Certain embodiments of the present invention provide an apparatus for closing off an opening above, below, or between electronic equipment in a rack. The rack includes a pair of equipment rails. The electronic equipment is mounted to the equipment rails. The apparatus includes a base, a roller shade, and a handle. The roller shade is rotatably connected to the base and includes a free end extending from the base when the roller shade is rotated. The handle is connected to the free end of the roller shade. The base is removably connected to the equipment rails at a first position. The handle is removably connected to the equipment rails at a second position spaced apart from the first position such that the free end of the roller shade is extended to close off the opening in the rack.
