This cold-formed steel framed opening detail features boxed jambs constructed from two 600S162-54 studs connected with screws per 7/SF 5.40. The header consists of a 1200S200-97 track with 600T150-54 tracks top and bottom, reinforced by a 600T150-54 by zero-foot-ten-inch stiffener secured with six number eight screws on each leg and twelve number eight screws to the jamb. A 6-inch cripple stud matches the jamb with four number eight screws to the jamb, while top track connections utilize two number eight screws at twelve inches on center. The sill assembly incorporates an L one-and-a-half by one-and-a-half by 54-mil clip angle sized to stud depth less half an inch, fastened with three number eight screws on each leg. An optional stack joint is detailed per 7/SF 5.40 and is not allowed below windows, supported by boxed jambs below the stack joint matching the upper jambs. Base anchorage is provided per 1/SF 5.21, and a note specifies to not splice header or sill members.
