O-Z/Gedney™ Class 650 Type IG aluminum junction boxes can be used to house instruments, controllers or control stations, and can also be used as junction boxes or terminal boxes. IG gasketed enclosures have sufficient wall thickness to permit almost unrestricted conduit drilling on all sides, and allow full utilization of inside space at a minimum cost. They may be ordered as either NEMA 4 or NEMA 9.
