The PJU664LW is a 6 x 6 x 4 Type 4X fiberglass polyester junction box from the PJU Series with a bonded polycarbonate viewing window in a hinged snap latch cover and mounting feet. The viewing window allows the interior to be seen with the cover closed. Typical uses are instrument enclosures, electric, hydraulic or pneumatic control housings, electrical junction boxes and terminal wiring enclosures, including locations that are hosed down, very wet, hot or highly corrosive.

The box and matching cover are compression molded fiberglass reinforced polyester in a light gray finish, with enhanced UV inhibitors for outdoor weathering, and are easily punched, cut or drilled. This version uses a hinged cover on a continuous stainless steel hinge pin that closes with a stainless steel lockable snap latch located on center. A captive oil resistant closed cell neoprene gasket provides a positive seal.
