Rectorseal 358X20 Brown Floor Return Air Grille 8x20

Product Description

The RECTORSEAL 358X20 is a stamped steel floor return air grille designed for residential HVAC systems requiring dependable airflow intake at floor level. Part of the TRUaire 35 Series, it features a fixed stamped face that delivers consistent return air performance without adjustable louvers. The 8-inch by 20-inch face dimension fits standard rectangular floor duct openings in residential construction. A brown powder-coat finish provides corrosion resistance and blends with common flooring materials. Licensed HVAC technicians and general contractors install this grille as part of a ducted forced-air return system.

This grille is suited for residential forced-air HVAC installations where a floor-mounted return air opening measures 8 inches by 20 inches. The fixed-face stamped steel construction makes it appropriate for medium-size rectangular floor boots in single-family homes, condominiums, and light commercial spaces with standard floor duct layouts. The brown finish is a common selection where the grille must coordinate with wood or laminate flooring.
