Deflect-O Jordan 12 in. H X 5 in. W 1-Way White ABS Plastic Register Cover

Save energy with 5" x 12" magnetic vent covers that let you close off air registers in rooms you aren't using. Deflecto magnetic air vent covers restrict the flow of forced air from heating and cooling systems, so the air is only directed to the areas you choose. Perfect for metal air resgisters without dampers. Can be used for floor, wall or ceiling registers. Metallic sheets can be cut to size easily with household scissors.
