The Proline G2 industrial modular enclosure is designed to be strong, fast and easy to use. The frame provides strong protection under load in every dimension and under torque. This allows the frame to remain square under load, keeping side and rear covers aligned and eliminating door-closing issues. The EZ-Load mounting system is designed to make the process of loading mounting subpanels into the frame faster and safer by providing a variety of loading options. EZ-Load glide blocks can be used to load a subpanel vertically from the front, rear and side or horizontally from the front or rear.
