The RIB series from Functional Devices is a prefabricated, 3-in-1 enclosure package that is fitted with a power supply and sub-panel right out of the box. The series offers two enclosure choices, two power supply choices, and three sub-panel choices. Enclosures come in narrow or wide styles, each made with 14-gauge steel. Both have a reversible door so users can access the panel from whichever direction fits best. A key latch is included to lock the panel from unauthorized personnel.
