A ______ is a vertical component used in wall framing.

A stud is a vertical component used in wall framing, typically made of wood or metal, and serves as the primary support for the wall structure. Studs are usually placed within the wall spacing, providing both structural support and a framework for attaching drywall or other wall coverings. They are essential in creating the walls of a building and determining the overall layout and strength of the structure.

Other choices describe different structural components; for instance, beams are horizontal elements that support loads from above, while joists are horizontal structures that provide support for floors or ceilings. A Lally column is a specific type of vertical support column used in basements or to support beams. These components play critical roles in construction but do not fulfill the same function as a stud in wall framing.
