💡 How do serious woodshops seal off dead ducts to boost actual CFM output? You can stop wasting motor power by capping unused lines on your main header tube. - Closed connectors stop air from rushing back through empty branch pipes - Airtight rubber gaskets keep fine sawdust trapped inside the main line - Pushed on caps hold steady under heavy vibration while sanding hardwoods - Directing full airflow helps grab coarse chunks faster near the cutter head
