Suspended ceiling wire attachments anchored to a structural concrete ceiling comprise two conditions: a vertical hanger wire and a splayed bracing wire. The vertical hanger wire clip attachment utilizes a twelve-gauge by three-quarter-inch wide ceiling clip secured to the concrete with a shot-in anchor requiring three-quarter-inch minimum penetration, or an approved drilled-in anchor. The vertical wire features three tight turns in one and one-half inches. The splayed bracing wire clip attachment is anchored with a five-sixteenth-inch diameter minimum drill-in expansion anchor securing a one-inch wide by twelve-gauge minimum steel strap bent to align with the wire. The bracing wire is oriented at a maximum angle of forty-five degrees and features four tight turns in one and one-half inches, with a maximum five-eighths-inch clearance dimension noted.
