Crossbars and front two "clamps" (sorry, I don't have a roof rack and don't know terminology) look almost identical to sportrack brand - Amazon link at bottom shows almost the exact product except it's branded. If that's not it, your search will be more thorough if you include the keyword "keyed" since they have locks on them. If the picture you took is of a 2nd gen focus coupe, then just keep in mind that the rack could be as old as the car, which would put it in 2008 and the rack may no longer be produced or the model may be discontinued. As for the back support with padded feet but no clamps, I have no idea. If it's an old model, they may have come with it, or may even be an extra/ accessory piece bought separately but needed because this model in the picture is a coupe, so all of the "clamps" had to go above the front seats' door frame. If you are looking to install on a sedan you would be fine without it, but with a coupe obviously they needed more support towards the rear of the rack.

I have one on mine! I love it, and was super easy to set up. I’ll get the details later today and edit this comment with them.

This is the one I used. It pinches on pretty well under the weather stripping of the doors, but I added a small self-tapping screw to each one just for piece of mind when I drive the freeway. All of that is hidden behind the weather stripping on each doorframe though. I love how it turned out
i used these. they fit perfect on two of my cars as they're universal. no issues ever. before i got these i had soft racks like a lot of guys are suggesting. but if you surf everyday, its gonna get old putting them on and taking them off.

Not sure about the length of the kayaks. The pink is a pelican and the green is a Lifetime. It is longer.
I use this {one}.(https://www.amazon.com/SportRack-SR1002-Complete-System-Black/dp/B00BHWMDSM)It's on sale too.
I have a fusion and let me tell you these cars are not made to carry kayaks so you have a few things to buy. I'm gonna attach everything I bought for you and I've had great results with it so far.
