Abstract: A load conformable tarp includes a plurality of strap adjustment assemblies for adjusting the effective length of associated adjusting straps. Each adjustment strap assembly includes an adjustment assembly for adjusting the length of an associated adjustment strap, as well as a locking mechanism for securing a free end of the adjusting strap, the other end being fixed with respect to the tarp base material. Each adjustment assembly preferably includes a pulley throughwhich one end of the adjustable strap is looped, one end of the adjustment strap preferably being fixed to the base material, the other end being free and configured to be engaged in various positions by the locking mechanism, thus forming an adjustable strap loop of variable size.
