Hinged Boxes & Enclosures

Hinged electrical enclosures and outdoor electrical and junction boxes are NEMA rated for weatherproof and waterproof protection. Designed for indoor or outdoor electrical applications, a hinged cover provides easy access to the internal components of the box. Material options include plastic (ABS or polycarbonate) and metal (steel or stainless steel).  Plastic electrical enclosures are lightweight, durable, and naturally corrosion-resistant, making them an ideal choice for many applications. Hinged metal boxes are sturdy and rugged, providing excellent protection for electrical or electronic devices. Metal or plastic electrical boxes with a hinged cover are the perfect solution for many industries. Industries like telecommunications, alternative energy, agriculture, and oil & gas all turn to Polycase for hinged electrical enclosure solutions. Our hinged NEMA enclosures have optional pole mount kits or DIN rail electrical enclosure kits available.

When should you consider a hinged enclosure for your application — and what makes Polycase’s hinged enclosures the best choice? Explore hinged enclosure options below.

Why Use a Hinged Electrical Enclosure?

Using an electrical enclosure with a hinged door panel provides convenient access to the components inside an enclosure without compromising security and protection. These enclosures typically use a hinged front panel that opens via a set of latches or, in some cases, a keyed lock. Models without a built-in lock include a padlock hasp so the user can attach their own padlock for security.

Outdoor hinged enclosures can also have watertight and dust tight IP and NEMA ratings. Through the use of sturdy materials like polycarbonate and stainless steel, plus a silicone gasket, these enclosures maintain strong protection from environmental hazards. They can be an excellent option for heavy-duty outdoor applications that require both robust protection and easy access to electrical components.

Applications for hinged enclosure boxes vary widely — from industrial control panels to outdoor WiFi routers to security systems. Essentially, any application that requires a combination of security, protection, and convenient access can be a strong candidate for a hinged enclosure.

Choosing a Hinged Electrical Enclosure from Polycase

Polycase’s wide selection of hinged electrical enclosures includes options for every need. Our lineup of outdoor hinged enclosures offers models with highly protective NEMA 4X performance ratings, fiberglass reinforced polycarbonate enclosure bases, built-in wall mounting hardware, and much more.

We also offer fast and easy customization options on most of our hinged enclosure models. Our in-house customization services provide a one-stop shop for adding knockouts, threaded holes, connector pass-throughs and more — just use our Instant Quote tool to get started. If your enclosure needs features such as cable pass-throughs and vents, don’t forget to also check our range of cable glands and other enclosure accessories.

Our full lineup of hinged enclosures is here for you to browse and compare. For more options to make enclosure access easier and more convenient, see our collection of clear cover enclosures.
