When pulling sag damage, the shop will ______________________.

• A. Brace the high end and pull on the low end
• B. Block low end and pull down on high end
• C. Push down on high end and pull up on low end
• D. Pull up on high end and push down on low end

Answer: (B)

When correcting sag damage, you want to control how the panel moves by anchoring one part and adjusting the other. Blocking the low end holds that portion of the panel in place, so it doesn’t move, while pulling down on the high end brings the elevated area toward the fixed portion. This coordinated action levels the surface and closes the sag without creating new distortions. Pulling in the opposite directions or moving both ends without stabilization can further misalign the panel, which is why this approach—block the low end and pull the high end downward—is the correct method.
