The 5100 ES are used where the control installation does not demand a high degree of protection (such as watertight or dust tight), but where a quality enclosure is warranted. The 5100 ES are made from quality 14 GA or 16 GA steel, with corner seems 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. These enclosures feature die cast hinges, which are bound to the cover by an exclusive one piece concealed hinge. the cover can be removed by unfastening the antivibration lock screws. A ¼ turn locking mechanism ensures positive closing. Internal mounting holes are provided. Each enclosure comes complete with a 12 GA inner panel which is double bent* for maximum rigidity and which mounts on M8 welded studs. Enclosures and panels are finished with heat fused powder paint, electrostatically applied on a pretreated base. Box is ANSI/ASA 61 gray, panel is white (other colors available).
