An annular seal is positioned in an opening of a shelf for supporting electronic equipment. The annular seal has an outer portion which is clamped between an air flow control plate and the shelf to seal the plate to the shelf, and has an inner seal portion of greater height than the outer portion which extends through the opening in the shelf. The inner seal portion extends above the shelf and is sufficiently resilient to seal against the underside of electronic equipment which can be slid into position the shelf.
