Our take on the Square Magnetic Vent Covers 12" x 12", 2 Pack

These are 12-inch square magnetic register covers sold as a two-pack. They snap onto steel floor, wall or ceiling vents to block airflow, cut drafts and reduce noise between rooms. The rubber-magnet sheet can be trimmed with scissors to fit odd openings, which makes them more adaptable than rigid plastic covers. They only hold on ferrous metal vents and are a simple blocker rather than an adjustable damper.

About the Square Magnetic Vent Covers 12" x 12", 2 Pack

These square magnetic vent covers come in a pack of 2, each measuring 12" x 12". They are made of rubber that is thick, lightweight and wear-resistant.

The covers have strong magnets, so they snap onto compatible vents and stay in place. They block cold air, improve insulation, reduce noise between rooms and help prevent air leakage from the vent.

Installation only requires attaching the cover to the vent magnetically. The covers can be cut to match your decor. They are easy to remove and clean. They can be used on floor, ceiling and wall vents, air conditioning and HVAC vents, furnace vents, and in basements, cars and RVs.

Questions and answers

Will these stick to my vent?
Only if the vent frame is steel or another magnetic metal. Aluminum and plastic registers won't hold them.
Can I cut them to fit a smaller vent?
Yes. The rubber magnet sheet can be trimmed with scissors to match the opening.
Do they block airflow completely?
They cover the register face to stop airflow. There is no partial setting, so it's fully covered or removed.
Can they be used on ceiling and wall vents?
Yes, the magnets hold on horizontal and vertical steel registers, including floor, wall and ceiling vents.
How do I clean them?
Wipe with a damp cloth or rinse and dry. They lift off the vent for cleaning.
Are they safe around a furnace or HVAC system?
Covering a supply register reduces flow to that room. Keep enough vents open so the system isn't restricted.
