An angle clip pins to the overhead concrete structure and bolts to a vertical zero point zero fifty-five gauge compression strut. The bottom of the strut slots over the ceiling main runner and fastens with a number eight self-tapping screw. Typical twelve-gauge hanger wires suspend the grid at four feet on center. Four twelve-gauge ceiling splay wires extend at forty-five degree angles in perpendicular and parallel pairs relative to the main tees for seismic bracing. Ceiling locking cross tees intersect the main runner at four-foot intervals.
