ABSTRACT:
An air guard assembly used to direct air forced through an overhead air diffuser toward the floor of a building. The assembly has a plurality of elongated linear baffles. Each baffle has a strip of magnetic material that adheres directly to metal ceiling structures to surround and enclose the diffuser within the assembly. A gripping tool having an elongated handle is used to locate the baffle adjacent the metal ceiling surface and remove the baffle therefrom. The baffle has a pair of grooves preventing the gripping tool from slipping off the baffle.
