Most Popular Foam Blocks for 2015 Mazda CX-9

It's doing the job of securing my kayak to my rackless prius, at a fraction of the cost. However, the instructions included along with the straps did not work for me. I spent a considerable amount of time adjusting things: the red straps that are supposed to go over the boat and secure on the bars were not long enough. The blue straps are much longer, so I am using the red straps to secure the bars to the car, through the open doors and cinched inside the car. I am using the blue straps to reach over the boat, and I decided to feed those into the car too- feels more secure than to attach them to the bars on top. The black straps for front and back strapping don't work for my car in the way shown, I had to jerry-rig. Overall I have figured out how to make it work, and I'm glad I didn't spend $xxx.xx on a serious rack system.

It's reliable and very easy to install. Trapped several different kayaks onto roof and driven long distance at top speed and no issue with kayak getting loose or moving around.
