NEMA 4X enclosures are typically used in extreme, harsh, and corrosive environments that exceed the capabilities of Nema 4 enclosures. Nema 4X enclosures are generally manufactured using 304 & 316 stainless steel. Click here to view all NEMA ratings

Enclosure Insulation & Ratings
Q: What is the R rating for Bison Profab’s enclosure insulation?
We manufacturer NEMA 3R enclosures. NEMA 3R enclosures are designed very similar to NEMA 3 enclosures, however 3R enclosures can be ventilated. When ventilated, the degree of protection provided by NEMA 3R enclosures against windblown dust is diminished. Click here for more details on NEMA 3R enclosures.
Q: What do you use to insulate the inside of an electrical enclosure?
Bison ProFab can insulate your enclosure to provide added levels of environmental control and efficiency. Outdoor electrical enclosures can benefit from conventional foam board insulation (typically 3/4" to 1" thick), or if you are low on internal space we also offer Low-E reflective enclosure insulation.
