Generated explanation

The illustration shows a wood roof truss lifting above an interior partition and two alternative remedial details at the ceiling-to-wall junction. Detail A anchors the ceiling drywall edge to a 1x6 installed between trusses, with clips noted as an alternative. The first ceiling fastener is placed about 18 inches away from the wall so the drywall can flex as the bottom chord moves. Detail B uses molding secured to the ceiling rather than the wall, allowing the molding to move up and down with the truss. Arrows indicate vertical movement of the truss bottom chord and the floating molding.
