Jack studs are primarily used to support what structure in a wall?

Jack studs play a crucial role in supporting the header assembly in a wall structure. When a header is installed over an opening such as a door or window, jack studs are utilized on either side of the header to provide the necessary vertical support. They transfer the weight of the header and any load above it down to the sole plate or the floor framing below.

The header itself is designed to bear the load that would otherwise be supported by the wall in that area. By using jack studs, builders ensure that the installation remains structurally sound and can effectively carry the stresses imposed on the header by the roof or floors above. The use of jack studs is integral to maintaining the integrity of the openings in a framed wall, allowing for the creation of functional spaces without compromising overall safety and stability.
