HMMAGNETS Powerful Magnetic Vent Covers (2-Pack), for Sealing Floor/Wall/Ceiling Registers of Width 11.25" to 12", Length 11.25" to 12" - White

Take control of airflow in your home with HMMAGNETS Magnetic Vent Covers, designed to seal unused vents and improve comfort room by room. These white magnetic vent covers are suitable for floor, wall, and ceiling registers, making them ideal as magnetic vent covers for floor use in basements or storage areas, vent covers for wall registers in spare rooms, and magnetic vent covers for ceiling installations where airflow needs to be fully blocked. Each pack includes three reusable covers that blend cleanly with your space while helping limit unwanted hot or cold air in unused rooms. Each magnetic vent cover is engineered with hidden rare earth neodymium magnets that provide strong, end-to-end holding power across the entire surface. This design allows the vent cover to stay firmly in place without slipping, shifting, or falling off, even when used as ceiling vent covers with strong airflow. These magnetic vent covers for ceiling, wall vents covers, and magnetic vent covers for floor applications are designed for magnetic steel vents only and will not work on aluminum, plastic, or wood vent surfaces. Each cover is designed to fit vents with faceplate widths between 11.25 inches and 12 inches and lengths between 11.25 inches and 12 inches. Choosing the correct size is essential for proper performance, and the covers should not be cut, as altering the size may damage internal features. The reusable design makes each vent cover easy to install, remove, and clean, and every set includes three magnetic vent covers, a step-by-step user guide, and a storage box for covers not currently in use.
