ABSTRACT:
A novel and improved cover assembly for an air moving device such as a fan or air conditioner mounted in a wall or ceiling for drawing air therethrough. To prevent cold air from leaking through the device, the improved cover assembly is detachably connected by magnetic means to the rim of the device. The cover assembly is made of insulating material and has a plurality of recesses or channels formed on the internal side thereof extending in spaced relation to each other from the outer edge of each of the inner recesses so that a wide range of rims can be served by one size cover assembly. Depending on the rim size or shape (rectangular, square or circular) the cover assembly can be "fitted" to any rim in question by removing the excess material at the appropriate line of perforations.
