Which component allows the frame to be propped at every stage of the lifting?

• A. Door jamb, and door header
• B. End wall parts
• C. Brace rods
• D. Eave strut

Answer: (D)

The main idea is to have a stable, continuous support at the top of the wall frame that can be used as a temporary prop as you lift and set each section. The eave strut provides that horizontal, rigid member at the eave line, giving a solid surface to attach temporary supports and rigging. As the frame is hoisted stage by stage, the eave strut can be left in place or adjusted to keep the frame square and plumb, allowing safe, incremental lifting without losing alignment. Other parts listed serve different purposes—door jambs and headers create openings, end wall parts belong to the end walls, and brace rods are used for bracing but aren’t the primary, always-present propping surface along the frame during lifting.
