The roller of a truck box roller tarp assembly is equipped with dependent loops of chain at spaced intervals along its length. Brackets, forming hooks, are secured to the truck box at a common elevation along one side. When the tarp is closed over the box opening, the roller loops hang below the hooks. The roller may be reverse rolled, using the conventional crank, to climb the tarp and bring the loops into engagement with the hooks. The now-constrained roller may be further reverse rolled, to tighten the tarp. The roller is then locked up by securing the crank to the truck box in conventional fashion.
