Items in the card rack family (also known as sub-racks) are enclosure-like products designed to established dimensional standards that provide a mechanical means of assembling large, complex systems in a modular fashion. They provide a means by which multiple circuit boards or similar equipment components can be assembled together in a modular form, which can subsequently be mounted together with other such modularized equipment in a similar, larger enclosure known as a rack.
