An attachment assembly is provided for coupling a portable barricade to an overhead door, including a clamp, the clamp having a first surface and a second surface, the second surface facing the overhead door, a fastener passing through a clamp opening of the clamp and through an opening of the overhead door, a coupling member operably engaged with the fastener, and a biasing element positioned between the second surface of the clamp and the overhead door, wherein, when the coupling member is actuated in a first direction, the biasing element is compressed, shortening a distance between the clamp and the overhead door.
