About this detail

A slotted deflection track connects to a concrete slab or fireproofed metal deck, accommodating vertical movement above the scheduled partition. At metal deck conditions, fifty-four mil Z-clips measuring two inches by two inches are spaced at a maximum of one foot four inches on center and fastened to the deck using two zero-point-one-hundred-forty-five-inch diameter Hilti X-DNI shotpins with one-inch embedment. Cavities are filled with minimum four pounds per cubic foot density mineral wool, which may be substituted with fire-rated acoustical sealant or minimum forty pounds per cubic foot cementitious fire retardant at acoustic conditions. Fire resistive joint spray is applied at the assembly joints, and two number eight screws secure each Z-clip to the partition framing.
