Abstract: A spacer device for separating electronic equipment modules has a plurality of spacing elements held together by a plurality of rigid interconnection rods. The spacer device increases the amount of available storage space in a given area by allowing units to be stacked vertically. The interconnection rods provide a terminal element at each opposing end thereof, each of the terminal elements being adapted for being pressed into an engagement hole in the spacing elements for capture of the interconnection rod therein by a rod capturing chamber of the spacing element. In use, the spacer device is positioned between two electronic equipment modules to improve ventilation around the electronic equipment modules, thereby facilitating the cooling of the electronic equipment modules. The electronic equipment modules may be fastened together with a plurality of inelastic earthquake bracing devices to prevent excessive movement of the electronic equipment modules.
