Equipment mounting racks and cabinets

An equipment mounting rack comprising in combination:

• a seismically sound skeleton structure having spaced vertical uprights;
• each of said vertical uprights having an elongate upright partial enclosure having a main section extending in parallel to a main section of that vertical upright, a first lateral section extending from said main section in a spaced relationship to a first side of that vertical upright and having a first extension engaging said first side of that vertical upright, and an opposite second lateral section extending from said main section in a spaced relationship to an opposite second side of that vertical upright and having a second extension engaging said second side of that vertical upright;
• and
• distinct spaced equipment mounting structures attached to each elongate partial upright enclosure of said vertical uprights and constituting side wall structures of a mounting rack interior space;
• wherein said elongate partial enclosure has a substantially C-shaped cross section having said vertical upright between inwardly turned ends of said C-shaped cross-section.
