Which framing member is described as a ledge meant to keep out wood boring insects?

• A. Sill Plate
• B. Bridging
• C. Dried Wood
• D. Light-Gauge Framing

Answer: (A)

The bottom horizontal framing member that sits on the foundation and serves as the base for the wall is described as a ledge for the rest of the frame. It forms the base where studs are nailed and often provides the surface where protective barriers (like termite shields or flashing) are installed to help keep out wood-boring insects. That combination of being the base contact point with the foundation and hosting insect-preventive details makes it the framing member described as a ledge that keeps out insects. The other items refer to different roles: bridging stiffens framing between studs, dried wood isn’t a specific framing member, and light-gauge framing is a material type rather than a base ledge.
