Description

This duct transition connects a rectangular hood plenum to a round duct, providing a secure path for exhaust air and restoring proper ventilation performance. It's a direct-fit replacement designed to match original blower openings. What it does:

• Adapts a rectangular exhaust opening to standard round ducting for proper vent routing
• Maintains airflow from the range hood blower to the house duct system
• Prevents leaks and backflow when properly sealed to the hood and duct
• Helps eliminate reduced suction or noisy airflow caused by damaged or missing transitions

What's included: One rectangular-to-round duct transition piece. Install notes:

• Disconnect power to the hood before installing or servicing components
• Secure transition to the hood plenum and duct with sheet-metal screws and/or approved fasteners
• Use foil HVAC tape or approved duct sealant to ensure an airtight connection
• Wear gloves and eye protection when handling sheet metal to avoid cuts
