Improved Airflow, Intake & Comfort: The modern register grille with corrosion-resistant design ensures controlled, even air flow from your HVAC system, preventing uneven heating or cooling. It stops air from escaping haphazardly, eliminating concentrated blasts and ensuring a comfortable, consistent temperature throughout the room. Dimensions: Outer dimensions of the grille (including the bezel) - 12.80" x 2.95" inches. The flange connector is 12" x 2.16", for a secure, tight connection fit. Compatible with various round spiral ducts, ranging from a minimum of 6.29" to a maximum of 15.74" inches (duct diameter). Simple Installation: Mount the grille along the length of the round or spiral air duct, align it in the opening and secure it in place using screws (screws included). Once installed, manually adjust the louvers to control airflow direction and enjoy improved comfort and efficiency. Engineered to accommodate a range of duct sizes, ensuring versatility for diverse applications and duct dimensions. Reliable Seal & Precise Airflow Control: The duct opening air vent cover features a bezel flange that ensures a tight seal around the duct, while the adjustable blades allow you to direct airflow precisely where it's needed, either evenly across the room or focused in a specific direction, for enhanced comfort and efficiency.
