Seatern Magnetic Vent Covers - Ultra Thick 60mil, Extra Strong Magnets, 4 Pack, 3.5" x 13.75"

Seatern Magnetic Vent Covers: Superior Seal and Easy Airflow Control

Engineered for steel vents, Seatern Magnetic Vent Covers offer a robust, repeatable seal while preserving a clean, low-profile look. The ultra thick 60 mil construction combined with high-strength magnets helps keep vent openings closed when you want to redirect airflow or block air in unoccupied spaces. The result is a practical solution that blends functionality with everyday comfort.

Key benefits at a glance

• 650 Gauss surface magnetic strength for a dependable seal on steel vent faces.
• Dimensions of 3.5 in by 13.75 in with rounded corners; trim easily to fit your vent face.
• 60 mil thickness for durability in active living spaces and busy households.
• Not designed for aluminum or plastic vents; verify vent material before ordering.
• Includes a four-pack to cover multiple registers for a cohesive look.

In real-life scenarios, imagine a cool breeze staying contained in a studio apartment or a warm room staying comfortable in a basement workshop. The covers also help direct airflow where you want it, instead of letting it drift into spaces you don’t need heated or cooled.

How it works and where it shines

The Seatern vent covers rely on a powerful magnet to grip steel vent faces securely, creating a tight seal that minimizes slip and gaps. This makes them suitable for various settings, from homes to RVs and heater vents, while remaining unobtrusive in design. Important notes: these are intended for steel vents only, and a quick magnet test on a small area can help confirm compatibility before purchase.

Size and fit details help you plan ahead. The standard footprint is 3.5 in by 13.75 in with rounded corners; you can trim to your preferred size if needed. For other sizes, check the listing image 6 for a detailed SIZE CHART and trimming guidance.

• Easy trimming with common household scissors to tailor coverage to your vent face.
• Ideal for home HVAC systems, basements, furnace vents, RVs, and shared living spaces where quiet operation matters.

What you get is a four-pack that supports a cohesive look across rooms, delivering consistent performance and a simple installation experience. While results vary by space, users may experience more controlled airflow and a cleaner aesthetic compared to open vents.
