure from knob to knob across a kitchen run.

Two: Polished Brass (PB) and Polished Nickel (PN). Both are warm or bright polished metals, so if the rest of the kitchen is satin nickel or matte black, this knob won't match and you'd want a different Schaub collection.

It's an oval knob, 1-5/8 inches on the long dimension by 1-1/8 inches across. That elongated shape reads differently than a plain round knob and gives a bit more to grip on a heavy drawer. If you want a straight round profile instead, the Orca Hardware CK-18032 Mission round knob is that shape.

The 657 sits in Schaub's Fair Isle collection within the Symphony Inlays style, which is built as a coordinated family so knobs and pulls share the inlay treatment. If you want a similar decorative look from another maker we carry, Emtek's Schaub Collection pieces cover the same territory, including the Emtek Astoria Glass Cabinet Knob for an inset-material look and the Emtek Art Deco Cabinet Knob for a period profile.

For heavy-turnover or commercial use, no. The natural shell inlay is a decorative face that will show wear and cleaning-chemical damage faster than plain metal. For those openings go with an all-metal knob such as the Deltana KRB175 heavy-duty solid brass round knob at 1-3/4 inch diameter. Save the 657 for residential kitchens, baths, and millwork where appearance drives the choice.

The Schaub 657 reads as a shell-inlay oval knob in the Symphony Inlays style, which suits a decorative or coastal kitchen. For a craftsman or lodge look, the Orca Hardware CK-18032 from the 18-Mission Collection is a round cabinet knob with mission styling, and the Orca CK-19032 Whistler is another round cabinet knob in a rustic collection. Both are cabinet knobs with the same function as the 657.

The Schaub 657 uses an Imperial Shell inlay on a solid brass oval body. For a comparable decorative face in glass, the Emtek Astoria Glass Cabinet Knob in the Schaub Collection is a glass-faced cabinet knob, and the Emtek Art Deco Cabinet Knob offers a patterned metal face if you want detail without shell or glass. Both are cabinet knob/pull items rather than plain round brass.

Yes. Schaub publishes a Proposition 65 warning for this knob, linked through their product stewardship page. Buyers shipping into California should note it on the submittal.

The Schaub 657 is an inlaid Fair Isle knob offered in Polished Brass and Polished Nickel, which makes it a design selection for a feature kitchen or millwork package. For repeatable fleet-wide standardization, a plain round profile is easier to re-order across turns: the Delaney Solid Brass Cabinet Knob and the Orca CK-18032 Mission round cabinet knob are both simple round-body cabinet knobs. The 657 remains the choice when the specification calls for the shell inlay.

The Emtek Allerton Cabinet Knob is part of the Allerton series in the Schaub Collection and functions as a cabinet knob/pull, so it installs in the same single-hole cabinet prep. It is a different design family from the Fair Isle Imperial Shell pattern of the Schaub 657, so it will not visually match existing 657 knobs on the same run. Use Allerton when you are specifying a full new set, not when replacing one or two 657 knobs.
