A rack for electrical equipment is constructed for resistance to failure in earthquake conditions. The rack has a base and two legs extending upwardly from the base. A cross member spans between and interconnects the legs near their tops. A reinforcing strut on either the front or back flange of each leg forms, in combination with the flange a box beam element which greatly strengthens the flange of the leg. A brace attached to the underside of the cross member passes through an opening in the web of the leg and is rigidly attached to the reinforcing strut. The arrangement of the brace facilitates the mounting of EMI shielding on the rack. The rack also has a one-piece cover for closing the base of the rack.
