a crossbar and a pair of couplers configured to mount the crossbar on top of a vehicle such that a long axis of the crossbar is substantially horizontal and perpendicular to a longitudinal axis of the vehicle; wherein each coupler includes:
a crossbar clamp having a crossbar seat and a crossbar connector movable relative to the crossbar seat; anda crossbar clamp actuator comprising
a horizontally traveling wedge block having a ramped, downward-facing first slide surface, anda wedge follower coupled to and movable with the crossbar connector, the wedge follower having a second slide surface in frictional contact with the first slide surface of the traveling wedge block, such that substantially horizontal repositioning of the traveling wedge block causes the ramped first slide surface to urge the wedge follower downward, moving the crossbar connector downward relative to the crossbar seat. |
