Hammond RM4U1922VBK 4U 19" Rack Mount Enclosure, 22" Deep, Vented

The Hammond RM4U1922VBK is a 4U vented rack-mount / desktop instrument enclosure from the RM Series, measuring 7.00 in (178 mm) high, 16.60 in (422 mm) wide and 22.00 in (559 mm) deep. It is built for OEM engineers, test and measurement designers and integrators who need a lightweight, all-aluminum case that can mount in a standard 19 in rack using the included pair of rack mounting ears, or sit on a desktop.

The vented top and bottom panels use Ø4.50 mm [0.177 in] holes across a 373.06 mm x 127.00 mm [14.688 in x 5.000 in] area, adding airflow to a 22.00 in deep 4U chassis.

Construction uses extruded aluminum side panels and extruded aluminum front and rear panels, each 0.125" (3.2 mm) thick, with flat aluminum top and bottom panels 0.064" (1.6 mm) thick. The enclosure is finished in rugged textured black powder coat and uses a knockdown design that ships unassembled for easy handling and shipping protection. Because of the powder coat, panels are not grounded to the frame; the grounding method is determined by the customer.

Each assembly includes interchangeable front and rear, top and bottom, and side panel pairs, four self-adhesive rubber feet, assembly screws and speed nuts, and a pair of 19" rack mounting flanges with hardware. It accepts pull handle part number 1427P1BK, and the ordering table lists RM4U18BRKT as its adjustable-depth rear mounting bracket, sold in pairs.

The RM4U1922VBK is RoHS and REACH compliant, manufactured in North America, and ships in a box at 13 lbs (5.90 kg). Enclosures can be factory modified with milling, drilling or printing, and solid models are available in STEP or IGES for design work.
