Use this Stainless Steel piece to cover your ducting work over your 18" Euroline Pro Range Hood (for EPTH18 Models). Duct Cover sizes are available to accomodate two ceiling heights: 8' and 9' ceilings.
Note that the Duct Cover is not a hood, but an extension which runs from your hood to your ceiling, creating a streamlined look which conceals the hood's ventilation ducts.
