This Omega National liner is the metal interior component that bridges the SUT90870M wood hood shell and its ventilation unit, providing the structural housing that allows both pieces to function as a finished, integrated range hood.
A wood range hood is built from three distinct parts: the decorative outer shell, the liner, and the ventilator that moves air. The liner is the middle piece. It fits inside the wood shell and creates the housing cavity that a compatible ventilator mounts into, so the shell, liner, and ventilator work together as one complete hood installation. Without the liner, the shell has no structured opening to accept the ventilator. This T-shaped straight liner provides that connection for the SUT90870M.
The liner carries a Silver Metallic finish, which sits inside the hood where it faces the ventilator and duct connection rather than the kitchen. The T-shaped profile and straight design follow the geometry of the SUT90870M shell, so the liner drops into place with the correct orientation. The 9-7/16 x 10-3/16-inch center hole is the pass-through for the ventilation unit. Dimensions are precise rather than approximate: the 40-7/16-inch width and 18-1/4-inch depth are the fit specs that determine whether the liner seats flush in the shell.
This liner suits an installer or cabinetmaker completing a wood hood installation using the Omega National SUT90870M shell and a compatible ventilator. It is also the right part for a replacement situation where the original liner needs to be swapped out on an existing SUT90870M installation. Because the liner is matched to a specific shell by model, confirm the hood model before ordering. The decorative wood shell and the ventilation unit are each separate purchases.
No. This liner is designed specifically for the Sirius SUT90870M. Confirm the shell model before ordering, since liner dimensions and profiles vary across Omega National hood families.
The ventilator is a separate purchase. This listing is for the liner only, which is the metal housing component that fits inside the wood shell and accepts the ventilator.
No. The decorative wood shell is a separate product. This liner is the interior metal component that sits between the shell and the ventilator in the assembled hood.
The 42-inch liner size is the nominal designation matching the SUT90870M hood series. The 40-7/16-inch width is the actual measured dimension. Use the actual width when planning the installation.
Specify this liner to complete an Omega National SUT90870M wood hood installation with confidence that the ventilator has a properly sized, correctly profiled housing to seat into.
