The PCJ12104F is a Type 4X polycarbonate junction box from the PCJ Series with a lift-off screw cover in solid light gray polycarbonate. It is a 12 x 10 x 4 in nominal enclosure measuring 11.92 x 10.15 x 3.98 in, the shallower of the two depths offered in the 12 x 10 footprint. The series is designed to insulate and protect controls and components in both indoor and outdoor conditions, and is aimed at industrial pump controls, waste water, irrigation control, solar/wind and chemical plant applications.

The body and matching solid cover are injection moulded polycarbonate thermoplastic in a light gray finish that is easily punched, cut or drilled. The lift-off cover is fixed with 4 stainless steel screws; the drawing calls out (4) #10-32 brass inserts and 316 stainless steel captive cover screws with retaining O-ring and a fip (formed-in-place) polyurethane gasket. Enhanced UV inhibitors protect against outdoor weathering, and the series lists an impact index of 16 J (12 ft/lb) and operating temperatures from 130°C down to -35°C (266°F to -31°F).

For surface mounting, this version is fitted with 2 glued-on polycarbonate flanges with 0.34 in (8.65 mm) mounting holes. If you prefer mounting feet, the equivalent is PCJ12104. Threaded brass inserts are provided for optional inner panel or terminal kit mounting, and mounting hardware is included. The PCJR1109 optional inner panel for this size measures 10.75 x 8.88 in.
