Attach a sport rack to the roof of a vehicle that has pre-installed mounting points with this Thule Kit. The Podium Foot Half Pack with 3101 Kit includes two Podium feet (half of the mounting kit) and two end caps. Why would you ever want only two feet? Maybe you broke one of your others and you want to save some cash instead of buying a set of four feet again, or you just want a backup. Be sure to pick up locks and square load bars; these Podium feet require both.
