Rectangular housings refer to a category of industrial enclosures commonly used in electrical and electronic applications, rather than a specific brand. These housings are typically produced by various manufacturers globally, including companies like Hammond Manufacturing (Canada), Rittal (Germany), and Bud Industries (USA). They serve industries such as automation, telecommunications, and energy, providing protection for sensitive components. Key products include junction boxes, control cabinets, and modular enclosures designed for durability and environmental resistance. Companies like Grainger and Radwell often distribute these housings as part of their industrial supply offerings.
