What structural elements support the header in an exterior window installation?

In an exterior window installation, the header is a crucial structural component that helps support the weight of the wall above it, transferring loads down to the framing below. The correct answer involves the use of jack studs and king studs, which work together to provide necessary support for the header.

Jack studs, also known as trimmer studs, are positioned directly beneath the header. They carry the load from the header down to the sole plate or bottom plate, allowing the weight to be properly distributed to the foundation. King studs, on the other hand, extend the full height of the wall and run on either side of the opening, providing additional support and stability. This combination ensures that the header remains secure and effective in bearing loads without risking structural integrity.

Other options, such as bottom rails and J channels, serve different purposes in window and siding applications rather than providing direct structural support for headers. Bottom rails are often related to other aspects of window framing or door assemblies, while J channels are used primarily to create a channel for siding or to finish edges, helping in moisture management rather than contributing to load-bearing capabilities. The mention of one-sided studs is not standard practice in framing window openings and doesn't apply to the structural requirements surrounding a header, which relies on a system
