1/2" spacers installed between the header pieces when fabricating exterior wall components is To strengthen the header correct option is D.
1/2" spacers are installed between the header pieces when fabricating exterior wall components to strengthen the header. A header is a horizontal structural member that supports the weight of the load above an opening, such as a door or window.
When a header is made from multiple pieces of lumber, the spacers help to distribute the load evenly and prevent the header from bending or sagging. A. So the finished header is the same thickness as the wall: This is not the primary reason for using spacers.
B. So nails do not protrude through the other side of the header: This is a concern, but it is not the main reason for using spacers. Spacers are primarily used to strengthen the header, and they also help to prevent nails from protruding through the other side of the header.
Therefore, the correct answer is **D. To strengthen the header.**
