About this detail

Cold-formed steel ceiling framing at openings utilizes continuous ceiling joists sized per schedule spaced across structural members. Framing members consist of 400S162-68 studs where J1 is specified or 600S162-68 studs where J2 or J3 is specified, fitted with a T150 track matching the gauge and width of the ceiling joists. Openings are limited to a maximum dimension of 2 feet 6 inches by 3 feet 2 inches. Connection angles measuring 1 1/2 inches by 1 1/2 inches by 54 mil by 0 feet 2 1/2 inches long secure the framing with three number 10 sheet metal screws in each leg. Additional number 10 sheet metal screws fasten each flange typically. If the framed opening is less than 16 inches wide, typical stud size and flange receiving headers or sills remain per schedule.
