  • DUCT REDUCER & INCREASER: Mitchell Metal HVAC Duct Reducer is designed for flexible or metal HVAC ducts and air vents, seamlessly connecting two air ducts of different diameters. Ideal for both DIY enthusiasts and professional tradespeople, our sturdy steel ducting ensures long-lasting performance. Note: For use with gas heating, ventilation, and air conditioning only. Not suitable for solid fuel venting and comes with non-crimped ends.
  • PREMIUM-QUALITY METAL SHEET: Our duct reducers and increasers are crafted from high-quality galvanized steel, making them perfect for both flexible duct and rigid sheet metal duct applications. This single-wall galvanized metal reducer ensures you are never limited by your air conditioner's ducting requirements, offering a robust solution for both professionals and homeowners. Easily drillable with self-drilling screws.
  • SUPERIOR STRENGTH AND FITTINGS: These galvanized duct reducers/increasers can be used with fans, ducting, air-cooled hoods, and ventilation systems, allowing you to extend and adjust your ducting as needed. They are ideal for changing duct sizes while maintaining optimal airflow for maximum efficiency in your HVAC system.
  • SIMPLE INSTALLATION: Think of these reducers as a bridge between your current unit and the new ducting. Their design makes it easy to match up different sizes, ensuring the best airflow and efficiency for your HVAC system. Compatible with both flexible duct and rigid sheet metal duct, they can be secured using montage glue, tape, or steel clips for a secure connection.
