MagX Magnetic Vent Cover 8x17 Inch – Ultra Thick 60 mil, Flexible Anisotropic Magnet

Overview

MagX Magnetic Vent Cover delivers a sturdy, low-profile solution for controlling airflow at the source. This pack includes two 8x17 inch sheets that can be trimmed to fit a range of vents—from floor registers to ceiling diffusers. The magnetic layer is ultra thick, delivering a reliable hold on steel surfaces while remaining discreet enough to blend with your space.

The system uses a flexible anisotropic magnet paired with a 60 mil (1.5 mm) magnetic layer to grip steel vent surfaces without slipping, even in high-traffic areas. A quick magnet test is recommended to verify compatibility with your vent material before applying the cover.

Key benefits

• Potential energy savings by limiting airflow to unused spaces when vents are closed or sealed.
• Customizable fit — trim with scissors for a snug seal on virtually any vent size.
• Versatile installation — suitable for floor, ceiling, and wall vents in homes or RVs, and compatible with HVAC or furnace vents.
• Reliable, non-slip adhesion on steel vents, designed to stay in place during normal use.

Usage tips

• Test the vent material with a magnet to confirm steel compatibility before applying.
• Measure, mark, and trim the cover to the exact vent size for a clean seal.
• Place the magnet-facing side onto the steel vent surface and achieve a secure hold.
• Remove or reposition as needed to adjust airflow without tearing the vent.

Notes: The magnetic side is designed to work with steel vents; aluminum, plastic, or wood surfaces may not attract the magnet. The two sheets offer flexible installation options for homes, RVs, and HVAC systems.
