deflecto® Magnetic Vent Covers, 8 x 15 x 0.12, White, 3/Pack

Help reduce your home's energy costs. These reusable, magnetic vent covers let you close off air registers in rooms you aren't using, restricting the flow of forced air from heating and cooling systems, so the air is only directed to the areas you choose. These magnetic vent covers may only take a few minutes to install, but the savings will continue to roll in month-by-month. Perfect for metal air registers without dampers. Can be used on metal floor, wall or ceiling registers. Magnetic sheets can be cut down to size easily with household scissors, and can be painted or papered to match your room decor.
