Range hood liner 42 arched describes this Omega National Products liner designed as a shaped insert for a wood range hood. The arched configuration helps define the internal capture area, which matters when placing the Sirius SUT90870M power module so air is drawn through the intended opening instead of spilling into unlined cabinet space. The product is identified as a range hood liner within the Wood Range Hoods category, so it acts as the finished interior surface where the blower unit sits. That keeps the structural wood of a kitchen hood separated from the power module cavity, which is important whenever a Sirius SUT90870M is used inside a wood housing. The SAP description confirms it is a liner specifically matched to a 42 inch arched hood, so installers can select it when that hood form factor is required on a job.
The liner has an opening specified at 19-7/16 inch by 10-3/16 inch, which ties directly to the Sirius SUT90870M power module size and tells the installer where that module will seat inside the arched hood. Because the product is a 42 inch arched liner, its outside form is aligned with a 42 inch arched wood range hood project, letting fabricators design the hood body around a known liner footprint. The notched hood liner description signals that portions are preset to clear necessary areas around the Sirius module, so installers can focus on integrating duct and electrical connections without reshaping the liner cutout.
The web description states that this is a notched hood liner in a silver metallic color, powder coated for the Sirius SUT90870M power module, so it acts as a formed insert around that specific opening to receive the module. The stated opening of 19-7/16 inch by 10-3/16 inch corresponds to the Sirius SUT90870M power module opening, which gives a clear geometry for setting the module into the liner without guessing the cutout dimensions. The SAP description notes the liner as 42 inch arched for SUT90870M, which anchors this part in projects where a 42 inch arched wood hood is designed around that same Sirius power module.
The manufacturer part number 09080AS342SM1 and the Wurth Baer Supply WBSC - 1573 - NP09081AS42SM1 naming provide a defined part identity, which allows shops and installers to reference the exact 42 inch arched liner required for a Sirius SUT90870M layout. Because the liner belongs to the Range Hood Liners product class under Wood Range Hoods, it is oriented toward creating a consistent internal shell whenever a wood hood structure is built around a Sirius SUT90870M. The silver metallic powder coated finish stated in the description gives the interior a uniform surface, which matters when a visible underside is desired beneath the hood where the power module and liner are both seen in the finished kitchen. The notched configuration and precise opening dimensions work together so repeated builds of similar arched hoods can follow the same liner-based cutout geometry.
The liner is described for the Sirius SUT90870M power module, so its opening size and notched shape are arranged around that specific module footprint inside a wood hood.
The liner opening is listed as 19-7/16 inch by 10-3/16 inch, which defines the cutout area where the Sirius SUT90870M power module sets into the liner interior.
The SAP description identifies the part as a 42 inch arched liner, so it is configured around a 42 inch arched hood profile often used in wood range hood designs.
The web description notes a silver metallic color created by a powder coated finish, so the inside of the hood presents a continuous metallic surface around the power module.
The liner is from Omega National Products, so it fits into their wood range hood liner line distributed by Wurth Baer Supply.
The product is listed as a range hood liner in the Wood Range Hoods category, so it is intended as the interior liner component for a wood range hood assembly.
The SAP description directly ties this liner to a 42 inch arched hood layout for a Sirius SUT90870M power module, giving shops a defined interior part when planning wood hood builds. The stated opening of 19-7/16 inch by 10-3/16 inch and notched liner design supply fixed geometry around the power module cavity, so installers can match the liner to the Sirius unit and design the surrounding wood structure accordingly. The silver metallic powder coated finish provides a consistent interior appearance, which is useful when a visible silver interior is part of the project look. For projects using a Sirius SUT90870M inside a 42 inch arched wood hood, this Omega National Products liner offers a clearly defined interior component supplied by Wurth Baer Supply.
