48 inch Signature Series trimmable chimney describes a Rift White Oak chimney sized for Signature Series wood range hoods, so it provides a matching upper stack when you need a coordinated look above the hood body. The web description states that these cut-to-size chimneys are specifically designed to fit 30 inch, 36 inch, 42 inch, and 48 inch wide hoods, which lets one part number serve multiple standard hood widths on a project. The product name specifies Rift White Oak, so it delivers a rift-cut white oak face that aligns with common high-end cabinet materials. The category notes that this piece belongs to chimneys for wood range hoods, so it functions as the upper decorative section rather than the main hood body. The Omega National Products brand connection gives a consistent match to Signature Series wood range hoods in that line.
The web description states that these cut-to-size chimneys are available in a 23-1/2 inch height, so installers can trim from that starting dimension to align the hood stack with ceiling height or soffits. The product class is defined as chimneys for wood range hoods, meaning this piece mounts above a compatible wood hood shell to complete the vertical assembly. Because the chimneys are designed for 30 inch, 36 inch, 42 inch, and 48 inch wide hoods, a single height can be cut to work across different hood widths in the same room, keeping reveal lines consistent. The Signature Series reference ties this part to that hood series, so dimensions are coordinated for a clean transition between hood body and chimney.
The product name identifies a 48 inch Signature Series standard trimmable chimney in Rift White Oak, so it is suited to installations where the base hood is part of the Signature Series and specified in a similar width. The web description states that cut-to-size chimneys are designed to fit 30 inch, 36 inch, 42 inch, and 48 inch wide hoods, which allows this chimney type to be used across an entire kitchen project that mixes those hood widths. Because the category lists wood range hoods and the material is Rift White Oak, the chimney visually ties into wood cabinet runs that use the same species, supporting a unified elevation. The 23-1/2 inch height referenced in the description offers a proportional upper section for typical wall heights, and trimming from that height lets installers keep the hood crown at a consistent level across adjacent wall cabinets. The Omega National Products brand connection and Signature Series naming mean this chimney is intended to coordinate with that specific family of wood range hoods rather than unrelated designs.
The description notes that these are cut-to-size chimneys, so the 23-1/2 inch height can be reduced on site to suit ceiling conditions, which helps maintain a straight visual line even when room heights vary slightly. Because they are specifically designed to fit 30 inch, 36 inch, 42 inch, and 48 inch wide hoods, installers can standardize on one chimney approach while still meeting different hood widths, streamlining planning and reducing layout variation. The Signature Series standard trimmable designation means this component is dimensioned to relate directly to Signature Series hood bodies, which helps achieve tight joints and aligned profiles where the chimney meets the hood. Using Rift White Oak for this chimney, as specified in the product name and description, lets fabricators and installers coordinate stains or clear finishes with rift white oak cabinetry, reducing time spent adjusting finishes to hide species differences. The Omega National Products manufacturer reference and part number RCH487UF1 add clear identification in drawings and order lists, which supports repeatable reorders and consistent use across multiple jobs.
