This diagram establishes the maximum spacing requirements for suspended ceiling seismic bracing. It specifies a four-way, forty-five-degree diagonal wire bracing system paired with a compression strut at designated intervals. Vertical hanger wires are required at each carrying channel. A stabilizer bar is installed specifically at the unattached wall line. The layout defines a maximum distance of four feet to the first bracing point from the wall, with additional six-inch maximum offsets for perimeter conditions. Locations must be coordinated with mechanical systems to ensure compliance with seismic bracing requirements.
