Universal deep-hinged doors offer a viewing window for clear visibility and are ideal for protecting HMI and keypad operator devices while allowing monitoring of these devices. These doors with polycarbonate windows are available in various sizes to fit compatible Hubbell-Wiegmann NEMA 3R, 4, 4X or 12 rated enclosures. The viewing windows allow the operator to monitor the devices while the door is latched shut, keeping them protected during operation. The doors have quarter-turn style latching for easy access, concealed hinges with removable pins, and are fabricated from 14-gauge carbon steel with a light-textured gray finish or 14-gauge polished 304 stainless steel. A drill template and mounting hardware is provided, and poured-in-place gaskets seal both the door and the mounting surface. Universal deep-hinged window doors start at $358.00.
