A structural support frame for electrical equipment is mounted onto a concrete roof slab using two-inch diameter galvanized steel pipe framing. The frame is welded to four-inch by eight-inch by three-eighths-inch galvanized steel base plates secured with two three-eighths-inch expansion anchors each. A conduit sleeve penetrates the roof assembly alongside the frame, sealed with a pipe sleeve flashing. The support stands with a minimum eight-inch clearance above the roof surface and a one-foot-six-inch upper section spacing.
