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.
