Abstract
Abstract An enclosure for electrical components and the like is disclosed which protects the components in hazardous environments. The enclosure includes a unitary body having a generally cylindrical cavity and a closure securable to the body for closing the top of the cavity. A land within the cavity supports a first electrical component substantially normal to the axis of the cavity. Two pairs of longitudinal slots are provided for receiving second and third electrical components normal to the first component. A first internally and externally threaded outlet is situated at the bottom of the body substantially axially aligned with the cavity and second and third internally threaded outlets are located on opposite sides of the body generally above the land supporting the first component.
