Abstract: An air deflector is disclosed with adjustable brackets for suspending the deflecting shield at variable distances from an air vent positioned within a dropped ceiling. The suspension brackets include a hook for resilient flexible securement with respect to the inverted T-shaped support members of the dropped ceiling as well as a rod having a number of cross members positioned thereon extendable through slots defined in the air deflector for maintaining that deflector at variable distances from the vent defined in the dropped ceiling thereabove. A vane member is included which may be engageable with respect to another similarly configured vane member such as to be angularly oriented with respect to the upper surface of the deflecting shield to guide air outwardly therefrom away from wall or corner areas as desired. For this purpose grooves may be defined in the upper surface of the deflecting shield.
