Load-carrying members for vehicle roofs

A load-carrying member for use with a vehicle rack, comprising:

• a body having a load-bearing surface, wherein the body includes a clamp defining a first axis and configured to engage a crossbar mounted to a vehicle roof with the crossbar extending along the first axis;
• and
• an arm pivotably mounted to the body, wherein the arm is configured to pivot about a second axis that is transverse to the first axis between a first position in which the arm is proximate the load bearing surface and a second position in which the arm is transverse to the load-bearing surface, wherein the body and the arm in the second position collectively form a cradle that is at least generally shaped and at least generally oriented like a letter J;
• wherein the arm has first and second elongate portions spaced laterally from each other, wherein the arm includes an opening therethrough, wherein the opening is opposingly bounded by the elongate portions, and wherein the at least one projection extends from the arm and at least generally into the opening to divide the opening into a distal region and a proximal region linked by a gap.
