About this detail

A seismic separation joint for suspended acoustic ceilings with continuous ceiling areas exceeding two thousand five hundred square feet comprises exposed ceiling tees field-cut to length and connected with continuous wall mouldings secured by steel pop rivets at each runner. A one-inch clear gap is maintained at the joint, with wall-mounted splices created by clipping the horizontal leg, lapping the vertical leg, and installing three number eight sheet metal screws. Twelve-gauge hanger wires are anchored to the structure above, with perimeter wires spaced a maximum of eight inches from the support.
