We offer high quality White Vent Cover that is widely used in the industries. The rectangular shape of the product enables easy handling and installation. It is clear from their design that vent covers permit air to pass through them. Others have louvres that can be adjusted to change the airflow or direct it to a particular area of the room, while some are more grate-like in design. Additionally used for this purpose are air deflectors, which are placed on top of the covers.
