Hinged Electrical Enclosures

Hinged electrical enclosures 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 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 and 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 kits available.

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.
