What is the purpose of a header in framing?

The purpose of a header in framing is to distribute the load above openings, such as doors and windows. When a wall is framed, openings need to be made for these features, which can potentially weaken the structural integrity of the wall. Headers are installed horizontally over these openings to span the distance and carry the load from the structure above.

By effectively redistributing the weight, headers ensure that the load is transferred to the vertical members, such as studs or columns, on either side of the opening. This prevents sagging or failure in the framing system caused by the absence of support where the wall has been interrupted by an opening. Properly sized and installed headers are essential for maintaining the safety and stability of a structure.
