Schaub 664-IM 1-1/2" x 1-1/4" Imperial Shell Cabinet Knob

It mounts with a standard 8-32 machine screw, which is the common cabinet knob thread in North America. If your doors and drawer fronts are already drilled for single-hole knobs on 8-32 screws, the Imperial Shell knob drops straight into that prep. Screw length is the only thing to watch: thicker drawer fronts or doors with added panels may need a longer 8-32 screw than the one that came off the old knob.

The Schaub 664-IM is a solid brass cabinet knob measuring 1-1/2 inch by 1-1/4 inch with a 1 inch projection and an 8/32 thread. If you want another solid brass knob, the Deltana KRB175 is a heavy-duty solid brass round knob with a groove in a 1-3/4 inch diameter, and Delaney also offers a solid brass cabinet knob in its Cabinet Knobs series. Both are plain round profiles rather than the shell-shaped Symphony Inlays styling of the 664-IM.

They are related but not interchangeable. The Schaub 664-IM is the Imperial Shell knob in the Symphony Inlays style. Emtek lists several knobs under its Schaub Collection, including the Emtek 8665 Select, the Allerton, the Art Deco, and the Astoria Glass cabinet knobs, and each of those is its own series with its own profile. If you are matching existing Imperial Shell knobs on a kitchen, order the 664-IM rather than an Emtek series knob.

Projection is 1 inch, with a 1/2 inch base at the door face. That matters where cabinets sit close to an appliance, a wall return, or an island walkway, because a 1 inch projection is what your knuckles and pant pockets have to clear.

Solid brass, finished in Polished Nickel. Solid brass gives you the weight and thread strength you want on a knob that gets pulled thousands of times a year, and polished nickel is a bright, cool-toned plate that shows fingerprints more than a satin finish does. Polished Nickel (PN) is the finish this knob is built in.

The 664-IM belongs to Schaub's Imperial Shell collection within the Symphony Inlays style line, so it is designed to run alongside the other Symphony Inlays pieces. Emtek also carries the Schaub Collection under its SELECT line, including the Emtek 8665 Select cabinet knobs, if you are filling out a job with more pieces in that family.

Staying in the same single-hole knob format, the Emtek Art Deco and Emtek Allerton cabinet knobs (both Schaub Collection) give you a different profile, the Emtek Astoria is a glass knob, and the Orca Hardware CK-19032 Whistler is another cabinet knob option. For plain solid brass without the inlay look, Delaney's solid brass cabinet knob is the simpler choice.

The Schaub 664-IM belongs to the Imperial Shell collection in the Symphony Inlays style, so it is a decorative shell form. For a plainer profile, the Orca Hardware CK-18032 Mission round cabinet knob and the Orca CK-19032 Whistler cabinet knob are both straightforward cabinet knobs, and the Deltana KRB175 is a simple round knob with a single groove.

The Schaub 664-IM measures 1-1/2 inch by 1-1/4 inch. For a larger grip, the Deltana KRB175 is a 1-3/4 inch diameter heavy-duty solid brass round knob with a groove, which gives you more to hold on a wide drawer front while staying in solid brass.

The Schaub 664-IM is specified as a cabinet knob. If you want a piece catalogued to work as either, the Emtek Allerton, Art Deco, Astoria Glass and 8665 Select pieces in the Schaub Collection are all listed with a cabinet knob/pull function.

Polished Nickel (PN) is the finish the 664-IM is built in. If your job is specified in an oil-rubbed or satin tone, you are looking at a different Schaub model number rather than a finish option on this one.
