Corrosion resistant fiberglass enclosures are suited for use indoors or outdoors where corrosion may be a problem, to protect the enclosed equipment from water coming from any direction, dust, dirt and oil. The 5412 ESFR series are made of SMC polyester fiberglass composite, aesthetically designed and produced exclusively by EXM. The hinges can be placed on any side of the enclosure and permit right, left, top or bottom door opening. The mounting feet can be installed at 0 or 90°, to be used either at the top and bottom of the box or at its sides.
