Looking to replace those rusted and tarnished old register vent covers? We carry a wide variety of modern grilles and louvers at great prices.

Note - Registers are measured by the opening they are meant to cover. For instance, if you have a ceiling opening that measures 8-1/4" x 8-1/4" you would order an 8x8 register. The back part of the register will be undersized to fit about 7-5/8" x 7-5/8". The face of the register will cover up to 9-1/2" x 9-1/2".
Stamped Face Return Air Grille - No Filter
Standard style return air grille. Steel construction. Vanes are fixed.
Use to cover air transfer openings where no filters are needed.
