Control the flow of air through your home or RV with our Magnetic Vent Covers. These 3 flexible magnetic sheets install quickly and securely to metal sidewall and floor vents. Sized to fit standard vents, at 5” by 12”, and may be trimmed down with scissors for a more custom fit. By closing off the vents in one area, you redirect the air flow to needed areas. These white covers may be painted or papered to match your decor. Note: Do not cover too many registers at once. Do not use on return air registers. These vent covers do not have adequate strength to stay adhered to ceiling vents and are not intended for that use. Deflecto was founded on innovative, problem solving products. For over a half century, we have built a tradition of discovering and meeting needs with invention and dependable manufacturing. Today, Deflecto is the world’s largest chair mat, bicycle reflector and dryer venting manufacturer and a global leader in sign and literature holders, office workspace accessories and other air distribution products.
