The black Pelican Hardigg BB0030 BlackBox 3U Rack Mount Case is a basic, no-frills, double-ender case designed for applications up to 100 lbs of equipment with a typical fragility rating of 40-80 G. It is a lightweight and compact roto-molded polyethylene case with shock-mounts that provide 2” of sway space to isolate the equipment. There is a 24" rugged, steel, rack frame with M6 threads designed to meet ANSI/EIA 310 standards. The rack is engineered to provide a secure and mobile electronics enclosure. There is a molded-in rib design that provides secure stacking and interlock. Four wide-design, comfort-grip handles and two built-in wheels allow easy transportation.
