I saw that I had a loose fitting and thought I'd take care of it when I got home. Of course, on the way home there was a CLUNK CLUNK CLUNK down the roof and it was this piece falling off. Had to ziptie the rack to the crossbar on that side to get down the mountain. Stopped in at a couple of local rack shops with no luck. Found this one on the Yakima site and had it in my hands a few days later. Exactly the same as the others on my rack and easy to install. Stoked to get the part and not have to buy a whole new rack.
