36 inch Signature Series chimney from Omega National Products is a cut-to-size wood chimney designed for Signature Series wood range hoods. This chimney is engineered as a trimmable extension above the hood, so installers can cut it to match the required finished height at the wall. Rift white oak construction delivers a consistent straight-grain appearance, which helps finishing workflows where a uniform rift pattern is desired across the kitchen. The chimney is purpose-built for 36 inch wide Signature Series wood hoods, so the proportions align with that hood width in typical wall installations. As part of Omega National's Signature Series, the chimney is matched to that hood line, helping maintain a coordinated look when pairing hood and chimney components on the same project.
This trimmable chimney is sold as a cut-to-size component in the Signature Series, so it is intended to be trimmed down from its starting height to meet the final installation dimension above the hood. With available heights of 23-1/2 and 31 inches across the cut-to-size chimney line, installers can select a starting size that keeps trimming within a comfortable range while still reaching the desired finished height. The design targeting 30, 36, 42, and 48 wide hoods means the chimney concept is structured around these standard hood widths, streamlining planning across different cabinet runs.
This Omega National Products chimney is part of the Signature Series wood range hood system, so it is intended to be installed above Signature Series wood hoods in kitchen or bath cabinetry layouts. The cut-to-size design focused on 30, 36, 42, and 48 wide hoods makes it suitable for runs where those hood widths are specified, such as standard 36 inch cooking centers or larger focal hoods at 42 or 48 inches. Because the chimney is available in 23-1/2 and 31 inch starting heights, it can be used in spaces with different ceiling elevations, from lower ceiling kitchens to taller wall conditions where more vertical extension above the hood is preferred.
Rift white oak construction positions this chimney for projects where rift white oak cabinets, panels, or moldings are specified, helping maintain a continuous visual grain character across doors, face frames, and the hood assembly. The Signature Series branding ties the chimney back to Omega National's coordinated wood range hood program, supporting consistent design language when specifying multiple Signature Series components on the same job. As a chimney for wood range hoods, it plays the visual role of extending the hood body upward, giving the installer a defined piece to trim and finish as part of the overall hood elevation.
The cut-to-size chimney format allows the installer to work from a full-height piece and then establish the final dimension on site, which can reduce alignment issues when ceiling heights or finished dimensions vary slightly from drawings. By offering starting heights of 23-1/2 and 31 inches, the product line provides enough material to reach typical wall heights while still leaving room to trim for precise alignment with surrounding cabinetry or crown details. The fact that these chimneys are specifically designed for 30, 36, 42, and 48 wide hoods also means the visual scaling is thought through for those widths, supporting a balanced look between the hood body and the chimney extension.
Rift white oak as the specified material helps finishing crews because the straight, linear grain tends to take stains and clear finishes with a consistent appearance along the height of the chimney, supporting a unified look from hood to ceiling. Being made in the USA contributes to predictable manufacturing practices, which matters when a clean joint between hood and chimney is expected as part of a premium wood hood installation. For installers and shops working repeatedly with Omega National's Signature Series, using a dedicated Signature Series chimney supports repeatable results from project to project.
