Innovations in manufacturing have made possible these extra-large plastic enclosures. Gasketed for use in harsh locations, they meet NEMA 1, 2, 4, 4x and IEC 529-IP66 requirements. This high level of protection makes them useful in wet, dirty and/or corrosive environments. They are UL listed for Type 4 and 4x. Covers latch securely. Versions with transparent covers are available. Plastic enclosures, unlike enclosures made of metal, are suitable for outdoor RF signal and IoT applications.
