CROSSBAR-TO-VEHICLE COUPLER

A crossbar-to-vehicle coupler may include one or more locking pins operatively connected to a pivoting cover, such that moving the cover from an open to a closed position causes the locking pins to engage corresponding recesses in a base portion fixed to a vehicle rooftop. The coupler may include a selectable pitch interface for adjusting the pitch angle of the crossbar with respect to the coupler and/or a vehicle on which the coupler is mounted. An actuator of the coupler may convert motion of a tightening screw oriented parallel to the crossbar axis into a clamp tightening force oriented orthogonal to the crossbar axis. The tightening screw may be inaccessible when the cover of the coupler is in the closed position.
