Single & Double Door NEMA 3R Cabinets

ETM Manufacturing’s NEMA 3R Enclosures are specifically designed for “either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure.”  UL50 certification is available on some designs.

We can customize our NEMA 3R Boxes to meet your specific height, width, length, color, and backpanel type needs. Available in aluminum, powder-coated steel or stainless steel.  Able to configure with single or double doors, our enclosures are built to last:
