1. A method of setting up an auxiliary device to be mounted on a rail, comprising the steps of:
positioning a section of rail having a predetermined profile between a blade and a clamp member, the clamp member having an axis generally perpendicular to an axis of rotation of the blade; rotating the blade and an eccentric rotation hub into predetermined first rotational positions; securing the eccentric rotation hub in place with a fastener; rotating the blade to a second rotational position; rotating the eccentric hub to a predetermined minimum torque value; and securing the fastener to the eccentric rotation hub; wherein the eccentric hub is rotatable about a first axis of rotation and the blade is rotatable about a second axis of rotation, the first axis being parallel with, but spaced from the second axis of rotation. |
