When you need to see an instrument or indicator without opening the box, the PJ664RHW adds a bonded polycarbonate viewing window to a raised, hinged cover. The Type 4X fiberglass reinforced polyester enclosure measures 6.10 x 6.10 x 4.18 in (155 x 155 x 106 mm) and serves as an instrument enclosure, junction box, terminal wiring enclosure or control housing in wet, washdown, high-temperature or highly corrosive environments.

Box and cover are compression molded fiberglass reinforced polyester with a gray finish and enhanced UV inhibitors against outdoor weathering; the window is polycarbonate. The material is easily punched, cut or drilled. The cover swings on a stainless steel hinge, continuous per the series, and is closed with two stainless steel captive cover screws with retaining O-rings in #10-32 brass inserts. A closed cell neoprene gasket seals the cover.

• Panel materials: white powder coated steel, unfinished aluminum or fiberglass
• Four stainless steel mounting feet on rear brass inserts
