Outdoor Junction Boxes

Outdoor electrical junction boxes are designed to keep sensitive electrical connections protected and secure in any environment, even underground. Meeting a variety of NEMA and IP ratings ensures our waterproof junction boxes are robust and durable for outdoor use, but they can also be used for indoor applications. Outdoor junction boxes come in a variety of styles including options with hinged covers or knockouts, and options that can be wall mounted or pole mounted. With plastic, aluminum, and steel options available in a variety of sizes, it's easy to find the perfect electrical junction box solution. Read our guide on junction box types.
