About this detail

A fire-rated partition wall head condition is oriented perpendicular to a concrete floor deck. A deep leg runner track is fastened with number ten by one-inch sheet metal screws at twenty-four inches on center to the plate, allowing vertical clearance for the runner to deflect. Continuous eighteen-gauge minimum steel profiles provided by the deck manufacturer are installed on both sides of the wall. Four pounds per cubic foot mineral fiber safing with a foil back is friction-fitted at the deck level. Firestop sealant with a half-inch minimum depth is applied to each side, backed by packed mineral fiber safing.
