allG offers PVC NEMA 3R Junction Boxes that are ideal for outdoor use, primarily to provide a degree of protection against falling rain or sleet. They are durable and provide protection in outdoor applications against rain, sleet and snow, or indoors against dripping water. This style of electrical enclosure can be used as a wiring box, junction box, or pull box in commercial and general industrial applications requiring an industrial cabinet or NEMA enclosure. Knockouts are not provided on Junction Boxes. allG also offers a complete Mounting Kit (allG Part #5255-MNT-KIT) for your convenience (sold separately).
