Return Air Grilles

Steel return air grilles and return air filter grilles in every standard size, from 6x6 up to full commercial dimensions. Shop TRUaire, Hart & Cooley, Tuttle & Bailey and more — every listing shows the exact duct-opening size, material and fin spacing, with the manufacturer spec sheet attached.

Need filtration at the return? A filter grille holds a standard 1-inch filter behind a hinged face, so you can swap filters without opening the duct. Measure your duct opening (not the old grille's outer face) and order that size.
