A roof load carrier for a vehicle, the carrier comprising:

• a rail which is fixable to the surface of the vehicle roof along a side edge of the roof, the rail having an upper support surface, and an elongate inner channel in and extendable along the rail, the channel having an opening outward toward the support surface of the roof rail;
• a transverse bar for being adjustably mounted in a position along the rail and for extending laterally from its mounting on the rail, the position of the transverse bar being displaceable on the support surface of the rail;
• a support foot on the transverse bar at the rail, and the foot including a foot surface which rests on the support surface of the rail;
• a fastening device for fastening the support foot to the rail, the fastening device comprising:
• a clamping plate disposed in the channel of the rail and having a threaded opening therein;
• a fastening bolt, including a head for being supported by the support foot of the transverse bar, and including a threaded shank which extends into the channel and into the opening in the clamping plate for being tightened in the threaded opening such that tightening of the bolt into the clamping plate tightens the boot head against the support foot and moves the clamping plate and the head of the bolt to clamp the foot and the rail;
• a plurality of holes arranged in a row in the rail, generally parallel to the channel and located to the side of the bolt;
• a securing pin on the support foot which extends into a selected one of the holes in the rail for additionally securing the foot and the transverse bar against shifting along the channel and the rail.
