Hammond RM4U1908VBK 4U 19" Rack Mount Enclosure, 8" Deep, Vented

The Hammond RM4U1908VBK 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 8.00 in (203 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.

Vented top and bottom panels with Ø4.32 mm [0.170 in] holes over a 373.06 mm x 55.56 mm [14.688 in x 2.188 in] area add airflow to a tall, shallow 4U case only 8.00 in deep.

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 drawing specifies a Type 6063 extruded aluminum frame and .064" 5052-H32 aluminum panels. 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.

Per the RM4U1908VBK drawing, the assembly hardware comprises: 2 Mounting Brackets - .125" Aluminum; 12 Screws - Flat Head 4-40 x 3/8"; 8 Screws - Counter Sunk Head 6-32 x 3/8"; 4 Screws - Counter Sunk Head 10-32 x 3/8"; 12 Nuts - #4 Speed Nuts; Four Self Adhesive Rubber Feet - 1421T3. It accepts pull handle part number 1427P1BK, sold separately.

The RM4U1908VBK is RoHS and REACH compliant, manufactured in North America, and ships in a box at 6 lbs (2.72 kg). Enclosures can be factory modified with milling, drilling or printing, and solid models are available in STEP or IGES for design work.
