The RMCS190513BK1 is a 3U rack-mount aluminum instrument enclosure from the RMC Series, built with solid (unvented) top and bottom panels. Its body measures 17.00 in (432 mm) wide by 13.00 in (330 mm) deep and 5.23 in (133 mm) high, and with the included brackets fitted the drawing shows an overall width of 482.60 mm [19.00 in], so it can go into a 19-inch rack or sit on a bench as a desktop case.

Construction uses type 5052 H32 aluminum for easy modification: 0.125 in (3.2 mm) side panels and rack-mount brackets, 0.064 in (1.6 mm) front and rear panels, and 0.062 in (1.6 mm) top and bottom panels. Assembly is all machine screw and PEM nut, so the case stands up to repeated assembly and disassembly, and any of the six panels comes off by removing only 4 screws. The enclosure is finished in a rugged, satin textured black powder coat.

This 3U enclosure offers 5.25 in (133 mm) of usable mounting height and 4.18 in (106 mm) of inside height clearance with the optional internal chassis panel (RMP1913) installed. Inside, the drawing gives 128.57 mm [5.06 in] of inside height and 425.45 mm [16.75 in] of inside width, with an inside length of 325.92 mm [12.83 in]. Shipping weight is 6.39 lbs (2.90 kg).

The knockdown design ships unassembled for easy handling and shipping protection. The purchased assembly includes 2 front/rear panels, 2 top/bottom panels, 2 side panels, 2 mounting tabs, 4 inner brackets, 24 screws and 4 rubber feet; recommended cover screw torque is 8.9-9.4 lbf-in (100-110 cN-m). Panels are not grounded to the frame because of the powder coat, so the grounding method is determined by the user. The part is RoHS and REACH compliant.
