Non-Metallic NEMA 4X - Slim Line Junction Box Enclosures
(Fiberglass Industrial Cabinets)

NEMA 4X enclosures are typically made of stainless steel or plastic. These NEMA enclosures are used in harsher environments than standard NEMA 4 units. Applications where corrosive materials and caustic cleaners are used necessitate the use of a NEMA 4X enclosure. Applications include food, such as meat/ poultry processing facilities, where total washdown with disinfectants occur repeatedly and petro-chemical facilities, including offshore petroleum sites. NEMA 4X is used when protection from the worst environments is required.
