Abstract
Abstract A louvred handle assembly for equipment racks of the removable type in which louvred elements of the handle assembly cooperate with elongated slots provided in the panel of the equipment rack to permit the flow of air therethrough, especially for cooling purposes, while at the same time preventing ingress of rain or moisture due to the orientation of the louvres and also to prevent ingress of any foreign matter such as stones or small debris. The handle itself may serve as a radiation means to conduct heat away from the equipment rack and into the atmosphere.
