The PCJ16148L is a Type 4X polycarbonate junction box with a solid light gray polycarbonate cover, sized at a 16 x 14 in face and 8 in nominal depth. It is built to insulate and protect controls and components indoors or outdoors, for pump controls, waste water, irrigation, solar/wind and chemical plants.

The box and cover are injection moulded polycarbonate thermoplastic that is easily punched, cut or drilled, with enhanced UV inhibitors against outdoor weathering (UV rating f1 per UL746C). The cover closes with two 316 stainless steel lockable snap latches, and the snap latches include a provision for padlocking. The matching polycarbonate cover is solid, with the light gray finish of the polycarbonate material. A captive, oil resistant FIP polyurethane gasket provides a positive seal. The molded hinge uses four snap-in polycarbonate hinge knuckles. Wall thickness is .19 in (4.8 mm).

Nominal size is 16 in x 14 in x 8 in (406 mm x 356 mm x 203 mm); the enclosure measures 15.98 in (406 mm) high, 13.98 in (355 mm) wide and 7.81 in (198 mm) deep, with a shipping weight of 8 lbs (3.63 kg). Threaded #10-32 brass inserts are provided for mounting the optional 14R1513 inner panel, which measures 14.75 in (375 mm) by 12.88 in (327 mm). The drawing lists optional back panel thicknesses of 0.100 in (2.54 mm) aluminum, 0.075 in (1.91 mm) white steel or 0.188 in (4.78 mm) PVC.
