RETURN GRILLE J1,,, ingle Fixed Deflection Introduction:,,, The / return grilles are designed to fit most common commercial and residential applications. They offer fixed 3/4 blade spacing with 3 deflection and a 1 1/4 flange. The / return grilles are designed to fit most applications where limited sight through the grille is required. They offer fixed 1/2 blade spacing with 3 deflection and a 1 1/4 flange. If the application requires large amounts of air to be returned through the return grille, then the blade deflection of should be used to keep the pressure drop and sound to a minimum.
