48 inch wall mount trimmable chimney describes a cut-to-size wood chimney that is designed to finish a Signature Series range hood cover in cherry, so the hood installation gains a coordinated wood extension above the main hood body. The product comes from Omega National Products under part number RCHT48CUF1, which ties it directly to their Signature Series wood range hood program and supports consistent component matching on a multi-hood job. As a wall mount trimmable chimney in cherry, it extends the aesthetic of cherry cabinetry upward above the cooking area, supporting a unified look in kitchen projects that specify cherry throughout. The product sits in the wood range hoods chimney class, so it is intended as the upper chimney section over the working hood shell rather than as a functional blower or liner component.
The cut-to-size design means this chimney is manufactured with extra length that can be trimmed down on site, so installers can tailor the final chimney height to suit the distance between the top of the range hood cover and the ceiling or soffit. With a 48 inch width designation in the SAP description, the chimney is sized to align across the face of a 48 inch wide hood, supporting flush visual lines when it is centered over a 48 inch cooktop or range. The 31.5 inch height spec gives an upper limit for layout, so field measurements can be taken off that dimension before any cut is made to establish final chimney exposure.
This Signature chimney is used above Omega National Signature Series range hood covers where a cherry wood upper section is desired, so the vertical transition from the hood to the ceiling reads as a continuous cherry assembly. Designed to fit 30, 36, 42, and 48 inch wide hoods within the cut-to-size program, it can be selected from the range to match a planned hood width, then trimmed so the visible width aligns with the hood cover below. On a 48 inch wide hood, the 48 inch W x 31.5 inch H cherry configuration from the SAP description gives the starting envelope, so the chimney spans the same width as the hood body for a clean, framed appearance over the cooking zone.
The chimney being cut-to-size means installers can work from the maximum 31.5 inch height and remove material until the top edge meets the ceiling line or a finished trim detail, which reduces the need to order custom heights for each ceiling variation. Having two general height offerings in the cut-to-size chimney group, 23-1/2 inch and 31 inch class, provides flexibility for projects with differing hood mounting heights, since installers can select the closer range and then trim for a precise finished dimension. The clearly defined 48 inch width specification in cherry helps layout, because the hood body and chimney share a uniform width reference, so cabinet lines and decorative trim can be planned around a known 48 inch span without guesswork. As a component within Omega National wood range hoods, this chimney plays the role of the visible upper enclosure above the hood, closing off the space between the hood cover and the structure while maintaining the cherry wood presentation.
This Signature chimney is specifically designed to fit Omega National Signature Series wood range hood covers in multiple widths, so it serves as the upper wood section above those hood bodies.
The cut-to-size chimney is produced with extra height, so installers trim it down on site to match the distance from the range hood cover to the ceiling, supporting accurate final height alignment.
The cut-to-size chimney program is specifically designed to fit 30, 36, 42, and 48 inch wide hoods, so it aligns with common residential hood width selections.
The SAP description lists this Signature chimney as 48 inch W x 31.5 inch H in cherry, establishing the outer width and maximum height for planning, layout, and trimming work.
The chimney is described as cherry, so its visible wood appearance is intended to coordinate with cherry cabinetry and Signature Series cherry range hood covers in the same project.
This cut-to-size Signature chimney is made in the USA, providing a domestic origin that can align with specifications calling for U.S.-manufactured wood hood components.
This Omega National Products Signature chimney, identified as 48 inch W x 31.5 inch H in cherry, pairs with Signature Series wood range hood covers where a coordinated cherry upper section is required. The cut-to-size configuration supports trimming in the field, so the final height aligns with your hood mounting elevation and ceiling conditions while maintaining a consistent 48 inch span over the cooking area. For projects built around cherry cabinetry and a 48 inch wide Signature hood, this chimney provides the defined dimensions and cherry finish needed to complete the wood hood assembly.
