Some of the ideal environments for this NEMA cabinet are petrochemical facilities, water treatment and sewage plants, even marine applications where seawater, salty air, and windswept sand can damage your sensitive electronics.

Built to NEMA Type 3, 3R, 4, 4X and 12 guidelines, the corrosion-resistant enclosure features a foam-in-place gasket and a latching door that provide an excellent seal against liquid and dirt.

The cabinet's removable three-point door features a hidden hinge and has a vertical stiffener and latch that hold it in place during servicing. The door comes with a screwdriver-slot latch, but you can choose to use the optional Padlocking L-Handle.

You can also order a Mounting Panel for surface mounting equipment on the rear of the enclosure. For installing 19" equipment, use zinc-plated, 14-gauge steel rack angles.
