This Rectangular vent cover from Elima-Draft prevents the loss of heat through your wall and ceiling registers/vents. It attaches itself to your vent with magnets which are discreetly located on the bottom - thus, this product can only be used with aluminum or steel vents. Rectangular vents are more common in the Midwest. If you have a square vent/register, check out all of our Elima-Draft magnetic vent and register covers
for wall vents or ceiling vents.
This vent cover will fit 4 sizes of rectangular vents: 14" x 8", 14 x 6", 12" x 8" and 12" x 6".
