ABSTRACT:
A cabinet for air handling equipment includes two similarly sized covers that are each nonsymmetrical about their vertical centerline. Each cover has an original supply or return air duct opening plus space for an alternate opening. The original and alternate openings are of different shapes to accommodate round or rectangular ducts. The two covers can be interchanged with each other and inverted to provide various supply and return air duct configurations.
