The 1590R is the largest size listed in the 1590-RIBBED diecast aluminum series table, with room for P.C. boards up to 182.42 mm by 102.42 mm. It suits OEM engineers, integrators and facilities teams housing larger control or instrument electronics in a rugged metal enclosure with internal ribs that guide the board.

The box and lid are diecast aluminum alloy, tough yet easy to machine. This natural version is unpainted and vibra finished for a smooth surface with no sharp edges. Lap joint construction protects against access of dust and splashing water, and the standard 1590R is rated IP54. Unlike the smaller sizes, the purchased assembly includes box, lid and 6 cover screws (M3.5x0.6), threaded into factory-tapped holes, with a recommended torque of 50-55 cN.m [71-78 ozf.in], or 25-30 cN.m [36-43 ozf.in] with a gasket.

The part page lists 7.55 in x 4.37 in x 2.24 in (192 mm x 111 mm x 57 mm); the series table lists 192 x 102 x 61 mm, and the drawing outline is 191.80 x 111.60 x 61.00 mm.
