Abstract: Strap holders for palletized cargo include one or more blocks, each having an upper surface, a lower surface, a front face and a vertical rear face. The front face includes an arcuate cavity that is dimensioned and configured to tightly conform to the upper rim of a given storage container. The vertical rear face includes a notch that is dimensioned to receive a cargo strap. As the strap is tightened around a container, each block cavity tightly grips the container rim while the notch prevents the strap from shifting or releasing.
