Abstract An enclosure including a housing open at the bottom and arranged to conceal pad mounted equipment such as electrical equipment. The housing has one or more doors for access to the interior and includes at least one lateral rib in its walls for reinforcement. The housing is formed integrally from two molded joined sections and has a bottom inturned flange that reinforces the housing and also is used to secure the housing on a ground supported pad. The door is provided with an inturned peripheral flange and the housing around the door opening is formed with a semi-circular or U-shaped guard flange receiving the inturned flange on the door to provide a tamper-proof joint around the door.
