Upgrade your dust collection system with the Dustopper 36" Hose and 90-Degree Sweep Elbows – the ultimate airflow-boosting accessories for any dust collector or shop vacuum with a 2-1/2" nominal (2-1/2" actual OD) port. Why It Works: Traditional short-radius elbows and restrictive hoses can choke your vacuum system, leading to weak suction, increased clogs, and decreased efficiency. Dustopper's components are engineered for performance – delivering smoother air transitions, less turbulence, and significantly better suction at the tool.
