This is a set of FOUR like new Yakima foot pads for use with the Yakima control tower. My set of control towers used the ROUND bars. I am unsure if it works with the other towers that Yakima makes. 

I bought these, and they work great! They have a snug fit on the vehicle and keep the control towers secure. 

The car I bought these for (Honda Crv 2004) I ended up selling to a friend 3 months after buying the landing pads, and the landing pads do not fit my new vehicle. 

NOTE: These do not come with the original package material or inserts such as instructions. With 8 screws and an Allen wrench included, installation is straightforward and took me about 15 minutes when I installed them.
