The PJU1084HW is a 10 x 8 x 4 in Type 4X junction box molded from fiberglass reinforced polyester, fitted with a clear polycarbonate hinged screw cover and four mounting feet. It is designed for use as an instrument enclosure, control housing, junction box or terminal wiring enclosure, and the clear cover shows the interior without opening the box. This version pairs the hinged screw cover with rear mounting feet; the flanged equivalent is the PJU1084HWF.

This is a shallow 4.13 in deep body on a 10.05 x 8.27 in face. The enclosure measures 10.05 in (255 mm) high, 8.27 in (210 mm) wide and 4.13 in (105 mm) deep (nominal 10 x 8 x 4 in), with a 0.13 in (3.30 mm) wall. Brass inserts accept the optional 8.75 in (222 mm) x 6.88 in (175 mm) inner panel 14R0907. Shipping weight is 5 lbs (2.27 kg).

The clear window cover swings on a continuous stainless steel hinge pin and is secured by two stainless steel captive cover screws with retaining O-rings into #10-32 brass inserts. A closed cell neoprene gasket seals the cover, and the box and cover material is easily punched, cut or drilled. The light gray material has enhanced UV inhibitors, operates from -40°C to 130°C (-40°F to 266°F) and has an impact index of 6.78 J (5 ft/lb).

Four polycarbonate mounting feet attach to the rear through #10-32 brass inserts and stainless steel screws; with the feet fitted the drawing shows an overall height of 11.47 in (291.28 mm), mounting spacing of 10.75 in (273.04 mm) and (4) 0.31 in (7.95 mm) holes. Mounting hardware is included.
