Abstract: An improved network housing device for protecting telecommunications and electrical systems disposed in the outdoors from foreign objects and influences of the weather and atmosphere comprises a dual enclosure device having an outer enclosure and an inner enclosure unit. With this dual structure, requirements imposed by outdoor use can be allocated among the outer and inner units, with the outer unit fulfilling weatherability and ultra-violet stability requirements, and the inner unit fulfilling low-flammability requirements. The device may be fabricated entirely with plastic to provide a reliable and low-cost housing.
