Schaub SCH-990 – Frequently Asked Questions

1) Is the Schaub 990 a knob a single screw mount, or does it need two holes like a pull?
It is a single-bore knob, 1-3/8 inches in diameter, fastened with one 8/32 screw. There is no center-to-center spacing to match because there is only one hole. Replacing a two-hole pull with it leaves a second hole to fill or cover.
2) I need matching cabinet knobs across a whole kitchen or a unit turnover. Is a shell inlay knob the right call?
Shell inlay is a natural material, so every 990 face varies in pattern and tone. That reads as a feature on a feature island or a bath vanity, and as an inconsistency across forty identical unit kitchens. For a fleet where every opening should look the same, a plain solid brass knob is the safer standardization: the Delaney Solid Brass Cabinet Knob or the Orca CK-18032 Mission round knob are single-material options in the same category.
3) I need to match Schaub cabinet knobs but the 990 inlay is not the look I want. What else carries the Schaub design?
Emtek sells several cabinet knobs under the Schaub Collection: the Emtek 8665 in the Emtek SELECT series, the Emtek Allerton, the Emtek Art Deco, and the Emtek Astoria Glass knob. Each of those is a cabinet knob/pull, so they cover the same job as the Schaub 990 while giving you a different face than the 990's Symphony Inlays shell.
4) How far does the Schaub 990 knob stick out from the cabinet door?
Projection is 1-1/8 inches off the face of the door or drawer front, with a 7/8 inch base where it meets the wood. That matters in a tight galley or where a drawer bank sits next to a wall return, and the 7/8 inch base is what determines how much flat surface you need around the bore.
5) What is the Schaub 990 knob actually made of, and is the shell part real?
The body is solid brass, and the face carries a genuine shell inlay from the Symphony Inlays line: Imperial Shell, Mother of Pearl, or Tiger Penshell depending on which finish you order. Solid brass rather than plated zinc is what makes this a residential-grade decorative knob for high-visibility cabinetry rather than a utility part.
6) What finish and inlay combinations does the Schaub 990 knob come in?
Three combinations, and the inlay is tied to the metal finish: Polished Nickel with Imperial Shell, Polished Nickel with Mother of Pearl, and Estate Dover with Penshell. If you want the darker Estate Dover metal, Penshell is the inlay that goes with it.
7) Can I use the Schaub 990 shell knob in a commercial or high-traffic setting?
It is a decorative cabinet knob with a natural shell face on a solid brass body, meant for cabinetry rather than heavy-use openings. Shell inlay scratches and abrades in a way solid metal does not, so for a break room, a nurses station, or anywhere hands hit hardware all day, an all-brass knob such as the Deltana KRB175 heavy-duty round knob is the more durable choice.
8) Will the Schaub 990 cover the marks left by the knob I am taking off?
The base that contacts the wood is 7/8 inch across, so it covers only that footprint. If the old knob had a wider rose or a backplate, any ring or unfinished area outside 7/8 inch will show. Same-size bore is not the issue, the 8/32 screw drops into a standard existing hole; the visible footprint is.
9) For a rental turn where the knobs get handled hard, is the Schaub 990 the right choice or should I use something else?
The Schaub 990 is a solid brass knob with a shell inlay face in Imperial Shell, Mother of Pearl, or Tiger Penshell, so the visible surface is a natural inlay rather than plain metal. If you want an all-metal face on a heavy-traffic unit, the Deltana KRB175 is described as a heavy-duty solid brass round knob with a groove, and the Orca CK-18032 Mission and Orca CK-19032 Whistler are cabinet knobs with plain machined faces. Those give you a uniform metal surface across a fleet of units.
10) Will an Emtek 8665 mount in the same hole as a Schaub 990?
The Schaub 990 uses an 8/32 thread screw size, which is the common cabinet knob thread, and it projects 1-1/8 inch off the face with a 7/8 inch base. The Emtek 8665 is a cabinet knob/pull in the Emtek SELECT series and mounts through a single bore the same way a knob does, so the hole pattern is not the obstacle. Confirm the projection and base diameter you want before swapping, since the base footprint is what decides whether an older knob's ring mark still shows on the door.
11) The Emtek 8665 and Allerton are called cabinet knob/pull. Is that the same thing as the Schaub 990?
Not quite the same scope. The Schaub 990 is a cabinet knob, a single-bore piece. The Emtek 8665, Emtek Allerton, Emtek Art Deco, and Emtek Astoria Glass are each listed with a cabinet knob/pull function, meaning the family covers pull configurations as well as knobs. If you are ordering to match single-bore knob boring already drilled in the doors, verify you are picking the knob configuration and not a pull from those families.
12) I am specifying a decorative knob for a millwork package. What are the alternatives to the Schaub 990 in a defined collection I can carry across the whole job?
The Schaub 990 sits in the Symphony Inlays style with Imperial Shell, Mother of Pearl, and Tiger Penshell inlays, offered in Polished Nickel with Imperial Shell, Polished Nickel with Mother of Pearl, and Estate Dover with Penshell. If you need a different collection to run across a package, the Orca CK-18032 belongs to the 18-Mission Collection and the Orca CK-19032 to the 19-Whistler Collection, while Emtek's Astoria and Art Deco are named series under the Schaub Collection. Picking a named series is what lets you extend the same design language to the rest of the millwork.
13) Which knob gives me a larger grip than the Schaub 990 for someone with limited hand strength?
The Schaub 990 measures 1-3/8 inch across the knob. The Deltana KRB175 is a 1-3/4 inch diameter round knob in solid brass with a groove around it, so it gives a wider face and a defined edge to catch a finger on. On cabinetry where grip matters more than the inlay detail, that difference in diameter is the deciding spec.
