The PJU14126F is a flange-mounted Type 4X polyester junction box in the nominal 14 x 12 x 6 in size, with a solid lift-off cover fastened by screws. It is built for instrument enclosures, electric, hydraulic or pneumatic control housings, electrical junction boxes and terminal wiring, particularly where equipment may be hosed down or be very wet, and in hot or highly corrosive environments.

The box and cover are compression molded fiberglass reinforced polyester in gray, with enhanced UV inhibitors to resist outdoor weathering. The material is easily punched, cut or drilled on site. Four stainless steel captive cover screws seat in #10-32 brass inserts with retaining O-rings, compressing a captive, oil resistant closed cell neoprene gasket.
