Abstract
Abstract A vented cap for covering an apparatus housing utilized in an outdoor environment including a pair of spaced apart roof panels defining therebetween a chamber. Apertures in the room panels out of registry with each other provide a path for ventilation of the enclosure while preventing the ingress of environmental elements such as rain. Mesas are raised above the surface of the inner roof panel and each contains one of the inner apertures. Drain apertures are formed around the periphery of the vented cap assist in permitting egress of environmental elements from and ingress of cooling air to the chamber.
