Plastic Flex Duct Saddle – Load Distributing Support for Flexible Ductwork The Plastic Flex Duct Saddle is a purpose-built support designed to hold flexible ductwork without compression, sagging, or kinking. Unlike strapping alone, this load-distributing device cradles the duct evenly, maintaining its internal shape and allowing air to flow freely through the system. With a smooth concave profile, each unit provides up to 930% more surface contact area than traditional strapping methods. This eliminates “strap strangulation,” reduces static pressure, and has been tested to improve airflow by an average of 30%, helping HVAC systems operate more efficiently and reliably. By reducing airflow restrictions, these supports help shorten system cycle times, lower energy consumption, and reduce strain on critical components such as blower motors and compressors — improving comfort while extending system lifespan. Designed for Compliance & Performance In Australia, flexible ductwork must be supported using load-distributing supports to meet installation requirements. The Plastic Flex Duct Saddle helps installers meet these expectations while delivering measurable performance gains for residential, commercial, and industrial HVAC applications. Fast, Tool-Free Installation The patented strap channel allows the unit to be installed after strapping is already secured, making it ideal for both new installations and retrofits. Simply lift the duct, slide the saddle onto the strap, and lower the duct into place — no additional tools required.
