Abstract
A suspended ceiling system employs an array of stringers suspended from an overhead building support. Ceiling panels are positioned by the stringers and each panel interlocks with a plurality of stringers so that it resists upward or downward displacement relative to the stringers. If the system employs rectangular panels, they are attached to the stringers from above. If it utilizes linear wooden panels, they are attached to the stringers from below.
