In summary, there are 4 main components that make up a complete Heavy-Duty Rectangular system. The Housing enclosure that is stationary and typically mounted to the machinery or panel equipment. The Hood enclosure connection that would typically be at the end of a cable and would be used with a Cable Gland. The Inserts, where the customer would terminate the conductor wires to the mating contacts. Finally, the Cable Gland assembly where the cable will enter the hood or housing enclosure and terminate to the Insert. Together, these components provide a reliable connection point for the most critical environments and applications.
