A collapsible, corrugated damage prevention device for separating freight in transit in railroad cars, trucks, and the like is provided and includes an outer tube like member and a collapsible spreader core inside the outer tube and at right angles to the sides of the outer tube. One version provides an outer tube like member and a second tube like member inside and at right angles to the outer tube. Another version provides a U-shaped outer section with outwardly extending flanges covered with a cap sheet to provide a hollow interior. The sides of the void filler are scored to allow each side to be easily folded outwardly from the core member thus disposing the entire device in a flat configuration which can be easily stored when not in use.
