Range Hood Liner 36 Arched For Sirius Use

Range hood liner 36 arched is identified as WBSC - 1573 - NP09081AS36SM1 and is manufactured by Omega National Products as a wood range hood liner component. This liner is described as a notched hood liner in a silver metallic color, so it creates a defined, finished metal surface inside the hood cavity where the power module sits. The liner is for a Sirius SUT90870M power module, so it is shaped and notched to work with that specific opening geometry in a wood range hood design. The opening is specified as 19-7/16 x 10-3/16 inches, which sets the cutout size the Sirius module needs, giving fabricators a clear target for building or modifying the hood structure. The product is classified as a range hood liner, so it serves as the metal transition between the wood hood body and the power module for a cleaner, more controlled installation zone.

Key Liner Details That Support Hood Builds

• The SAP description defines this part as a 36 arched liner, so it is oriented to work in wood range hoods designed around a 36 inch arched profile, helping installers match the liner to the hood width during layout.
• The liner is specified for use with the Sirius SUT90870M power module, so its cutout and notching pattern are built around that module, which supports precise positioning of the blower unit in the hood shell.
• The opening size is given as 19-7/16 x 10-3/16 inches, so the necessary cutout in the wood hood can be sized accurately to receive the module without guesswork, aiding both shop fabrication and field fitting.
• The liner is described as silver metallic color and powder coated, so the visible metal interior presents a consistent finished surface, which matters when the underside of the hood is exposed in kitchen use.
• Omega National Products is listed as the brand and the product is in the range hood liners class, so it is intended as part of a wood range hood assembly rather than a standalone hood, shaping how it is specified in project plans.

Arched Liner Fit And Opening Layout Details

The SAP description states this is a 36 arched liner for a Sirius SUT90870M power module, so layout starts with a hood body sized around a 36 inch span and an arched design profile. The web description notes that this is a notched hood liner, which means the metal piece is pre-formed with cut geometry to receive the power module, reducing layout complexity at the metal interface. The opening of 19-7/16 x 10-3/16 inches dictates the cutout size required in the hood interior for the Sirius module, and this fixed dimension lets shop drawings be based directly on the liner specification. Because the product is categorized as a range hood liner for wood range hoods, it is intended to be integrated into a custom or semi-custom wood hood configuration where the liner defines the metal interior boundary.

Using This Omega National Range Hood Liner In Projects

Where This Notched Hood Liner Is Applied

This Omega National Products component is categorized under wood range hoods as a range hood liner, so it is applied inside a wood kitchen hood structure rather than on a wall by itself. The SAP and web descriptions both identify it as a 36 arched liner for the Sirius SUT90870M power module, which places it specifically in projects where that blower module is used. Because the liner has a defined opening of 19-7/16 x 10-3/16 inches, it effectively controls the interface where the Sirius unit meets the wood hood, aligning the blower location within the cavity. The notched design mentioned in the web description means the metal is shaped to work with this application, so fabricators can plan the wood framing and panel work around a known metal part geometry for more predictable assemblies.

Why The Powder Coated Silver Finish Matters

The web description states the hood liner is silver metallic color and powder coated, so the visible metal interior has a uniform appearance that reads as a consistent finished surface when the hood is viewed from below. Powder coating provides a continuous, bonded finish layer over the metal, which means the inside of the hood takes on a single color tone that coordinates with the Sirius SUT90870M module face. Because the liner is intended for wood range hoods, having a defined silver metallic interior surface provides a visual transition between the wood structure and the mechanical power module, so the installation looks more integrated. The liner classification also signals that this metal shell defines the cooking zone boundary inside the hood, and the silver metallic finish helps that zone stand out clearly during layout and alignment of the power module inside the hood body.

Installer Questions About This Specific Hood Liner

Select This Liner For Sirius SUT90870M Hood Builds

This liner is defined as a 36 arched range hood liner from Omega National Products for the Sirius SUT90870M power module, so it fits projects centered on that module in a wood hood. The notched design with a 19-7/16 x 10-3/16 inch opening provides a fixed metal interface that guides hood cavity layout and module placement. The silver metallic, powder coated finish gives the hood interior a consistent metal appearance, which supports clean visual results around the power module area. For wood range hood builds using the Sirius SUT90870M, this part number aligns the liner, opening size, and finish into a single specified component for planning and ordering.
