Use this Stainless Steel piece to cover your ducting work over your 18" Island Chimney Style Euroline Pro Range Hood (for EPITH18 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.
