600x200 shooting grid

Molded return air grilles of the GSA series, are designed to be placed inside buildings for air return or recirculation, for small flow rates. They are also suitable for application to panels of low thickness, as the grilles have no part to be recessed. Their conformation also allows them to be used outdoors as long as they are not directly exposed to the weather. They can be installed on both walls and ceilings.
