An electrical ground bus bar is fastened to a structural column or wall using insulated spacers with lock washers and nuts. The copper ground bus bar features pre-drilled holes for 5/8-inch mounting bolts. Spacers maintain clearance from the building structure to isolate the grounding system. Dimensional spacing is provided for standard 18-inch and 48-inch long ground bus configurations.
