When lifting panels from inside the building, the head or top of the panel should be nearest to which edge?

• A. Inside edge of the building
• B. Roof edge
• C. Corner joint
• D. Outside edge of the building

Answer: (D)

When lifting panels from inside, position the top so it is nearest the outside edge. This orientation uses gravity to help the panel tilt outward toward its final exterior face, while keeping the top clear of interior walls, utilities, and other obstacles. It also gives better control of the rotation so the panel seats flush with the exterior once raised. If the top were toward the inside edge, the panel could swing into interior elements; toward a corner joint or the roof edge increases the chances of binding, misalignment, or interference with other components.
