ABSTRACT:
An air distribution device system includes an air distribution device of rectangular configuration and an auxiliary frame adapted to flush-mount the air distribution device within a ceiling of the type wherein ceiling material is directly fastened to overlying structural members such as joists or rafters. The auxiliary frame is substantially rectangular in form and is fashioned from elongate frame members of T-shaped cross section. The vertical portions of the T-shaped frame members are fastened to the structural members so that the horizontal portions of the frame members are substantially coplanar with the ceiling. Thereafter, the air distribution device rests upon, and is supported by, the horizontal portions of the frame members. When desired, the air distribution device can be raised off the auxiliary frame to obtain access to the interior of the ceiling.
