Arlington non-metallic rainbox is the raintight, labor-saving solution to installing a fan or fixture exposed to the elements, inside or outside. This box eliminates the need for time consuming field modifications. It's completely sealed so water stays out and wiring stays dry. Plus, it supports a 70 lb fan or fixture securely and safely. Rainbox is perfect for any area with open exposure to wind-driven rain and water spray, anywhere you would install a wet or damp rated fan. Uses include pool screen enclosures, open porches, lanais, outdoor kitchens and eating areas, pavilions, greenhouses, barns and more.
