The 1591REBK is the largest enclosure in the 1591R line: a 190 x 111 x 61 mm black ABS case whose interior is sprayed with an EMI/RFI copper conductive coating. It gives OEM engineers and electronics builders a shielded housing with room for long printed circuit boards mounted vertically in the molded-in card guides.

Each enclosure part is molded from flame retardant ABS plastic, a material carrying a UL flammability rating of 94V-0, in a smooth black finish with black screws. The interior of each part is specially masked and sprayed with an RFI/EMI copper conductive coating, and the coating manufacturer specifies an attenuation of more than 75 dB from 1 MHz to 1 GHz. The enclosure is designed to meet IP54 and is listed as RoHS and REACH compliant.

The nominal size is 190 x 111 x 61 mm, and the drawing gives overall dimensions of 190.40 x 110.60 x 60.80 mm. With an inside length of 183.52 mm and inside height of 56.60 mm, it suits longer boards that need shielding. Internal side walls include molded-in card guides with a guide height of 51.60 mm and a slot width of 2.06 mm, making the case well suited to vertical mounting of printed circuit boards.

The purchased assembly includes the box, lid, 6 cover screws and pre-installed brass inserts. The lid is secured with M3 x 10 mm Phillips machine screws threaded into integral brass bushings, which suits applications where repetitive assembly and disassembly are required; recommended torque is 35.5-42.5 ozf.in (25-30 cN.m). The matching plastic flange kit for the 1591REBK is 1591FEBK. Some chemicals can damage or weaken plastic, so check the manufacturer's chemical resistance guidance before using solvents, thread lockers or cutting fluids.
