Fits the bill!
We found these fairly easy to assemble with 2 sets of hands. Some parts didn't seem to fit together very well, so my husband held them in place while I tightened the nuts. Attaching them to our Aero Crossbars was much simpler, but I would have preferred the bottom bracket to be flat- bother vehicles have the flat aerodynamic crossbars.<br />We did install the with the longer part on the outsides of the vehicle, so they make a "W" on the roof of the car.<br />The problem for us, was the lack of instructions on how to tie down the kayaks. We have used the supplied straps for shorter trips, when our ratchet straps were not available, but I MUCH prefer our ratchet straps! We loop the strap around each kayak and cross under the crossbars. Essentially, the J carrier only holds the kayak on it's side, while the ratchet strap holds the kayak to the crossbars.<br />Overall, I think that if we looped the provided straps through the J carrier and over the kayak (just strapping to the J carrier), in combination with our aero bars, on a longer trip, these j carriers would be likely to fail. We will likely look at name-brand j-style carriers for something sturdier for the next season. I am still researching a better way to tie down our kayaks.
