The RM5U1922VBK is the 22.00 in (559 mm) deep, vented-top/bottom 5U model of the RM rack-mount aluminum instrument enclosure. It stands 8.75 in (222 mm) high and 16.60 in (422 mm) wide, and its perforated top and bottom panels suit deep builds that produce heat, such as amplifiers, power conversion or computing hardware in a 19 in rack or on a desk.

The all-aluminum construction uses extruded side panels 0.125 in (3.2 mm) thick, extruded front and rear panels 0.125 in (3.2 mm) thick and flat top and bottom panels 0.064 in (1.6 mm) thick. The finish is a rugged textured black powder coat, so panels are not grounded to the frame; the grounding method is to be determined by the customer.

Overall dimensions are 8.75 in (222 mm) high x 16.60 in (422 mm) wide x 22.00 in (559 mm) deep, occupying 5 rack units. With the included pair of 19 in rack mounting flanges fitted, the drawing shows an overall width of 482.61 mm [19.000 in], with ear holes on 466.10 mm [18.350 in] centres. The front and rear panels measure 415.30 mm [16.350 in] wide by 221.49 mm [8.720 in] high, and handle mounting holes are provided for the 1427P1BK pull handle, available separately. The drawing shows vent holes of Ø4.50 mm [Ø0.177 in] on 7.94 mm [0.313 in] spacing. For rear support in a 4-post rack, the RM5U18BRKT adjustable-depth bracket kit (sold in pairs, up to 16.00 in / 406 mm added depth) is listed for this model.

The knockdown design ships unassembled. Each assembly includes 2 interchangeable front and rear panels, 2 interchangeable top and bottom panels, 2 interchangeable side panels, 4 self-adhesive rubber feet for desktop use, assembly hardware including screws and speed nuts, and 1 pair of 19 in rack mounting flanges with hardware. It is RoHS and REACH compliant and manufactured in North America; it can be factory modified (milling, drilling, printing), and STEP or IGES models are available.
