An enhanced strength grade level utility enclosure comprises a vertical wall structure having an upright inner wall panel (46) extending from an upper edge to a bottom edge of the structure. The inner wall panel (46) has an inside face spanning the enclosure's interior. One or more narrow, vertically extending slotted regions (58) are recessed in the inside face of the wall panel. Upright rigid support bars (60), optionally adapted for use as cable racks, are positioned in and rigidly affixed to separate slotted regions on the wall panel. The support bars (60) provide a continuous means of rigid vertical support from the upper edge down to the bottom edge of the enclosure's wall structure. The recessed support bars, in combination with the vertical wall structure, provide enhanced wall strength in excess of industrial vertical side wall and center load test standards. |
