About this detail

Two connection options for the top of a non-bearing cold-formed metal stud wall allowing for structural deflection. Option A features a T150 top track matching the studs with a fifty-four mils minimum thickness for interior studs and sixty-eight mils minimum for exterior studs, leaving the studs unattached to the track below and incorporating a three-quarter inch gap secured with number eight sheet metal screws each side to each stud in the bottom half-inch of the track. Option B, designated for interior walls only, utilizes a sixty-eight mils minimum slotted slip track with allowance for a three-quarter inch deflection installed per manufacturer and ICC ES report recommendations. Wall coverings must be left unscrewed to the top track, and where sheathing does not extend to the structure, a strap and blocking must be provided at unsheated faces at four feet on center maximum.
