ABSTRACT:
A vertically moving door of a truck loading dock includes a disconnectable horizontal joint that provides the door with a barrier position, wherein an upper section of the door can be separated from a lower section to create a ventilation area between the two. The ventilation area allows fresh outside air to enter the building, while the lower section remains at its lowermost position for safety and security. More specifically, the lower section serves as a barrier that helps prevent someone or something from accidentally falling through the doorway when a truck is not present at the dock. A lightweight, resilient strap can be attached to the lower section of the door to help protect that section from an otherwise damaging impact. A lattice of straps or a mesh can be installed across the ventilation area to help secure the building against theft.
