The 5412 ESB water, oil & dust tight enclosures are used indoors or outdoors in areas where the enclosures may be subject to hosing or to water coming from any direction or for protection against dust, dirt or oil splashing. The 5412 ESB are made from quality 14 GA or 16 GA steel, with corner seams continuously welded. The opening has a curled lip around all sides to prevent dripping water from entering the enclosure when the door is open, it also increases rigidity. A high quality robotically poured-inplace seamless gasket ensures a complete and durable water tight seal. The pins of the concealed hinges can be pulled out to remove the door. A ¼ turn locking mechanism (or 3 point latch system on larger enclosures) ensures positive closing. Internal mounting holes are provided. Each enclosure comes complete with a 12 GA galvanized inner panel which is double bent* for maximum rigidity which mounts on M8 welded studs. Enclosures are finished with heat fused powder paint, electrostatically applied on a pretreated base. Box is RAL7035 textured light gray, panel is unpainted galvanized steel.
