F&L Saddle-Type Support for Flexible Ducts: High-strength zinc metal strap that prevents sagging, improves HVAC airflow, and is compatible with durable air conditioning systems

Stop Sagging Ducts and Restore Full Airflow with F&L Duct Saddle Hangers Sagging flexible ductwork is one of the most common causes of poor HVAC performance, increased energy bills, and uneven heating and cooling throughout the home. When flex duct droops between supports, it creates kinks, restricts airflow, and forces your system to work harder. The F&L Duct Saddle Hanger is the simple, professional-grade solution. Built to Last — Engineered for Performance Manufactured from premium zinc-coated metal, F&L Duct Saddles deliver the strength and corrosion resistance HVAC professionals demand. The galvanized finish protects against rust in humid attics, damp basements, and unconditioned crawl spaces — making these saddles a reliable long-term support for any flexible duct installation. Smart Wide-Saddle Design Unlike narrow wire or strap hangers that pinch and damage flex duct, the F&L Duct Saddle features a wide, smooth-contoured profile that cradles the duct and distributes its weight evenly. This protects the inner liner, preserves insulation integrity, and keeps the duct at its full design diameter — exactly what's needed for optimal static pressure and air flow. Compliant with industry standards for proper flex duct support spacing.
