Model SX Vent Cap

The SXL Return Air Grille is a large version of the SX. Its main application is as a return air grille, though it can serve in the same purpose as the SX. Its flush face lends a clean look, and its aluminum construction and spring clip mounting makes it easy to install with no screws to mar the surface. Insect screens are an option.

No louver manufacturer warrants their louver to prevent water penetration under all possible circumstances of wind and rain.
