Arlington non-metallic 21.8 cu-in multi-purpose box is the labor saving solution to installing a fan, light fixture or security camera that's exposed to the elements - inside or outside. This MULTI PURPOSE BOX eliminates the need for time consuming field modifications. It's completely sealed so water stays out and wiring stays dry when used with gasketed accessories. It supports up to a 70 lb fan or fixture securely and safely in a damp or dry location. Perfect for any area with open exposure to wind-driven rain and water spray, it's useable anywhere you would install a gasketed wet or damp rated floodlight or accessory. Uses include pool screen enclosures, open porches, lanais, outdoor kitchens and eating areas, pavilions and more.
