Plastic Vent Covers - Cold Air Return
Rust proof plastic vent covers are the way to go for homes which experience high levels of moisture. Our cold air return can be used on your ceiling or wall to cover up any open ductwork to help direct the airflow. These plastic vent covers are made out of a high density polystyrene construction, making them scratch proof. For a classic cold air return look but at a way more affordable price, check out these contemporary grilles. The plastic vent covers have a faceplate which will measure about 1 1/4" larger than what is listed below.
The cold air return comes with screws that allow you to mount this unit over any open ductwork. No professional help needed! Virtually flat plastic vent covers do not have any dampers to close off airflow. For cold air returns which are not flat, check out this plastic baseboard grille.
