About this detail

Cold-formed steel joist blocking connects to studs using either a Simpson L50 clip for six-inch joists or a Simpson L70 clip for eight-inch joists, secured with three number ten screws on each leg. As an alternative, the blocking web can be bent ninety degrees and fastened with three number ten screws to each leg. Solid blocking matches the joist depth and gauge, with flanges coped as needed to clear the joist flange lips. Tracks of the same gauge as the studs maintain a maximum one-half inch gap, featuring cut flanges and bent webs secured with two number ten sheet metal screws to the stud web.
